Financial Data

Microtransactions


…But Blockchains Aren’t Perfect• Not sufficient on their own for many

applications• Because data is public• Need other technology and solutions

alongside blockchains• Private blockchains

• Zero Knowledge Proofs

• Ring signatures


Don’t re-invent decentralized security, there are new platforms Security and Privacy in the design, not as an after-thought

The Good News


Some Questions• Big problems with big databases• Privacy of customer information• Speed of financial settlements• Security of applications data• Online identity ownership Is the Web really secure?


What is Really Challenging Security?•Consensus engines on blockchains•Decentralization of computing architectures •Peer-to-peer clients

William Mougayar

Private data is stored, shared and analyzed without ever being fully revealed to any party

Secure multi-party computation Powered by the Bitcoin blockchain enigma.media.mit.edu


A Decentralized and distributed Social Platform.

A New P2P hypermedia protocol: Inter Planetary File System

ipfs.io


Traditional Web App• Client-side Javascript code run in

browser• Server-side code run by a host

dApp web3 • Client-side code in special browser• Blockchain ledger as a shared

resource• Smart logic runs on virtual network

of computers

A New Platform for Building Decentralized Applications.

Implications for the Future1. Secure data in applications2. Decentralize user data to protect it3. Learn Blockchains and

Decentralization technologies4. Write smart contracts on new / thin

cloud architectures (no servers)5. Rethink identity ownerships for your

customers
