METHOD AND SYSTEM FOR PREVENTION OF SPAM ATTACKS ON A BLOCKCHAIN NETWORK

Abstract:

A method for reducing spam transaction submission in a blockchain network includes: receiving a transaction request from a computing device; transmitting a computational challenge to the computing device; receiving an answer to the computational challenge from the computing device; receiving a new blockchain transaction from the computing device; validating the received answer to the computational challenge; and transmitting the new blockchain transaction to a plurality of blockchain nodes in a blockchain network upon successful validation of the received answer.
