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 targeted on eth1 -> eth2 infrastructure, basic hardening for manufacturing, and optimizations.
Tonkatsu Launch
As promised on the most recent eth2 name, we pushed issues ahead to launch v0.9.0 launch — Tonkatsu. This launch is essentially 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 fast replace, we’re virtually definitely taking a brand new and easier path 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 help this new proposal, the whole shard depend to begin should 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 commonplace assets out there 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 relatively than at every epoch
- Every committee should be of a minimal secure variety of validators. If there are too many committees per epoch attributable to 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 attain the same scalability because the earlier proposal, goal shard block sizes are being elevated 8x, from 16kB to 128kB. This supplies the system with better than 1 MB/s of knowledge availability which synergizes properly with promising L2 schemes akin to ZKRollup and OVM. The community security of those bigger shard block sizes are justified by current experimental analysis accomplished on the present Ethereum community.
A lot of the EF analysis workforce’s focus prior to now 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 among the Part 1 points.
Quiet, yet efficient consumer improvement
Eth2 purchasers proceed to quietly develop. As mentioned on the most recent eth2 name, effort is being put into dealing with deposits from eth1, usually hardening purchasers 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, purchasers are updating their state transition logic to go the brand new take a look at vectors and are introducing the easy attestation aggregation technique.
