Layr-Labs/eigenda v2.1.0-rc.3

[Testnet] EigenDA v2.1.0-rc.3

on GitHub

This release is optional but highly recommended for operators because it resolves a goroutine leak. It is optional for users.

This release follows the Blazar release (0.9.2), colloquially referred to as "v2". We opted to bump the semver to 2.1.0 to match this v2 name and remove some confusion we have observed both internally and externally.

In order to keep our releases simpler for now, we opt to release all services of the monorepo together, following a single semver. We cannot for this reason commit to strictly following semver practices, and reserve the right to push breaking changes to auxiliary services such as the dataapi.

We are deprecating the [eigenda-proxy repo](https://github.com/Layr-Labs/eigenda-proxy, and have moved its codebase under api/proxy. Monorepo releases will include proxy code moving forward.

Monorepo-wide changes

One important change is that we deployed an EigenDADirectory contract to all chains, which should be used as the main contract address locator. See our docs network pages for more information.

• chore: bump to go1.24 by @samlaf in #1669
• chore: upgrade gnark-crypto 0.16->0.18 by @samlaf in #1755
• feat: eth client address directory by @hopeyen in #1691
• feat: Implement claude log preprocessing command by @litt3 in #1692

Validator Node

Fixes a goroutine leak that leads to CPU starvation over long time periods.

This release also adds a new flag NODE_EIGENDA_DIRECTORY which takes advantaged of the newly deployed contract directory. In a future release we will be deprecating the NODE_BLS_OPERATOR_STATE_RETRIVER and NODE_EIGENDA_SERVICE_MANAGER in favor of NODE_EIGENDA_DIRECTORY.

Contracts

The EigenDADirectory contract was added and deployed to all networks, and should going forward be used as the single source of truth for all EigenDA contract addresses.

• feat(contracts): Immutable threshold registry for EigenDAV1 cert verifier by @ethenotethan in #1658
• feat: add address directory by @pakim249CAL in #1676
• feat: enumerable names and script configs for address registry by @pakim249CAL in #1697
• feat(contracts): new DeployEigenDA script (used to deploy mainnet beta) #1675 by @pakim249CAL #1675

Integrations (contracts, clients, proxy)

This release introduces the CertVerifierV3 as well as the CertVerifierRouter which allows for secure upgrades to verification logic. See our custom security docs for more information. Take a look at our updated secure integration spec page for our latest thinking.

The proxy --network-id flag now supports mainnet, and we also added a .env.exampleV2.mainnet example env file.

We reverted the NTP clock in the client, as we felt its implementation was not ideal, and we also believe clock control should be left to the controlling environment. Please make sure that the computer you are running proxy and/or clients on has a synchronized clock.
