What's inside

Proof of Stake (PoS)

Research Papers

Proof of Work (PoW)

  • Bitcoin (BTC)

    The first and most popular blockchain network using Proof of Work.

  • Ethereum (Pre-2.0)

    Originally used PoW before transitioning to PoS with Ethereum 2.0.

  • Hashcash

    The original PoW algorithm, used as a defense against spam and DDoS attacks.

  • Litecoin (LTC)

    A cryptocurrency using a variation of PoW called Scrypt, aimed at reducing centralization.

  • Proof of Work Explained

    A detailed explanation of the Proof of Work consensus mechanism.

Educational Resources

General Resources

Directed Acyclic Graph (DAG) Consensus

  • DAG Consensus Explained

    An overview of DAG-based consensus algorithms.

  • Hedera Hashgraph

    Uses a DAG consensus mechanism called Hashgraph for fast and secure transactions.

  • IOTA (MIOTA)

    Uses a DAG-based consensus model called the Tangle.

  • Nano (NANO)

    Uses a block-lattice structure with DAG consensus for instant transactions.

Hybrid Consensus Mechanisms

  • Decred (DCR)

    Uses a hybrid consensus mechanism combining PoW and PoS.

  • Harmony (ONE)

    Uses a hybrid PoS and BFT consensus model for scalability.

  • Zenon (ZNN)

    Combines PoW and PoS in a hybrid consensus approach.
