Which types of database technology are used in blockchain technology?

Blockchain technology primarily relies on decentralized databases, but it also incorporates certain traditional database principles. The main types of database technology used in blockchain include:

1. Distributed Ledger Technology (DLT)

A database that is consensually shared, synchronized, and spread across multiple sites, countries, or institutions.

Blockchain itself is a type of DLT. It ensures that all participants in the network have an identical copy of the ledger, removing the need for a centralized authority.

In the distributed ledger or digital ledger stored the records of the transaction of the from the different types of nodes are connected in the blockchain technology. The data blocks are connected through the chain as links to the subsequent blocks of data. The chain is connected to the previous blocks to make a link and each data block stores the lists of records.

2. NoSQL Databases

Non-relational databases that store data in a format other than tabular relations (i.e., unlike SQL databases).

NoSQL databases can store unstructured data, which is essential for decentralized applications (dApps). They allow for flexibility in storing blockchain transaction data.

NoSql does not use the structure query language that means there isn't any structure for storing the data in the files of NoSql database applications software.

NoSql is a distributed database system that provides the flexibility to use the database technology to provide the high performance on the business system such as:- the blockchain technology.

3. Key-Value Databases

A type of NoSQL database where data is stored as key-value pairs.

Blockchain uses key-value databases to efficiently store transaction records and ensure fast lookups.

Key value database stores the key as an unique identifier which is used for the searching and optimization quickly by the key and the value is used to store the document, string, image files etc. It is easy to identify the data and values using the key values database model in the NoSql database.

4. Graph Databases

A database designed to treat the relationships between data points as equally important to the data itself.

Blockchains with complex transaction relationships (such as decentralized social networks or supply chain platforms) may use graph databases to efficiently handle these relationships.

The graphs store the patterns that identify the spikes and the fluctuations of the graphs easily and store the values also in the graphical form. It is a pictorial representation of a database to show how the entities are connected to each other or some special entity connection. It includes the nodes and their connection from edges and mentioned with their properties.

5. Immutable Databases

Databases where data, once written, cannot be changed or deleted.

Blockchain’s core principle is immutability. Once a transaction is recorded in a block, it becomes permanent and cannot be modified, which is crucial for trust and security.

It is a fixed database model that cannot be able to change its values from the immutable database file.

It is very beneficial that cannot be removed the evidence of the lists of records that are stored in the data blocks in the blockchain database which builds a trust to secure the database to save it into the immutable database file.

6. Time-series Databases

A type of database optimized for timestamped data.

Blockchain involves recording sequences of transactions over time. Time-series databases are useful for tracking these historical transactions efficiently.

The time series database is used to stamp the time on the records to easily identify the records stored with the time stamped in the database file. It is also pure evidence to shows the record with saving at the particular time stamped on every records. The records are in the lists that is easier to understand with the time-stamped.

Each of these database types plays a unique role in ensuring blockchain’s functionality, scalability, security, and performance.

Let's discuss the points above about the computer system and blockchain database technology related to the topic of “Which types of database technology are used in blockchain technology?” explanation following below here:

The blockchain technology uses the database technology to store the data in records

1. Decentralized Ledger:

Blockchain uses a decentralized database where data is stored in blocks linked together in a chronological chain. Each block contains a set of records (transactions) and is connected to the previous block, forming a secure, immutable ledger across multiple nodes in the network.

It is a distributed ledger or decentralised ledger stored in the database that are handled by many servers which are also distributed at any place who has been participate in the blockchain technology to store the transaction of lists of records in the data blocks.

2. Immutable Data Storage:

Unlike traditional databases that allow for data modification, blockchain records are immutable. Once a transaction is recorded in a block and added to the chain, it cannot be altered or deleted, ensuring transparency and security. This is achieved through cryptographic hashing and consensus mechanisms among participants.

This data storage cannot be able to update or change once it has been stored permanently in the immutable database. It is used to build trust to store the important database which is sensitive database also for the business model. It is not allowed for any modifications on the immutable database where the immutable means the still or permanent database to store in the data blocks.

The records are connected to the chain as a link

1. Cryptographic Hash Linking:

Each block in a blockchain contains a cryptographic hash of the previous block, which acts as a unique identifier. This hash ensures that blocks are linked together in a specific order, creating a secure chain of records. If any data in a previous block is altered, the hash changes, breaking the link and alerting the network of tampering.

Cryptography language is a hidden meaning language that is encoded from the application or program to decoded from the same program to understand the cryptographic language designed from the application software for digital communications systems to protect from the third party attackers or unknown access of the user. It is used to protect the transaction of payment which included high amount of payment transaction or sensitive database.

2. Sequential Data Integrity:

The linking of blocks ensures that records are stored in a sequential, time-stamped manner. This chronological linking prevents any alteration of past records without consensus, maintaining the integrity of the entire blockchain. The structure guarantees that the history of transactions is transparent and trustworthy.

The sequential data integrity means the data can only store in the sequence that are connected to the previous block of data and connected through the chain as a link which makes a sequence of data blocks and reduces the inaccuracies on the transaction and stamped with the time through the time series database.

The distributed ledger is a digital ledger that provide the records of transaction in the blockchain

1. Shared Across Multiple Nodes:

A distributed ledger in blockchain is maintained across multiple nodes (computers) in a decentralized network. Every node holds a copy of the entire ledger, ensuring that no single entity controls the data. This decentralization enhances security and transparency, as the records are accessible to all participants in real-time.

Shared multiple nodes in the distributed database and digital ledger to access any time to any servers which are distributed who has been participated on the distributed database system to store the data blocks and connected with Linking chain for the blockchain technology.

2. Immutable Record of Transactions:

Once a transaction is recorded on the distributed ledger, it becomes permanent and cannot be altered or deleted. This immutability is ensured by cryptographic techniques, making the transaction history trustworthy. Any attempt to alter a previous record would require consensus from the majority of the network, which is highly unlikely.

The records are the evidence which is a proof of transaction of payment which is very beneficial for the users who shared sensitive information and payment to the particular nodes of servers that are distributed to different nodes and it cannot be changed or not allowed for any modifications on the records which builds a trust on immutable records of transaction.

3. Consensus Mechanism:

The accuracy and validity of transactions in the distributed ledger are maintained through consensus mechanisms like Proof of Work (PoW) or Proof of Stake (PoS). Before adding a new block of transactions to the ledger, network participants must agree that the transaction is valid, ensuring the integrity and reliability of the blockchain.

The accuracy of data is applied which is a part of data integrity and the validation is also a part of data integrity of transaction which describes that the data is accurate, complete or not incomplete or lack of information etc. Stored in the lists of records in the digital ledger. The validity means the time of data is valid for values store otherwise the data will be removed when the validity of data is completed at the particular time.

Every records are stored in the blocks of memory

1. Data Stored in Blocks:

In blockchain technology, records (such as transaction data) are grouped into blocks. Each block has a fixed size limit, and once it reaches capacity, it is sealed and added to the chain. The data within the block typically includes details like transaction timestamps, sender and receiver information, and the transaction amount.

Data stored into the data blocks which is equally distributed in the memory size of file if the file is stored into the two blocks then the file will broken into two parts of data blocks to stores in the data blocks. It is fast to access and retrieve the data from the equally distributed data blocks and divided into equally parts.

2. Block Structure:

A block consists of two main components: the header and the body. The header contains metadata such as the hash of the previous block, the block number, and a unique identifier (hash) for the current block. The body contains the actual list of transactions or records being stored.

The unique identifier is used to access the information of the body which contains the values of the key. The key values database is fast to access the information of the record where the records included the transaction information of the users and nodes as a servers of database distributed many participants in the blockchain system.

3. Cryptographic Security:

Each block is secured using cryptographic hashing, ensuring that the records within the block cannot be altered without changing the entire blockchain. Any change in the data would create a mismatch in the hash values, breaking the integrity of the blockchain.

Cryptography language is a system that encoded values is only decoded by the application program which is separately distributed for the many servers and computers nodes that are participating in the blockchain technology for maintaining the transaction of the users and computers. It cannot be hacked because it is a hidden language that cannot be decoded by the attackers.

4. Permanent and Linked:

Once a block is filled with records and added to the blockchain, it becomes part of an immutable, permanent ledger. This block is linked to the previous block through its hash, creating a chronological, unchangeable chain of records. This ensures that the history of all transactions remains transparent and secure.

The permanent database is a still database once a data has been stored into the digital ledger or data blocks in the form of the lists of records then the records are not vable to update, delete or change because it is an immutable database file. It is finally and permanently stored in the data blocks of the distributed database for the digital ledger technology in the blockchain technology for the secured transactions.

Basically the distributed database technology is used to provide blockchain technology which protects from the unknown attackers

1. Decentralization for Security:

Blockchain technology relies on a distributed database where data is not stored in a single location but across multiple nodes in a network. This decentralized nature ensures that no single point of failure exists, making it extremely difficult for attackers to compromise the system, as they would need to control the majority of the nodes.

It is a distributed database system that follows by the several servers that are maintained by the users of their servers who has been participated in the blockchain system. The Decentralized system means the distributed database models is used in the decentralized model of the blockchain system. It is distributed which means the attackers cannot be able to have any target database servers.

2. Consensus Mechanisms:

Blockchain uses consensus mechanisms such as Proof of Work (PoW) or Proof of Stake (PoS) to validate transactions. These mechanisms require the agreement of most network participants before a new block can be added to the chain, preventing malicious actors from altering or forging records without network-wide approval.

Suppose the users has been paid to the particular item for online shopping in the online transaction that is recorded in the lists and saved into the data blocks. These data and information is valid when the user terms and conditions applied on their database if the user closed their account then the database will be remove which is not at the particular time period completed such as:- a time validity of data is completed after 2 years of the users transactions of record in the data blocks then the lists of records cannot be valid and it will removed after completing a validation.

3. Cryptographic Protection:

Blockchain employs cryptographic algorithms to secure data. Each block is cryptographically linked to the previous block using a unique hash. This ensures that even if an attacker were to modify data in one block, the hash of that block would change, disrupting the chain and making it easy to detect the tampering.

For example:- the cryptography language is encoded in the form of the ‘abcd’ is a type of encoded data sent to the server which is distributed and the same application software is used to decoded that data sent from the previous server then the cryptography language is a protected from the unknown access the information during the sending the data which encoded form of the data or cypher text in the cryptographic techniques. In this method the attackers cannot be understood that information which is sending to the server.

4. Immutability of Data:

Once data is recorded in a block and added to the blockchain, it cannot be changed or deleted. This immutability ensures that historical records remain intact and cannot be altered by attackers. Any attempts to alter previous records would be immediately noticed by the entire network.

The user create a transaction of money or sensitive data then the data has been used as an evidence of the user of transactions. It is immutable database which cannot be able to removed, modify, changed or update. It is only readable and accessible by the privilege or users who has been create a transaction between two servers distributed in the network. The immutable database means the data cannot be changed if the validity is not completed, but if the validity has been completed then the data will removed as per term and condition designed by the company for the users.

5. Distributed Validation:

In a distributed blockchain network, every node holds a complete copy of the ledger. Attackers would need to simultaneously attack or corrupt a majority of the nodes to successfully alter any data, which is virtually impossible in large, well-distributed blockchain networks. This provides additional protection against unknown attackers.

Attackers cannot be attack on the several servers because the data has been distributed with the immutable database. The digital ledger full of copy is distributed to many servers which can be retrieved if it is want to retrieve and access the particular key-values data from the key-values database model.
