New England New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/ NewEnglandcoin Symbol: NENG NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones. Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt. 1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377 NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number Bitcoin Fork - Suitable for Home Hobbyists NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs. The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software. Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%. NENG v1.4.0 release enabled CPU mining inside android phones.

There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG. We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

Hi all, Can anyone please tell me if my procedure is correct and enough. I've always heard and read that I must disconnect from the internet when creating Electrum Wallets, to keep away from hacks, viruses, malware or having my bitcoins stolen. I have created electrum wallets and bitaddress paper wallets yesterday. Though I dont know much about its technicalities, I just followed simple procedures I've read online.
downloaded electrum exe installer and bitaddress (from github)
save them in my usb
disconnected my laptop from the internet
uninstall and reinstall Windows 10 (I have windows installation files too, in my usb)
created Electrum wallet, write the seed in a paper. save the wallet file in my usb.
created bitaddress paper wallet, write the Public Key and Private Key in a paper (not print). have checked the spellings, capitalizations multiple times.
uninstall and reinstall windows 10 again, scanned my usb, then connect again to the internet.
From time to time, somewhere on social media, the FUD appears about the Cardano project. We can see opinions like “Cardano is just a wallet”, “Cardano never launches main-net”, “PoS will never work”, or “it’s just white-paper”. These are all opinions based on impatience, ignorance of the depth and complexity of the project, or the inability to objectively assess the matter. Often, this FUD is caused intentionally by supporters of a competing project. Just to make competitors more relevant. Let’s look at some facts in today’s article. Cardano is a very complex project Cardano is the first project that is based on formal method development and it is built as a mission-critical project. The IOHK team has done thorough research on all areas related to blockchain and distributed networks. The team studied existing works and sought the best solutions to technical problems in a real environment. The team has published many scientific studies that have undergone a rigorous review and today have countless citations. The team starts production software development only after the specifications are available. The critical parts of the project are written in Haskell. Haskell is a functional programming language that doesn’t allow any side-effects. Blockchain incorporates technological, economic and social components. It is a system that aims to replace the current financial system and compete with the current IT giants. Such a project cannot be done just by giving you a bunch of programmers to make you a mix of Bitcoin and Ethereum. Without an emphasis on overall quality and details, such a system will never work reliably in the long term. On the other hand, such a project can be delivered in just one year. Do we need it? Cardano took a different and more challenging path. If the team simply delivered another blockchain, it would rank among hundreds of similar projects. It was necessary to put together experts to cryptography, software security, distributed networking, threat modeling, protocol design, game theory, operating systems, designers of programming languages, economy, and of course, software architects and programmers. All these people had to work together to deliver the network that would be great in all respects. These are people who are respected leaders in their field and often at the top of their careers. If one network is to serve the whole world, it must be capable of global scalability. It must never stop and allow all people on the planet to freely engage in network consensus. Including cheaters. Such a network will be massively attacked. Cardano must endure it and continue to function smoothly. It is a more complex task than you might think. And believe me, there are not many people in the world who could fully understand that in all details. It takes a lot of time and effort to build such a project. No existing project is capable of mass adoption and is at the same time demonstrably secure and sustainable in the long term. Cardano will be. Global, open, public, permissionless networks are brand new. There was nothing like that before Bitcoin. The first generation of cryptocurrencies suffers from technological imperfection. Often they are in the experimental phase and are improving in full operation. In the case of Bitcoin, everybody is scared to change the first layer, as there is a legitimate concern that something will fail. The second layer can improve something, but it will always creak. The quality of the project is directly related to the quality of the team and the time spent on research, experimentation, implementation, and testing. These phases can’t be underestimated or omitted. If you do, it will fire back at you later. We can see thousands of projects on CoinMarketCap, but few are worth the attention. In ten years, there will be maybe only three of them. Transparency Cardano is one of the most transparent projects in the crypto. CEO of IOHK, Charles Hoskinson, does AMA and status updates very often. Sometimes several times in one month. During AMA you can ask him literally what you want. Other team members have recently started updating us as well. Cardano, as one of the few projects, has all its scientific works publicly available. Anyone can look into them and critically review the content. The number of works increases regularly. If anyone has doubts about the quality of the project, they can try to find some mistakes in these works. And believe me, it will be hard. This work by itself has already pushed the crypt forward by a great deal. So far, nobody has worked out exactly what the ledger is and how it should work, whether PoW is really safe, how to write smart contracts safely, how to create a sustainable economic model, etc. All other projects can benefit from this work. Do not believe that? Well, we can give you one of the many possible examples. Aggelos Kiayias is the chair in cybersecurity and privacy at the University of Edinburgh. His research interests are in computer security, information security, applied cryptography, and foundations of cryptography with a particular emphasis on blockchain technologies and distributed systems, e-voting and secure multiparty protocols, as well as privacy and identity management. He joined IOHK in 2017 as a chief scientist through a long-term consulting agreement between IOHK and the University of Edinburgh, where he is also the director of the Blockchain Technology Laboratory. Aggelos is one of the brains behind Ouroboros PoS. It is relatively easy to find the works in which he participated and the number of citations. You can just open any scientific paper from IOHK, check the list of authors and find the number of citations. You can also easily verify there is no competitor in the whole crypto. Of course, the important thing is to get the scientific work into the source code. And that happens. You can check out GitHub for all the project repositories. Be careful, many people and aggregation sites for some reason only look at the cardano-sl repository. Look at them all! We understand that if you are not a programmer, it will be difficult to judge the quality of code. You just have to educate yourself here if you really want to know what is going on on GitHub. Activity is compared by the number of commits, which is some modification of the source code. Usually, a new piece is added or something old is deleted. You can easily look at the details of each repository. You can see how many people are actively developing the code, you can see what they are working on, how often they add changes, and more. Let’s have a look at the Ouroboros-network repository. Shelley protocol is written in Haskell. The quality and activity of the project can also be judged well by the number of new and already solved issues. If you are in any doubt about any project, learn how to read GitHub activity. In the case of the Cardano project, be absolutely calm. The activity is one of the highest, if not absolutely highest, in the entire crypto-sphere. If anyone tells you otherwise, please refer to the IOHK library and GitHub. You can even check out the site where all the Cardano GitHub data is altogether. Delays are usual in software development We have already talked about how complex the Cardano project is. Believe me, delays are a common thing when creating software. There are plenty of well-described reasons for that. Every software engineer could confirm that. Let’s dive into it just a bit. An accurate estimate during making a software plan is nearly impossible. You always have a bunch of items and tasks for a bunch of engineers. Tasks often overlap and depend on each other. To make it worse, tasks are mostly abstract and it is often hard to predict all possible obstacles. You can measure the performance of the team to improve time estimates but still, you never know when a plan is going to fail due to unexpected problems. Team members have to work together years to have solid certainty about all estimates. Cardano team is international so coordination might a bit more demanding. When some small and seemingly unnecessary tasks are skipped at the beginning, it can happen that there will be unexpected delays just because they have to be handled later. And sometimes, plan or priorities changes. Many engineers are very optimistic when asked how long some tasks could take. They are often wrong. In reality, tasks are usually more complex than engineers think. Team members change over time. IT gurus are a special kind. They like to change jobs very often. If a team expert leaves the team, it may take longer to find an adequate replacement. This also causes a delay. The IOHK team has a lot of members. Delivering 90% of functionality can be relatively easy compared to the last 10%. The biggest problems can arise at the end of development when all the individual components are tested together. Problems encountered at the end of development must be addressed. This often means changing a lot of things or redesigning something. Testing itself is very demanding as a global network must be simulated or the setup. In addition, the software must run on different versions of operating systems. Let’s have a look at some famous software delays. Mac OS X was developed under the name Rhapsody and it was 1997. Version 1 release arrived after 4 years. Windows Vista was originally planned to ship in 2003. Thre was 3 years delay. If you look for more examples, you will find many. A project like Cardano can’t simply be done in a year or two. If Shelley is launched this year, it will actually be very fast. If you look at examples from the crypto-world, you will see a big delay in the delivery of Ethereum 2.0. Count how long the Lightning Network has been built. And look at how many errors and failures we’ve seen. These failures have often led to large financial losses. If you were looking for reasons, you would find that it is caused by a badly designed or implemented software. Of course, it is in the best interest of the team to deliver Cardano to the market as quickly as possible. But certainly not at the cost of technical imperfections. This is not a race against time. A year or two has almost no role if we can see a really good and functional, secure network capable of mass adoption. Learn patience. Software delivery has its phases. First, everything has to be well thought out and designed. The team must be built. Then research and experiments are carried out. During this, the first source code can be written. Then the testing phase takes place. Only after all this can the network reach the public. Testnet has been launched Testnet has been running since the end of 2019. And it is a great success. The team expected an interest of about 100 pool operators. There are over 1000 registered pools. The network is stable and runs almost without problems. People’s interest in Cardano is huge. Community people are working on useful tools. Just check adapools.org or pooltool.io. Pool operators have no problem communicating with the team. All problems are gradually solved and many of them very quickly. Everyone in the world can run their own node and become a pool operator. Who claims that Cardano is just a wallet, he should try it for himself. Do you like smart contracts? Do you want to write one? Well, you can try it. Cardano will have Plutus and Marlowe. You can try both of them on the online playground. No Lambo, sorry Cardano’s not here to get you a Lambo. Charles promised to deliver the most decentralized network, secure smart contracts, project governance and resolved scalability. All based on scientific research. If such a network can be delivered and people adopt it, only then can we say that the team has succeeded. Will that affect the price of ADA coins? Definitely yes. The team must be fully focused on development. Not for the price. So do not complain about the price. Nobody is going to help you. Only you are responsible. Summary IOHK is one of the best teams in the crypto. There is a lot of work behind this team. Everyone can look at it. Nothing is patented. Everything is open-source. We cannot forget to Emurgo and Cardano Foundation. These entities, too, are completely transparent, and much work can be seen behind them. See for yourself. If someone doesn’t see it and claims that Cardano is just a wallet, he must be blind and deaf. The delays in delivering such complex software as Cardano are quite common. Rather, it would be appropriate to say that the team is moving very fast. Cardano has come so far that neither Microsoft nor IBM will be able to compete. Thanks to Cardano, the whole crypto will move up a lot and be more relevant. If you don’t believe anything we have written, you have many opportunities to check it out. So don’t believe us, verify yourself. You can read the full article with all links and images here:https://medium.com/@Cardanians_io/cardano-is-not-just-a-wallet-2c27eab9fac7
Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
How secure is my plan: I want to generate a long-term cold storage wallet using Ian Colemans tool and regular dice
Hi there! I have been into Bitcoin for a few years now, but I took a break from the topic and didn't keep up to date with the latest technology. When I was still active, paper wallets were still the hot new stuff! I do own a Trezor Model T, but I want to be EXTRA paranoid and not trust the hardware wallet to generate a wallet for me. The chances of this are slim, but what if the hardware was modified to generate a wallet that another party has access to? Now, I want to generate a highly secure long-term cold storage wallet for a relatively large amount of Bitcoin and only rely on myself. I already read quite a bit about the topic, but because of my inexperience I have a hard time understanding just how secure the method really is. Then I found this video: https://www.youtube.com/watch?v=j5nejoEGWFw He generates the mnemonic by rolling dice and putting in the results as entropy into Ian Coleman's tool. From that, I created a plan that currently looks like this:
Wipe Trezor Wallet and install the latest image from official website
Originally Trezor was developed for Bitcoin. Now it supports more different cryptocurrencies including Ethereum. This ETH wallet will work in tandem with your MyEtherWallet.Trezor is famous for the features that make it very secure. It provides 2-factor authentication, advanced cryptography and the opportunity to check transaction details before you confirm. On the other hand, there are a couple of disadvantages. Such as the cost: the Trezor wallet is pretty expensive. If you are not a regular user you probably should consider cheaper wallets. Also, it takes time to access your holdings with this wallet.Thus using Trezor as Ethereum wallet may be a little inconvenient if you are a common user.
Ledger Nano S
Ledger Nano S is also a hardware wallet. It connects with any computers via USB. The most important feature of this wallet is security. As well as Trezor it provides 2-factor authentication. Aside from this, this Ethereum wallet has a PIN code to secure the device itself and also you can back up your account on the recovery sheet. Ledger Nano S gives users an opportunity to check details of transactions before the confirmation. The main disadvantage of the Ledger Nano S wallet is the price. It is cheaper than Trezor, but it is still pricey.
KeepKey is a hierarchical deterministic (HD) wallet. It is also in the group of hardware wallets. KeepKey supports a lot of cryptocurrencies.The fact that this is an HD wallet allows users to generate private keys in an unlimited quantity. Undoubtedly this adds to the security level. Moreover, with the help of this device, you review and confirm every transaction. You can also set up a PIN code and a recovery sentence to make sure your holdings are secured enough. It is easy to start using the KeepKey wallet. You need to download a couple of applications. One is to create a wallet. And with the help of the second one, you will be able to connect to KeepKey through Chrome. Talking about the disadvantages we should mention the price. It is one of the most expensive wallets on the market to use it as ETH wallet.
The great thing about web wallets is that you can easily access them. All you need is an internet connection.
Unlike the most part of hardware wallets, MyEtherWallet is free. Nonetheless, it provides a high level of security by allowing users to store their keys on their own computers. There is no necessity to give any private information when creating a wallet.This Ethereum wallet interrogates with some hardware wallets such as Ledger Nano S and Trezor. Also, this platform gives an opportunity to write smart contracts. In addition, MyEtherWallet provides automatic back up. So users should not remember about this by themselves.Moreover, it’s possible to get a paper Ethereum wallet by going to the “Wallet Info” section. https://preview.redd.it/j7wzg5ki0mh31.png?width=1088&format=png&auto=webp&s=41383744e961877ba6acbf128be7fdcb2f4baf77
First of all, Coinbase is an exchange platform. Usually, it is not recommended to store cryptocurrency on the stock platforms. But Coinbase is often considered to be an exception. This platform has a wallet that is suitable for use as ETH wallet. It is easy to use and has an intuitive interface. One of the major drawbacks of this wallet is that users don’t control their private keys.
MetaMask is not just a popular Ethereum wallet. It is a browser extension. It can be installed on a number of browsers such as Chrome, Firefox, and Opera. This form allows accessing your holdings easily.The good thing is that you don’t need to provide personal information for the registration. Also, there is an opportunity to store the private key on your computer.
There are wallets that are made in the form of a software program. They can be installed on your device. Such wallets are called Desktop Wallets.The security level of these wallets is not as good as of hardware ones.
Exodus is a multicurrency wallet. So it can become your ETH wallet.It is famous for its user-friendly interface. It is a good wallet for those who only start their journey into the cryptocurrency world. Exodus supports ERC20 tokens.Users store their private keys on their computers. This increases the security level. Exodus has a backup feature. The drawbacks of Exodus are that there is no possibility to add any custom tokens and a small list of ERC20 tokens.
Mist is the official Ethereum wallet. So it is a full node wallet. Full node wallet downloads the whole Ethereum blockchain on users’ computers. In other words, it downloads all the data about the ETH network. This type of wallet makes any user a full-fledged member of the blockchain. Mist has developed the way to allow users to interact with their ETH storage easily. It is free. Users don’t provide private information during the process of registration. The only way to access your wallet is to use a password. Your private keys are stored on your computer.The Mist wallet supports smart contracts.
Sometimes it is more convenient to use a mobile wallet, which can be installed on your mobile devices. This type of wallets provides quicker access to your storage wherever you are. Mobile wallets are easier to use than desktop ones, but it is riskier.
Jaxx is free. It supports a lot of cryptocurrencies including ETH. It can work on different platforms such as Linux, Windows, and OSX. There is also an extension for Chrome browser. The interface of Jaxx wallet is simple and good to use. However, the security of this wallet raises some questions.
Paper wallets allow printing private keys on paper. And this printed document is used as a wallet. These wallets are not that easy to access. Although the level of security is relatively high.
In case you are looking for a way to store your ETH in the most secure Ethereum wallet, but you are not ready to pay for a hardware one, try ethaddress. This wallet is free. It provides a high level of security.
The core of this key-generating wallet is 99% identical to the well-considered bitaddress.org.First of all, it’s necessary to download this website from Github, unpack and open the index.html file directly from your computer. The code version control allows to significantly simplify the mutual verification of the executable code. For more security, disconnect from the Internet at the time of creating your wallet.
How to keep your wallet in security?
Whatever wallet you choose you want it to be as secure as possible. Here are some ideas on how to achieve this:
Choose a wallet that suits your requirementsAll wallets are aimed at different goals and ways to use. Some of these wallets offer high security, some provide you with easy access for fast trading. Therefore, you should choose exactly what suits your needs best.
Keep your private key safeAlways make sure that your private key is secure and is stored in a safe place. Moreover, do not share your private keys. No, not with friends. Not even with your parents.
Set up 2-factor authenticationSome wallets offer this feature to increase the security of your coins. Do not ignore 2-factor authentication, set it up for extra confidence in protection against theft.
Backup, backup, and backupNothing protects you better from unforeseen accidents than a good old backup. This way you can keep access to your coins.
Store your funds offlineWith all the security levels offline wallets are still the most secure ones. Therefore, it is better to keep large amounts of ETH coins only on offline wallets.

Lastupdated2018-01-29 This post is a collaboration with the Bitcoin community to create a one-stop source for Lightning Network information. There are still questions in the FAQ that are unanswered, if you know the answer and can provide a source please do so!
Lightning Network White Paper - The protocol has changed since this original paper, but covers the mid-level mechanics of the Lightning Network with an emphasis on the smart contracts that make it trustless
If you can answer please PM me and include source if possible. Feel free to help keep these answers up to date and as brief but correct as possible
Is Lightning Bitcoin?
Yes. You pick a peer and after some setup, create a bitcoin transaction to fund the lightning channel; it’ll then take another transaction to close it and release your funds. You and your peer always hold a bitcoin transaction to get your funds whenever you want: just broadcast to the blockchain like normal. In other words, you and your peer create a shared account, and then use Lightning to securely negotiate who gets how much from that shared account, without waiting for the bitcoin blockchain.
Is the Lightning Network open source?
Yes, Lightning is open source. Anyone can review the code (in the same way as the bitcoin code)
Who owns and controls the Lightning Network?
Similar to the bitcoin network, no one will ever own or control the Lightning Network. The code is open source and free for anyone to download and review. Anyone can run a node and be part of the network.
I’ve heard that Lightning transactions are happening “off-chain”…Does that mean that my bitcoin will be removed from the blockchain?
No, your bitcoin will never leave the blockchain. Instead your bitcoin will be held in a multi-signature address as long as your channel stays open. When the channel is closed; the final transaction will be added to the blockchain. “Off-chain” is not a perfect term, but it is used due to the fact that the transfer of ownership is no longer reflected on the blockchain until the channel is closed.
Do I need a constant connection to run a lightning node?
Not necessarily, Example: A and B have a channel. 1 BTC each. A sends B 0.5 BTC. B sends back 0.25 BTC. Balance should be A = 0.75, B = 1.25. If A gets disconnected, B can publish the first Tx where the balance was A = 0.5 and B = 1.5. If the node B does in fact attempt to cheat by publishing an old state (such as the A=0.5 and B=1.5 state), this cheat can then be detected on-chain and used to steal the cheaters funds, i.e., A can see the closing transaction, notice it's an old one and grab all funds in the channel (A=2, B=0). The time that A has in order to react to the cheating counterparty is given by the CheckLockTimeVerify (CLTV) in the cheating transaction, which is adjustable. So if A foresees that it'll be able to check in about once every 24 hours it'll require that the CLTV is at least that large, if it's once a week then that's fine too. You definitely do not need to be online and watching the chain 24/7, just make sure to check in once in a while before the CLTV expires. Alternatively you can outsource the watch duties, in order to keep the CLTV timeouts low. This can be achieved both with trusted third parties or untrusted ones (watchtowers). In the case of a unilateral close, e.g., you just go offline and never come back, the other endpoint will have to wait for that timeout to expire to get its funds back. So peers might not accept channels with extremely high CLTV timeouts. -- Source
What Are Lightning’s Advantages?
Tiny payments are possible: since fees are proportional to the payment amount, you can pay a fraction of a cent; accounting is even done in thousandths of a satoshi. Payments are settled instantly: the money is sent in the time it takes to cross the network to your destination and back, typically a fraction of a second.
Does Lightning require Segregated Witness?
Yes, but not in theory. You could make a poorer lightning network without it, which has higher risks when establishing channels (you might have to wait a month if things go wrong!), has limited channel lifetime, longer minimum payment expiry times on each hop, is less efficient and has less robust outsourcing. The entire spec as written today assumes segregated witness, as it solves all these problems.
Can I Send Funds From Lightning to a Normal Bitcoin Address?
No, for now. For the first version of the protocol, if you wanted to send a normal bitcoin transaction using your channel, you have to close it, send the funds, then reopen the channel (3 transactions). In future versions, you and your peer would agree to spend out of your lightning channel funds just like a normal bitcoin payment, allowing you to use your lightning wallet like a normal bitcoin wallet.
Can I Make Money Running a Lightning Node?
Not really. Anyone can set up a node, and so it’s a race to the bottom on fees. In practice, we may see the network use a nominal fee and not change very much, which only provides an incremental incentive to route on a node you’re going to use yourself, and not enough to run one merely for fees. Having clients use criteria other than fees (e.g. randomness, diversity) in route selection will also help this.
What is the release date for Lightning on Mainnet?
Would there be any KYC/AML issues with certain nodes?
Nope, because there is no custody ever involved. It's just like forwarding packets. -- Source
What is the delay time for the recipient of a transaction receiving confirmation?
Furthermore, the Lightning Network scales not with the transaction throughput of the underlying blockchain, but with modern data processing and latency limits - payments can be made nearly as quickly as packets can be sent. -- Source
How does the lightning network prevent centralization?
How would the lightning network work between exchanges?
Each exchange will get to decide and need to implement the software into their system, but some ideas have been outlined here: Google Doc - Lightning Exchanges Note that by virtue of the usual benefits of cost-less, instantaneous transactions, lightning will make arbitrage between exchanges much more efficient and thus lead to consistent pricing across exchange that adopt it. -- Source
How do lightning nodes find other lightning nodes?
Does every user need to store the state of the complete Lightning Network?
According to Rusty's calculations we should be able to store 1 million nodes in about 100 MB, so that should work even for mobile phones. Beyond that we have some proposals ready to lighten the load on endpoints, but we'll cross that bridge when we get there. -- Source
Would I need to download the complete state every time I open the App and make a payment?
No you'd remember the information from the last time you started the app and only sync the differences. This is not yet implemented, but it shouldn't be too hard to get a preliminary protocol working if that turns out to be a problem. -- Source
What needs to happen for the Lightning Network to be deployed and what can I do as a user to help?
Lightning is based on participants in the network running lightning node software that enables them to interact with other nodes. This does not require being a full bitcoin node, but you will have to run "lnd", "eclair", or one of the other node softwares listed above. All lightning wallets have node software integrated into them, because that is necessary to create payment channels and conduct payments on the network, but you can also intentionally run lnd or similar for public benefit - e.g. you can hold open payment channels or channels with higher volume, than you need for your own transactions. You would be compensated in modest fees by those who transact across your node with multi-hop payments. -- Source
Is there anyway for someone who isn't a developer to meaningfully contribute?
Sure, you can help write up educational material. You can learn and read more about the tech at http://dev.lightning.community/resources. You can test the various desktop and mobile apps out there (Lightning Desktop, Zap, Eclair apps). -- Source
Do I need to be a miner to be a Lightning Network node?
Do I need to run a full Bitcoin node to run a lightning node?
lit doesn't depend on having your own full node -- it automatically connects to full nodes on the network. -- Source LND uses a light client mode, so it doesn't require a full node. The name of the light client it uses is called neutrino
How does the lightning network stop "Cheating" (Someone broadcasting an old transaction)?
Upon opening a channel, the two endpoints first agree on a reserve value, below which the channel balance may not drop. This is to make sure that both endpoints always have some skin in the game as rustyreddit puts it :-) For a cheat to become worth it, the opponent has to be absolutely sure that you cannot retaliate against him during the timeout. So he has to make sure you never ever get network connectivity during that time. Having someone else also watching for channel closures and notifying you, or releasing a canned retaliation, makes this even harder for the attacker. This is because if he misjudged you being truly offline you can retaliate by grabbing all of its funds. Spotty connections, DDoS, and similar will not provide the attacker the necessary guarantees to make cheating worthwhile. Any form of uncertainty about your online status acts as a deterrent to the other endpoint. -- Source
How many times would someone need to open and close their lightning channels?
You typically want to have more than one channel open at any given time for redundancy's sake. And we imagine open and close will probably be automated for the most part. In fact we already have a feature in LND called autopilot that can automatically open channels for a user. Frequency will depend whether the funds are needed on-chain or more useful on LN. -- Source
Will the lightning network reduce BTC Liquidity due to "locking-up" funds in channels?
When setting up a Lightning Network Node are fees set for the entire node, or each channel when opened?
You don't really set up a "node" in the sense that anyone with more than one channel can automatically be a node and route payments. Fees on LN can be set by the node, and can change dynamically on the network. -- Source
Can Lightning routing fees be changed dynamically, without closing channels?
Yes but it has to be implemented in the Lightning software being used. -- Source
How can you make sure that there will be routes with large enough balances to handle transactions?
You won't have to do anything. With autopilot enabled, it'll automatically open and close channels based on the availability of the network. -- Source
How does the Lightning Network stop flooding nodes (DDoS) with micro transactions? Is this even an issue?
