Genesis

Marker genesis is a developer utility to easy running atlas blockchain testnets and related jobs around testnets.

Its main advantage over previous solutions is that it's able to create a genesis.json where all core conctracts are already deployed in it.

We need to use the marker tool. For information on how to use the marker tool, please refer to Marker

Generating a genesis.json file

git clone github.com/mapprotocol/atlas
cd marker/config
vim markerConfig.json

First you need to config the markerConfig.json like this: set your own keys.

MarkerConfig.json params instruction

  • Address: This account address will be registered to the validator list as a validator account

  • SignerAddress: It is authorized by account address to replace the validator to make consensus with other nodes on the MAP network

  • ECDSASignature: Signeraddress ecdsasignature for account address

  • PublicKeyHex: Signeraddress`s Publickeyhex

  • BLSPubKey: Signeraddress`s Blspubkey

  • BLSG1PubKey: Signeraddress`s BLSG1PubKey

  • BLSProofOfPossession: BLS signature data of signeraddress to account address

generate signers PublicKeyHex、BLSPubKey、BLSG1PubKey` info please refer to Create four validator accounts

generate signers ECDSASignature` info please refer to make ECDSA signature from signer

generate signers BLSProofOfPossession` info please refer to make BLS proof of possession from signer

note:If you use the same account address as Address and SignerAddress, signeraddress and blsproofofpossession are the default values of the account address.

Second you need compile your atlas-contracts project,we need the bytecode about atlas-contracts to make genesis.json file.

Please refer to Deployment of contract related to validator

then to do so run:

USAGE
  $ ./marker genesis

OPTIONS
  --buildpath:  buildpath is the path to truffle compile output folder.
  
  --newenv:   the genesis.json will be generated under this folder 

  --markercfg:  this your markerConfig.json path default to github.com/mapprotocol/atlas/marker/config/markerConfig.json
                                                     
  
EXAMPLES:

marker genesis --buildpath ./root/atlas-contracts/build/contracts --newenv ./root/atlasEnv --markercfg "./root/atlas/marker/config/markerConfig.json"


This will create a `genesis.json` in the ./root/atlasEnv folder

ps: you can use this genesis.json init MAP validator nodes

  • you can update the chainid in the genesis.json

  • the one way: like this ./atlas --datadir ./node-1 init ./genesis.json

  • the other way: copy the alloc info in the genesis.json to core/chain/genesis_alloc_mainnet.go file overwrite mainnetAllocJSON info
