Rather than trying to scale up blockchain technology, BigchainDB starts with a big data distributed database and then adds blockchain characteristics - decentralized control, immutability and the transfer of digital assets.
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
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

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
