3. My Background / Interests:
● NXT core developer (alias transfer, voting
system, etc)
● Blockchain-based applications advocate
(cryptamail, secureae, etc)
● Distributed Systems Development
● Functional Programming
● Finite State Systems & Model Checking

4. This talk is about
● Decentralized Exchanges
● IPOs on DEs
● Distributed Shareholders Voting
● Dividends
● Smart Contracts
● Virtual Corporations
● Distributed Autonomous Corporations

5. Decentralized Exchanges
● NXT & its clones(NAE, NEM, NTX, NFD,NAS...)
● Bitshares
● Counterparty

6. IPO on Decentralized Exchange
● + Low cost
● + Could be backed by anything(a company, a
picture, a nonsense)
● - As a result, a lot of thrash comes in

7. IPO Example: Coinomat
● Backed by quickly growing online business
● Weekly dividends
● Revenue stats open, but not verified by 3rd
party or in trustless way
●
● Todo: picture

8. IPO Example: BgCaffee
● Backed by offline business
● Buongiorno Caffe opened November 2013 in
Pretoria, South Africa
● “The assets sold will always represent 50% of the total
profit of all shops for their lifetime and no additional
assets will be sold without the addition of a new shop
or business unit that generates profit, that is our
guarantee”
● No trustless or 3rd party control though

9. IPO Example: NXTdrop
● Assets backed by paintings
● No any hard profit promises
● (todo: picture)

10. IPO Example: BadPonzi
Ponzi scheme guaranteed, lol:
“Buy some “Bad Ponzi Token” (BPT) and I will spend 3
times a week 70% of the revenue to the asset holders
according to their shares.”

11. Fund Raising
● Loans
● Angel & Venture Capital
● Crowdfunding
● Distributed Assets Exchanges!

12. A Business Without Venture Capital
● Publish business plan
● Issue assets
● Raise funds
● Get shareholders feedback/opinion via voting
● Pay dividends via blockchain

13. Voting via Blockchain
● Distributed
● Decentralized(anybody could start a poll)
● Cheap
● Results are public & verifiable
● Example in my article: “Shareholders Meeting
via Blockchain in 20 Lines of Code”

14. Dividends: Coinomat
● (todo: picture here)

15. Guarantees
● Enforced by Law
● Enforced by other trusted party
● Trustless enforcement

16. Dividends Promise (SecureAE v. 0.1)
{
"contents" : "clause",
"ver" : 1,
"assetId" : 565748484,
"datetime_start_utc" : "Aug-16-2014 11:59",
"datetime_end_utc" : "Sep-16-2014 11:59",
"sum" : 500
}

17. Trustless Smart Contracts
Some kind of scripting over blockchain needed:
e.g. Ethereum, cfb's Smart Contracts, ciyam's
AT etc

18. Virtual Corporations
● Special types of accounts
● Dedicated operations: incorporations,
dividends, board polls, corporate statements
● Law?

19. Distributed Autonomous Corporations
● NameCoin
● NXT AE
● A driver-less car
● A currency itself
●
(todo: some pictures)

20. DACs + Smart Contracts
That would be funny!

21. Open Problems
● Blokchain bloating
● Blockchain scripting: bloating,
computational requirements, halting
problem
● Formal semantics of statements

22. Conclusions
So many exciting things we already
have: decentralized exchanges, new
models of fundraising, distributed
shareholders meetings, simple
contracts & few DACs!

23. Conclusions
Hard challenges to complete: formal
contracts, trustless guarantees,
sophisticated DACs
