What is Blockchain?
Tamper-proof distributed ledger.
Verifiable, immutable, traceable
Ledger = transactions &
states
No centralized authority = “trustless”

What does Blockchain solve?
With DLT: consistent, efficient, reliable, transparent,
immutable
Read-Write

Data A
Data B
Data C
Data D
Without DLT: inconsistent, expensive, inefficient,
questionable
Creates Trust in an environment of mistrust

Types of Applications
•send value from A to B •data: values •most mature •very good for cross border remittance
•example:
•manage simple values •supports simple business logic
•very good for simple use cases that need blockchain characteristics
•example:
•manage complex data •supports complex business logic
•very good for complex use cases that need blockchain characteristics
•example:
Payments (since 2008)
Smart Contracts (since 2013)
Immutable Database (since 2015)

What is the problem with Smart Contracts? Part 1
On-Ledger
Immutable “Transaction-Data”
Blockchain Implementation Example:
Advantage: + Immutable / unstoppable execution Disadvantage: - Immutable / unstoppable execution
contradicts implied covenant of good faith and fair dealing

“Introduction to Smart Contracts”, http://solidity.readthedocs.io/en/develop/introduction-to-smart-contracts.html
Smart Contract example
Smart Contract = Smart + Contract ???

iXBRL as an Extensible Smart Contract (Ricardian Contract)
Advantages: + Readable by non-programmers + Looks like a normal contract / report / form + Machine readable embedded “tagged” data + not proprietary!

Example iXBRL „Ricardian Contract“
Smart Contract = Smart + Contract
