Error on getting signedTransaction in custom chain

[sifnoc]

In a private chain for testing. the coordinator cannot get a signed transaction, proposes a large size block using the method 'web3.eth.accounts.signTransaction' on web3js v1.2.11

the reason is that the signTransaction method is using ethereumjs v2.1.2, which rejects less than the minimum amount of gas, baseFee on the ethereumjs-tx, before signing it. but, we are using the estimating gas getting from the ethereum client directly. I believe that it is more accurate than.

I think it is better using @ethereumjs/tx instead of web3.eth.account.signTransaction in contracts/tx-utils.

[chancehudson]

I think it's worth a try. @ethereumjs/tx is a major version ahead of ethereumjs-tx, it might have fixed transaction gas estimation.

In the meantime I did this to allow the coordinator to propose big blocks 0b88ce9 😅

Found another obstacle for submitting a big block #343

the coordinator could not send a propose transaction over 200 zktx included, then keep trying.
