To achieve the above requires us to optimize resource consumption in novel ways. At the execution layer, we aim to offer a unique combination of lower space usage and faster sync.
Our method of syncing, which we call beam-ish sync, will allow nodes to participate in the network early, while data sync continues in the background - this behaviour is similar to Fluffy (our Portal Network light client) and our work there will be re-used here - the idea is that we'll eventually integrate Fluffy into our execution client.
In addition to integating Fluffy, one of our main design goals is to make it as easy as possible for our consensus and execution clients to be bundled into a single piece of software; this will drastically improve the UX of running a post-merge client, making it very similar to running a pre-merge PoW client today.
This ties into our overarching vision: to significantly lower the barrier to running both full nodes and light clients, and in doing so help make Ethereum as accessible and decentralised as possible.
Renewed funding from the EF to accelerate development
Completed Berlin and London fork compatibility (EIP-1559): we now pass nearly all the EF Hive testsuite, and 100% of contract execution tests (47,951 tests)
New GraphQL and WebSocket APIs, complementing JSON-RPC
EVMC compatibility, supporting third-party optimised EVM plugins. Up to 100x memory saving during contract executions. Asynchronous EVM to execute many contracts in parallel (while they wait for data from the network)
Proof-of-authority validation for the Goerli test network. Updated network protocols, to work with the latest eth/65-66 and snap/1 protocols
A prototype new mechanism for state sync which combines what have been called Fast sync, Snap sync and Beam sync in a self-tuning way, and allows the user to participate in the network (read accounts, run transactions etc.) while sync is still in progress
The plan for this month is to participate in the rolling merge devnets - one per week - before the more persistent testnet planned for the first week of December. We are working as hard as we can to try to have our execution layer client ready in time. Our immediate goal however is to pass the merge interop milestones in local tests.
