The “Basic Principles of the Blockchain Database Concept” session provides a solid foundation and context that will undoubtedly be beneficial as you progress in your understanding of blockchain technology. Blockchain technology has revolutionized various aspects of society, economy, and governance. It offers a paradigm shift that can transform the way we store and manage data. In this presentation, we will look into the fundamental principles of blockchain databases, their key characteristics, and different deployment options. We will also explore the challenges involved in building blockchain databases and discuss some popular blockchain-based database solutions.
What is a Blockchain Database?
A blockchain database is a specialized type of database that utilizes blockchain technology to store and manage data. It combines the advantages of traditional databases with the immutability, transparency, and decentralization provided by blockchain.
In a blockchain database, data is organized into blocks that are interconnected using cryptographic hashes, creating a chain-like structure. Each block contains a batch of transactions or data entries, which, once added to the blockchain, become permanent and tamper-proof records.
Unlike traditional databases, where a central authority or administrator controls access and manages the data, blockchain databases are decentralized. They are typically maintained by a network of participants or nodes, who collectively validate and record transactions through consensus mechanisms.
Blockchain Database Deployment Options
When considering blockchain database deployment, several factors come into play. Two significant factors to consider are whether the database will be used within an enterprise or consortium and how the data will be used. Based on these factors, four possible ways to create a blockchain database emerge:
1. Centralized With Operational Data/Operational Blockchain Data Store With Enterprise
In this scenario, the blockchain database is deployed inside an enterprise. It does not require decentralization, simplifying the deployment process while leveraging the advantages of blockchain over traditional databases. The database can be used for decision-making and operational reporting, offering immutability and asset creation and transfer capabilities.
2. Centralized With Non-operational Data/Non-operational Blockchain Data Store With Enterprise
Similar to the previous scenario, this deployment is centralized within an enterprise. However, intermediaries are set up to access the data store and deliver it to clients. This approach offers better performance and privacy as the data is only accessible to a limited number of clients.
3. Decentralized With Operational Data/Operational Blockchain Data Store With Consortium
In this scenario, a consortium is formed to remove the need for a single entity to control the database. Each company within the consortium acts as an individual node responsible for maintaining the database. This decentralized approach increases data immutability and is suitable for applications like supply chain management.
4. Decentralized With Non-operational Data/Non-operational Data Store With Consortium
Multiple administrators from different consortium members control the blockchain in this scenario. Intermediaries facilitate client access to the data in the database, offering increased speed and privacy. This approach is useful for companies holding sensitive information that should be accessible only to authorized parties.
In conclusion, blockchain databases present a paradigm shift in the way we store and manage data. By combining the advantages of traditional databases with the immutability and decentralization of blockchain, they offer enhanced security, transparency, and reliability. However, challenges related to querying capabilities, scalability, throughput, and latency need to be addressed to fully utilize the potential of blockchain databases. Various blockchain-based database solutions like BigchainDB, Cassandra, ChainifyDB, Modex BCDB, and Postchain are available, each with its unique features and benefits.
As I rightly said at the end of the presentation, “Blockchain databases bring the concept one step further and combine the best of both worlds.” With ongoing advancements and innovations, the future of blockchain databases looks promising in transforming industries across the globe.
This video is part of a consultation session on “Technical Expert Service on Improvement of Public Sector Efficiency Using Blockchain-based Database”. The implementing organizations include the Ministry of Industry and Technology of Turkiye and the Asian Productivity Organization. The event was held in Ankara and Bolu, Turkiye, from 4–7 July 2023.
