OrbitDB Custom Store
npm install orbitdb-tokenstoreDatabase for storing indexed array based on OrbitDB docStore
The purpose of this extension is to override default _put_ function in order to provide a mandatory __tokens_ field. Every time a _put_ is called the list passed will be merged into the older one.
> yarn add orbitdb-tokenstore
