< SPAN class=" qL-size-13 qL-font microsoftyahei qL-author-58030660 ">Mina is a "lightweight" smart contract platform, To become a global payment system. Address scalability issues in existing blockchains where the cost of validating a blockchain grows proportionately to total transaction throughput. In these cases, the cost of running network nodes ends up exceeding the resources available to most real-world users.
< SPAN class=" qL-size-13 qL-font microsoftyahei ql-author-58030660">Mina's goal is to design a decentralized payment system, The system can effectively verify the history of the system from creation without relying on any external information. This is done with the following attributes:
- < SPAN class=" qL-size-12 qL-font microsoftyahei ql-author-58030660"> Use incrementally computable SNARK to model generic functions as replication state machines.
< SPAN class=" qL-size-13 qL-font microsoftyahei ql-author-58030660"> The simple blockchain is made by zK-SNARks Is implemented by a recursive combination, which uses a proof of constant size for arbitrarily incremental computations. This means that the complexity of the validation chain is independent of its size, but users can easily participate actively in the network. Instead of preserving the entire chain to prove its existence, users simply use SNARK (concise non-interactive knowledge argument) to preserve the current state.
< SPAN class=" qL-size-13 qL-font microsoftyahei ql-author-58030660"> This allows Mina to scale up to thousands of transactions per second, And requires orders of magnitude fewer resources to maintain than a PoW blockchain.
