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 main points of the modified Part 1 proposal.
- Quiet shopper growth targeted 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 essentially 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 virtually actually taking a brand new and easier route 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 significantly better and easier developer/consumer expertise come Part 2.
Earlier cross-shard communication (approximate)
New shard design proposal
To assist this new proposal, the full shard depend to begin have to be lowered from 1024 to the brand new estimate of 64, with the intention to scale up the variety of shards over time (~10 years) as normal sources obtainable to shopper 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 quite than at every epoch
- Every committee have to be of a minimum safe variety of validators. If there are too many committees per epoch resulting from excessive shard depend, then there could not presumably be sufficient 32-ETH validators to securely 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 effectively with promising L2 schemes corresponding to ZKRollup and OVM. The community security of those bigger shard block sizes are justified by recent experimental research achieved on the present Ethereum community.
A lot of the EF analysis crew’s focus previously few weeks has been round vetting and ironing out the main points of this new proposal. For extra particulars, try the work-in-progress PR or among 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, usually 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 go the brand new check vectors and are introducing the simple attestation aggregation strategy.
