Abstract: A method for distributing event data for smart contracts executed on a blockchain to subscribing systems includes: collecting, by a processor of a blockchain node in a blockchain network, a set of event data emitted by a smart contract executed on a blockchain associated with the blockchain network; identifying, by the processor of the blockchain node, communication data for one or more subscriber computing systems; and after a predetermined period of time, transmitting, by a transmitter of the blockchain node, the collected event data to each of the one or more subscriber computing systems using the communication data.

Abstract: A method for posting of anonymous directed transaction includes: storing a plurality of entity profiles, each including an entity identifier and a secret value; receiving a transaction request from a first entity, the request including transaction data and a specific entity identifier associated with a second entity; identifying a specific entity profile that includes the specific entity identifier; generating a first hash value via application of one or more hashing algorithms to the transaction data; generating a second hash value via application of one of more hashing algorithms to a combination of the first hash value and the secret value included in the identified specific entity profile; and posting the first hash value and second hash value to a publicly accessible data source.
