Proof of Activity is a hybrid consensus algorithm that combines the Proof of Work and Proof of Stake mechanisms to increase the security and resilience of the network.

Proof-of-Burn is a consensus algorithm in which a participant irreversibly destroys a portion of coins in order to earn the right to create blocks and claim a reward in the network.

Proof of Capacity is a consensus algorithm in which miners use free space on storage drives instead of energy-intensive computations, which makes mining coins cheaper and more environmentally friendly.

Proof of Importance is a consensus algorithm that takes into account not only the size of the balance but also a participant's activity in the network when distributing the right to create blocks.

Proof-of-Storage is a mechanism in which participants provide disk space for shared data, and the network confirms that the files are indeed reliably stored.
