Content suggestion: It can be a payment scenario, such as small-sum payments, cross-border payment business scenarios. At the same time, corresponding innovations on rapid payment are highly expected.   02 Smart contract scenario Based on the payment system, certain smart contracts scenarios can be extended. Is more appropriate for UTXO models to do some stateless smart contracts. Content suggestion: (1) If we use oracle as a deposit, the system will make a scenario of automatic chargeback according to the result. More contract scenarios can be built as BCH opens up more opcodes. (2) Newly opened opcodes can have some features of quiz games, without considering financial issues, atomic operations and smart contracts. Coins will be sent automatically based on the results. (Reference: https://github.com/fyookball/ChainBet)   03 Cross-chain business scenario That is, based on the cross-chain implementation of the gateway, based on the value network and ecology of BCH, what kind of block chain can be built? Content suggestion: Atomic trading, or using BCH to call a contract directly. (Reference: https://www.rsk.co/)   04 Side chain The use of a gateway in the sidechain to deliver the value of BCH. For example, RSK will also be implemented on the BCH soon.   05 Permanent storage of data The opening of OP_RETURN allows data to be saved permanently, and even defines its own protocol, such as memo. These protocols and data are open. Content suggestion: What kind of applications will appear with permanent storage of data, open protocols and open data. (Reference: https://memo.cash/)   06 Big data analysis There exists a lot of data, transactions, blocks, and nodes on the BCH network. If people handle well the data analysis and data visualization, it will be a global network. Content suggestion: Blockchain itself is a big data, on which people can do a lot of statistics, such as UTXO growth, statistics of mempool or address analysis.
