Mina Protocol / Mina Explained

Oracles bring real world information from Web2 on chain. But today, oracles rely on trusted parties or elaborate consensus schemes.

zkOracles, which are currently in development at O(1) Labs, represent a major leap toward trustless and private oracles through the power of Transport Layer Security (TLS) and zero knowledge.

Mina Protocol – the world's lightest blockchain

Mina builds on Cardano Protocol's Ouroboros to create Ouroboros Samisika, a provably secure PoS protocol that combines the best features of each iteration of Ouroboros to deliver a PoS mechanism that can resolve long-range forks without requiring history or risking centralization.

In this video, we break down Ouroboros Samisika so that it is as simple as playing a game of darts! 🎯

What is Mina?

Mina is the world’s lightest blockchain, powered by participants. Rather than apply brute computing force, Mina uses advanced cryptography and recursive zk-SNARKs to design an entire blockchain that is and always will be about 22kb, the size of a couple of tweets, ushering in a new era of blockchain accessibility. With its unique privacy features and ability to connect to any website, Mina is building a private gateway between the real world and crypto—and the secure, democratic future we all deserve. Mina is stewarded by the Mina Foundation, a non-profit organization.

Mina Protocol – the world's lightest blockchain

PoS (proof-of-stake) blockchains are more energy-efficient than PoW (proof-of-work)— but what does that mean? In this video, we simply explain what these two consensus mechanisms are and how they compare.

❓What are the pros & cons of PoW?

zk-SNARKs keep Mina's blockchain light and your personal data private – but there's even more going on behind the tech. In this video, Brandon simply breaks down what zk-SNARKs are by comparing them to the game of "Where's Waldo?" By the end of this video, you'll know what they are, how they work, and their importance to Mina and the greater crypto community!

❓What’s something interesting that you may want to prove with zk-SNARKs?
