Montreal scaling Bitcoin workshop recap.

[jonald_fyookball]

maybe you should tell all merchants who use bitpay to process and convert BTC payments they are at risk of being cheated.

you're being overly paranoid, and your ivory tower is really high.

Of course they are at risk. There is always a risk.

Bitcoin is made to be decentralized, apolitical, trustless.
 

I think you missed his point.

SPV is trivially risky compared to payment processers.  And even those are limited risk.  If they don't settle at the end of the day,
you've lost a day's revenue.

Interesting image.

If you look carefully at the graph (B) DECENTRALIZED, you may notice it may not be as decentralized as it looks: look carefully at the middle node, it's a single point of failure. Take him away and the "Decentralized" network is disrupted.

Decentralization is very difficult to define and mesure, and a "decentralized" system may seem decentralized but actually contain hidden points of failure.

Well spotted. You are absolutely right. I missed that.   It's a clustered topology which is a form of centralised network.

The image in B is not really decentralized, a decentralized network would have many connections between those small local hubs, but the image has only one such connection between the top 2 nodes. This terrible picture shows that its author does not really know what he is talking about
