Like Satoshi Nakamoto there is another legendary anonymous figure in the cryptosphere: Sunny King. He is the famous developer that first tried to challenge the proof of work (POW) mining mechanism that dominated all blockchains until then. He wanted and still wants to make the blockchain more energy efficient. The solution: Proof of Stake.

It is even said that Vitalik Buterin was impressed with the concept and it made him think of changing Ethereum from POW to Proof of Stake (PoS) in the future. Buterin co-wrote a paper called “Casper” covering the topic.

Proof of stake is widely adopted nowadays and some blockchains even use a combination of both POW and PoS. PoS masternodes are very popular because they can be run on a VPS and don’t require sophisticated dedicated hardware or ASICs like POW mining does.

Sunny King developed two projects in the past that might get attention now that he is back in the cryptosphere. I want to cover Sunny Kings projects and give an outlook on what he is up to next in this short summary.
