The Sui blockchain is a new blockchain platform that aims to provide an efficient, secure, and scalable infrastructure for decentralized applications (dApps). The Sui blockchain is designed to support smart contracts and uses a unique consensus algorithm called Proof of Believability (PoB) that combines the advantages of Proof of Work (PoW) and Proof of Stake (PoS) consensus algorithms.
As for an “airdrop,” it typically refers to a marketing strategy used by blockchain projects to distribute free tokens to members of the community. Airdrops are used to increase awareness about the project and to incentivize people to participate in the platform’s ecosystem. However, I’m not aware of any specific airdrop related to the Sui blockchain at this time.
