It has been possible to run Bitcoin Core as a background daemon process since early versions by starting the program with the -daemon configuration option. 17920 adds support for using GNU Guix to reproducibly build Bitcoin Core binaries for macOS. Windows and several Linux platforms were already supported, so the new Guix deterministic build system now supports all the same platforms as the existing Gitian system. ● Blockstream Satellite 2.0 supports initial block download: Blockstream outlines version 2.0 upgrades to their satellite service which include expanded Asia-Pacific coverage, additional bandwidth, and an updated protocol that enables a full node to complete an initial sync using only the satellite feed. User Pseudonymous explains that while BIP37 bloom transaction filtering supports unconfirmed transactions, compact block filters have no such consideration and only service light clients with condensed block data since light clients have no way of verifying that unconfirmed transactions are valid. The tree graph is a particular graph that runs from top to bottom: At the top is the node from which the graph starts, while scrolling gradually from top to bottom we find the different nodes.

Additionally, the remote node may not automatically see the funding transaction and so may not be able to help the funder get their money back. This week’s newsletter describes a discussion about rescuing lost LN funding transactions and includes our regular sections with announcements of releases, release candidates, and notable changes to popular Bitcoin infrastructure software. Pieter Wuille describes a variety of nuanced considerations and incentives surrounding transaction propagation on the network concluding that no type of unconfirmed transaction can be trusted and users should wait for confirmations. This week’s newsletter describes a proposal for using fidelity bonds on LN to prevent denial of service attacks, summarizes a PR to address a fee siphoning attack that could affect LN channels using anchor outputs, and links to a proposed specification for miniscript. ● Would first-seen prevent a double spend attack? ● Joinmarket has two types of users: those who pay to coinjoin (market takers) and those who are paid for allowing their UTXOs to be used (market makers). LND previously checked this by looking for the WitnessUtxo field in the PSBT, but this field is technically optional for segwit UTXOs and so some PSBT creators don’t provide it.

LN requires segwit UTXOs in order to prevent txid malleability from making refund transactions unspendable. 5291 improves the way LND ensures that PSBTs for funding transactions only spend segwit UTXOs. UTXOs created by other users in the transaction. ● Bitcoin Core Usage Survey: Bitcoin Core developer Andrew Chow created a survey for users of Bitcoin Core. Notable improvements include a more featureful and visually appealing wallet setup wizard, the ability to import wallets created using Specter, and more efficient QR codes for bech32 addresses. ● Bitcoin Core 0.21.0rc2 is a release candidate for the next major version of this full node implementation and its associated wallet and other software. 20981 has been opened to explore potential use cases for USDT probes in Bitcoin Core now that the framework has been merged. 19866 adds a framework for User-Level Statically Defined Trace (USDT) probes. 5253 adds support for Atomic Multipath Payment (AMP) invoices across high-level LND RPC commands such as SendPayment, AddInvoice, and SubscribeInvoice. The patch requires adding payment secrets to the invoices that LND produces. ● LND 0.12.0-beta is the latest release for the next major version of this LN software.

● BTCPay Server 1.0.7.0 is the latest release for this self-hosted payment processing software. Until the payment eventually times out, each channel used to route the payment is unable to use those funds to route other user’s payments. 5274 limits the maximum amount of funds the node reserves to allow CPFP fee bumping for anchor outputs to ten times the per-channel amount. One way to lower your trading fee is to keep some Binance Coin in your account at all times so your fees can be taken from that. In a follow up to the original 2015 question, Steven Roose provides a one line bitcoin-cli command using getrawtransaction against a full node to generate a PDF of the Bitcoin whitepaper. To achieve this, it had to make certain trade-offs - one being that it wasn’t as flexible from a programmability standpoint as other blockchains. If you change this, the time represented in the candlestick will change.
