Node installation
git clone https://github.com/kleomedes/prysm && cd prysm
git checkout v0.1.0-devnet
make install
prysmd version --long | grep -e version -e commit
# version: 0.1.0-devnet
# commit: f48a40b9541508c19b037e1a659c7ab048a1946d
We initialize the node to create the necessary configuration files
prysmd init UTSA_guide --chain-id prysm-devnet-1
Download Genesis
wget -O $HOME/.prysm/config/genesis.json "https://snapshots.polkachu.com/testnet-genesis/prysm/genesis.json"

# afe3fae047851409fa4e8bbb321a723fb4b2dc783bb5079c716bdf7df336e0c4
At this stage, we can download the address book
wget -O $HOME/.prysm/config/addrbook.json "https://share101.utsa.tech/prysm/addrbook.json"
Set up node configuration
