The case for deferring BIP54's coinbase nLockTime rule

A position piece. It argues one side — that this particular rule is premature and that cheaper, nLockTime-preserving alternatives exist — and backs the empirical claims against the historical record and recent mainnet data.

BIP54 ("Consensus Cleanup") bundles four soft-fork fixes. Three are uncontroversial — the timewarp fix, the 64-byte-transaction ban, and a per-transaction sigop limit. The fourth is contested: it requires every coinbase transaction's nLockTime to equal block_height − 1 (with nSequence ≠ 0xffffffff, so the locktime is actually enforced). This is the case for leaving that

Rationale for the Covenants Support Wiki Page

Intro

This document is the result of many conversations with many bitcoin devs over the last several years. My positions on these topics are constantly evolving as I learn more information. Since, up till now, I am not a bitcoin core contributor, my review of the actual code has been rather sparse and I am mostly relying on the opinions of others to inform my views as to the technical soundness of the actual implementations. Thus, this document takes a more high-level, "Concept ACK/Concept NACK" approach than an "ACK/NACK" one.

Reasons we must update bitcoin:

• payments and custody centralizing
• blocks are too small for all the coffees, Lightning is hard to use (for various reasons)

Installing nix-bitcoin on a OnePlus 6 (enchilada)

Build the image

(See the README for up-to-date instructions)

git clone https://github.com/chrisguida/mobile-nixos-oneplus-enchilada-template -b cguida/nix-bitcoin
cd mobile-nixos-oneplus-enchilada-template

Installing NixOS on a Raspberry Pi 4B with an SSD as the boot drive

You will need:

• A Pi 4B
• A USB-C power supply (probably the official one)
• An ethernet cable
• A microsd card
• An SSD, I used the Samsung T7 2TB
• A powered USB hub (THIS IS ABSOLUTELY REQUIRED OR YOU WILL HAVE TOTALLY UNPREDICTABLE FAILURES AND CORRUPTION)

The following is one way to broadcast an LN-symmetry (formerly eltoo) settlement tx on inquisition signet, using instagibbs' original APO eltoo implementation on CLN.

1. build and install inquisition signet, you will need this fork of bitcoind for support of APO, ephemeral anchors, and taproot annex blobs

git clone https://github.com/bitcoin-inquisition/bitcoin
cd bitcoin
./autogen.sh
./configure
make -j$(( $(nproc) - 1))
sudo make install

Notes for installing Core Lightning on MacOS M1 (tested on M1 Max)

Follow MacOS install guide

Keep in mind that the instructions are designed for Intel, so /usr/local needs to be replaced by /opt/homebrew in most places.

Make sure native rust toolchain is installed for rust stuff

install nightly-aarch64-apple-darwin toolchain to get rid of errors about wrong arch lib linked
