VB.co has already opened the “POC+” trading area, the first digital currencies included in the “POC+” trading zone are SARA, SPOK, NEWBI, CCX.
The trading pairs of SARA/SPOK/NEWBI/CCX in the USDT trading area will be transferred to the “POC+” trading area at the same time.
About “POC+” trading area
The “POC+”trading area is designed to provide users with high-quality POC mining projects with potential in the world. The digital assets of the trading segment are mainly based on POC and POW as a consensus mechanism. They have great development potential and are suitable for long-term holding. Compared with most ERC20-based TOKEN, their degree of community are higher, degree of centralization are lower, and the transaction risk assumed by users are more controllable.
The full name of POC is “Prove of Capacity”. It makes use of the free space of computer hard disk for storage to mine and gain the revenue, the bigger of hard space, the more storage as well as the more reward. Compared with consensus mechanisms such as POW and POS, POC not only retains the decentralization consensus, but also has the advantages of ultra-low power dependence, reduced trust cost, greater consensus strength and breadth. At the same time, the relationship between miners and hardware manufacturers is equal. It has a strong extensibility and can absorb enterprises、capital、and manpower of the traditional world to join the ecology. In summary, the advantage of PoC is that the mining threshold is lower, the degree of decentralization is higher, the consensus is stronger, and the energy consumption is smaller.
The full name of POW is “Proof of Work”, it is a proof that a certain amount of work has been done. Take Bitcoin as an example: Bitcoin uses this mechanism in the generation of Block. Finding a reasonable Block Hash requires a large amount of attempt to calculate. The calculation time depends on the hashing speed of the machine. Any node in the Bitcoin network want to generate a new block and write it to the blockchain, has to solve the puzzle of pow in the Bitcoin network. Therefore, the work proof of Bitcoin is the main work that we commonly call “mining”. In the process of “mining”, our core purpose is to find the corresponding decoding while there is not a fixed algorithm for any 64-bit hash value to find it and only depend on the randomly hash collisions of computers. The number per second of hash collision of a mining machine is the representative of its "power", and the unit is written as hash/s.
VB Network will continue to provide you with better products and better service, thank you for your support and understanding!
