Xblock Systems Tuesday unveiled its main net to prevent forgery and fabrication.

In a ceremony in Seoul, it said its main net is one step away from commercialization. It said its main net overcame the blockchain’s drawbacks, including slow speed, computing power, and node operations.

Xblockchain could prevent forgery of all public documents, including school records, the origin of country documents and other government documents. All do e-documents could be recorded in Xblockchain.

It would start a trial operation for recording public documents in South Korea. It would open a joint venture in Singapore for overseas projects, the company said.
