In this slide, I talked about why Blockchain as a technology may not be a feasible solution to your problems. This is a lightning talk that I presented in NDC Sydney 2018.

1. Why Blockchain
doesn’t make sense

2. –Michael John Peña
“Finding a solid use case for Blockchain is hard
because it involves Partnerships, Technical
Readiness and Cultural Uplift. But when you found
one, it really makes a lot of sense.”

3. You don’t have partners
• You are centralising the governance of the nodes
• A business unit owns and manages the infrastructure
• There is no trust issue that you want to solve

4. It’s hard to scale
• Public Blockchain (like Ethereum on MainNet and Bitcoin)
is expensive and not fast enough.
• Infrastructure cost of semi-private Blockchain is also
expensive
• Versioning of “Smart Contracts” is painful

5. Further Challenges
• It doesn’t solve the “Who am I” problem in a Decentralised
Voting System. Maybe Biometrics can?
• Regulation is getting harder (for Public Apps)
• It gets too complex that has little to no value for end users

6. Thank you.
