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
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.
