Development Update — March 17

Happy Birthday, Skycoin Blockchain

Eleven years ago today — March 17, 2015 — the Skycoin genesis block was created. The chain has been running continuously ever since, through organizational splits, team changes, and complete codebase rewrites. Block 194,634 and counting.

Skycoin: Web Wallet Hardening

A dense day of web wallet improvements:

BIP44 account support — the desktop wallet (skycoin-web) now properly supports BIP44 multi-account structure with encrypted seed storage. The beforeunload handler was fixed to prevent accidental data loss.

Hardware wallet support — Skywallet integration was added to skycoin-web, enabling transaction signing with hardware wallet devices directly from the thin client interface.

Request chunking — GET requests for balance and outputs are now chunked to avoid URI length limits when querying many addresses. Read-only POST requests are forwarded as POST instead of being converted to GET, which was causing failures with large address sets.

Wallet encryption UI — server-managed wallets can now be encrypted and decrypted from the UI.

Lint and test fixes — golangci-lint v2.6.1 errcheck and gosec errors were fixed across the codebase. WASM binaries were rebuilt. BIP44 integration test golden files were updated with the new accounts field.

Skywire: Bandwidth-Based Rewards

The transition to bandwidth-based rewards landed in PR #2221 — one of the largest PRs in Skywire’s recent history at nearly 10,000 lines changed across 80 files.

Two-pool reward model — Pool 1 distributes equally to all uptime-eligible visors. Pool 2 distributes proportionally based on bandwidth. Both are additive per visor.

bw-collect subcommand — fetches per-transport bandwidth from the TPD, filters out same-LAN transports using survey IP data, and writes daily bandwidth stats. Designed to run hourly via systemd.

Accept loop fixes — the same accept-loop-dying-on-transient-error pattern found in DMSG yesterday was found and fixed across seven more Skywire components: STCPR transport, VPN server, sky ping, sky forwarding, latency probe, raw TCP forwarding, and the app process manager.

Panic fixes — bounds checks added for VPN/proxy client address parsing, nil dereference guards for DMSG client summary, off-by-one fix in public visor slice bounds, and a logic error fix in bandwidth stats (|| should have been &&).

DMSG: Shutdown Logging Fix

The dmsgctrl shutdown was producing noisy log spam on clean exits (#346). Fixed by checking for context cancellation before logging errors.
