Last Friday ( July 31, 2020), aelf hosted an AMA about hacker bounty and CCTP on Twitter, featuring aelf’s dev advocate, Ace. Below is a transcript of the questions and answers.
Q1: Why aelf Committed to Establishing a Unified Cross-Chain Protocol? And what does it take for increased use-cases and value of your Cross-Chain protocol?
Ace: The protocol is a standard for various user cases, business and scenarios, and with it, aelf can build the whole ecosystem based on the standard, mitigating the cost of designing different cross-chain methods in face of different type of scenarios. We will try to develop more and more popular and real-problem solving dapps on aelf blockchain, better develop many dapps of different type of scenarios.
Q2: What is the uniqueness and what is the purpose of the CCTP protocol, what problems does it solve and what is it applicable to?
Ace: It can support any kind of cross-chain asset transferring services whether the chains are mutually compatible or not. It can be used to transfer money value between different chains, transfer asset between these chains, and prove if an asset’s ownership exists. We can use it to any scenarios described above, for example some financial business
Q3: How does protocol achieves cross-chain transfers between independent blockchain systems?
Ace:: aelf use merkle proof to ensure the elf erc20 token is really locked and transfer equal value of elf token to the same user on aelf blockchain.
Q4: Whether the standard protocol of cross chain transfer of aelf has been attacked and destroyed in this hacker reward offering activity, and will it also be used in the main network mapping? I’m still looking forward to it.
Ace: Till now no one could ever do that, and the CCTP is absolute used for mainnet, otherwise ...
