<br> This week’s newsletter includes the final entry in our limited weekly series about mempool policy, plus our regular sections describing notable changes to clients, services, and popular Bitcoin infrastructure software. This week’s newsletter celebrates the lock-in of the taproot soft fork, describes a draft BIP for improving transaction privacy by varying the fields used to implement anti fee sniping, and features an article about the challenges of combining transaction replacement with payment batching. Anti fee sniping is a technique some wallets implement to discourage miners from trying to steal fees from each other in a way that would reduce the amount of proof of work expended on securing Bitcoin and limit users’ ability to rely on confirmation scores. For users and organizations who have a fixed maximum price they’re willing to pay in fees per transaction, using segwit could significantly reduce confirmation time for their transactions during periods of high activity. ● LND 0.13.0-beta.rc5 is a release candidate that adds support for using a pruned Bitcoin full node, allows receiving and sending payments using Atomic MultiPath (AMP), and increases its PSBT capabilities, among other improvements and bug fixes. ● HWI 2.0.2 is a minor release that adds support for message signing with the BitBox02, always uses h instead of ‘ to indicated BIP32 paths with hardened derivation, and includes several bu<br>x<br>
● Rust-Lightning 0.0.98 is a minor release containing several improvements and bug fixes. ● Rust Bitcoin 0.26.2 is the project’s latest minor release. ● Candidate Set Based (CSB) block template construction: Mark Erhardt posted to the Bitcoin-Dev mailing list about an analysis he and Clara Shikhelman performed on an alternative transaction selection algorithm for miners. ● Sparrow 1.4.0 released: Sparrow 1.4.0 adds the ability to create a child pays for parent (CPFP) transaction from the transaction list screen, user-defined fee amounts during coin selection, and various other improvements. This wouldn’t be any more effective at preventing fee sniping, but it would provide a good reason for regular wallets to set their nSequence values to the same values that are required for transactions in certain multisignature-based contract protocols, such as ideas for coinswaps and taproot-enabled LN. For more information on compensation for services, see Publication 525, Taxable and Nontaxable Income. QR codes are simply machine-readable labels via optical scanning which contains information about just about anything you want. Compared to the previous major version, it contains a several API improveme<br>a<br>bug fixes.
● Help test LND 0.9.0-beta-rc1: this pre-release of the next major version of LND brings several new features and bug fixes. By contrast, the default coin selection algorithm in LND spends higher value UTXOs before lower value UTXOs; this minimizes fees in the short term but may result in needing to pay higher fees in the future when all inputs near the size of a transaction, or larger, have already been spent. LN closing transactions to be able to pay any segwit script version, including script types that don’t yet have consensus meaning on the network, such as addresses for taproot. So we really don’t do that. One commentator points out that the use of BIP69 has so far caused three separate problems that may have led to accidental channel closures and small amounts of funds lost to unnecessary onchain fees. 872 updates BOLT3’s use of BIP69 to specify in more detail the sort order to use for commitment transaction inputs and outputs. The authors tested their algorithm on historic mempool data and found that it would’ve collected slightly more fees than Bitcoin Core’s existing algorithm in <br>s<br>ll recent blocks.
● Sparrow Wallet adds payment batching and payjoin: Sparrow’s recent 0.9.6 and 0.9.7 releases added payment batching and payjoin capabilities respectively. Replace By Fee (RBF, BIP125) and batching are two important tools for any enterprises directly interacting with Bitcoin’s mempool. That would be an improvement over the current case where each user’s CPFP fee bump is considered independently and multiple related fee bumps may not have an aggregate effect on whether an ancestor transaction is mined. Similarly, you pay the current rate of Bitcoin. Some sellers will negotiate the general price before the meeting, while some will only sell Bitcoins at the precise BTC rate established during the trade. It is important to remember that price predictions often turn out to be wrong and that prices can go down as well as up. 19866. Users that build Bitcoin Core with eBPF tracing enabled can hook into the tracepoints with the provided example scripts or write their own tracing scripts for greater observability into the node when a new block is connected, inbound P2P messages are received, Coin-viewer.com and <br>ound P2P messages are sent.
