In 2011, Sunny King built a Bitcoin research team to study Bitcoin replacement technology.
In 2012, Sunny King released Peercoin, the first blockchain project based on the PoS consensus mechanism.
In 2012, Sunny King registered his bitcointalk account and published 1,203 posts. Most of them were Peercoin updates and technology related topics.
In 2012, Sunny King first proposed that Bitcoin was comparable to gold.
In 2013, Sunny King created Primecoin, which utilized the energy wasted by the untargeted computation in cryptocurrency. PoW mechanism in Primecoin has a certain scientific value, and miners have also contributed to Prime searching while mining.
In 2013, Sunny King was interviewed by Vitalik Buterin forBitcoin Magazine (who then founded Ethereum).
In 2014, Peercoin was ranked the third in the global cryptocurrency market, following Bitcoin and Litecoin.

On January 24th, 2018, after a year of hiding, Sunny King officially announced his new project V SYSTEMS.
In September 2018, Sunny King introduced a new consensus mechanism, Supernode Proof-of-Stake (SPoS) in V SYSTEMS project. SPoS is required to run on special hardware. King explained that SPoS is somewhat similar to DPoS, but is expected to further simplify the development and maintenance of blockchain. SPoS will work smoothly with optimized hardware. The special hardware is similar to the ASIC miner in PoW, but unlike ASIC miners, it is less energy-consuming. King has also designed a portal to ensure the network security. And while it appears that the system is more centralized, the portal could keep equal decision power distribution to every Supernode and therefore prevent certain node from being overpowered.
