Blockchain is a revolutionary database technology at the heart of almost all cryptocurrencies. By distributing identical copies of the database throughout the network, blockchain makes it extremely difficult to hack or cheat the system. Cryptocurrencies are currently the most common use of blockchain, but the technology offers the potential to serve a very wide range of applications.
What is Blockchain?
At its core, a blockchain is a distributed digital ledger that stores all kinds of data. Blockchains can record information about cryptocurrency transactions, NFT ownership, or DeFi smart contracts.
Traditional databases can store this kind of information, but blockchain is unique in that it is completely decentralized. Instead of having a central administrator maintain it in one place (think Excel spreadsheets or bank databases), many identical copies of the blockchain database are stored on multiple computers distributed throughout the network. will be These individual computers are called nodes.
Why Blockchain Matters:
Businesses are made of information. The faster and more accurate the reception, the better the results. Blockchain is ideal for providing this information as it provides instant, shared and completely transparent information stored in an immutable ledger that can only be accessed by authorized network members. Blockchain networks can track orders, payments, accounts, production, and more. And because members share a unified view of truth, they can see every transaction detail from start to finish, resulting in greater confidence, new efficiencies, and opportunities.
Key Elements of Blockchain
Distributed Ledger Technology
All network participants have access to a distributed ledger and an immutable record of its transactions. With this shared ledger, transactions are recorded only once, eliminating the duplication of effort common in traditional business networks.
Immutable Recording
After a transaction is recorded on the common ledger, participants cannot modify or tamper with it. If your transaction record contains an error, you will need to add a new transaction to undo the error. Both transactions are then displayed.
Smart Contracts
To speed up transactions, a set of rules called smart contracts are stored on the blockchain and automatically executed. A smart contract can define the terms of a bond transfer or include the terms of payable travel insurance.
How Blockchain Works
Each transaction is recorded as a 'block of data'
These transactions represent the movement of tangible (product) or intangible (intellectual) assets. Data blocks can record selected information:
who, what, when, where, how much, and even the status of food shipments such as temperature.
Each block is connected to the block before and after. These blocks form a data chain as assets move from one place to another or change ownership. Blocks ensure the exact timing and order of transactions, and blocks are safely combined to prevent modification of blocks or insertion of blocks between two existing blocks.
Transactions are blocked together in an irreversible chain. This prevents the blockchain from being tampered with and provides the key strength of immutability. This eliminates the possibility of tampering by malicious actors and creates a ledger of transactions that you and other network members can trust.
Blockchain Benefits
What Should Change:
Operations often waste effort with duplicate records and third-party verification. Systems of record can be vulnerable to fraud and cyberattacks. Limited visibility can slow down data validation. And with the advent of IoT, transaction volumes have exploded. All of this slows down your business and eats into your bottom line. In other words, we need a better way. Enter the blockchain.
Greater Trust
Blockchain allows you, as a member of a member-only network, to receive accurate and timely data, and confidential blockchain records are shared only with network members who explicitly consent to access. increase.
Greater Security
Requires agreement on data accuracy from all network members and is immutable as all verified transactions are permanently recorded. Transactions cannot be deleted, even by system administrators.
Greater Efficiency A distributed ledger shared among members of the network eliminates the need for time-consuming reconciliation of records. And to speed up transactions, sets of rules called smart contracts can be stored on the blockchain and executed automatically.
Types of Blockchain Networks
There are several ways to build a blockchain network. They may be public, private, concessional, or established by consortium.
Public Blockchain Network
Public Blockchain is a blockchain that anyone can join. Bitcoin for example. Disadvantages include significant computational power requirements, little or no transaction privacy, and weak security. These are important considerations for blockchain enterprise use cases.
Private Blockchain Networks Private blockchain networks, similar to public blockchain networks, are decentralized peer-to-peer networks. However, one organization manages the network, controls who can participate, runs the consensus protocol, and maintains the common ledger. Depending on the application, it can greatly enhance trust between participants. Private blockchains can run behind corporate firewalls and can be hosted locally.
Permissioned Blockchain Networks
Companies that set up private blockchains typically set up permissioned blockchain networks. It's important to note that public blockchain networks may also be allowed. This limits who can participate in the network and what transactions they can participate in. Participants must receive an invitation or permission to participate.
Consortium Blockchain
Multiple organizations can share responsibility for maintaining a blockchain. These preselected organizations determine who can submit transactions and access data. Consortium blockchains are ideal for businesses when all participants require endorsement and shared ownership of the blockchain.
Blockchain Security
Blockchain Network Risk Management System
A comprehensive security framework that uses cybersecurity frameworks, assurance services, and best practices to manage and mitigate the risk of attacks and fraud when building enterprise blockchain applications. Having a security strategy in place is important.
Evolution of Blockchain
The first blockchain concept dates back to 1991, when Stuart Haber and Wakefield Scott Stornetta proposed the idea of a cryptographically protected chain of records or blocks. Twenty years later, the technology has gained momentum and is widely applied. 2008 marked a turning point for blockchain when Satoshi Nakamoto gave blockchain technology an established model and intended application. The first blockchain and cryptocurrencies, officially launched in 2009, began the path of blockchain's impact on the entire technology sector.
