CosmWasm Integration

Deploy Llama models to CosmWasm blockchains, because regular cloud deployments were just too reliable.

Introduction to CosmWasm

Or: "How I Learned to Stop Worrying and Love the Blockchain"

CosmWasm is a smart contracting platform built for the Cosmos ecosystem. We've decided to make your AI deployment experience more exciting by adding the complexity of blockchain technology to it. Because why use simple, proven cloud infrastructure when you can put your model on an immutable ledger?

Important Note

This integration is perfect for those who enjoy explaining to their boss why their model deployment costs 10x more and runs 100x slower than a traditional deployment. But hey, it's on a blockchain!

Prerequisites

Things you'll need before embarking on this journey of questionable decisions

1
A Cosmos wallet
Preferably one with funds you're willing to sacrifice to the blockchain gods.
2
Rust installed
Because JavaScript wasn't frustrating enough, let's add memory management to the mix.
3
Docker
For when you want your computer's fan to sound like a jet engine.
4
Infinite patience
You'll need it when your transaction fails for the fifth time due to "gas estimation errors."

Deployment Steps

Follow these steps carefully, or don't. The blockchain is unpredictable either way.

$ cargo wasm

This command compiles your Rust code into WebAssembly. It will probably fail the first time due to some obscure dependency issue. This is normal and part of the authentic blockchain experience.

$ docker run --rm -v "$(pwd)":/code \ --mount type=volume,source="$(basename "$(pwd)")_cache",target=/code/target \ --mount type=volume,source=registry_cache,target=/usr/local/cargo/registry \ cosmwasm/rust-optimizer:0.12.11

This command optimizes your WASM binary. It's also a great way to heat your room in winter.

const client = await SigningCosmWasmClient.connectWithSigner(
  rpcEndpoint,
  wallet,
  { gasPrice: GasPrice.fromString("0.025ujuno") }
);

const wasm = fs.readFileSync("artifacts/llama_model.wasm");
const uploadResult = await client.upload(wallet.address, wasm, "auto");
console.log("Contract Code ID:", uploadResult.codeId);

This code uploads your contract to the blockchain. The "auto" gas setting means "please take whatever amount of my money you'd like."

Common Issues

A non-exhaustive list of the many ways this can go wrong

Gas Estimation Failed

This error means the blockchain has no idea how much to charge you. Solution: Increase your gas limit until either the transaction succeeds or you run out of tokens, whichever comes first.

Contract Size Too Large

Turns out, putting a multi-gigabyte AI model on a blockchain designed for kilobyte-sized contracts isn't ideal. Who knew?

Out of Memory

The blockchain validator ran out of memory trying to process your model. Consider using a smaller model, or perhaps reconsidering your life choices.
