Abstract

A method includes acquiring, at a node server, blockchain data for a blockchain address on a blockchain network. The blockchain data includes a plurality of transactions for the blockchain address. The method includes generating a local node trust score for the blockchain address based on the blockchain data. The local node trust score indicates a likelihood that the blockchain address is involved in fraudulent activity. The method includes receiving, from a plurality of remote servers, a plurality of additional local trust scores for the blockchain address. The method includes determining a consensus trust score based on the local node trust score and the plurality of additional local trust scores. Additionally, the method includes monitoring a ledger on the blockchain network for a contract trust request that specifies the blockchain address and sending, to the blockchain network, the consensus trust score for the blockchain address specified in the contract trust request.

Claims20

Dependent claims

A method comprising:

acquiring, at a node server, blockchain data for a blockchain address on a blockchain network, wherein the blockchain data includes a plurality of transactions for the blockchain address;
generating, at the node server, a local node trust score for the blockchain address based on the blockchain data for the blockchain address, wherein the local node trust score indicates a likelihood that the blockchain address is involved in fraudulent activity;
receiving, from a plurality of remote servers, a plurality of additional local trust scores for the blockchain address;
determining, at the node server, a consensus trust score based on the local node trust score and the plurality of additional local trust scores, wherein the consensus trust score indicates a consensus value for the local node trust score among the node server and the plurality of remote servers;
monitoring a blockchain ledger on the blockchain network for a contract trust request that specifies the blockchain address;
and
sending, to the blockchain network, the consensus trust score for the blockchain address specified in the contract trust request.

4 more elements

A system comprising:

one or more memory components configured to store blockchain data for a blockchain address on a blockchain network, wherein the blockchain data includes a plurality of transactions for the blockchain address;
and
one or more processing units configured to execute computer-readable instructions that cause the one or more processing units to:
generate a local node trust score for the blockchain address based on the blockchain data for the blockchain address, wherein the local node trust score indicates a likelihood that the blockchain address is involved in fraudulent activity;
receive, from a plurality of remote servers, a plurality of additional local trust scores for the blockchain address;
determine a consensus trust score based on the local node trust score and the plurality of additional local trust scores, wherein the consensus trust score indicates a consensus value for the local node trust score;
monitor a blockchain ledger on the blockchain network for a contract trust request that specifies the blockchain address;
and
send, to the blockchain network, the consensus trust score for the blockchain address specified in the contract trust request.
