Join Drew Falkman for an in-depth discussion in this video The Ethereum blockchain, part 2, part of Ethereum: Building Blockchain Decentralized Apps (DApps).
- [Instructor] Ethereum nodes only need to store the state,…instead of the entire blockchain history.…Blockchain history can be validated…through parsing of the encrypted tree.…Any wrong item is going to change the hash…for every branch above it.…Now one of the issues with this is…it could be a security risk,…because there could be fewer heavy nodes…with all the transactions,…and you could fake things to the light nodes.…For example, in the illustration above,…one of the hashes here a little ways up the tree…would be actually incorrect,…but it's been spoofed and changed,…and this can happen to alter one of the transactions…which would make it look…as if a different transaction occurred.…
When you're running heavy nodes,…it would find this far down in the chain…and discover that there was an issue.…One of the ways that Ethereum gets around this…is they require every minor to run a full node.…To learn more about Ethereum and their philosophies,…and to really get an understanding…of the value proposition of Ethereum,…
