An update to the devnet to introduce a local heimdall to facilitate multiple validators without the need for an external process, and hence validator registration/staking etc. In this initial release only span generation is supported. It has the following changes: * Introduction of a local grpc heimdall interface * Allocation of accounts via a devnet account generator () * Introduction on 'Services' for the network config "--chain bor-devnet --bor.localheimdall" will run a 2 validator network with a local service "--chain bor-devnet --bor.withoutheimdall" will sun a single validator with no heimdall service as before --------- Co-authored-by: Alex Sharp <alexsharp@Alexs-MacBook-Pro-2.local>
