修改bootnode
bootnode
1 修改core/types/block.go中Header的结构体。加上
Signature []byte `json:"signature" gencodec:"required"`
2 在p2p/discover/udp.go中修改

return nodes

1 修改core/types/block.go中Header的结构体。加上
Signature []byte `json:"signature" gencodec:"required"`
2 在params/bootno
de.go 中加上自己的bootnode
"enode://3ccd479f747ac233649fd6013f6bc1676ce55f9e2ba3d415c16fe663dc20a172a7450f20f96d2c640b6431a9f5bcad34bdb4a287dbe1bcf2d7c658edae810bd6@192.168.70.183:10101"
3 在concensus/ethash/sealer.go中加上

// No persistent key found, generate and store a new one.
key, err := crypto.GenerateKey()

log.Crit(fmt.Sprintf("Failed to generate node key: %v", err))

在verify.sealer.go中对区块的签名验证
if

var signer common.Address
copy(signer[:], crypto.Keccak256(pubkey[1:])[12:])

}verify no sig then give sig 77 [66 167 41 73 93 40 200 178 78 5 62 159 38 140 57 1 211 206 48 58 113 155 1 96 46 43 150 18 79 166 137 18 80 55 31 69 0 173 151 243 253 177 229 42 82 220 31 117 164 177 150 231 22 165 99 0 108 134 236 187 204 106 68 206 1]
