Everything about working with the Ethereum blockchain is found
These are notes for the sixth video.
This video shows how to create signed transactions in a secure local environment and then send them to the public Ethereum blockchain without the need to run an Ethereum node or do any mining.
The biggest advantage to creating signed transactions is security. The idea is to create a signed transaction offline with an air-gapped computer. An air-gapped computer is a computer which is not connected to the Internet. This greatly reduces the chances that hackers can spook around your computer and find your private key.
Two methods are shown. One uses a service called INFURA and the other uses a service called BlockCypher.
We will be working with INFURA first.
