ZeU – Legacy Databases Applications Can Now Be Blockchain Enabled
ZeU – Legacy Databases Applications Can Now Be Blockchain Enabled
-FOR IMMEDIATE RELEASE-
Montréal, December 5, 201 9 – St-Georges Eco-Mining Corp. (CSE: SX) (OTC: SXOOF)
(FSE: 85G1) is pleased to announce that its subsidiary, ZeU Crypto Networks Inc. , has filed a
new provisional patent entitled “Method and System for Converting Database Applications into
Blockchain Applications.” The new IP provides a convenient method for combining traditional
applications with blockchain technology.
This method does not require any modifications to existing applications. On the database layer,
we directly ensure data in the database maintains synchronization with the data in the
blockchain. Traditional enterprise applications are database -based applications, and all business
services are built upon relational or non -relational databases. A common problem in the process
of migrating from enterprise applications to blockchain applications is that the overall structure
of blockchain is very different from traditional en terprise applications. Enterprise applications
must be significantly modified or even rewritten to fit the structure of blockchain’s logic.
This patent provides a method and system for converting database -based applications into
blockchain-based applicatio ns; multiple applications on different nodes can automatically
perform global data consensus to prevent data conflicts. The basic method is to monitor the
database written by applications, extract data operations from transaction logs, convert the data
operations to a general format, and activate the smart contract on the blockchain to complete the
data consensus check at multiple nodes. Each node monitors the blocks on blockchain and
synchronizes the data back to the database. In the case of conflicting or illegal data, the data is
not able to pass consensus and synchronize with the other nodes in the blockchain. The local
nodes automatically roll back when detecting invalid data.
Example 1: Electrical Certificate
In this case, when a record is generated lo cally, and it needs to be retrieved later for
confirmation, such as legal documents, bank orders, etc. Traditionally a centralized database has
been used to store the data and validate the conflicts. With the method in this patent, traditional
database-based apps could be easily converted to a blockchain -based decentralized system and
expanded to multiple organizations.
In a traditional environment, all apps must be based on the same database to store and verify the
data. With the method in this patent, th ere is no need to modify the app code, insert the BC -DB
adapter layer between the database and the blockchain in each node, and then select the fields in
the database to automatically synchronize to all other databases through the blockchain. If there
is a data conflict, the adapter resolves it. All the changes from DB1 and DB3 are synchronized to
DB2, and APP 2 could query all confirmed data.
Example 2: Supply Chain
For supply chain scenarios, there may be different participants, like part suppliers,
manufacturers, logistic companies, retailers, banks, etc. Product info data needs to be shared
between different organizations. Suppliers write records for parts supplied to the manufacturer.
Manufacturers write product information and which parts were used for which product. Logistic
companies write details regarding product transportation. Retailers write product sales
information. The bank needs all the aforementioned information to issue loans.
By adding an adapter beside each database, the databases on diff erent nodes could be
synchronized and achieve impressive results. The supply company knows the inventory of the
manufacturer. It thus could prepare parts in advance, thereby shortening the lead -time. The
logistic company could get the product data even if it is still at the manufacturer, and can arrange
vehicles in advance. The manufacturer receives the retail data to help plan the manufacturing
cycle to better suit market needs. The bank could receive all the data from the different nodes to
detect potential fraud and issue loans to participants.
