@Daniel__Street The fraud doxxed himself.

@BitcoinDict Bitcoin SV can not enable unbounded loops, so it is not Turing-complete (it relies on external transaction chaining).

@kareem_carr Science is a public good, so from an economic perspective, it doesn’t matter who does it or where it is done (rationally, we want science to take place, but funded by others).

@cryptoswede1 @PacArtCollect @CsTominaga @hascendp6 Craig is not Satoshi, but a fraud. Bitcoin is decentralised in the sense that the nodes do not trust each other, or exert control over one another. The protocol (consensus rules) does not need to be fixed, a central authority is needed to decide if, how and when it should change.

[Martin Sewell @MartinSewell]

@cryptoswede1 Certainly, centralisation is an emergent behaviour driven by economic forces. But Satoshi’s goal was to build a decentralised electronic payment system. Satoshi was not an economist.

[Martin Sewell @MartinSewell]

@PacArtCollect @CsTominaga @hascendp6 A system is said to be decentralised if it lacks a central authority. Satoshi is describing how a decentralised system (Bitcoin) might scale.

[Martin Sewell @MartinSewell]

@CsTominaga @hascendp6 @PacArtCollect Satoshi’s goal was to enable trusted electronic transfer of value between peers without recourse to a trusted third party. This meant building an electronic payment system that lacks a central authority. In other words, decentralisation was the whole point.

[Martin Sewell @MartinSewell]

@hascendp6 @PacArtCollect @CsTominaga This is the strongest evidence that Craig doesn’t understand Bitcoin at the most fundamental level. Of course, decentralisation was the whole point.

[Martin Sewell @MartinSewell]

@CsTominaga A transaction tax would reduce liquidity, increase volatility, increase the cost of capital, reduce growth in productivity, shrink the economy, reduce wages and reduce total tax revenue.

@ButcherBallyhoo @PeterRizun Bitcoin has never been Turing-complete.

@TimJSwan @PeterRizun By design, Bitcoin is not Turing-complete. Satoshi obviously knew this.

Pain in my right quad slowed me down and made me consider quitting, but thankfully I recovered.

@GlobalPHObserv Countries near the source of the pandemic (China/Southeast Asia) likely had greater pre-existing immunity.

@kareem_carr Not necessarily. It depends what question they are trying to answer.
