VeriBlock and its novel Proof-of-Proof (“PoP”) consensus protocol is the first and only technology in the world to allow any blockchain to inherit Bitcoin’s unprecedented thermodynamic Proof-of-Work security in an entirely Decentralized, Trustless, Transparent, and Permissionless (“DTTP”) manner. Since September of 2018, thousands of PoP miners in over 50 countries have successfully done more than 6,000,000 PoP transactions to Bitcoin, accounting for nearly half of all Bitcoin transactions at peak. Over the past four years, the VeriBlock project has attracted strategic investors, partners, and advisors including Bittrex CEO Bill Shihara, Bloq Co-Founder and Chairman Matthew Roszak, Bloq Co-Founder and Former Bitcoin Core Developer Jeff Garzik, Ethereum and Decentral Co-Founder Anthony Di Iorio, and Fenbushi Capital General Partner Bo Shen.
The key to Space Chain is to deploy all blockchain nodes on satellites so as to bring blockchain technology into space, adding a new dimension to blockchain’s core concept of distributed ledger by making use of space technology and advantages of space resources. As a space blockchain platform featuring data collecting, computing, application and storage, Space Chain uses satellites as its blockchain nodes for realizing direct on-satellite data processing and secure in-space data storage through cryptographic technologies such as quantum communications. Different from ground-network-based blockchain technology, Space chain provides a broader coverage and is based on a network of LEO satellites for achieving broad-based connectivity so that anyone and anything could become the user of blockchain technology anywhere and anytime.
