Week in Ethereum
News and Links
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
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
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.
