### Bitcoin Fees vs Supply and Demand

Continuing from my previous post on historical Bitcoin fees… Obviously history is fun and all, but it’s safe to say that working out what’s going on now is usually far more interesting and useful. But what’s going on now is… complicated. First, as was established in the previous post, most transactions are still paying 0.1 […]

### Bitcoin Fees in History

Prior to Christmas, Rusty did an interesting post on bitcoin fees which I thought warranted more investigation. My first go involved some python parsing of bitcoin-cli results; which was slow, and as it turned out inaccurate — bitcoin-cli returns figures denominated in bitcoin with 8 digits after the decimal point, and python happily rounds that […]

### The Root of all Evil

He’s right: people do make that argument, and it’s silly. It’s especially silly because people already do it for a profit, and even sillier […]

### Spam and Ecash Risks

One risk of solving spam (by doing cool ecash stuff, or by any other means) is that you might be attacked by people who don’t want it solved. I underestimated both the enemy’s level of sophistication, and also the enemy’s level of brute malevolence. I always knew that spammers had no principals and no ethics, […]

### Measures for Bank Efficiency

Each currency has to have a single dedicated bank to handle transactions. It requires a database containing an entry for every transaction that’s taken place. Each transaction needs to do a single element lookup from that database, and there shouldn’t be any locality of reference. Your storage requirements are O(T), and your transaction overhead is […]
