FVM x Bacalhau:
Bridging compute over state &
Compute over data
#BuildWithBacalhau

2.
Agenda aka the timestamps…
● Quick Project Demo & Tech Stack
● Bacal… what? The why’s and
how’s of Bacalhau
● The code!
○ Hardhat hyperspace deploy
○ NFT.Storage
○ Bacalhau Stable Diffusion
scripts
● Possibilities & Future for FVM x
Bacalhau

3.
FVM x Bacalhau
Better Together…

4.
Data, Data, Data!
Data, information and knowledge
are some of the most important
assets of our connected era and
have become critical to human
development & cooperation

5.
FVM brings on-chain user programmability to Filecoin
Bacalhau brings off-chain verifiable compute - both
unlocking the next layer of innovation and value
Storage
Computation over state
On-chain
Computation over data …
Off-chain
Storage is only the start…..

6.
Computation over State vs Computation over data…
Computation over state (on-chain
compute):
FVM enables computation over
state.
Allows monitoring and automation of
chain activities such as monitoring
and automating storage deals and
markets and enabling tokenisation of
data for dataDAOs + more.
Computation over data (off-chain,
verifiable compute):
Bacalhau enables complex
computation over data - any data
In the context of Filecoin & FVM,
Bacalhau will allow processing of
activities monitored on chain in a
verifiable and deterministic manner.
It enables a rich layer of data
processing for Filecoin & FVM

7.
Bacalhau & FVM
FVM - programmable data on small
amounts of state
Bacalhau - Computation over this
or any data including big data
with support for GPUs
Future: Bacalhau + FVM - calling
Bacalhau in your smart contracts!

8.
What’s stored on Filecoin?
If we look at some of the data stored on filecoin we’d find…
- Climate, space & geo-spatial data
- Academic research including quantum science data and genetics research
from several top tier universities
- Literature including an initiative for an Open Library with Harvard University
- HIstorically significant data such as data from holocaust victims and the
Ukraine
- Public record data such as election campaigns, or New York city public data
- Internet Archive’s cache of web information and pages
- Millions of unique collections of creative work in the form of NFT metadata
from art, videos, music, games and more

9.
Bacalhau?
Please allow me to introduce myself…

10.
Bacal.. - what ??
Bacalhau is a network of open
compute resources available to
serve any data processing
workload
- It’s simple to use (you don’t
need an AI degree!)
- Requires minimal operational
overhead or setup
- It’s decentralised-first (or
edge-first) principled
- Aims to provide efficient
distributed computation with
batched tasks

Bacalhau Platform Architecture
Bacalhau provides a platform for
public, transparent, and optionally
verifiable computation.
It enables users to run arbitrary
Docker containers and WebAssembly
(wasm) images as tasks against data
stored in the InterPlanetary File
System (IPFS)
It operates as a peer-to-peer network
of nodes where each node has both a
requestor and compute component

12.
Bacalhau System Components
● Requester node
(component)
● Compute node
(component)
● Transport layer
(interface)
● Executer (interface)
● Storage Provider
(interface)
● Verifier (interface)
● Publisher (interface)

Project Text-to-NFT
#BuildWithBacalhau

15.
Project Architecture
Tech Stack:
- NextJS, Typescript
- OZ Solidity ERC721 -
based contract
- Bacalhau Text-to-Image
Stable Diffusion Script
- NFT.Storage for
Metadata storage
- Deployment to
Hyperspace testnet with
Hardhat
- Front-end DApp
deployment on Fleek

16.
Demo!! 🎉

17.
Making & deploying an
NFT Contract to FVM
The contract, hardhat deployment & setup

18.
The Contract
Based off an Open Zeppelin ERC721
NFT contract.
The Mint function takes in an IPFS
CID = NFT Metadata,
Contract emits an event once minted
on the blockchain

19.
Hardhat Deploy
> npx hardhat run
./deployBacalhauFRC721.
ts --network
filecoinHyperspace

Open Source Text to Image
(Stable Diffusion) Script
Running Open Source Dall-E on Bacalhau!

Stable Diffusion Script aka the Text-to-Image script

22.
The Python Text-to-Image Script
This is the basic text to
image script. It uses a
keras/tensorflow
implementation of stable
diffusion (an ML model)
and then generates the
images from a given text
string and finally displays
the image generated.
The ML weights are pre-
calculated in the library

23.
Fetch… AI?!
Just a javascript fetch
function!
Under the hood this runs the
dockerised script on the
Bacalhau network.
The Bacalhau GPU nodes
will then run the job and
return an IPFS CID of the
results folder

Minting the
NFT on FVM
I’m using ethers to
connect to my
contract and
metamask wallet as
a transaction signer.

Bacalhau Computation over Data - use cases
Bacalhau lends itself well to performing repetitive, deterministic processing jobs
over data.
- ETL Processes
- Machine Learning & AI
- IOT data integration
- Batch Processing including for
- Financial and market data
- Video & Image processing

32.
Bacalhau x FVM….
- Help Onboarding and Offboarding of Filecoin data in the future
- Help build a reputation and Quality of Service layer for Filecoin by processing
data retrieved on-chain about deals and storage providers.
- Bacalhau could provide computation for market & payment data
- Bacalhau could help with processing data from DAO’s & DataDAOs
- Bacalhau could help empower more automation for creative endeavours like
video and images processing
- Bacalhau can enable game and metaverse data processing including for VR
& AR.
- Bacalhau, IOT & Simulations are possible
- AI & ML Applications
