Mina Protocol (MINA)

Mina Protocol aims to create a “succinct” blockchain which minimises the amount of storage required to maintain all transactions on its blockchain. To do so, Mina Protocol employs zero-knowledge proofs called zk-SNARKs, which compress the transaction history of its Blockchain, reducing the size and resources required to maintain it. Mina’s blockchain is capped at a size of 22KB - roughly the size of two Tweets, compared to other blockchains which are roughly 300GB and ever growing. Mina Protocol’s native currency, MINA, is used as a means of payment for transactions on the network, as well as a rewards mechanism at the heart of its proof of stake network.
