double-sig transaction invalid address, Unable to broadcast multi-sig transaction that has been double signed

2021-05-31 00:00  Category : Transaction  

Determine whether the UTXO identity of the transaction involved in the transaction message is the UTXO in circulation. If not, this UTXO is fake. Determine whether the owner of the UTXO in the transaction message is consistent with the owner of the UTXO in the book of the central bank's digital currency registration system. If this is not consistent, this UTXO may be forged or attempted to be double-flowered. Determine whether the signature of the transaction message can be properly verified by the public key of the UTXO owner. If the verification fails, the transaction is not initiated by the owner of UTXO and is a forged transaction. Determine whether the payer address specified in the transaction message is a user address registered in the central bank's digital currency registration system. If the payer address does not exist, the transaction is rejected, otherwise the digital currency transferred to the invalid payer will not be able to continue circulating because no one knows the private key corresponding to the invalid payer (equivalent to the note being burned out)

verify checkTxSig (key, sig) detects whether a given signature matches a pre-set public key and a transaction that unlocks the contract.

When a transaction is successful, the coupon is automatically removed from the customer's wallet and placed in a "burn address" or address associated with an invalid coupon to prevent the user from redeeming the coupon multiple times.

Contribute code and models: TensorFlow has several SIG groups, and there are many developers in the Chinese community who lead these SIG groups, such as SIG Networking, SIG IO, SIG AddOns, and welcome to the TF SIG group, contribute code, and contribute models.

Penalty invalid exit: If the operator permits an invalid "exit" transaction, we can punish it and forfeit the security deposit.

Each transaction in the Ethereum network has a nonce, which represents the number of transactions sent by the address, and nonce helps to arrange all transactions sequentially in order to prevent double-spends (double flowers)

The gen_token is made into an expiration timestamp, which is the function (key, expires). If expires , nil then expires , os.time() , 60 , 60 8 ends , base64 encoding the msg section. local msg encode_base64 (json.encode ('key s key, expires 'expires') -- sha256 hashed. local signature encode_base64 (hmac_sha256 ('testkey', msg)) -- stitched together into a token.

If not (sig sig)hmac_sha256 ('testkey', msg)) then return nil, "invalid csrf token (bad sig)" end -- base64 decode msg to determine whether the keys in them are consistent with the keys that are passed in. --Token is also invalid if it is not consistent. Msg .json.decode (decode_base64 msg)) if not (msg.key s key) then return nil, "invalid csrf token (bad key)" end -- remove the timestamp of the msg part to determine whether it is greater than the current time, if greater than, the token expiration is invalid. if not (not msg.expires or msg.expires os.time)) then return nil, "csrf token expired" endend.

We've added another rule, and the exit challenge must also provide a confirmation signature. Now, if the authenticator includes the user's transaction in the block after an invalid transaction has been made, the user will not sign a confirmation signature at all. Transactions contained after an invalid transaction will not have a confirmation signature and will therefore be invalid. As a result, every user who follows the right behavior gets their money.

It doesn't matter if someone owns one-tenth of a bitcoin or ten thousand bitcoins. Both are protected and validated through the same mechanisms and the same rules. Everyone has equal rights. Regardless of economic value, every Bitcoin (and Bitcoin address) is treated equally in the Bitcoin network. If a valid signature is generated, the transaction is valid and it is added to the blockchain (if a transaction fee is paid). If an invalid signature is generated, the network rejects it as invalid. It doesn't matter if any particular participant is powerful or weak.

When the transaction is sent out, the wallet, especially the mining node, verifies the transaction, which verifies the above signature results, verifies the sender's public key (pub) and signature information mes, and verifies the ver (sig, pub), which verifies that the transaction is legal.

Transaction is invalid. Details are athned by the error code.

And if user A initiates a double-flower transaction tx2, tx2 is made up of: an Input1, an address of user A, and a zero address of user A. This tx2 must contain a signature on "data1"
