Constants

const DefaultCliqueSigner = "" /* 236-byte string literal not displayed */

EIP-225 assigns a special meaning to the `extra-data` field in the block header for clique chains. In a clique chain, this field contains one secp256k1 "miner" signature. This allows other nodes to verify that the block was signed by an authorized signer, in place of the typical PoW verification. Clique overloads the meaning of the `miner` and `nonce` fields to implement a voting protocol, whereby additional signatures can be added to the list (for details see `Repurposing header fields for signing and voting` in EIP-225). https://eips.ethereum.org/EIPS/eip-225 The following value is for the key used by the e2e test "miner" node.

const DepositContractCode = "" /* 12156-byte string literal not displayed */

DepositContractCode is the compiled deposit contract code, via https://github.com/protolambda/merge-genesis-tools This is embedded into genesis so that we can start the chain at a merge block. const

Functions

func GethTestnetGenesis added in v3.2.1 

func GethTestnetGenesis(genesisTime uint64, cfg *clparams.BeaconChainConfig) core.Genesis

DefaultTestnetGenesis creates a genesis.json for eth1 clients with a set of defaults suitable for ephemeral testnets, like in an e2e test. The parameters are minimal but the full value is returned unmarshaled so that it can be customized as desired.

func SetupRPCServer
