cdk-data-availability's Issues

Add docker image pushing to CI

Db should be moved outside DAC node

We are working on deploying CDKs and having the db as a part of the node would not work in production(maintained dbs are battle-tested).
I haven't seen any activity on this repo in a while, so I could take this up if the team finds it important.

Create abstraction for type `SignedSequenceBanana` and `SignedSequence`

This objects require a function SetSignature.
Also definition of a interface as:

type SignedInterface interface {
	SetSignature([]byte)
	Signer() (common.Address, error)
}

correction fee

olease correction fee in network and run more nodes

It is recommended to modify the findContractDeploymentBlock function to obtain the block number and call eth.HeaderByNumber.

'r' value overflows uint256 is shown when starting DA program

Then I used Delve to find the error out, and I saw this code thrown the error :

> github.com/0xPolygon/cdk-data-availability/synchronizer.findContractDeploymentBlock() ./synchronizer/init.go:51 (hits goroutine(1):1 total:1) (PC: 0x1143f63)
    46:		eth, err := ethclient.DialContext(ctx, url)
    47:		if err != nil {
    48:			return nil, err
    49:		}
    50:		latestBlock, err := eth.BlockByNumber(ctx, nil)
=>  51:		if err != nil {
    52:			return nil, err
    53:		}
    54:		firstBlock := findCode(ctx, eth, contract, 0, latestBlock.Number().Int64())
    55:		return big.NewInt(firstBlock), nil
    56:	}
(dlv) p err
error(*errors.errorString) *{
	s: "'r' value overflows uint256",}
(dlv) q

I fixed it by change 'eth.BlockByNumber' to 'eth.HeaderByNumber(ctx, nil)'

When I got the error I am using branch 'v0.0.3', but I saw the default branch is still using 'eth.BlockByNumber'

need to update the PolygonvalidiumMetaData abi

Problem

We were updating the cdk quickstart using the latest images:

when we were testing, we found L2->L1 bridging failed

Root Cause Analysis

looking into the logs, we found it's due to sequencer cannot get signature from the DAC

then we found in the DA container logs:

looking into the code, we saw

and the ABI was read from https://github.com/0xPolygon/cdk-data-availability/blob/v0.0.6/etherman/smartcontracts/polygonvalidium/polygonvalidium.go

but this file was lastly updated 2 months ago. and I found that there are indeed some diffs: https://www.diffchecker.com/OLfZGyrR/

w the latest contracts code we used: https://github.com/0xPolygonHermez/zkevm-contracts/tree/v5.0.1-rc.2-fork.8
