## Background
ipfs-blockchain-watcher is a collection of interfaces that are used to extract, process, and store in Postgres-IPFS
all chain data. The raw data indexed by ipfs-blockchain-watcher serves as the basis for more specific watchers and applications.
ipfs-blockchain-watcher is a collection of interfaces that are used to extract, process, store, and index
all blockchain data in Postgres-IPFS. The raw data indexed by ipfs-blockchain-watcher serves as the basis for more specific watchers and applications.
Currently the service supports complete processing of all Bitcoin and Ethereum data.
## Architecture
More details on the design of ipfs-blockchain-watcher can be found in [here](./documentation/architecture.md)
## Dependencies
Minimal build dependencies
* Go (1.13)
* Git
* GCC compiler
* This repository
Potential external dependencies
* Goose
* Postgres
* Statediffing go-ethereum
* Bitcoin node
## Install
1. [Goose](#goose)
1. [Postgres](#postgres)

These configuration parameters are broken down as follows:
`btcSubscription.wsPath` is used to define the SuperNode ws url OR ipc endpoint to subscribe to
`btcSubscription.wsPath` is used to define the ipfs-blockchain-watcher ws url OR ipc endpoint to subscribe to
`btcSubscription.historicalData` specifies whether or not ipfs-blockchain-watcher should look up historical data in its cache and
send that to the subscriber, if this is set to `false` then ipfs-blockchain-watcher only streams newly synced/incoming data

Currently, ipfs-blockchain-watcher persists all data to a single Postgres database. The migrations for this DB can be found [here](../db/migrations).
Chain-specific data is populated under a chain-specific schema (e.g. `eth` and `btc`) while shared data- such as the IPFS blocks table- is populated under the `public` schema.
Subsequent watchers which act on the raw chain data should build and populate their own schemas or separate databases entirely.
