scriptPubKey: OP_DUP OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG
scriptSig: <sig> <pubKey>例如如下的raw scriptPubKey:
76A91489ABCDEFABBAABBAABBAABBAABBAABBAABBAABBA88AC
解析如下:
76 A9 14
OP_DUP OP_HASH160 Bytes to push
89 AB CD EF AB BA AB BA AB BA AB BA AB BA AB BA AB BA AB BA 88 AC
Data to push OP_EQUALVERIFY OP_CHECKSIG| Stack | Script | Description | |
|---|---|---|---|
| Stack | Script | Description | |
| Empty. | <sig> <pubKey> OP_DUP OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG | scriptSig and scriptPubKey are combined. | |
| <sig> <pubKey> | OP_DUP OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG | Constants are added to the stack. | |
| <sig> <pubKey> <pubKey> | OP_HASH160 <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG | Top stack item is duplicated. | |
| <sig> <pubKey> <pubHashA> | <pubKeyHash> OP_EQUALVERIFY OP_CHECKSIG | Top stack item is hashed. | |
| <sig> <pubKey> <pubHashA> <pubKeyHash> | OP_EQUALVERIFY OP_CHECKSIG | Constant added. | |
| <sig> <pubKey> | OP_CHECKSIG | Equality is checked between the top two stack items. | |
| true | Empty. | Signature is checked for top two stack items. |
