The present disclosure involves systems, software, and computer implemented methods for providing rapid approval of blockchain-based transactions. This includes approval of transactions prior to the transaction being written to the blockchain. A transaction system can register with a transaction manager, such as a cloud-based or cloud transaction manager, which can maintain a queue of pending transactions and provide approval for transactions in real-time or near real-time, while later verifying the pending transactions are written into the blockchain as expected. This allows the transaction system to securely confirm the transaction is approved prior to the transaction being written in the blockchain, based on a real-time or near real-time analysis of each customer's corresponding account and transactions.

Certain aspects of the present disclosure provide techniques for reliable cryptocurrency rebroadcasting. According to certain embodiments, after an initial transaction broadcast disclosed systems listen to a blockchain to determine if the transaction was included in the blockchain. If, after a short time period, the transaction is not confirmed, a transaction database record for the transaction is locked to prevent inadvertent rebroadcast. While the record is locked, the transaction format and replay information are verified, and depending on the blockchain, is updated. For blockchains having a transaction fee, the system reviews recent transactions to determine appropriate fees and if needed, updates the transaction fee accompanying the transaction. Once the replay information is verified/updated, and the transaction fee is sized appropriately, the database record is unlocked and the transaction is rebroadcasted.

Methods and devices for propagating blocks in a blockchain network. At a first mining node, while hashing a first block header of a first candidate block, the first mining node sends, to other mining nodes, a first message specifying transactions and their order in a first ordered set of transactions contained in the first candidate block. To prevent the other nodes from relying on the first mining node having validated the transactions in the candidate block, the first mining node seeds the first ordered set with one or more invalid transactions to create a poisoned ordered set, and provides an encrypted list identifying the invalid transactions. Once a proof-of-work is found for the candidate block, the first mining node provides a decryption key to decrypt the encrypted list and identify the invalid transactions. It may further provide replacement transactions for the invalid transactions.
