A blockchain is actually a database because it is a digital ledger that stores information in data structures called blocks However, while a blockchain is a database, a database is not a blockchain They are not interchangeable in a sense thatExecutive view A blockchain is a shared decentralized ledger, enabling business disintermediation and trustless interactions, thereby lowering transaction costs 2 The IT architect and data management view A blockchain is a shared appendonly distributed database with full replication and a cryptographic transaction permissioning model 3 · Blockchain data structure The blockchain data structure is an ordered, backlinked list of blocks of transactions The blockchain can be stored as a flat file, or in a simple database The Bitcoin Core client stores the blockchain metadata using Google's LevelDB database Blocks are linked "back," each referring to the previous block in the chain

A blockchain is a database or a ledger that stores information in a data structure called blocks It is based on distributed ledger technology which can be used between parties that don't trust each other with data It is because when you add anything onto the blockchain, it requires verification from all other users available on the network1604 · Blockchain vs Database Comparison Blockchain vs Database Architecture Considering the architecture, both blockchain and database structure are much different Blockchain uses a distributed ledger network architecture It is a peertopeer enabled network Each peer connects with another using secure cryptographic protocols · The blockchain is a chain of blocks which conta i n specific information (database), but in a secure and genuine way that is grouped together in a network (peertopeer) In other words, blockchain is a combination of computers linked to each other instead of a central server, meaning that the whole network is decentralized
Database System Concepts 7th Edition 266 ©Silberschatz, Korth and Sudarshan Blockchain Properties and Structure Node types • Full node – maintains copy of blockchain and participates in the consensus process • Light node – submits updates to the blockchain but does not participate in the consensus process Consensus algorithms to choose node to add next block0506 · You can define data structures within the smart contracts, essentially turning the blockchain into a database You can build a permissions capability into smart contracts – essentially baking your security model into the blockchain itself in a way that cannot be modified without majority consensus You can define workflow for a number ofBlockchain Data Structure/ Merkle Tree 23 Bl o c k c h a i n T e c h n o l o g y S ta c k 2 5 Shared Data 26 Protocols 26 Although many people like to understand blockchain as a database, It is much more than a database It is a combination of distributed or shared databases with public or
Despite its apparent complexity, a blockchain is just another type of database for recording transactions – one that is copied to all of the computers in a participating network A blockchain is thus sometimes referred to as a 'distributed ledger' Data in a blockchain is stored in fixed structures called 'blocks' · Using the same cryptographic patterns seen in blockchain technology, each transaction is cryptographically hashed and inserted in a blockchain data structure The computed hashes of your database are then stored outside of Azure SQL Database in tamperproof storage (such as Azure immutable Blob storage , or Azure Confidential Ledger ), as database digests · Unlike traditional databases, Blockchain which was introduced in 09 by Satoshi Nakamoto is a peertopeer decentralized distributed ledger consisting of multiple nodes with replicated data that cannot be changed It is an appendonly database that is

· The discussion around the blockchain and traditional databases has been active for a long time The main question is which of the two different systems is better?The blockchain in itself is a data structure that stores transactions It is similar to a linked list in that the data is split into containers the blocks Each block is connected with its predecessor with a cryptographically secured reference This makes the data structure tamperevident, changes to old blocks are easy to detect and dismissed · Broadly speaking, blockchain data structure can be described as a back linked list of transaction, arranged in blocks They can be stored in simple databases or in the form of flat files Each block is identified with the help of hash in the block header

Ing blockchain storage and count on trusted database servers for query integrity assurance In contrast, our proposed vChain solution builds authenticated data structures into the blockchain structure, so that even untrusted servers can queries over blockchain databases · Its appendonly structure only allows data to be added to the database altering or deleting previously entered data on earlier blocks is impossible Blockchain technology is therefore wellsuited for recording events, managing records, · You can establish data structures inside the intelligent contracts, practically covering the blockchain into a blockchain database You can create a permissions capability into intelligent contracts – practically embedding your security model within the blockchain database structure so that it can't be changed unless approved by a consensus

· Blockchain tables provide stronger database security by protecting against user fraud where someone rewrites their history, deletes certain data, or encrypts it for ransom It can also provide identity fraud protection – the optional signing of row data with the PKI signatures based on the user's private key protects against users or admins · Blockchain is a type of database, but it is quite different from a traditional database, and one of the biggest differences is its storage structure Blockchain stores data in numerous groups termed blocks Each block has a lot of information, but the space in them is limited0412 · You might think blockchain as a database that just stores information However, the difference is immense In reality, both of them are quite different, and we'll get into that shortly in the blockchain vs relational database comparison Blockchain is, by default, immutable So, it means that no one can modify any form of data whatsoever

0519 · As blockchain is a ledger that stores information in blocks, it actually makes it a database A database in the same way stores information in data structures named tables Nevertheless, a blockchain is a database, but a database is not a blockchain Both these structures should never be interchanged as both of them serve a different purposeA distributed database is also a decentralised data structure which features quick query processing and welldesigned data formatting but suffers from data reliability In this work, we showcase ChainSQL, an opensource system developed by integrating the blockchain with the database, ie we present a blockchain database application platformOne way to define a blockchain is a distributed database (DB) that solves the "Strong Byzantine Generals" (SBG) problem, the name given to a combination of the Byzan tine Generals Problem and the Sybil Attack Problem
