The Fast Relay Network, also known as Matt Corallo's Relay Network, is a relatively straightforward relay network setup by Corallo, and has existed for some years. The Fast Relay Network consists of nine nodes, distributed strategically around the globe. Designed as a hub-and-spoke model, miners can connect to the relay node closest to them to send and receive blocks over this network. This is significantly faster than Bitcoin's peer-to-peer network.

Head First Mining is a trick proposed by former Bitcoin Core lead developer Gavin Andresen. With Head First Mining, miners don’t wait for the complete block to arrive before they start mining a subsequent block. Instead, they immediately mine on top of the block header as soon as they receive it, and also forward the header to other nodes. This obviously saves time.
