Welcome to the second installment of eth2 fast replace.
tldr;
- Spec launch of v0.9.0 — Tonkatsu to make sure Part 0 improvement can proceed unimpeded.
- Work continues in ironing out the main points of the modified Part 1 proposal.
- Quiet consumer improvement centered on eth1 -> eth2 infrastructure, basic hardening for manufacturing, and optimizations.
Tonkatsu Launch
As promised on the most recent eth2 call, we pushed issues ahead to launch v0.9.0 release — Tonkatsu. This launch is basically simplifying with respect to Part 0. The objective right here is to take away any parts of Part 0 which might be opinionated about Part 1 to make sure Part 0 improvement 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 definitely 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 lead to a significantly 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 overall shard depend to begin have to 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 client 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 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 on account of excessive shard depend, then there could not probably 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 offers the system with better than 1 MB/s of information availability which synergizes properly with promising L2 schemes corresponding to ZKRollup and OVM. The community security of those bigger shard block sizes are justified by recent experimental research accomplished 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 main points of this new proposal. For extra particulars, take a look at the work-in-progress PR or a few of the Phase 1 issues.
Quiet, yet efficient consumer improvement
Eth2 shoppers proceed to quietly develop. As mentioned on the most recent 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 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 cross the brand new take a look at vectors and are introducing the simple attestation aggregation strategy.
