Consensus Algorithms
Discover how blockchain networks agree on a single truth, ensuring trust and security without a central authority.
What is a Consensus Algorithm?
Imagine a group of friends deciding where to eat. They vote and agree on one restaurant. A consensus algorithm is like that vote—it helps blockchain computers (nodes) agree on the same transaction history, even if some try to cheat.
It’s the rulebook for trust in a decentralized network, ensuring everyone has the same copy of the blockchain.
Key Aspects
Proof-of-Work
Nodes compete to solve a math puzzle. The winner adds a block and gets a reward. It’s secure but uses lots of energy.
Example: BinaryChain uses Proof-of-Work to validate blocks on the Mining page.
Proof-of-Stake
Nodes are chosen to add blocks based on how much cryptocurrency they “stake.” It’s faster and eco-friendly.
Example: Some blockchains use Proof-of-Stake for quicker transactions.
Fault Tolerance
Consensus algorithms handle dishonest nodes, ensuring the network stays reliable even if some nodes fail or lie.
Example: BinaryChain’s consensus prevents fake transactions from being added.
How It Works in Blockchain
In BinaryChain, consensus algorithms keep the network honest:
- Agreement: All nodes agree on valid transactions and blocks.
- Security: Prevents double-spending by ensuring one true blockchain.
- Decentralization: No single node controls the network.
