With the rapid growth of user requirements, more challenges are brought to the underlying public blockchain. How to solve the scalability of public chain has become a problem that blockchain technology developers are constantly thinking about. Meanwhile various solutions have been innovating.
By summarizing years of experience in blockchain technology development, Hubble Chain carried out technical innovation on the early POR reputation consensus algorithm and created the H + POR hybrid consensus algorithm. The optimized H + POR supports sharding technology and effectively improve the operation efficiency and safety performance of Hubble Chain.
The development of sharding technology drew on the partitioning technology in the classic database.When the data throughput is high, the reading and writing of the database will take a long time.When the data throughput is very high, it will take a long time to read and write the database. The technical team will store the data in different tables of different databases to enhance the network data throughput, so as to solve the capacity expansion problems for on-chain information.
In the operation process of sharding, firstly, a group of sharding nodes and leader nodes are defined in all transaction nodes. Then the distributed random number generation algorithm is used to select sharding nodes and leader nodes.
Afterwards, the sharding node is responsible for shunting and converging to the leader node. Through the system clock, the sharding node and the leader node keep synchronization, and can synchronously verify the correctness of the transaction. The system clock acts as an information channel to ensure the consistency between the leader node and the sharding node.
Finally, each sharding node adds a tag sequence ID to the transaction processed by itself. The leader node and voting node can confirm the transaction by verifying the ID.
In addition, sharding technology, which has a relatively complete theoretical system, can effectively reduce transaction costs and reduce the processing capacity of verifying a single transaction without affecting decentralization and transparency.
In the offline scope, sharding can also combine low-cost with high transaction processing capacity to continuously empower Hubble Chain ecosystem.
At present, Hubble Chain ecosystem development is sound and steady, and its scale is gradually expanded, which shows the advantages brought by sharding technology.
There are still many challenges in the existing sharding technology, but it can really make a difference to the scalability of the public bockchain. With the continuous breakthrough of development progress, the Hubble Chain sharding technology will lead the industry into a new stage.
