Welcome to the second installment of eth2 fast replace.
tldr;
- Spec launch of v0.9.0 — Tonkatsu to make sure Part 0 growth can proceed unimpeded.
- Work continues in ironing out the small print of the modified Part 1 proposal.
- Quiet shopper growth centered on eth1 -> eth2 infrastructure, basic hardening for manufacturing, and optimizations.
Tonkatsu Launch
As promised on the newest eth2 call, we pushed issues ahead to launch v0.9.0 release — Tonkatsu. This launch is basically simplifying with respect to Part 0. The purpose right here is to take away any parts of Part 0 which can be opinionated about Part 1 to make sure Part 0 growth can proceed unimpeded whatever the work-in-progress modified sharding proposal.

Ongoing Part 1 Redesign
As talked about within the final eth2 quick update, we’re nearly actually taking a brand new and less complicated course for Part 1. The new sharding proposal facilitates “crosslinks” for all shards at every slot. This drastically simplifies communication between shards and can end in a a lot better and less complicated developer/person expertise come Part 2.
Earlier cross-shard communication (approximate)
New shard design proposal
To help this new proposal, the whole shard rely to start out should be decreased from 1024 to the brand new estimate of 64, with the intention to scale up the variety of shards over time (~10 years) as customary sources obtainable to shopper laptops will increase. The next are the first causes for the requisite discount in complete shards:
- Every shard induces an attestation load on the community and beacon chain at every slot reasonably than at every epoch
- Every committee should be of a minimum safe variety of validators. If there are too many committees per epoch resulting from excessive shard rely, then there could not probably be sufficient 32-ETH validators to soundly allocate sufficient to every committee
[EDIT: the following paragraph was added after initial release of the blog post in response to some discussion on reddit]
To realize an analogous scalability because the earlier proposal, goal shard block sizes are being elevated 8x, from 16kB to 128kB. This gives the system with larger than 1 MB/s of knowledge availability which synergizes nicely with promising L2 schemes akin to ZKRollup and OVM. The community security of those bigger shard block sizes are justified by recent experimental research executed on the prevailing Ethereum community.
A lot of the EF analysis crew’s focus up to now few weeks has been round vetting and ironing out the small print of this new proposal. For extra particulars, try the work-in-progress PR or a number of the Phase 1 issues.
Quiet, yet efficient shopper growth
Eth2 shoppers proceed to quietly develop. As mentioned on the newest eth2 call, effort is being put into dealing with deposits from eth1, typically hardening shoppers for manufacturing, optimization of state transition and BLS implementations, cross-client fuzzing, networking monitoring tooling, and extra! Bigger single shopper testnets are within the works in addition to continued cross-client experimentation.
Now that v0.9.0 has been launched, shoppers are updating their state transition logic to move the brand new check vectors and are introducing the simple attestation aggregation strategy.
