Blockchain Technology: How Cryptocurrencies Work

Blockchain technology underpins many cryptocurrencies, serving as a secure and transparent ledger for recording transactions. It’s a distributed, immutable database that maintains a continuously growing list of records, called blocks, which are chained together chronologically. This decentralized structure, resistant to single points of failure, makes it highly resilient and attractive for digital asset management.

Structure and Function of a Blockchain

A blockchain is a sequential chain of blocks. Each block contains a set of transactions, a timestamp, and a cryptographic hash of the previous block. This cryptographic link creates an immutable record, as altering a single block would necessitate changing all subsequent blocks, requiring an enormous computational effort. The structure enables a shared, auditable record of all transactions, making it transparent and verifiable by all participants.

How Transactions are Recorded and Verified

Transactions are grouped into blocks. Each transaction includes details like sender, recipient, and amount. These transactions are then cryptographically hashed and added to the block. The block’s hash is linked to the previous block’s hash, creating the chain. This cryptographic linking ensures the integrity of the data.

Verification involves consensus mechanisms, as described later, to validate the transactions and add the block to the chain.

Consensus Protocols

Consensus protocols are essential for achieving agreement among participants on the validity of transactions and the addition of new blocks. Different protocols employ various approaches to achieve consensus.

• Proof-of-Work (PoW): This protocol requires computational power to solve complex mathematical problems. Miners compete to solve these problems, and the first to do so adds the new block to the chain, earning rewards. Bitcoin utilizes PoW. Example: Imagine a complex puzzle. The miner who solves it first gets to add the next block to the blockchain and earns a reward.

• Proof-of-Stake (PoS): In PoS, validators are selected based on the amount of cryptocurrency they hold. Those with more stake have a higher chance of being selected to add the next block. This method reduces the energy consumption compared to PoW. Example: Think of a lottery where participants with more tickets have a higher chance of winning.

  The winner adds the block.

Security and Immutability

The decentralized nature of a blockchain and the cryptographic hashing mechanism contribute significantly to its security. Each block’s hash is linked to the previous one, creating a chain. Altering a block requires changing all subsequent blocks, which is computationally infeasible. The distributed nature of the ledger means that no single entity controls the data. This distributed nature and cryptographic hashing make blockchain exceptionally resistant to tampering and fraud.
