Proof of Commitment (PoC+)

The smart solution for a sustainable blockchain.

What makes Signum truly sustainable?

Bitcoin's infamous Proof of Work consensus protocol requires expensive, specialized, energy-hungry hardware. This results in the enormous amount of 121 TWh of energy consumption per year and more than 9 kilotons of e-waste. By using consumer-grade hardware that is easily re-purposed Signum also avoids e-waste and in comparison, requires less than 0.002% of that energy to drive the Blockchain.

On Signum, energy-intensive calculations are done only once when the miners plot their available disk space. Thereafter the mining process requires reading through a very small fraction of this disk space (1/4096, less than 0.025 % of the plotted capacity). The hard disks are idle most of the time as this small fraction only needs to be read every few minutes to secure the network.

Signum truly sustainable

Signum is truly sustainable.
It uses consumer-grade hardware that can easily be repurposed (no e-waste) and it uses hardly any energy to secure the network.

A game-changer for the crypto sector

What is PoC+?

Signum introduced the world to the Proof of Commitment (PoC+) decentralized consensus as the evolution of the Proof of Capacity (PoC) consensus. 

Different than the well-known Proof of Work (PoW) consensus used by Bitcoin and many other coins, which require special power-hungry equipment, PoC+ simply uses available disk space.

This innovative consensus offers a new way for miners to increase their effective storage capacity - committing a Signa balance (stake) in their account. This will help secure the network and improve their chances of earning mining rewards. PoC+ is a greener option since effective capacity can be increased without purchasing more equipment.

The mining process in the PoC+ consensus is so effective and has such low hardware requirements that any consumer-grade PC can be used to mine.  The user will not even notice that the mining process is happening, aside from the occasional blinking LEDs from the hard disk drive (HDD)!

No Limits

No limits

Signa can be mined with PCs, tiny computers like a Raspberry Pi, or even mobile phones (even old ones). The only thing needed is disk space to create what are known as plot files. With its PoC+ algorithm, Signum opens up the possibility for everyone to participate in the mining process without any major obstacles.

Empowering People
