ETH (ETHEREUM): Challenges

The Ethereum Blockchain presently supports fifteen transactions per second which is way too less compared to Visa processing 45,000. Ethereum and bitcoin adapt to certain technological tricks to ensure credibility of information it generates and maintains. ‘Sharding’ breaks a database into smaller pieces.  Nodes store the entire ethereum transactions and reveals account balances and contracts. With every new block, the number of transactions keep increasing and raise in size of each block, will increase the need to store larger and larger data in the node. Although the network can handle only less transactions per second compared to Visa-scale transactions, the creators and  developers have high hopes on good functioning in future.
