This week I have a talk on a meetup about blockchain beyond the hype – its actual implementation issues and proper use-cases.
The slides can be found here:
The main takeaways are:
- Think of blockchain in specifics, not in high-level “magic”
- Tamper-evident data structures are cool, you should be familiar with them – merkle trees, hash chains, etc. They are useful for other things as well, e.g. certificate transparency
- Blockchain and its cryptography is perfect for protecting data integrity, which is part of the CIA triad of information security
- Blockchain (a private one) can be a good enterprise integration solution for multi-organization setups where trust is required
- Many proposed use-cases can be solved with centralized solutions + trusted timestamps instead
- Usability is a major issue when it comes to wider adoption
As with anything in technology – use the right tool for the job, as no solution solves every problem.
