From 60dfddc9d05436981f68ba7d2b04312cf98ad956 Mon Sep 17 00:00:00 2001 From: Dave Collins Date: Wed, 24 Jul 2013 09:09:18 -0500 Subject: [PATCH] Use common coinbase transaction for Genesis blocks. Since the same coinbase transaction is used for the genesis blocks of all three currently supposed networks, separate it into its own var and use a reference to it in each of the genesis block defintions. --- genesis.go | 176 ++++++++++++++--------------------------------------- 1 file changed, 47 insertions(+), 129 deletions(-) diff --git a/genesis.go b/genesis.go index 8d7973f8..9eec1b4f 100644 --- a/genesis.go +++ b/genesis.go @@ -8,6 +8,50 @@ import ( "time" ) +// genesisCoinbaseTx is the coinbase transaction for the genesis blocks for +// the main network, regression test network, and test network (version 3). +var genesisCoinbaseTx = MsgTx{ + Version: 1, + TxIn: []*TxIn{ + &TxIn{ + PreviousOutpoint: OutPoint{ + Hash: ShaHash{}, + Index: 0xffffffff, + }, + SignatureScript: []byte{ + 0x04, 0xff, 0xff, 0x00, 0x1d, 0x01, 0x04, 0x45, /* |.......E| */ + 0x54, 0x68, 0x65, 0x20, 0x54, 0x69, 0x6d, 0x65, /* |The Time| */ + 0x73, 0x20, 0x30, 0x33, 0x2f, 0x4a, 0x61, 0x6e, /* |s 03/Jan| */ + 0x2f, 0x32, 0x30, 0x30, 0x39, 0x20, 0x43, 0x68, /* |/2009 Ch| */ + 0x61, 0x6e, 0x63, 0x65, 0x6c, 0x6c, 0x6f, 0x72, /* |ancellor| */ + 0x20, 0x6f, 0x6e, 0x20, 0x62, 0x72, 0x69, 0x6e, /* | on brin| */ + 0x6b, 0x20, 0x6f, 0x66, 0x20, 0x73, 0x65, 0x63, /* |k of sec|*/ + 0x6f, 0x6e, 0x64, 0x20, 0x62, 0x61, 0x69, 0x6c, /* |ond bail| */ + 0x6f, 0x75, 0x74, 0x20, 0x66, 0x6f, 0x72, 0x20, /* |out for |*/ + 0x62, 0x61, 0x6e, 0x6b, 0x73, /* |banks| */ + }, + Sequence: 0xffffffff, + }, + }, + TxOut: []*TxOut{ + &TxOut{ + Value: 0x12a05f200, + PkScript: []byte{ + 0x41, 0x04, 0x67, 0x8a, 0xfd, 0xb0, 0xfe, 0x55, /* |A.g....U| */ + 0x48, 0x27, 0x19, 0x67, 0xf1, 0xa6, 0x71, 0x30, /* |H'.g..q0| */ + 0xb7, 0x10, 0x5c, 0xd6, 0xa8, 0x28, 0xe0, 0x39, /* |..\..(.9| */ + 0x09, 0xa6, 0x79, 0x62, 0xe0, 0xea, 0x1f, 0x61, /* |..yb...a| */ + 0xde, 0xb6, 0x49, 0xf6, 0xbc, 0x3f, 0x4c, 0xef, /* |..I..?L.| */ + 0x38, 0xc4, 0xf3, 0x55, 0x04, 0xe5, 0x1e, 0xc1, /* |8..U....| */ + 0x12, 0xde, 0x5c, 0x38, 0x4d, 0xf7, 0xba, 0x0b, /* |..\8M...| */ + 0x8d, 0x57, 0x8a, 0x4c, 0x70, 0x2b, 0x6b, 0xf1, /* |.W.Lp+k.| */ + 0x1d, 0x5f, 0xac, /* |._.| */ + }, + }, + }, + LockTime: 0, +} + // GenesisHash is the hash of the first block in the block chain for the main // network (genesis block). var GenesisHash ShaHash = ShaHash{ @@ -38,49 +82,7 @@ var GenesisBlock MsgBlock = MsgBlock{ Nonce: 0x7c2bac1d, // 2083236893 TxnCount: 1, }, -
