sCrypt reimplement ZKKSP by leveraging the programmability of zkSNARKs. They simply combine elliptic curve point multiplication used in Part 2 and hashing library that resulted to Circom code.
sCrypt shows how to implement another sophisticated cryptographic primitive by simply “programming” it in zero knowledge language Circom: ring signatures.
Developing a ZKP for a problem often requires the invention of a whole new cryptographic algorithm. It has no standard recipe and requires extensive and in-depth knowledge of cryptography.
sCrypt CEO Xiaohui Liu pointed out that smart contracts were part of Satoshi’s vision back in 2009, but the BTC cartel pushed them out so they could curtail BTC to mere speculation.
As the smart contracts are stored on the immutable blockchain ledger, they can never become lost, fire damaged, or disappear. Once in place, they will be there forever.
The MiMC hash function is specifically designed to minimize circuit size and thus ZKP cost by using only additions and multiplications.
In this post, sCrypt implemented the first-ever ZK-Rollup (ZKR) directly on Bitcoin. They also showed why ZKR works better on Bitcoin than on Ethereum.
zk-SNARK is a powerful primitive for blockchain privacy and scalability, and in this article, sCrypt showed what zk-SNARK is and how to implement it on Bitcoin.
Bitcoin Association for BSV represented Bitcoin SV at WeAreDevelopers World Congress in Berlin with more than 8000 attendees. The association sparked great interest in Bitcoin SV on an excit-ing market and during an important stage for the BSV ecosystem.
sCrypt have demonstrated how to verify a single BLS signature on Bitcoin and how BLS’s main power lies in aggregated signatures and keys.
The transpiler facilitates developers to migrate their applications onto the Bitcoin network from Ethereum and other Solidity/EVM-compatible blockchains without writing code from scratch.
In this article, sCrypt demonstrates how pairings can be implemented directly on Bitcoin and thus enable all kinds of pairing-based cryptography applications previously thought impossible.
