Motivation:

We want to refactor the table calculator so that devs only have to worry about doing 1 thing: calculating weights of the operator. Everything else should be handled by a base contract

Modifications:

  • Create BN254TableCalculatorBase, an abstract contract that has all methods implemented, except _getOperatorWeights
  • BN254TableCalculator now inherits from BN254TableCalculatorBase and implements simple addition of operator stakes
  • Add unit tests for BN254TableCalculatorBase and a tree file
  • Resizes arrays for operators who have no slashable stake or are not registered in the KeyRegistrar

Result:

Cleaner abstraction

Should we maybe "effectively" resize this array? As it stands operatorInfoLeaves will potentially have blank entries if operators aren't registered

Registration checked in the get operator weights function

Nvm. Also beed to adjust number of operators

**Motivation:**

For the aggregator, we need to provide a block.number that is associated
with a reference timestamp to easily index stake weights.

**Modifications:**

Add a `referenceBlockNumber` to `confirmGlobalTableRoot` along with the
following functions:
- `getLatestReferenceBlockNumber`
- `getReferenceBlockNumber(timestamp)`

**Result:**

Easier offchain usage

# v1.7.0 Multi Chain

The multichain release enables AVSs to launch their services and make
verified Operator outputs available on any EVM chain, meeting their
customers where they are. AVSs can specify custom operator weights to be
transported to any destination chain. The release has 3 components:

1. Core Contracts
2. AVS Contracts
3. Offchain Infrastructure

The below release notes cover Core Contracts. For more information on
the end to end protocol, see our [docs](../docs/multichain/README.md)
and
[ELIP-008](https://github.com/eigenfoundation/ELIPs/blob/main/ELIPs/ELIP-008.md).

## Release Manager

@ypatil12 @eigenmikem

## Highlights

This multichain release only introduces new standards and contracts. As
a result, there are no breaking changes or deprecations.

🚀 New Features

Source Chain Contracts
- `KeyRegistrar`: Manages cryptographic keys for operators across
different operator sets. It supports both ECDSA and BN254 key types and
ensures global uniqueness of keys across all operator sets
- `CrossChainRegistry`: Enables AVSs to register to have their operator
stakes transported to supported destination chains
- `ReleaseManager`: Provides a standardized way for AVSs to publish
software artifacts (binaries, docker images, etc.) that operators in
their operator sets should upgrade to by specified deadlines

Destination Chain Contracts
- `CertificateVerifier`: Proves the offchain execution of a task, via a
Certificate, by the operators of an operatorSet. Two types of key
material are supported: ECDSA and BN254
- `OperatorTableUpdater`: Updates operator tables in the
`CertificateVerifier` to have tasks validated against up-to-date
operator stake weights

🔧 Improvements – Enhancements to existing features.

- The multichain protocol has protocol-ized several AVS-deployed
contracts, enabling an simpler AVS developer experience. These include:
- `KeyRegistrar`: Manages BLS and ECDSA signing keys. AVSs no longer
have to deploy a `BLSAPKRegistry`
- `CertificateVerifier`: Handles signature verification for BLS and
ECDSA keys. AVSs no longer have to deploy a `BLSSignatureChecker`
- Offchain Multichain Transport: AVSs no longer have to maintain
[avs-sync](https://github.com/Layr-Labs/avs-sync) to keep operator
stakes fresh
