I think it is doable and it is more secure to a compromised ECDSA. I'm thinking something like this for the scriptPubKey: 2 OP_SWAP OP_SWAP OP_SWAP OP_DUP OP_HASH160 OP_EQUALVERIFY OP_DUP OP_HASH160 OP_EQUALVERIFY OP_DUP OP_HASH160 OP_EQUALVERIFY 3 OP_CHECKMULTISIG and for the scriptSig Can anyone confirm or send me a link to the worked out script? Thanks -- PGP: B6AC 822C 451D 6304 6A28 49E9 7DB7 011C D53B 5647
