These crypto currencies have been hot topic of discussion recently with the success of Ethereum. Today’s needull tries to explain what these are and the differences between Bitcoin and Ethereum.
The Ethereum blockchain is much faster than that of Bitcoin. The delay between two blocks in the bitcoin system is around 12 seconds. The propagation time of a block through the network, understandably, poses de facto new challenges. The Ethereum protocol provides solutions in both cases. Moreover, and this is the great innovation of this platform, one can arbitrarily store data on the blockchain—by which I mean smart-contracts—that are, in fact, programs written in a complete Turing language. There is thus no restriction on the complexity of programs that can be deposited on this particular blockchain.
