Abstract: A network node in a peer-to-peer network of nodes includes at least one processor, at least one memory, and at least one network interface. The at least one processor is configured to receive a request to transfer a security token and execute a plurality of compliance rules associated with the security token. At least one of the compliance rules is implemented using at least one smart contract. The at least one smart contract references a global registry. The at least one processor is also configured to transfer the security token based on the execution of the compliance rules. The global registry includes personally identifiable information (PII) hash(es) for each of at least one investor associated with the transfer of the security token. The hashes are committed to the distributed ledger and updated when PII of a respective one of the at least one investor changes.

Abstract: A method includes generating first messages having a first message type, at a first subset of network nodes in a peer-to-peer network, based on requests received from a first external computing device; submitting second events to the peer-to-peer network, the first events having payloads that are based on the first message type; and using at least one directed acyclic graph (DAG) to attempt to reach a consensus about timestamps in the first events. The method also includes receiving, at a second subset of network nodes, events having different payload types from the peer-to-peer network and filtering for first events having payloads based on the first message type; and when one of the second subset of network nodes receives a first event having a payload that is based on the first message type, converting the payload into a second message that is sent to a second external computing device.

Abstract: A network node that includes at least one processor, at least one memory, and at least one network interface is disclosed. The network node is part of a peer-to-peer network of network nodes implementing a distributed ledger. The network node is communicatively coupled to at least one remotely located computing device through the at least one network interface. The at least one processor is configured to receive, from a remotely located computing device, a request to transfer a security token. The at least one processor is also configured to execute a plurality of compliance rules associated with the security token. At least one of the compliance rules is implemented using at least one smart contract. The at least one smart contract references a global registry.
