A possible solution for this The structure of the ethereum blockchain is very similar to bitcoin's, in that it is a shared record of the entire transaction history. Every node on the network stores a copy of this history. The big difference with ethereum is that its nodes store the most recent state of each smart contract, in addition to all of the ether transactions. 19 Feb 2017 Ethereum is a worldwide network of interconnected computers (nodes) that enforce, execute and validate programs in a decentralized manner without Equally, if people learn your public eth address, they can see what transactions you have made, otherwise, it is a random address making transactions.16 Nov 2017 You can also choose Ethereum Classic chain.

People Similarly, anyone can download the entire blockchain to become a full node, to analyze it, or simply for novelty. Improving privacy. Ethereum transactions are public, whereas Raiden transfers will be private between the payer, the payee, and the nodes forwarding the transfer. When channels are settled, only the sum of transactions will become visible to the entire world.

17 Jul 2017 For some reason, people keep asking us why Grid+ chose to operate on the public Ethereum blockchain as opposed to a private build.
