BigchainDB is a "blockchain database"..
..With high throughput, low latency, powerful query functionality, decentralized control, immutable data storage and built-in asset support, BigchainDB is like a database with blockchain characteristics.(bigchaindb.com)
It's a good choice for who wants to work with immutable databases.
Here's a tutorial to deploy a local infrastructure docker based.
(I'm using Debian Buster, but the project recommends latests Ubuntu and CentOS)
Requirements
- Docker(19.03+)
- Docker-Compose (2.0+)
- python3.6+
- pip3+
- bigchaindb_driver(for the tests, install via pip3)
Clone Repo
$ git clone https://github.com/bigchaindb/bigchaindb.git
Install
Bigchaindb Dependences
$ sudo bash bigchaindb/pkg/scripts/bootstrap.sh --operation install
Deploy Docker Compose
$ docker-compose -f bigchaindb/docker-compose.yaml up -d
Check Containers
$ sudo docker ps

Testing db
Create testdb.py to test your installation:
from bigchaindb_driver import BigchainDB
from bigchaindb_driver.crypto import generate_keypair
from time import sleep
from sys import exit
alice, bob = generate_keypair(), generate_keypair()
bdb_root_url = 'http://localhost:9984' # Use YOUR BigchainDB Root URL here
bdb = BigchainDB(bdb_root_url)
bicycle_asset = {
'data': {
'bicycle': {
'serial_number': 'abcd1234',
'manufacturer': 'bkfab'
},
},
}
bicycle_asset_metadata = {
'planet': 'earth'
}
prepared_creation_tx = bdb.transactions.prepare(
operation='CREATE',
signers=alice.public_key,
asset=bicycle_asset,
metadata=bicycle_asset_metadata
)
fulfilled_creation_tx = bdb.transactions.fulfill(
prepared_creation_tx,
private_keys=alice.private_key
)
sent_creation_tx = bdb.transactions.send_commit(fulfilled_creation_tx)
txid = fulfilled_creation_tx['id']
asset_id = txid
transfer_asset = {
'id': asset_id
}
output_index = 0
output = fulfilled_creation_tx['outputs'][output_index]
transfer_input = {
'fulfillment': output['condition']['details'],
'fulfills': {
'output_index': output_index,
'transaction_id': fulfilled_creation_tx['id']
},
'owners_before': output['public_keys']
}
prepared_transfer_tx = bdb.transactions.prepare(
operation='TRANSFER',
asset=transfer_asset,
inputs=transfer_input,
recipients=bob.public_key,
)
fulfilled_transfer_tx = bdb.transactions.fulfill(
prepared_transfer_tx,
private_keys=alice.private_key,
)
sent_transfer_tx = bdb.transactions.send_commit(fulfilled_transfer_tx)
print("Is Bob the owner?",
sent_transfer_tx['outputs'][0]['public_keys'][0] == bob.public_key)
print("Was Alice the previous owner?",
fulfilled_transfer_tx['inputs'][0]['owners_before'][0] == alice.public_key)
Execute Test Script
$ python3 testdb.py
[out]Is Bob the owner? True
[out]Was Alice the previous owner? True

Run "docker-compose -f bigchaindb/docker-compose.yaml up -d" with sudo and replace .yaml with .yml
I had to do this while I was installing it on Ubuntu 18.04
Hi Carlos,Have you tried docker swarm with Bigchaindb?
