Officially stated requirements: 2/4/100 ubuntu 22.04

✅UOMI Finney Incentivized Testnet Launched

50,000,000 $UOMI tokens allocated to reward node operators starting with this testnet!

Validators are the core of the UOMI ecosystem, powering block production, AI computation, and cross-chain interaction. By running a validator node, you actively contribute to the growth of the network, and $UOMI tokens are rewards for your participation

Choose the node type that suits your setup:

RPC nodes: light, full, or archive, optimized for data access and interaction (these node types are subject to question regarding rewards) Validator nodes: require 48GB of GPU RAM and a full node setup to validate transactions and secure the network

IMPORTANT:

The validator requires a server with a video card (cards) that has 48 GB of video memory!!!
This guide is suitable for ubuntu 24.04

Validator setup

Download genesis

wget -O /usr/local/bin/genesis.json "https://github.com/Uomi-network/uomi-node/releases/download/v0.1.7/genesis.json"
chmod +x /usr/local/bin/genesis.json

sha256sum /usr/local/bin/genesis.json
#ac62c78e9465fdb25fce6e98138fd497089042785ac4bac70d75d379efddfb49

Download the binary file

wget -O /usr/local/bin/uomi "https://github.com/Uomi-network/uomi-node/releases/download/v0.2.3/uomi_ubuntu_24"
chmod +x /usr/local/bin/uomi
uomi --version
#uomi 0.2.3-08ac2217fb9

Create a wallet and save the output

uomi key generate --scheme Sr25519

# output example

Be sure to save the wallet output. We will need the data later

Generate the Ed25519 key for GRANDPA using your seed phrase obtained above

uomi key inspect --scheme Ed25519 "<YOU_SEED>"

Be sure to save the wallet output. We will need the data later

IMPORTANT - if the node cannot connect to peers, then add a backup peer to the service file

--reserved-nodes "/ip4/5.9.87.231/tcp/30333/p2p/12D3KooWCAChuDHHpNER855r6NpAGDeLrSZ4U3sP6FocSWWJZDf5"

Adding Keys STEP 1

Once your node is up and running, paste your keys

NOTE - replace SECRET_PHRASE and PUBLIC KEY (hex) with your data obtained with the first command "key generate --scheme Sr25519"

for key_type in babe imon uomi ipfs; do
    curl -H "Content-Type: application/json" \
        -d '{"id":1, "jsonrpc":"2.0", "method":"author_insertKey", "params":["'$key_type'", "SECRET_PHRASE", "PUBLIC_KEY"]}' \
        http://localhost:9944
done

Adding Keys STEP 2

NOTE - replace SECRET_PHRASE and PUBLIC KEY (hex) with your data obtained using the second command "key inspect --scheme Ed25519"

curl -H "Content-Type: application/json" \
    -d '{"id":1, "jsonrpc":"2.0", "method":"author_insertKey", "params":["gran", "SECRET_PHRASE", "PUBLIC_KEY"]}' \
    http://localhost:9944

Finally after the node is fully synced run the following command to generate session keys when creating a validator in polkadot js

curl -H "Content-Type: application/json" -d '{"id":1, "jsonrpc":"2.0", "method": "author_rotateKeys", "params":[]}' http://localhost:9944
