Proof of Participation

The Proof of Participation consensus equally distributes decision power and rewards amongst every node contributing to a blockchain’s operation. This approach removes the link between decision power and resources.

Proof of Capacity

Similar to Proof of Work but instead of computing resources, Proof of Capacity leverages available disk space (storage).

Proof of Reputation

Do you know the consensus mechanism whose reputation of a node is constructed based on its asset, transaction activity, and consensus participation?

Proof of Authority

Born within Ethereum’s dev team, Proof of Authority consensus algorithm is based on a reputation of block validators and puts it at stake.

Delegated Proof of Stake

Delegated Proof of Stake can be thought of as representative democracy. Token holders vote on a representative who then validates the network for them. DPoS chains have fewer validators what increases efficacy at the cost of increased centralization.

Proof of Stake

Proof of Stake consensus mechanism, as one of the most common alternatives to Proof of Work, provides a slight improvement to scalability but leads to a “rich get richer” economic paradigm. In POS-based Blockchains, nodes process and validate transactions by proving that they have ownership of a certain amount of the asset, rather than by …

Proof of Work

Some tech experts believe that Proof of Work is a technological dead-end, while others think that you cannot have a blockchain without this consensus algorithm. What is your perspective? Is Proof of Work dead?
