  • TCP + WS listening mode by default for all upgraded nodes enabled: feat: let old config node open ws listen by default #4741
  • CKB listen on the WS port is now by default: feat: default listen on ws port #4729
    • Finished development of the light client with wasm support feat: wasm support for browser ckb-light-client#204. Now under testing.

• Fiber Network

  The first version of Fiber Network with backward compatible is set for release by the end of this month. We’re currently testing and fixing.

  • Finished the audit of Fiber contract.
  • A fix for Musig2VerifyError issues via Rewrite channel actor state tlc operations fiber#341
  • Onion encryption Setup onion error packet fiber#354 for improved privacy in error handling.
  • Type safe onion packet feat: use type safe onion packet fiber#358

• CKB-VM

  • Added more tests and fuzz testing for ckb-fixed-solution, and identified an upstream issue fix: make panic free in transcendental.rs encointer/substrate-fixed#21. This could simplify DeFi development on CKB.
  • Ongoing work on contract maintenance process
  • Investigated solutions for On-chain Scripts Providing Off-chain Services
  • Implemented a BLAKE2 cryptographic hash and testing on https://github.com/mohanson/blake2ya
  • nervosnetwork/ckb-vm@abe964e

Fixes

  • bugfix: add missing crate features #4736
  • fix: bug on unsupported protocol tentacle#388
  • Remove anyhow's backtrace from RPC response #4728
• Fiber Network
  • Fix channel balance issue caused by remove tlc failure fiber#368
  • chore: add config doc fiber#384
  • Fix onion hop length limit issue fiber#383
  • Fix path find fee rate issue from source node fiber#382
  • Fix send payment fee overflow issue fiber#380
  • chore: cleanup unsed code in migration fiber#378
  • cleanup AddTlcCommand fiber#365
  • Fix channel state issue in RPC fiber#350

In Pipeline…

• CKB
  • [WIP] Add proxy support for ckb #4733
  • use last_common as start in BlockFetcher #4723
  • Extend the hardcoded assume_valid_target to an array. #4742
  • Investigating solutions for CKB Database Multi-Version Management
  • Progressing well with plans for reproducible builds for CKB
  • Ongoing work on Freezer: repair and partial rewrite
  • Partial pruning of historical data: under certain security assumptions, the "download-and-upload-simultaneously" model could potentially be applied to blockchains as well. For instance, this could be feasible when using assumevalid, where certain checkpoints are pre-defined as trusted.
  • More rigorous CKB on Wasm is incoming
    • sql.js bind process initially runs smoothly https://github.com/driftluo/sqlite-web
• Fiber Network
  • A more robust gossip message protocol is coming. Refactor gossip protocol fiber#308
  • Exclude used Cells during concurrent funding requests: Cells exclusion for active funding tx negotiation fiber#74
  • Save shared secret for forwarding the onion packet, and use it to encrypt the backwarding error packets. Onion error encryption fiber#356
  • Limit the size of remote_commitment_points and remote_nonces Fix tlc space issue caused by remote_nonces and remote_commitment_points fiber#374
