This Research Will Perfect Your Bitcoin: Read Or Miss Out

● Backdoored VM images: a user on Reddit posted about losing funds after using an AWS image that came with a Bitcoin full node already installed and synced to a recent block. This week’s newsletter contains a warning about backdoored VM images. This week’s newsletter summarizes the CoinPool payment pool proposal and the WabiSabi coordinated coinjoin protocol. This week’s newsletter links to a discussion about routed coinswaps and includes our regular sections with summaries of questions and answers from the Bitcoin Stack Exchange, releases and release candidates, and notable changes to popular Bitcoin infrastructure software. 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. Also included are our regular sections with notable changes to services, client software, and infrastructure software. This is a reminder that you should only install software from trustworthy sources. In short, please consider performing extra diligence on any software or service to which you will entrust the creation of non-reversible Bitcoin 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.

19743 add a new maxapsfee (“max avoid partial spends fee”) configuration option to specify the maximum amount of extra fee you’re willing to pay to avoid partial spends when the existing avoidpartialspends configuration option is disabled. 1: partial spend avoidance is completely disabled to optimize for faster fee calculations, which may be useful for very large wallets with many UTXOs. Using taproot, this allows the cooperating participants to operate protocols such as LN or vaults using UTXOs that are indistinguishable from single-key UTXOs, improving both participant privacy and onchain scalability. ● Adding instead of concatenating hashes in Merkle trees Pieter Wuille breaks down a variety of issues to consider regarding the idea of combining hashes in a merkle tree using an operation such as addition instead of the concatenation that Bitcoin currently uses. ● C-Lightning 0.9.2rc1 is a release candidate for the next maintenance version of C-Lightning. ● C-Lightning 0.9.2 is the release for the next maintenance version of C-Lightning.

● How will the migration tool from a Bitcoin Core legacy wallet to a descriptor wallet work? After Bitcoin Core developers finish working on the upcoming 0.21 release, it’s likely that the results of this survey will help them choose the activation parameters that will be used for taproot in a subsequent release. ● Taproot activation survey results: Anthony Towns received survey responses from an unnamed set of 13 “smart dev-type people” about their preferences for a soft fork activation mechanism to use with taproot. Compared to earlier abuse-prevention solutions, it means any valid taproot transaction can be included in a block regardless of how many sigops it contains-keeping miner transaction code simple and fast. Investors can gain immediate liquidity and high ROI as passive income from their BEP-20 token development to increase their business growth. Many traders lost high amounts of cryptocurrencies due to phishing attacks, which are simply fake URLs that pretend to be the original website, but all they do is collect the user’s login details and send them to the attackers. To create a coinjoin, takers contact several makers, collect their input and output information, and create the transaction template.

955 updates BIP174 to standardize supplying hash preimages in PSBT input records. The standardization of these preimage fields was found to be necessary for miniscript-aware finalizers, though they can be used by any PSBT finalizer needing to satisfy hash preimage challenges (e.g. for onchain LN commitment transactions). With this change, it becomes possible to fee bump commitment transactions that may have been signed days or weeks earlier, when the current feerates would’ve been hard to predict. Various degrees of support for anchor outputs have already been merged into several LN implementations. Spontaneous payments help in cases where users just want to do ad hoc payment tracking, for example you initiate a 10 mBTC withdrawal from an exchange and either 10 mBTC shows up in your balance within a few moments or you contact support. 688 adds support for anchor https://coin-viewer.com/ outputs to the LN specification. 808 adds a warning that nodes must not release their own HTLC preimages unless they’re the final receiver of a payment. 4168 adds the ability for a plugin to specify that a hook be run before or after that of another plugin.
