This document discusses a scalable blockchain database called BigchainDB. It begins by discussing issues with traditional centralized databases and blockchains, then introduces BigchainDB as a hybrid solution that uses a federated consensus model between nodes running an enterprise-grade distributed database like MongoDB to provide blockchain attributes of decentralization, immutability and native digital assets at planetary scale. It provides examples of potential applications for BigchainDB across various sectors like IP, identity, finance, energy, supply chain and government. It also discusses the IPDB Foundation caretaker model for operating and maintaining BigchainDB nodes.
Meetup 19/12/2016 - Blockchain-as-a-service voor Antwerpen?
- 1. A scalable blockchain database Dimitri De Jonghe [email protected]
- 2. Your assets, your claims
- 4. Trust by Institutions & Intermediaries
- 5. $ ping www.google.com < PING www.google.com (172.217.17.36) Digital Trust by Institutions & Intermediaries
- 8. Blockchain Disruption Shared single source of truth and conduct Inter- mediary Trusted third parties peer to peer decentralized centralized
- 9. Blockchain: a special “spreadsheet in the sky” What’s special? ● Not a single instance owns it ● Members/clients can add to it ● If they follow the rules ● Rules are an integral part ● No one can change the history (immutable) ● Writing to a blockchain is like etching into stone ● Which allows us to issue assets and transfer them
- 10. Shades of trust, reputation, blockchain... Public: Open networks Writers: Everyone can participate Trust: World consensus Applications: ● Decentralized apps ● Cryptocurrencies, programmable money ● Smart contracts Private: Ecosystems, federations Writers: Participants known/reputation Trust: Federated consensus (eg voting) Applications: ● Disintermediation: Clearing & settlement ● Transparency: Supply chain, AML, audit trails, provenance ● Ownership: exchange, partial, trustless
- 11. Internet of value: a programmable economy
- 12. To develop shared global compute infrastructure, we must first understand the status quo of infrastructure, …and how to change it accordingly.
- 13. Status quo compute infrastructure Modern apps use processing, file system, database FILE SYSTEM e.g. S3, HDFS APPLICATION PROCESSING e.g. EC2, Azure DATABASE e.g. MySQL, MongoDB PLATFORM e.g. AWS, Google App Engine, Heroku CONNECTNETWORKS e.g.TCP/IP
- 14. Towards a decentralized compute infrastructure FILE SYSTEM e.g. S3, HDFS APPLICATION PROCESSING e.g. EC2, Azure DATABASE e.g. MySQL, MongoDB Bitcoin Blockchain? PLATFORM e.g. AWS, Google App Engine, Heroku CONNECTNETWORKS e.g.TCP/IP

- 16. Towards a decentralized compute infrastructure FILE SYSTEM e.g. S3, HDFS IPFS, SWARM APPLICATION PROCESSING e.g. EC2, Azure, Ethereum, Hyperledger, Tendermint, Lisk, Corda DATABASE e.g. MySQL, MongoDB PLATFORM e.g. AWS, Google App Engine, Heroku, Eris/Monax, BlockApps CONNECTNETWORKS e.g.TCP/IP,InterledgerILP e-Cash/e-Gold Bitcoin, zCash, Ripple, Blockstream, Multichain

- 19. 70 GB 3 tx/s What about planetary scale?
- 20. Netflix uses 37% of Internet bandwidth Using a modern distributed “big data” database http://techblog.netflix.com/2011/11/benchmarking-cassandra-scalability-on.html Writes / s vs. # nodes
- 21. What’s the difference between a database and a csv file? Querying. From M’s of records, find the relevant ones. 1 Line of standard code, optimized vs 50-500 lines of slow custom code, unoptimized
- 22. How do “big data” databases scale? Answer: Distribute storage across many machines, i.e. sharding A “consensus” algorithm keeps distributed nodes in sync.
- 23. Native assets How to build a scalable blockchain database (BigchainDB) 1. Start with an enterprise-grade distributed DB, e.g. MongoDB 2. Engineer in blockchain characteristics • Each DB node is a federation node Decentralized / Shared Control • Append-only • Chain hashes Immutable / Audit Trails • “Own” = have private key • Asset lives on the database
- 24. Federated Consensus Architecture Blockchain Consensus Database Consensus IMPLEMENT A 2 PHASE CONSENSUS FEDERATION Single Database or MongoDB RethinkDB Database Options
- 26. BigchainDB: Big Data meets Blockchain - a blockchain database Immutability Decentralized Control Native Assets Scalable Queryability Operationalized Traditional Databases Traditional blockchains BigchainDB
