Key Considerations

• Scalability • Security and Privacy • Throughput • Governance • Consensus • Smart Contracts Blockchain Platforms Prominent Platforms

• Public/Permissionless • • • Private/Permissioned • Fabric • Corda • Multichain • Quorum / Enterprise Ethereum • Ripple Bitcoin / Ethereum – Structure
