Clockchain Launches Public Testnet to Build a Global Time Standard on Blockchain

A new blockchain network aims to make digital time secure, verifiable, and trusted across finance, AI, and global systems.

In a world where even a split second can impact financial trades or automated decisions, accurate timekeeping has become more important than ever. San Francisco-based Clockchain has officially opened its public testnet, introducing what it calls a blockchain-powered global time standard.

Unlike traditional blockchains that depend on timestamps reported by validators or miners, Clockchain uses patented technology to collect time data from multiple independent global sources. It then records a synchronized, cryptographically verified timestamp on the blockchain every second through decentralized consensus. This creates a uniform and tamper-resistant time reference that can be independently verified.

The newly launched testnet offers three key services: decentralized data logging and authentication, smart contract scheduling, and a secure Timestamp API. These tools allow businesses and developers to record events, schedule automated transactions, and verify digital records using trusted blockchain time.

“Most blockchains rely on validator-reported timestamps that were never designed to function as a global time authority,” said Ken Yamada, CEO of Clockchain. “Clockchain introduces a cryptographically verifiable reference layer that applications can anchor to when deterministic timing matters.”

The network has been running privately for over a year before opening to the public. By aligning with global UTC standards and integrating with platforms like Ethereum and Polygon, Clockchain aims to support decentralized finance, traditional finance, artificial intelligence, and robotics.
