There are 2 options to get the binary:
wget http:https://electra01.alkia.net:3000/electrad.7z
p7zip -d electrad.7z
Github limit http upload to 25M max and we are a bit over so we needed to split in 2 files (command: split -b 20M electra_linux_amd64.tar.gz ):
-
electra_linux_amd64.tar.gz.part_aa
-
electra_linux_amd64.tar.gz.part_ab
You join the files using the cat command. Employing cat is the most efficient and reliable method of performing a joining operation.
cat electra_linux_amd64.tar.gz.part_* > electra_linux_amd64.tar.gz#####Security note: Please check that the checksum provided match the reconstructed electra_linux_amd64.tar.gz
tar -xvf electra_linux_amd64.tar.gz
This gives you the binary electrad

NOTES:
- Use only alphanumeric characters, hyphens, and underscores for your node name.
- If you are using secondary storage: You need to add a --home flag where you direct the command to the path of your secondary storage. By default, und init uses --home /home/$USER/.und_mainchain if you do not specify otherwise.

At first, you will see an error message, e.g.:
E[2020-03-19|09:42:06.072] Stopping peer for error module=p2p peer="Peer{MConn{1.2.3.4:26656} dcff5de69dcc170b28b6628a1336d420f7eb60c0 out}" err=EOF This is normal. Wait. Eventually, you will see your node downloading blocks. Once you are happy seeing the blocks roll in, hit CTRL+C to stop the node.

Running a production-quality validator node with a robust architecture and security features requires an extensive setup.
Electra chain is powered by the Tendermint consensus. Validators run full nodes, participate in consensus by broadcasting votes, commit new blocks to the blockchain, and participate in governance of the blockchain.
Validators earn the following fees:
- Gas: Fees added on to each transaction to avoid spamming and pay for computing power. Validators set minimum gas prices and reject transactions that have implied gas prices below this threshold.
- Validators get coins as rewards proportional to their shares
If validators double sign or frequently offline, their credibility will be slashed. Penalties can vary depending on the severity of the violation.
