- Latest core dev call. Lane Rettig’s detailed notes.
- My tl;dr summary of ASIC discussion: the ASIC efficiency isn’t that great so it’s not an emergency, nor are we yet sure what would break the ASIC. Casper FFG is undergoing formal verification and should be ready in ~3 months, but could be rushed to production if necessary. It’s more or less ready to be implemented by clients.
- Hudson Jameson summarizes the facts as well as the arguments for and against forking for ASIC resistance
- Perun: virtual payment and state channel networks
- VB: A general framework of overhead and finality time in sharding, and a proposal
- More VB: A minimal sharding proposal for development now
- Justin Drake: Expanding on proposer/notary separation
- Justin Drake: serialisation scheme for blobs in collation bodies
- Offchain collation headers or off-chain intermediate blocks
- Hsiao-Wei Wang: Per period committee snapshot
- tl;dr on sharding this week: deprecated the previous phase 1 spec, research in a bit of flux, lots of new ideas.
