From 6244b10a8f74d92addf977994e5a9c0e457229bb Mon Sep 17 00:00:00 2001 From: obscuren Date: Mon, 8 Jun 2015 12:12:13 +0200 Subject: core: settable genesis nonce You can set the nonce of the block with `--genesisnonce`. When the genesis nonce changes and it doesn't match with the first block in your database it will fail. A new `datadir` must be given if the nonce of the genesis block changes. --- core/genesis.go | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'core/genesis.go') diff --git a/core/genesis.go b/core/genesis.go index a9b7339f3..dd894e0b0 100644 --- a/core/genesis.go +++ b/core/genesis.go @@ -19,8 +19,8 @@ var ZeroHash256 = make([]byte, 32) var ZeroHash160 = make([]byte, 20) var ZeroHash512 = make([]byte, 64) -func GenesisBlock(db common.Database) *types.Block { - genesis := types.NewBlock(common.Hash{}, common.Address{}, common.Hash{}, params.GenesisDifficulty, 42, nil) +func GenesisBlock(nonce uint64, db common.Database) *types.Block { + genesis := types.NewBlock(common.Hash{}, common.Address{}, common.Hash{}, params.GenesisDifficulty, nonce, nil) genesis.Header().Number = common.Big0 genesis.Header().GasLimit = params.GenesisGasLimit genesis.Header().GasUsed = common.Big0 -- cgit v1.2.3
