Clients subscribed to these notifications will receive updates on both definitively resolved HTLCs and confirmed bitcoin transactions, allowing them to construct a canonical ledger for coin movements through their C-Lightning node. ● C-Lightning 0.9.3 is the project’s newest minor release. This week’s newsletter includes the usual dashboard and action items, a link to discussion about generalized Bitcoin contracts over Lightning Network, a brief description of a recently-announced library for scalability-enhancing BLS signatures, and some notable commits from the Bitcoin Core, LND, and C-Lightning projects. 18877 is the first step towards support for serving compact block filters on the P2P network, as specified in BIP157. ● How do light clients using compact block filters get relevant unconfirmed transactions? 4715 adds a –reset-wallet-transactions configuration parameter that will remove all onchain transactions from LND’s wallet and then start a rescan of the block chain to repopulate the wallet. The decline in prices could be attributed to factors including increasing network congestion, rising transaction fees, or an incorrectly tagged US Government wallet dumping a large position in a significant sell order. ● Review proposed BIP322 for generic message signing: 바이낸스 (Source Webpage) this recently-proposed BIP will allow users to create signed messages for all currently-used types of Bitcoin addresses, including P2PKH, P2SH, P2SH-wrapped segwit, P2WPKH, and P2WSH.
Gregory Maxwell has asked the Bitcoin protocol development mailing list for proposed soft fork solutions to the attack before he proposes his own solution. Of course, actual enforcement of the soft fork will depend on it gaining broad support among users-and users may decide to use an alternative activation mechanism. Alternative recommendation engines can return their own scored recommendations, and the user (or their software) can decide how to aggregate or otherwise use the scores to actually decide which nodes should receive channel open attempts. In short, please consider performing extra diligence on any software or service to which you will entrust the creation of non-reversible Bitcoin transactions. Also included are our regular sections with summaries of notable improvements to clients and services, announcements of releases and release candidates, and changes to popular Bitcoin infrastructure software. Notable changes this week in Bitcoin Core, C-Lightning, Eclair, LND, Rust-Lightning, libsecp256k1, Hardware Wallet Interface (HWI), Bitcoin Improvement Proposals (BIPs), and Lightning BOLTs.
● Lightning Labs announces Faraday for channel management: Faraday is a tool for LND node operators that analyzes existing channels and makes recommendations to close problematic or under-performing channels. ● Bitcoin Core 0.20.0rc1 is a release candidate for the next major version of Bitcoin Core. 18808 causes Bitcoin Core to ignore any P2P protocol getdata requests that specify an unknown type of data. Several mathematical schemes have been proposed that would produce signatures for keys whose Y coordinates could be inferred without the additional bit (which is currently the only data contained within a prefix byte). Cryptocurrency markets experienced a slight increase in trading on Friday due to positive weekly unemployment data in the US. Like other currencies, products, or services within a country or economy, Bitcoin and other cryptocurrency prices depend on perceived value and supply and demand. Distributed finance, powered by immutable smart contracts, can evolve to become more capital efficient and robust enough to provide necessary financial services at scale, in a completely non-custodial environment. At the time of writing, Binance had a market cap of more than $56 billion and ranks behind only Bitcoin, Ethereum, and USD Tether in terms of market cap. ● Transaction fees remain very low: Anyone who can wait 10 or more blocks for confirmation can reasonably pay the default minimum fee rate.
First, the transaction fee is included in the hash in order to allow hardware wallets or offline wallets to ensure they aren’t being tricked into sending excess fees to miners. The only solutions, besides wallets abandoning message signing support, are for wallet developers to agree on a standard and then widely implement it. 4171 updates the hsmtool command with a new dumponchaindescriptors parameter that prints the output script descriptors for the keys and scripts used by C-Lightning’s onchain wallet. ● Lightning-based messenger application Juggernaut launches: In a blog post announcing the first release of Juggernaut, John Cantrell describes how the messaging and wallet features are built using keysend payments. Proof-of-work was the first consensus algorithm that managed to prove itself, but it isn’t the only consensus algorithm. The protocol should even be forward compatible with future segwit versions, such as bip-taproot and bip-tapscript (with some unresolved limitations related to time locks). The previous standard protocol uses four transactions.
