A pristine JavaScript Bitcoin kernel and the layers it power — one consensus engine, deployed from full node to browser, with no premine, no trusted set, and no shortcuts. Everything here re-derives Bitcoin's truth from the rules, never trusting a server or a federation.
A monorepo of independently-importable packages (npm workspaces, bundler-free
ESM). Each package is a clean library with its own package.json, so any one can
graduate to its own repo or npm publish later without disruption.
packages/
kernel/ consensus engine — block/script/sighash/UTXO validation (folds in from the engine repo)
web/ a Bitcoin node in the browser — block cache, txid index,
source registry (cache/peer/explorer), WebRTC peer mesh,
in-window DAG verification
headers/ headers-only verification (planned)
spv/ SPV / merkle-proof client (planned)
utreexo/ compact UTXO-set accumulator — full validation, ~KB state (planned)
swiftsync/ stateless, parallel fast initial validation (planned)
wallet/ wallet library (planned)
Apps and demos live in their own repos (each a deployable gh-pages site with its own domain), importing these packages — not in this monorepo.
The default branch is gh-pages, and packages are served as static ESM — no
bundler, no npm copy step. A demo imports a library directly by URL:
// rolling latest (gh-pages tip)import{Mesh}from'https://bitcoin-kernel.com/kernel/packages/web/mesh.js';// pinned to a tag/commit for a reproducible deploy (via jsDelivr)import{Mesh}from'https://cdn.jsdelivr.net/gh/bitcoin-kernel/kernel@v0.0.1/packages/web/mesh.js';(The bitcoin-kernel.github.io/kernel/ Pages URL redirects to the
bitcoin-kernel.com/kernel/ custom domain.)
