slay3rd

Slay3r Daemon

This is the core application, and ABCI-enabled app that talks with tendermint to convert the powerful, pure-Rust state machine into a full-fledged blockchain.

Configuration

All values can be specified either in a slay3r.toml file (located in ~/.slay3r/config), via environmental variables (prefixed with SLAY_), or as command-line flags. The actions listed later take precedence over those listed earlier.

Any field not defined will use defaults from the code.

You can see this via:

SLAY_LOG="debug" cargo run -- --host 0.0.0.0

To see the full options:

cargo run -- -h

Running with CometBFT

Install Software

You can install version v0.38.0-alpha.2 of CometBFT by following the installation instructions

mkdir -p ~/golang
cd ~/golang
git clone https://github.com/cometbft/cometbft.git
cd cometbft
git checkout v0.38.0-alpha.2
make install

cometbft version
ls -l $(which cometbft)
# Around 26MB at v0.38.0-alpha.2!

You also need to install the slay3rd binary from this repo:

cargo install --path ./app/slay3rd

slay3rd -h
ls -l $(which slay3rd)
# Around 2.7MB at v0.2.0!

(Dev note: checking size and optimization...)

cd ./app/slay3rd
RUSTFLAGS='-C link-arg=-s' cargo build --release
ls -l ../../target/release/slay3rd
# Around 1.8MB at v0.2.0!

Setup Configuration

Set up basic tendermint

rm -rf ~/.slay3r
mkdir -p ~/.slay3r
cometbft init --home ~/.slay3r

Add the following to ~/.slay3r/config/genesis.json:

  "app_state": {
    "bank": [
      {
        "address": "layer1pkptre7fdkl6gfrzlesjjvhxhlc3r4gmt53rug",
        "balance": [
          {
            "amount": "4000000000",
            "denom": "uslay"
          }
        ]
      }
    ],
    "wasm": {
      "gov_account": "layer1pkptre7fdkl6gfrzlesjjvhxhlc3r4gmt53rug"
    }
  }

First execution

One terminal:

cometbft start --home ~/.slay3r

Second terminal:

slay3rd --log debug

Reset

Since we have a memory store for the app, once we stop it is out of sync with tendermint. We need to reset and restart. (We will be able to continue later with similar version once we have a disk store.)

cometbft unsafe-reset-all --home ~/.slay3r

Dev Mode

For debugging, let's run a quick build of slay3rd:

cd ./app/slay3rd
SLAY_LOG=debug,tendermint_abci::application=error cargo run

For cometbft, we also need to reset state every crash.

cometbft unsafe-reset-all --home ~/.slay3r
cometbft start --home ~/.slay3r

Then just keep restarting the cometbft and slay3rd process on crash

Update: you also need to run the gateway

cd ./gateway
go run main.go -grpc-server-endpoint localhost:9090

(Maybe with docker?)

docker run --network host ghcr.io/lay3rlabs/gateway:latest /app -grpc-server-endpoint localhost:9090
