7. #PunkMoney “@Bob I promise to buy you a beer. Expires in 1 week. NT. #PunkMoney” – @Sally An expiry Non-transferable

8. #PunkMoney This syntax makes @Sally’s tweet #PunkMoney. What now?

9. #PunkMoney Beer time…

10. #PunkMoney Bob enjoys his beer, so he redeems Sally’s promise.

11. #PunkMoney He does this by favouriting Sally’s original tweet…

12. #PunkMoney This gesture is a public way for Bob to say ‘thanks’ for his beer.

16. #PunkMoney The system depends entirely on trust. How do you make this visible?

17. #PunkMoney Users can create a Twitter list, called punkmoney-trusted, and put the people they trust in it.

18. #PunkMoney The overlapping lists can be crawled and represented as a trust-net. This shows us who trusts who.

19. #PunkMoney #PunkMoney is defined by a set of simple protocols and gestures. Nobody owns them, and anyone can use them.

20. #PunkMoney However, it gets difficult for users to keep track of all of this using Twitter alone (although it is possible.) We need a way to track and record #PunkMoney activity.

21. #PunkMoney The #PunkMoney Tracker is an open source tool which anyone can deploy to a live server. It collects tweets with the #PunkMoney hashtag, interprets and records them. www.punkmoney.org

22. #PunkMoney It makes it easy to find out about and follow the history of any #PunkMoney promise. www.punkmoney.org

23. #PunkMoney It also features a printer, for conveniently creating #PunkMoney statements. www.punkmoney.org

24. #PunkMoney Finally, the TrustNet provides a nodal graph of the current state of the #PunkMoney trust network. www.punkmoney.org

25. #PunkMoney #PunkMoney has some special characteristics as money…

26. #PunkMoney It is fully decentralised. There is no authority for issuing it, or for authorising and recording transactions.

27. #PunkMoney It has no unit of account. It’s designed to encourage the flow of gifts, rather than market-based transactions.

28. #PunkMoney It does not have very strong security – a user’s identity is only as safe as their Twitter account. It is casual money.

29. #PunkMoney The #PunkMoney tracker is under active development, and has a growing numbers of users and supporters.

30. #PunkMoney The vision is of a fully decentralised money network for friends, communities and movements.
