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

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

Internet of value: a programmable economy

To develop shared global compute infrastructure,

we must first understand the status quo of infrastructure,

…and how to change it accordingly.

What about planetary scale?

Netflix uses 37% of Internet bandwidthUsing a modern distributed “big data” database

Writes / s vs. # nodes

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, optimizedvs

50-500 lines of slow custom code, unoptimized

How do “big data” databases scale? Answer: Distribute storage across many machines, i.e. sharding

A “consensus” algorithm keepsdistributed nodes in sync.

How to build a scalable blockchain database (BigchainDB)1. Start with an enterprise-grade distributed DB, e.g. MongoDB2. Engineer in blockchain characteristics

• Each DB node is a federation nodeDecentralized / Shared Control

• Append-only• Chain hashes

Immutable / Audit Trails

• “Own” = have private key• Asset lives on the database
