Setup The Blockchain Database

BigchainDB — The Blockchain Database

BigchainDB is a scalable and distributed database for Blockchain. Bigchain DB enables enterprises to deploy applications with Blockchain and Proof-of-Concept.

The combination of NoSQL database with Blockchain DB is one of its primary benefits. In BigchainDB, Data is represented as an “asset”. Any physical or digital object structured as JSON and key-values can be an "asset" or data in BigchainDB.

Let us have a look at the list of components that are required to set up Blockchain DB

1.MongoDB

MongoDB is the distributed database that will possess the Bigchaindb as a collection. You can run it on localhost or add an IP in the MongoDB config file to run it on a particular host IP.

2. Tendermint

Tendermint contains a genesis.json file. This file has the id and key pair for all the members on the network. To create a peer-to-peer connection, a minimum of 4 nodes are a must.

3. BigchainDB

The setup can be performed using docker-all-one install

1. docker pull bigchaindb/bigchaindb:all-in-one
2. docker run \
     --detach \
     --name bigchaindb \
     --publish 9984:9984 \
     --publish 9985:9985 \
     --publish 27017:27017 \
     --publish 26657:26657 \
     --volume $HOME/bigchaindb_docker/mongodb/data/db:/data/db \
     --volume $HOME/bigchaindb_docker/mongodb/data/configdb:/data/configdb \
     --volume $HOME/bigchaindb_docker/tendermint:/tendermint \
     bigchaindb/bigchaindb:all-in-one

After proper configuration and start of the setup, we need to examine the DB:

On CLI, run command “mongo”

• root@2de56a6c3953:/# mongo

          MongoDB shell version v3.6.17

• show dbs
  admin     0.000GB
  bigchain  0.001GB
  config    0.000GB
  local     0.000GB

• use bigchain

           switched to DB bigchain
 

• show collections
  abci_chains
  assets
  blocks
  elections
  metadata
  pre_commit
  transactions
  utxos
  validators

Post setup,  any transaction we perform at any time will be reflected in bigchain DB under assets, blocks, metadata, and transactions collections.
