you get a list of nodes by DNS resolving seed.bitcoin.sipa.be
then you connect at port 8333 and speak the "BTC" protocol or whatever and either listen for a bunch of data, or push your own data (like a transaction)
where is the validation part that you are referring to?
- zamadatix 5y agoBlockchain cryptographically stores that transaction in the state of the blockchain (hence it being a chain) for the rest of time. With DHT you can exchange info between nodes but nobody else is validating the data and when the nodes go offline the data disappears.
- MuffinFlavored 5y agoHow does that work with exchanges like Coinbase? In order to validate their transactions, you have to walk back a ton of transactions?
