1. Consensus basis In the MTC chain, nodes are divided into two types: light nodes and full nodes. The light node does not participate in the consensus, and only saves the transaction data of the hash tree with itself; the whole node participates in the consensus and stores all the transaction data that occurs. In the MTC chain, there are 3 types of transactions: ordinary transactions, contract transactions, encrypted transactions, general transactions directly into the warehouse; contract transactions are triggered by smart contracts and virtual machines, with high security, autonomy, etc.; Technology such as ring signature, after the data of the encrypted transaction is consistent through consensus, the smart contract is used to perform the warehousing operation, and in order to avoid the double flower problem, we will have more ways to deal with it. 2. Features: Large data throughput: After practice certification, the throughput of the MTC chain reaches 1000 pieces per second. The transaction rate is fast: the new block generation time is 2-10 seconds, which greatly promotes the commercialization project compared with 10 minutes of Bitcoin and 1 minute of Ethereum. High fault tolerance: Supports 50% of fault tolerance as Bitcoin. For an attacker, the attacker needs to spend 50% of the cost to change the ledger of the transaction data. Low transaction fees: only a small transaction fee is charged for each transaction, which makes electronic payment shine in areas such as cross-border transfers and frequent micropayments. High security: Due to the use of integrated technology, security has been greatly strengthened. Such as smart contracts, virtual machines, ring signatures, encryption algorithms, and more.
