Blockchain – what is it good for?
Bozhidar Bozhanov, CEO @ LogSentinel
Terminology
Blockchain DLT Cryptocurrencies
Private /
permissioned
Key Strengths of blockchain
Provably
Immutable*
Distributed Trustless Hyped 
* Conditions apply
Main drawbacks of blockchain
Expensive
(if public)
Volatile Not scalable Not mature
Hard do code and
support
Real use cases?
E-voting
Food safety provenance
Land registry
Real estate deals
Insurance claims
Music royalties sharing
Waste management
Ads exchange
Inventory management
Healthcare data
Hotel reservations
Ride sharing
What do these have in common?
They can be done with
blockchain
They benefit nothing from
being distributed
They ride the
hype and FOMA
They will be very
hard to support
Why blockchain then?
Why “distributed” is not going to fly
Users don’t care
You have a centralized place
to get the “app” anyway
Private key
management sucks
It doesn’t solve many
real world problems
Cryptocurrencies?
“Bitcoin combines the Libertarian's two favorite things:
property and not understanding economics” --@ReinH
…
21st century tulip mania
Blockchain is not the new internet
Blockchain is not a
10x improvement over anything
…but it is very cool!
Technology components
Tamper-evident
data structures
Byzantine fault tolerance
Shared database
Shared code execution
Blockchain can solve problems
Prove
unmodifiability
Internal
lack of trust
Multi-stakeholder
databases
• Prove to 3rd parties that data has not been tampered with
• Logs, documents
• LogSentinel and Raiffeisenbank usecase
• Internal actors modifying data
• Anchor to public blockchain, avoid scalability and cost issues
• LogSentinel and SEGA usecase
• E.g. higher education diploma registers
• Practically a signed, shared database
• Car manufacturer + dealers usecase
Each component of blockchain
can solve real world problems.
Blockchain, blockchain, blockchain
Blockchain is the new cloud
…enabling digital transformation
through buzzwords
Remember all those projects?
They didn’t need blockchain, but blockchain was
the driver behind them.
Elements of a blockchain project
Digitize processes
Protect data integrity
Share a database
with partners
Use familiar technologies
Blockchain is not a revolution.
Blockchain can be the right tool for the job.
Just not for every job.
Thank you!
