Sharding Scalability Technology
Zentacore will employ sharding to drastically improve on scalability and transaction speeds of the Ethereum blockchain. The easiest way to understand how sharding functions is to draw parallels with horizontal database partitioning. Imagine having a large database containing millions of records and trying to search for ones by containing only a certain attribute. From a technical perspective, this is a task that takes a significant amount of time to execute. However, if we were to partition the database into tables according to its attributes, it would decrease the search time, as only a single table would be queried in that case. The sharding solution is interconnected with the entire ZentaChain ecosystem and enables partitioning and storing of the entire blockchain within nodes (shards) which are then responsible for validating solely the transactions contained within them as opposed to each node having to process every single transaction on the blockchain.
The demand for scalability on the Ethereum becomes increasingly urgent. The Cryptokitties incident demonstrated how quickly the Ethereum network can prevent it. ZentaChain will use Sharding to establish a high TPS, future proof infrastructure. Understanding why ZentaChain uses Sharding: One of the major problems of a blockchain is that an increase in the number of nodes reduces its scalability. This may be counterintuitive because more nodes do not result in more power or speed, the opposite is true: One of the reasons why a blockchain has its level of security is because every single node must process every single transaction. This is like having your report checked by every single accountant in the company. While this may ensure that your report is faultless, it will also take a long time before you get it back and finally approved. Ethereum faces a similar problem. The nodes are your accountants and each transaction is your report.
Proof-of-Stake (PoS) protocols were developed as energy-saving alternatives to PoW. Instead of computational power resources, leaders are selected based on their stakes. Particularly in the PoS consensus mechanism, the stake of a node is the number of digital tokens Zenta in cryptocurrencies, that it holds or deposits in Zentawallet. Instead of consuming a lot of energy for the searching process as in the PoW, a leader will be selected based on its stakes to perform mining process and add a new Zenta blocks to the chain.
