ONE Harmony

Bitgetについて Harmony

Harmony's goal is to build a shard-based blockchain that is fully scalable and secure. It has studied many blockchain solutions on the market and proposed its own project implementation plan. This is where Harmony deserves everyone's attention. This is a high goal. First of all, it has complete scalability. Harmony's sharding includes not only transaction confirmation, network communication, but also sharding of the blockchain state. The second is to ensure the security of shards. Harmony's sharding is based on the DRG (Distributed Random Generation) process, which makes it unpredictable, fair, verifiable, and scalable. In addition, Harmony adopts PoS mechanism instead of PoW mechanism to select validators, and it has its own optimization for the PBFT consensus mechanism. PoS has a certain threshold, which not only ensures that small stakers can participate in the network and earns income, but also prevents malicious attackers from gaining control over a single shard. Harmony implements information dissemination within and across shard networks by using an Adaptive Information Dispersal Algorithm. Harmony also uses Kademlia routing to achieve logarithmic scaling of cross-shard transactions as the number of shards increases. With sharding, it is also necessary to maintain the consistency of cross-shard transactions. Harmony also supports cross-shard transactions, supports direct communication between shards, and ensures the consistency of cross-shard transactions through an atomic locking mechanism. All in all, by optimizing the protocol layer and network layer, Harmony tries to provide a scalable, secure and decentralized blockchain that can support more mainstream decentralized application scenarios, including games, decentralized Centralized exchanges, IoT, etc. It's an ambitious vision.
