• Zero-knowledge Proofs (zk-proofs) is a cryptographic technique that uses cryptography to prove the validity of information revealing the information to the public.
• ZeroSync has already developed a working prototype that allows users to validate who owns what and the transaction history on Bitcoin without having to download the entire chain or using a third party.
ZeroSync Association
Three German computer scientists have created a Swiss non-profit association called ZeroSync Association to help bring scalability to Bitcoin using zero-knowledge proofs (zk-proofs), a cryptographic technique whose popularity on Ethereum has surged considerably. The association has received sponsorship from Geometry Reaserch and StarkWare Industries. Geometry Reaserch is a crypto investment firm while StarkWare Industries is the software company behind StarkNet.
What Is Zero-Knowledge Proof?
Zero-knowledge Proofs, commonly referred to as zk-proofs, is a cryptographic technique that uses cryptography to prove the validity of information revealing the information to the public. By deploying kz-proofs on Bitcoin means nodes will be able to sync almost instantly compared to hours and sometimes days that it takes to download the chain’s current 500GB data.
Working Prototype
At the moment, ZeroSync has already developed a working prototype that allows users to validate who owns what and the transaction history on Bitcoin without having to download the entire chain or using a third party. The prototype can however only verify Bitcoin consensus rules but not transaction signatures. The prototype is also a bit chunky and still needs to be optimized for security and speed. When fully deployed on Bitcoin ZeroSync will allow verification of transaction of Bitcoin using cryptographic proof instead of trusting honest nodes as suggested by the Bitcoin founder Satoshi.
Bitcoin Scalability Issue
Bitcoin currently uses the proof-of-work (PoW) consensus mechanism which in a way limits its scalability. Its rival blockchain Ethereum also used PoW but changed to Proof-of-Stake (PoS) consensus mechanism through the Merge Upgrade in order solve this issue.
Conclusion
The aim of ZeroSync Association is provide scalability solution for Bitcoin by deploying zk proofs which would enable nodes sync almost instantly compared downloading chain’s current 500GB data, reducing time required for transactions validation without compromising security or privacy of users data or funds stored on blockchain network such as bitcoin
