Videos How to run Node Engram : Striatum - Lighthouse Client
This repository provides a docker-compose file to run a fully-functional, Testnet network for Engram Tokio with proof-of-stake enabled. This configuration uses Lighthouse as a consensus client and Striatum From Engram-Labs for execution.
The development net is fully functional and allows for the deployment of smart contracts and all the features that also come with the Lighthouse consensus client such as its rich set of APIs for retrieving data from the blockchain. This development net is a great way to understand the internals of Engram proof-of-stake and to mess around with the different settings that make the system possible.
Note, this is an incentivized testnet if you complete it correctly.
$ git clone --recursive https://github.com/engram-network/tokio-docker.git
$ cd tokio-docker
$ git checkout testnet
$ chmod +x ./scripts/*.sh
$ ./scripts/install-docker.sh
$ ./scripts/install-asdf.sh
$ mkdir -p execution consensus
docker-compose.yml : Stryatum - Lighthouse
docker-compose-besu.yml : Hyperledger Besu - Lighthouse
docker-compose-nethermind.yml : Nethermind - Lighthouse
docker-compose-reth.yml : RustETH - Lighthouse
Change a few lines of code inside docker-compose.yml (if you want to use the default, and the execution options and beacon will adjust as well.)
identity=avenbreaks << Replace with your discord username (e.g: avenbreaks. don't add your hastag discord user)
enr-address=13.210.210.210 << Replace with your public IPAddress
graffiti=avenbreaks << Replace with your unique name
Then, run:
$ docker compose up -d
You will see the following:
$ docker compose up -d
[+] Running 4/4
⠿ Network tokio_default_default Created
⠿ Container striatum_init Started
⠿ Container striatum_el Started
⠿ Container lighthouse_cl Started
Each time you restart, you can wipe the old data using ./clean.sh.
Next, you can inspect the logs of the different services launched.
$ docker logs striatum_el -f

FYI: if your node is stuck unable to pull sync and losing peers, you just stop docker then restart it. however if this solution does not solve you can replace the bootnode and noderecord here:
Consensus Specification.
When losing peers the normal logs will show up like this on consensus:

- Engram Validator Deposit Adress
0x11111c907e6ddfb954d5827c5b42cbca1ddc025eThis can be used to onboard new validators into the network by depositing 32 tGRAM into the contract
This guide will walk you through the process of depositing and running node on the Engram network.
Make sure you have eth2-val-tools and ethereal installed on your system.
wait until the binary installation is complete. and try to check
$ eth2-val-tools --help
$ ethereal versionOnce everything required is fulfilled, you need to create a mnemonic phrase to prepare the deposit data.
$ eth2-val-tools mnemonic
"female more wash genuine pilot slim exit mosquito glimpse blue science garlic creek upset acquire soup silent submit pitch spatial maple measure mutual picnic"and keep your mnemonic!
Not Your Key, Not Your Coin
Obtain the following parameters in validator-deposit-data.sh:
$ nano ./scripts/validator-deposit-data.shamount: The amount of tGRAM to deposit (e.g., 32000000000)
smin: source min value (e.g., 0)
smax: source max value (e.g., 1)
withdrawals-mnemonic: your mnemonic phrase from generate eth2-val-tools.
validators-mnemonic: your mnemonic phrase from generate eth2-val-tools.
from: address that was already funded from the faucet.
privatekey: your privatekey address that has funds from the faucet.
Run the following command to generate final the deposit data.
bash ./scripts/validator-deposit-data.shWait for the deposit to be verified by smartcontract and check in explorer.
