O(1) Block Propagation

The problem

Bitcoin miners want their newly-found blocks to propagate across the network as quickly as possible, because every millisecond of delay increases the chances that another block, found at about the same time, wins the "block race."

The list of actions listed below was taken mostly from Book Of Zeus with minor modifications and did the job well for Ubuntu version, which was available at that moment (May 2016). This gist was created for internal use and was never meant to be discovered by the web, although Google managed to find and index this page, which was a great surprise for me.

### Keybase proof

I hereby claim:

  * I am diversified1 on github.
  * I am billy10 (https://keybase.io/billy10) on keybase.
  * I have a public key ASC1ML7wUvG6SbQtAxU8HSR060qsngDFK7MhtlvjIsokKwo

To claim this, I am signing this object:

physhster

*Important note to pay attention to* 
You'll most likely use eth0 on a USG and eth2 or eth3 on a USG-Pro, edit the files accordingly. Do not run the supplicant on virtual interfaces (e.g. eth0.0), as it will not work.

*Pre-requisites*
Get certs, run the mfg_dat_decode tool. You should end up with 3 certs: CA_*.pem, Client_*.pem and PrivateKey_PKCS1_*.pem, as well as a a wpa_supplicant.conf file

In the archive generated by the tool, edit wpa_supplicant.conf to add the full path /config/auth/ to all 3 files:

network={
        ca_cert="/config/auth/CA_xxxxxx.pem"
