在 巴西 購買 Mina Protocol (MINA)

Mina Protocol is a crypto/Web3 project known for its "succinct blockchain" design, aiming to be the world's lightest blockchain. Its core objective is to reduce computational requirements for running decentralized applications (DApps) efficiently and to maintain a constant blockchain size, around 22 kilobytes, regardless of how much usage it experiences. This small size is comparable to a few tweets or a small image file. The project's key innovation lies in its use of Zero-Knowledge Succinct Non-Interactive Arguments of Knowledge (zk-SNARKs). Instead of requiring users and nodes to verify the entire history of transactions, Mina represents the entire blockchain state as a small, easily verifiable cryptographic proof or "snapshot" using recursive zk-SNARKs. This means that users only need to check this compressed proof rather than the full transaction history, making the network accessible to a wider range of participants, even those with limited computing power like smartphones. By keeping the blockchain size consistently small, Mina Protocol seeks to overcome scalability and decentralization challenges faced by traditional blockchains, which tend to grow indefinitely. This design promotes a more decentralized network by lowering the barrier to entry for individuals to run a full node and participate in securing the network. Mina operates on a Proof-of-Stake (PoS) consensus mechanism, specifically using Ouroboros Samasika. The native cryptocurrency of the protocol is MINA, which facilitates network transactions, staking, and incentivizes participants such as block producers and "snarkers" who generate the zk-SNARKs. The project was initially launched as Coda Protocol in 2017 by O(1) Labs and was rebranded to Mina Protocol in October 2020. Its mainnet went live in March 2021. Mina also supports zkApps (zero-knowledge applications), which are advanced smart contracts offering features like enhanced privacy, off-chain computation, and on-chain verification. These zkApps are built using SnarkyJS, a TypeScript-based library, making it easier for developers to create privacy-preserving decentralized applications. Overall, Mina Protocol aims to provide a secure, private, and verifiable internet by offering a lightweight and accessible blockchain infrastructure. 瞭解更多
