Welcome to the second installment of eth2 fast replace.
tldr;
- Spec launch of v0.9.0 — Tonkatsu to make sure Section 0 growth can proceed unimpeded.
- Work continues in ironing out the small print of the modified Section 1 proposal.
- Quiet consumer growth centered on eth1 -> eth2 infrastructure, normal 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 essentially simplifying with respect to Section 0. The objective right here is to take away any parts of Section 0 which are opinionated about Section 1 to make sure Section 0 growth can proceed unimpeded whatever the work-in-progress modified sharding proposal.

Ongoing Section 1 Redesign
As talked about within the final eth2 quick update, we’re virtually actually taking a brand new and less complicated path for Section 1. The new sharding proposal facilitates “crosslinks” for all shards at every slot. This drastically simplifies communication between shards and can lead to a a lot better and less complicated developer/consumer expertise come Section 2.
Earlier cross-shard communication (approximate)
New shard design proposal
To help this new proposal, the whole shard rely to begin have to be diminished 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 assets accessible to client laptops will increase. The next are the first causes for the requisite discount in whole shards:
- Every shard induces an attestation load on the community and beacon chain at every slot relatively than at every epoch
- Every committee have to be of a minimum safe variety of validators. If there are too many committees per epoch attributable to 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 attain the same scalability because the earlier proposal, goal shard block sizes are being elevated 8x, from 16kB to 128kB. This gives the system with higher than 1 MB/s of information availability which synergizes properly with promising L2 schemes reminiscent of ZKRollup and OVM. The community security of those bigger shard block sizes are justified by recent experimental research completed on the prevailing Ethereum community.
A lot of the EF analysis workforce’s focus previously 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 few of the Phase 1 issues.
Quiet, yet efficient consumer 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 consumer 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.
