I really like your project. Do you plan to list it on any exchanges?

the project doesn't pursue exchange listings. exchange listings will come if participants see fit. atomic swaps via HTLCs are the protocol-native primitive for peer-to-peer trading

v1.10.0 is out. fixes the IBD sync stalls and false-positive peer bans several users hit on v1.8.x–v1.9.x. v1.9.2 addressed one path; v1.10.0 covers the rest

root cause: the peer-strike subsystem was treating honest peer behaviour (rate-limited replies, at-tip tip-polling, transient transport hiccups) the same as protocol violations. honest peers accumulated strikes and got identity-banned. once enough were banned, IBD couldn't find a working sync source

if your node's been stalling, or you accumulated bans from an earlier version, start v1.10.0 once with `--purge-bans`. it wipes the persisted IP and identity ban tables on startup, then the node runs normally. don't leave the flag set in subsequent starts

wire-compatible with all previous versions. no protocol bump, no consensus changes — block/tx/chain validation rules are byte-identical. upgrade at your convenience if you're syncing fine

v1.10.1 — IBD reliability fix. closes a stall where a syncing node could get permanently stuck below tip if it lost its sync peer mid-download, even after that peer reconnected

drop-in upgrade for healthy nodes. if your node's already wedged below tip, recovery is a fresh-datadir cold-boot on v1.10.1

no project-operated or project-endorsed exchange. peer-to-peer trade is up to you and your counterparty

the protocol-native primitive for trust-minimized swaps is htlc atomic swaps (§22.5 of the spec at https://exfer.org). that lets you and a counterparty exchange across chains without either side trusting the other to complete the trade

v1.10.2 — node startup replay is now ~100× faster below the assume-valid checkpoint. pre-checkpoint replay drops from minutes (or hours on network-attached storage) to seconds (or minutes). signatures on already-validated historical blocks no longer get re-verified on every restart; duplicate disk writes during replay are gone. from pr #3 by https://github.com/exfer-stack

the speedup is on startup replay specifically, not on initial sync of a new node. existing fully-synced nodes restarting get the big win; fresh cold-boot from genesis is still network-bound during ibd. already-running at-tip nodes see no change until next restart

per-block state-root check still runs on every replayed block — if the fast path ever misapplied a block, the node aborts with state root mismatch rather than silently accepting bad state. live block validation unchanged

v1.10.3 — exfer-stack's checkpoint-bump pr is in. ASSUME_VALID_HEIGHT moves from 302,400 to 500,000. combined with v1.10.2's fast path, an additional ~200k historical blocks now replay near-instantly during fresh cold-boot. from pr by https://github.com/exfer-stack

scope: cold-boot/replay speedup, not a live-validation change. nodes already at tip see no change until next restart, and even then the difference is only on the additional 200k-block range. fresh new nodes joining the network get the full benefit

also adds tools/regen_assume_valid.py so future checkpoint bumps are mechanised rather than ad-hoc. per-block state-root cross-check still runs on every replayed block; --no-assume-valid / --verify-all opt out of the fast path as before

this project will soon be forgotten, sorry

v1.11.0 — exfer-stack's phase 3a pr is in. node startup now uses a persisted utxo snapshot instead of replaying the chain on every restart. first boot after upgrade does a one-time lazy migration (slow, don't interrupt); every restart after that is fast

scope: the absolute speedup on the current chain is small because per-block cost is dominated by smt updates rather than tx validation. the bigger story is structural — restart cost is now decoupled from chain activity, with crash-safe markers and an architecture that leaves clean runway for further optimisation

new flags: `--no-auto-migrate` to skip the migration (replay-every-boot until you opt in), `--rebuild-state` for recovery if you ever hit a snapshot-corruption error. drop-in upgrade otherwise — swap the binary, restart, let the first boot finish
