Distributed Ledger Technology (DLT)

• Blockchain is built upon a distributed ledger, a decentralized database that stores transaction records across multiple network nodes (computers).
• Each node in the network has a copy of the entire blockchain, ensuring that all participants share the same transaction history.
• This distributed nature enhances transparency, security, and immutability, as altering a single transaction requires the consensus of most nodes.

Transactions and Blocks

• Transactions represent the exchange of assets, currencies, or data on the blockchain.
• Multiple transactions are grouped in a block, forming a unit of data.
• Before being added to the blockchain, a block must undergo verification and validation.

Consensus Mechanisms

• Blockchain networks use consensus mechanisms to ensure that all participants agree on the validity of transactions and the order of blocks.
• Common consensus algorithms include Proof of Work (PoW) and Proof of Stake (PoS).
• In PoW, nodes compete to solve complex mathematical puzzles to validate and add blocks to the blockchain. The first node to solve the mystery is rewarded, earning the right to add the block.
• In PoS, validators are selected based on the number of coins they hold and are willing to “stake” as collateral. Validators are chosen to add blocks based on their stake and other factors.

Mining and Validation

• In PoW-based blockchains (like Bitcoin), the process of solving complex puzzles to validate transactions and add blocks is known as mining.
• Miners use computational power to solve these puzzles, which consumes energy and resources. Successful miners are rewarded with cryptocurrency for their efforts.
• In PoS-based blockchains (like Ethereum’s planned shift to Ethereum 2.0), validators, also known as “forgers” or “bonded stakeholders,” are responsible for validating transactions and creating new blocks. They are incentivized through rewards based on their stake.

Smart Contracts

• Smart contracts are self-executing contracts with predefined rules and conditions written in code. Once the requirements are met, the contract executes automatically without intermediaries.
• In fintech, smart contracts facilitate financial agreements, such as payments, insurance claims, or trade settlements, providing transparency, efficiency, and accuracy.

Security and Immutability

• Blockchain achieves security through cryptographic techniques that encrypt and secure data within each block.
• Immutability refers to the inability to alter or delete recorded transactions, making the blockchain an unchangeable and tamper-resistant record.

By leveraging these foundational elements, blockchain technology in fintech enables secure, transparent, and efficient financial transactions, making it an essential tool in reshaping the financial industry.
