Shared Ledger Technology and the snapshot problem

Chris Hamilton — Wed, 20 Apr 2016 23:25:07 +0000

I’ve talked before about how user trust in service providers is still necessary for Shared Ledger Technology (SLT), but I think the question about trust in central third parties is harder to analyse. By “central third party” I mean anyone…

Why Shared Ledger Technology won’t free us from human fallibility

In my previous post, I discussed Bitcoin’s desire to remove trust from the payments process. I now want to look at the nature of financial trust: What does it mean to say we “trust” a third party? Is trust of…

We need to talk about Bitcoin’s trust issues

I recently tackled Satoshi Nakamoto’s original Bitcoin text, which has mythical status amongst devotees of shared ledger technology. It is a paragon of clarity on what Bitcoin is really all about. According to its spiritual father, the purpose of Bitcoin…

Towards a sensible dialogue on cybercurrencies

If you work in payments, you will for sure have been part of a Bitcoin debate in the last 12 months. Until recently, such discussions usually took one of two forms: they were either pep rallies or exorcisms. Actually, the most entertaining events in my memory happened when participants turned up expecting one, and got the other.

A brief terminological note: “cybercurrencies” in this context means any open protocol for the retention and transfer of value where the attribution of value, and the recognition of ownership, does not derive from or rely on a national currency. There are many ways of doing this, including open loyalty schemes, game currency platforms and algorithmic currencies, but the best known is Bitcoin.

Payments World USA

In April, I took a quick trip to Disney World...well, kind of. The annual conference of NACHA, APCA's equivalent body in the USA, was held at Disney World's home: Orlando, Florida. Around 2,200 bankers turned up to hear three days of presentations on the state of US payments - and possibly catch a few rides. I hope they had some fun amongst the work, because these are stressful times for US payment providers. Having weathered the GFC with tightened budgets, US bankers are acutely conscious of new payments system developments in other countries and pressure from the US Federal Reserve to follow suit or be left behind; but they are a long way from agreeing amongst themselves what is to be done, and who will pay. My small contribution was to outline the policy logic behind Australia's New Payments Platform (NPP) proposal as a comparative example. There was much interest.

The future of money

Believe it or not, the current US Presidential nomination process has thrown up a passionate debate about the nature of money, and particularly whether it is 'sound' or not. Voters are frustrated and fearful about the economy. Politicians (with no economics training) are arguing that in these uncertain times we need a currency backed by something 'real' like gold.

This seems oddly backward-looking in the era of the internet. It begs a question: what sort of money do we need to fuel the economy of the 21st century?
