Proof of Activity

Combine Proof of Work component with a Proof of Stake.

algorithm

Mining first begins in the traditional manner, with miners vying to be the first to solve a puzzle and claim their reward.
The difference is that the blocks being mined do not contain transactions.
They are simply templates with header information and the mining reward address.
Once this nearly blank block is mined, the system switches to a proof of stake protocol.
The header information is used to select a random group of validators to sign the block.
These are coin holders (stakeholders) and the larger the stake a validator holds, the greater the chance they will be selected to sign the new block.
Once all the chosen validators sign the block it becomes an actual part of the blockchain.
If the block remains unsigned by some of the chosen validators after a given time, it is discarded as incomplete and the next winning block is used.
Validators are once again chosen and this continues until a winning block is signed by all the chosen validators.
The network fees are split between the winning miner and the validators who signed the block.
