[ANN] Exfer — A Peer-to-Peer Settlement Protocol for Autonomous Machines

[ahuman_exfer]

v1.12.0 — exfer-stack's server-push pr is in. wallets now update instantly. a node nudges a watching wallet the moment a watched address's balance changes — incoming or outgoing — so the wallet renders the update at network speed instead of waiting on a poll (previously ~4–18s)

new push endpoint: GET /sse on the rpc port, per-address subscribe, default on. opt out with --rpc-sse-enabled false. note that a persistent subscription channel discloses which addresses a subscriber is watching to the node operator — opt out if that's a concern

the user-visible effect needs both sides current: a v1.12.0 node serving a v1.12.0-aware wallet (walletd / desktop / mobile). public-node operators upgrading is what lights up wallets across the network

also in the release for builders: get_address_mempool_batch, covenants::htlc observer types, and script::structural_merkle_hash for template-identity comparisons

additive only — no consensus or p2p changes, no datadir migration. drop in the binary, restart

Interesting project. Seems like this trend is inevitable and will continue. The next phase in crypto is here.

v1.13.0 — orphan-rate fix and reliability hardening, validated by a ~6-day mainnet soak

root cause: honest peers were getting disconnected and their blocks re-counted as orphans (~13/day). that's closed. across the full soak window the orphan rate sat at the natural tip-collision floor (under 0.6%), reorg errors and rate-cap disconnects and live-lock triggers all zero across ~290 clean reorgs, and the fleet held a single tip the entire time

self-mined block accept latency: ~5,200ms → ~21ms (~247× faster). single biggest measurable change

also in this release:

get_node_info metrics endpoint — operators can watch their own node (orphans, reorgs, peers, tip) without grepping logs
bech32m checksummed addresses — catches transposition typos the old raw-hex form couldn't. accepted everywhere; existing addresses keep working
datum-carrying wallet sends — quote-bound settlement now works from the base cli
a persistent public testnet with real low-difficulty pow — a place to try things without mainnet stakes

drop-in upgrade. mainnet consensus is byte-for-byte unchanged — no fork, no flag day. old and new nodes interoperate
