Abstract: Disclosed embodiments include techniques to increase the probability that network validators will include a specific transaction in a target block of a blockchain. The method includes creating and signing in real-time a transaction and loading copies of the transaction at agent nodes connected to a network of peer nodes. An agent node can obtain an indication of an opportunity to write the transaction to a target block. The method can further include broadcasting the transaction to the network of peer nodes based on the obtained indication of the opportunity to write the transaction, to improve a probability of having the transaction written to the target block.
