Bitcoin, Blockchain Technology, and Crypto-Currency

There has been lots of chatter lately about bitcoin, blockchain technology, and crypto-currency. Everyone, including me, is trying to wrap their head around it all. This is what I’ve come up with so far:

  1. Bitcoin is a virtual commodity that is created by running some obscure algorithm. The people who get rewarded are the “miners” who burn up enormous amounts of computer time and electricity to create Bitcoin. That makes it akin to mining gold or silver—not a very useful pursuit, and like any commodity, people will prefer to use it as a savings medium or hedge against inflation rather than circulating it as a currency. Bitcoin is NOT the answer to the money problem.
  2. The important thing about blockchain technology is what it can do, what functions it can perform. You hear a lot about “smart contracts” and a secure trail of transactions. It seems to be something that is needed when using digital forms of contracts and transactions conducted over the internet, but provides no new functions compared to what has always been done with paper trails and records, but maybe I’m missing something.
  3. The term “crypto-currency” is ill defined and there is much confusion about the characteristics of such a currency and what it can achieve.
  4. The fundamental principles of reciprocal exchange still hold. The substance of a currency or payment medium is CREDIT. Claims still need to be authenticated and promises need to be guaranteed.

My grand, audacious vision is this:


What they might have is skills, abilities, products, services and credit that is advanced by a circle of people who know them and trust that they are ready, willing, and able to deliver value on demand in the near term.

I have argued that the truly disruptive technology of exchange is a global network of small credit-clearing circles that provide “a means of payment that is locally based and controlled yet globally useful. It makes money and banks, as we’ve known them, obsolete.

My talk in Malaysia in October at the International Forum on Inclusive Wealth ( will be on that topic and will build upon the framework that I laid out in my book chapter, –t.h.g.

Complimentary Currency Systems: Richard Logie at TEDxLeeds

Richard Logie has been for a long time one of the leaders in the commercial  barter industry. As owner and operator of The Business Exchange in Scotland and developer of GETS, a moneyless trading platform, Richard has a wealth of knowledge about moneyless exchange in general. His presentation below provides a valuable learning tool for anyone, either in the entrepreneurial realm or at the grassroots level, who is starting or operating a currency or exchange system.

Please pay particular attention to the way in which Richard determines the credit lines to be provided to members’ accounts, the list of advantages that membership in a credit clearing exchange provides, and the elements that need to be standardized in order for exchanges to be effectively networked together.–t.h.g.

Cyclos, worth another look??

I Just received a message from one of my advisee groups on the west coast. They are seriously considering Cyclos as the platform for their local exchange system.

Here is what they say:

Cyclos offers a complete Open-Source on-line banking system with additional modules such as e-commerce and communication tools. Check this out at

The objective of the project is to develop open source complementary currency software that is easy to use and maintain, flexible, secure, and highly customizable. The Cyclos structure is entirely dynamic.

This means that it is possible to ‘build’ a monetary system from scratch. Organizations that want a standard system can use the default database that comes with basic configurations and can be easily enhanced. Cyclos is used for mutual credit systems like LETS, Barter systems, administration of Micro credits or remittances, Time banks and backed currency systems such as a C3 (consumer and commerce circuit). Cyclos just started to be used as a back-end for mobile banking services in Africa, and various Universities are studying the possibility to use Cyclos as a campus payment system.

It seems that the newest version of Cyclos may have the functionality, ease of use, and customizability that we have been looking for.

I’d be interested to see or hear expert reviews and people’s actual experience with using the Cyclos platform. Please send them as a comment to this post.
