Aug 2, 2018 at 2:44 comment added Yoonsung Lee Ok, I understand it. Is the broadcast you mean different with the json RPC call to one node ? I first think that business server send the signed transaction using json RPC call to my public ethereum node. And then, the node will automatically broadcast the transaction on the blockchain network. Is it correct?
Aug 2, 2018 at 2:24 comment added Raghav Sood If your node holds the keys, you must unlock them before you can sign and send a transaction. If your business server holds the keys, it can sign the transaction locally and broadcast a complete, signed transaction.
Aug 2, 2018 at 2:13 comment added Yoonsung Lee Thanks @Raghav Sood. I don't understand 'where a presigned tx is broadcast, as you can avoid unlocking any keys on the server.' meaning. Can you explain more detail using physicall node construction ?
