Filecoin Storage Deal Making Service

Delta is a deal-making service that enables users to make deals with Storage Providers. It is an application that allows users to upload files to the Filecoin network and get them stored by Storage Providers.

For more information, check out the docs

Build and Run Delta

Prepare to build

Copy the .env.example file to .env and update the values as needed.

# Node info
NODE_NAME=stg-deal-maker
NODE_DESCRIPTION=Experimental Deal Maker
NODE_TYPE=delta-main

# Database configuration
MODE=standalone
DB_DSN=delta.db
#REPO=/mnt/.whypfs # shared mounted repo

# Frequencies
MAX_CLEANUP_WORKERS=1500

Install and run Delta using docker

Running this the first time will generate a wallet. Make sure to get FIL/DataCap from the faucet and fund the wallet

Make sure you have docker installed on your machine.

Run the current delta clone using docker-compose

If you already have a wallet with datacap, you can pass it to the command below. This copies over the wallet directory to the containerized app and sets it as the default wallet.

make docker-compose-run WALLET_DIR=<walletdir>

Check localhost

You can check the localhost to see if the delta app is running

curl --location --request GET 'http://localhost:1414/open/node/info'

Next

Now that you can access a live Delta node, you are now ready to make a deal. You can now go to the following guides:

• Make an e2e deal
• Make an import deal

Run a specific docker image tag from the docker hub artifactory

We have a few pre-built images on the docker hub artifactory. You can run the following command to run a specific image tag

cd docker
./run.sh <TAG> 

Note: no tag means it'll just get the latest image.

Install, build from source and run Delta

Install the following pre-req

• go 1.19
• jq
• hwloc
• opencl
• rustup
• postgresql

Alternatively, if using Ubuntu, you can run the following commands to install the pre-reqs

apt-get update && \
apt-get install -y wget jq hwloc ocl-icd-opencl-dev git libhwloc-dev pkg-config make && \
apt-get install -y cargo

Using make

make all
./delta daemon --repo=.whypfs --wallet-dir=<walletdir>

Using go build

go build -tags netgo -ldflags '-s -w' -o delta
./delta daemon --repo=.whypfs --wallet-dir=<walletdir>

Run Delta

./delta daemon --mode=standalone

Test the API server

Try the following endpoints to test the API server

curl --location --request GET 'http://localhost:1414/open/node/info'
curl --location --request GET 'http://localhost:1414/open/node/peers'
curl --location --request GET 'http://localhost:1414/open/node/host'

If it return the following, then the API server is working

{"name":"stg-deal-maker","description":"Experimental Deal Maker","type":"delta-main"}
