1. Transaction Initiation
A cryptocurrency transaction begins when a user requests to transfer an asset (e.g., Bitcoin) to another user. This request is broadcasted to the network for validation.
2. Validation Process
The transaction details are sent to a network of decentralized nodes (computers). These nodes validate the transaction based on set protocols, ensuring the sender has enough balance and that the transaction follows the blockchain rules.
3. Creation of a New Block
Once verified, the transaction is grouped with others to form a block. Each block contains:
- A list of verified transactions
- A timestamp
- A cryptographic hash of the previous block
- A unique hash for the current block
4. Consensus Mechanism
The network must agree on the validity of the new block through a process called consensus. The most common consensus mechanisms include:
- Proof of Work (PoW): Miners compete to solve complex mathematical puzzles. The first to solve it adds the block to the chain and receives a reward.
- Proof of Stake (PoS): Validators are chosen based on the amount of cryptocurrency they hold and are willing to “stake” as collateral. This mechanism is more energy-efficient than PoW.
5. Adding the Block to the Chain
Once a block is validated and consensus is reached, it is added to the existing blockchain. The new block’s cryptographic hash links it to the previous block, ensuring a tamper-proof record.
6. Distribution Across the Network
The updated blockchain is distributed to all nodes, ensuring that every participant has an up-to-date copy of the ledger. This prevents any single entity from making unauthorized changes to the blockchain.

The Technical Underpinnings of Blockchain
To truly appreciate the power of blockchain, it’s important to understand some of its technical aspects:
1. Hashing Algorithms
Hashing is a process that takes an input (or “message”) and returns a fixed-length string of characters, which appears random. Each block in a blockchain has its own hash, which is influenced by the hash of the previous block. This creates a chain reaction that enhances security: altering one block would require recalculating all subsequent block hashes, a virtually impossible task on a large network.
Example: Bitcoin uses the SHA-256 hashing algorithm, which outputs a 256-bit signature for each block, making it highly secure.
2. Consensus Mechanisms
The consensus mechanism is what ensures that all nodes in a network agree on the validity of transactions. Here’s a deeper look at some common types:
- Proof of Work (PoW): The original consensus mechanism used by Bitcoin. Miners compete to solve complex mathematical problems, which requires significant computational power. This ensures security but is energy-intensive.
- Proof of Stake (PoS): Used by newer blockchains like Ethereum 2.0, PoS selects validators based on the number of tokens they hold and are willing to “stake.” This reduces energy consumption and makes the network more sustainable.
- Delegated Proof of Stake (DPoS): An evolution of PoS where token holders vote for a small number of delegates who create and validate new blocks. This speeds up the network while maintaining decentralization
