## Overview
This is a 'boilerplate' repository. It's intended to be forked to start new projects. However, it can also be run as a stand-alone Circuit Relay, for supporting the PSF network.
This is a 'boilerplate' repository. It's intended to be forked to start new projects. Some code projects that are forks of this repository and regularly pull in changes:
- [pay-to-write database (P2WDB)](https://p2wdb.com/)
- [ipfs-bch-wallet-consumer](https://github.com/Permissionless-Software-Foundation/ipfs-bch-wallet-consumer)
- [ipfs-bch-wallet-service](https://github.com/Permissionless-Software-Foundation/ipfs-bch-wallet-service)
In addition to being forked as a boilerpalte, it can also be run as a stand-alone application to create a [Circuit Relay](https://cashstack.info/docs/local-back-end/circuit-relay), which can support the [PSF](https://psfoundation.info) IPFS network. It can also be used for experimenting with [helia-coord](https://github.com/Permissionless-Software-Foundation/helia-coord) and the [psf-bch-wallet](https://github.com/Permissionless-Software-Foundation/psf-bch-wallet) command-line wallet.
## Boilerplate

- Access and rate-limit control using [JWT tokens](https://jwt.io/)
This boilerplate extends that code to provide the basic features required to be a 'service provider' on the [IPFS](https://ipfs.io) network. This is a core concept in the [web3 Cash Stack](https://cashstack.info). These basic features include:
- [ipfs-coord](https://www.npmjs.com/package/ipfs-coord) for coordinating service providers and consumers across the IPFS network.
- [helia-coord](https://github.com/Permissionless-Software-Foundation/helia-coord) for coordinating service providers and consumers across the IPFS network.
- JSON RPC for creating an API between providers and consumers.
If you are interested in creating your own service provider on the IPFS network, fork this repository and start building.
