[fungistore] research 'distributed' data stores (mainly for key/value)

[muhamadazmy]

We need this for the BLOB storage backend

• ZDB (standalone) -> this has to be supported anyway
• Tendermint over ZDB -> Can we change the transaction log backend of tendermint to use zdb instead? The final state can then be stored in another data store that is more space efficient (say rocksdb)
• etcd (how much data can it hold, size of objects, etc..?)
• seaweedfs: this is not a key-value store, but a store for unstructured data (files, objects) more like S3.
• minIO ?
• R2 (cloud-flare)
• redis cluster
• IPFS

Criteria:

• Consensus/Decentralized
• Dedub
• Object size
• Number of objects
• Total size limit
• License
• Build process/ deployment/ etc..
