Advanced Features with Catapult: Building the Future of Blockchain Applications
- 1. Advanced Features with Catapult: Building the Future of Blockchain Applications Cebu, Philippines May 10th, 2018 Presented by Jeff McDonald LuxTag.io CTO www.nem.io
- 2. Clients Server Database (It is a master copy!) Centralized (efficient but not secure) Decentralized (Not efficient but very secure) TRUST, SECURITY& MARKETS
- 3. WHAT DOES IT SOLVE? Blockchain is a decentralized database solution that creates a new model of trust, security, and serves new markets.
- 4. Blockchain Database Bitcoin Bitcoin is a single purpose database. It is designed to send BTC.
- 5. Blockchain Database Ethereum Ethereum is a blockchain designed to send ETC Ethereum also has a VM. • ETC is 1. money 2. gas • Gas powers a virtual machine. • Contracts exist in the VM.
- 6. Blockchain Database NEM really makes the blockchain as a true database solution. IoT NEM can be used for all these other use cases by adding support for all these features directly into the core via plugins or as 2nd layer standards. ID
- 7. Three Layers of Business Logic CORE PLUGINS & FEATURES Multisig, Namespaces, Mosaics, Messaging PROTOCOLS & STANDARDS Voting, Apostille OFF-CHAIN CONTRACTS ICO maker, XEMsign
- 8. Apostille Standard Notarization is updatable, augmentable, transferable, can be certified by third parties, and can be conjointly owned. And now IOT integration TRANSFER NOTARIZATIONS CONJOINTLY OWN 3RD PARTY CERTIFICATION
- 9. VOTING
- 10. Aggregate Transactions 7-11PaysFees Bank: USD Alice 7/11 $2 A B 0.05 XEM
- 11. Aggregate Transactions App/Project Creator PaysFees Bank: USD Alice Chuck Bob Patrick $0.02 B 0.05 XEM C $5 A Patcoin + Patcoin App = PATpay»

- 13. End User Example 1-of-2 $$$ Account Mother Restore AccountUser’s Phone Brother 2-of-2 Alice Bob Best Friend Signer Multisig Account Lost Private Key Contract • User has a back up with friends MULTI-LAYERED MULTISIG TRANSACTIONS 2-of-2 2-of-3 Best Friends Unique 1-of-1 multisig
- 14. IoT 99% of txs 2-of-3 User Account Device $$$ 2-of-2 IOT Device Manufacturer AI Manufacturer Account Device Signer NotifyNotify 1-of-2 Signer Multisig Account • Public Network Settings • Max of 3 levels • One account up to 10 cosigners • One account up to 5 contracts IOT • Now devices can safely own funds MULTI-LAYERED MULTISIG TRANSACTIONS
- 15. NEM’sAPIs Building on a smart blockchain has never been easier Developers love NEM’s JSONrestful APIs and SDKs

Editor's Notes
- Centralized is a read and write database. Blockchain is a write once, read many database. Blockchain is a cryptographically safe, secure, decentralized and immutable database. The cryptography shows direct A -> B history, and the decentralization shows that it wasn’t ever tampered with. Decentralization also helps to make sure that apps can’t be censored and that it is available in all markets all the time. Centralized databases predate the internet and therefore don’t have security built in to compensate for a post-internet world where hackers can remotely attack.
