Polygonthe popular scaling solution for Ethereumand Mina Protocol, a lightweight, smart contracts platform, announced a bridge to merge the two technologies.
Billed as the “smallest blockchain in the world”, the Mina protocol weighs only a few kilobytes compared to Ethereum’s 300 gigabyte blockchain. This means that synchronizing the Mina network is also much easier for the average user; instead of heavy hardware requirements, you can run a full Mina node from your smartphone.
It is able to condense its network to this size through its use of zero-knowledge proofs, privacy-centric cryptography.
Today’s collaboration means developers can now build apps on Polygon using Mina’s zk-SNARK-enabled recursive apps, or “Snapps.”
The technical jargon can be summed up as follows: using evidence without knowledgethese types of apps can hide certain functionality from different parties.
Instead of being able to quickly find out who owns the most expensive non-fungible token (NFT) on Polygon, Snapps could hide the identity of the owner. The same for sensitive KYC information; a crypto protocol that needs these details could use a Snapp to assert, without exposing, key information like a passport number or date of birth.
Essentially, developers will now have the ability to include privacy features in any app they now build on Polygon.
“Building a bridge between Polygon and Mina is an important step towards realizing our shared vision of a fully decentralized ecosystem of dapps that puts users in control of their data,” said Polygon co-founder Sandeep Nailwal.
Polygon goes private
The combination reinforces Polygon’s focus on improving scalability through privacy-preserving technologies. In August, the Scalability Project acquired Hermez, a scalability solution that uses zero-knowledge rollups, for 250 million MATIC tokens.
