LEOcoin intends to move from a Proof of Work (POW)/Proof of Stake (POS) to a solely POS mechanism. In this regard, I will today post the first of a three updates to shed some more light on the reasons, motivations and timing. The source is the last lecture of Mr. Sohail Ramzan on Bali. I have summarized this and will state it as it is for your information only and not further discuss the contents of his presentation.

Part one:
Regarding the next step from POW/POS to a 100% POS mechanism; there are quite some points that speak in favour of this:
1. Lower electricity costs
- POW: Mining LEOcoins with mining RIGs consumes a lot of energy, both for the computations of the CPU/GPU as for cooling the devices with extra fans and air-conditioning. Most of this energy is wasted as all RIGs perform the same cryptographic calculations, but only one RIG per block is rewarded with 20 LEOcoins (or the pool is where each RIG is awarded conform their shares in the pool’s round).
POS: The POS mechanism requires no additional electricity; you only have to open your LEOcoin wallet and stake in an easy and safe way.
- POW: Mining is hard on your hardware and it reduces your hardware’s life cycle. A decent GPU will cost you about 300$ and a RIG will take several of these! Also additional memory might have to be installed when the n-factor goes up. Used hardware loses its market value extremely fast because of new and faster performing update-models. Next to energy, hardware and maintenance are the main cost factors.
POS: There is no significant impact on your computer’s lifespan because only very little computation is done when staking. Nor do you need a very fast pc to stake LEOcoin.
- POW: Pay-out become less rewarding due to increase in difficulty (n-factor increase)
POS: Reward is based on the LEOcoins held in your wallet(s).
- POW: Prone to compute-power centralization.
POS: Every LEOcoin that you own, has a chance to earn more LEOcoin.
- POW: Prone to malware taking advantage.
POS: Botnets can’t leverage computers to mine a Proof of Stake LEOcoin.
