1. New technology and platform architecture already well-established in Northern Europe
Postchain, a so-called Blockchain 2.0 new technical architecture, is a blockchain platform developed by Chromeby of Sweden. It features a new technical platform architecture that breaks through the limitations of "decentralized records" and integrates blockchain with "decentralized databases". Using Postchain does not require re-learning the underlying blockchain technology. Application developers can feel at ease developing blockchain applications as long as they have SQL database management language abilities. In Sweden and India, Postchain has already been used in real estate and land sales as well as in registration applications.
2. Balances blockchain processing efficiency with data privacy
Due to not having a database, other general blockchain platforms can only record a small amount of critical data; and further, the data cannot be indexed. As a result, while searching for data, the application system can be extremely slow and inefficient. Additionally, because the original data is placed on the local application database, it may differ from the records stored on the blockchain.
Using Postchain not only allows Rich Data to be stored on each node, but also incorporates a database. It also makes the data processing of the application system more efficient through database indexing and searching capabilities. Furhurmore, the database also has complete security capabilities such as identity restrictions and data encryption. This system is more suitable for private blockchain applications that focus on data privacy compared to the transparently distributed nodes.
Postchain uses the Byzantine Fault Tolerance (PBFT) consensus method. As long as two-thirds of the nodes in the network are functioning properly, a consensus can be reached. If a node fails to synchronize, it can still retrieve the missing data from its node and rejoin the synchronization program at a speed of 160 - 500 transactions per second.
