Bitcoin Blockchain and its shortcomings

THE ESSENCE OF THE BITCOIN BLOCKCHAIN

Single asset, distributed, immutable ledger for transactions

General purpose, permanent, data store

SHORTCOMINGS OF THE BITCOIN BLOCKCHAIN

• Limited capacity: 3-7 transactions/sec ~ 1 block per 10 minutes

• Transaction costs: around 20 cents per transaction

• Irrelevant data: well over 50GB of data at this time

• Open nature: anyone can connect, read and write

• Single asset: workarounds with metadata needed to do more

The Multichain solution

THE MULTICHAIN FORK SOLUTION

• Private Blockchain: control who connects, reads and writes

• Customise mining: configure diversity, blocksize and frequency

• No mining/transaction fees: due to the private nature

• Application specific chains: no irrelevant data

• Multiple asset support: from currency to financial instruments to ...

• Atomic exchanges: prevent double spend and one sided transactions

• Docker Compose: easy and shareable services orchestration

• A preconfigured experimentation environment

• Starts 1 master and 3 slave nodes

• Installs and configures Multichain Explorer
