CrossCert BlockChain Differentiators

CrossCert developed an in-house Blockchain database solution using the Ethereum platform to provide public Blockchain services. Clients can now enjoy maximum data integrity by deploying our Blockchain solutions.





I. About The Crosscert BlockChain

CrossCert deploys a customized version of Ethereum’s open source for its in-house blockchain. Having developed its own blockchain-based data audit – and integrity tool, CrossCert has profound expertise in blockchain technology. This in turn enables us to guarantee maximum data integrity of our smrat contract signing services.

II. Key Features

Private Blockchain-based distributed DB solutions developed in-house, in cooperation with Seoul National University in Seoul, Korea

Contributing to Ethereum’s open source

CrossCert participated and contributed to the improvement for Ethereum’s open source

Profound expertise in developing complex, in-house Blockchain solutions

High-Speed Algorithm

Non-competitive consensus algorithm

This reduces the reliance on computing power and the traffic volume compared to competitive algorithms like PoW (Proof of Work)

Highly suitable for low-speed networks

Smart Contracts

Audit system powered by Blockchain 2.0-based Ethereum

Supports solidity-based development environment


Blockchain solves performance deterioration and encrypted key management issues that come from increases in data volume.

Expanded Conditions for Transaction Search

Removing threshold with the existing TxID-based transaction search

Node Authority Management

Managing access, search, and use of nodes

III. How it Works

CrossCert’s private Blockchain-based DB platform uses Async method functions to add and search Blockchain transactions. This unique capability is added to prevent transaction holding until data is confirmed, which frequently takes place in low-speed network environments.

Use Case: Blockchain-based customer reward service for local commerce (“Bitcoupon”)
