Abstract: A system for determining forgery or falsification of a digital content using a WebAssembly-based blockchain platform including a blockchain network, includes a client device configured to provide an original digital content to a relay server; the relay server configured to generate a hash for the original digital content provided from the client device and transmit the hash to a blockchain network; and a plurality of nodes configured to perform mining on a block including a transaction generated by distribution of a smart contract for the original digital content to distribute the mined block on the network, and perform comparison and verification between the smart contract for the original digital content included in the mined block and a smart contract for a digital content created using the original digital content, on a WebAssembly virtual machine.
