My talk on Bitcoin and our new site: http://min.io at #hackstb. Min.io is a very easy way to sell your digital goods for Bitcoin.

1. Min.io & Bitcoin
#hackstb

2. What is Bitcoin?
• Decentralized medium of exchange, that allows
• Instant, anonymous* worldwide value transfer
• For little fees.
• Other features:
• Finite supply
• Infinitely* divisible
• Created through “mining”.

3. Decentralized
• Network of computers verify transactions
together.
• Solves Byzantine-Generals problem.
• Reaches consensus through proof-of-work.

4. Instant value transfer
• Your money is just bits and bytes anyway.
• Why can I send a message instantly across the
world, but not money?
• *Anonymous:
• Whose address is this?
18HY7u8RTfXU9AsQHiK8yaaJJ56k3S1U1n

5. Zero (or little) fees
• Fees prioritise your transaction and
• Supports the miners (computers verifying
transactions).

6. Limited Supply
• 21 Million BTC. (more finite than Gold).
• Rate halved every 4 years. Was 50/10min.
Now 25/10min.

7. Infinitely* Divisible
• 21 Million BTC up to 8 decimals.
• 0.00000001 = 1 Satoshi.
• Can divide as much as the network wishes.

8. “Mining” (compute hashes)
• Topic on its own. In short:
• Computers help verify transactions on the
‘shared ledger’.
• By computing the correct hash to a block, they
show they have provided proof-of-work and
block gets appended.
• Reward: 25 BTC/block.

9. Why is it amazing?
• Central authorities can’t devalue your money (see
hyperinflation).
• Mathematically enforced scarcity.
• More divisible than any money (see deflationary
critiques).
• Very small fees to transfer value across the globe.
• Open source.
• Worldwide market for payments.

10. I want to be a part of this!
• Most exciting experiment in the world since
the internet!
• Mining? Nope.
• Trading? We are not traders.
• We can code! Let’s make something!
• Contributes to economy.

11. I want to be a part of this!
• PayPal doesn’t cover the world, and takes long
to set up.
• It’s easy to pay if you have a credit card.
Difficult to accept payments.
• We are creators… so let’s make it easy to
accept Bitcoin for digital goods.

12. Min.io
• Easily sell your digital goods for Bitcoin.
Enabling creators.
• Upload item, set price, share it!
• Demo time!

13. Min.io: architecture
• Built with Django + Node.js.
• Running on Heroku, S3, EC2, SES, Route 53.
• App server, Payment Server + Wallet.
• Supported by Trello and Google Hangouts.

14. Min.io: Where to?
• See what happens. Promote, market, get
feedback, iterate.
• Support altcoins?
• Deterministic address generation.
