Nervos CKB Development Update #5

Covering Feb 11 to Feb 24

This post is co-authored by Ian Yang, Xuejie Xiao, Qian Linfeng and James Chen.

TL;DR

• CKB VM Baseline JIT is ready for review.
• Proposal Occupied capacity increment ratehas been rejected.

Changes in RFCs

• Proposal Occupied capacity increment ratehas been rejected. We prefer to limit the capacity increment via block size and cycles limit indirectly.

Changes in CKB

CKB v0.6.0 has just released. We found some bugs in this version and have rewrote JSONRPC HTTP server (6cca12d) because of locking issues.

This version also contains a performance refactoring that transaction verification result is cached (1aa6788).

The team had been implementing get block template (#165) and CFB encoding (#144), and will send pull requests in the following weeks.
