OP did actually host a tracker. "I then started the tracker. After about an hour, it peaked at about 1.7 million distinct torrents across 3.1 million peers!"

`for char in message: encrypted_char = ord(char) ^ (shared_secret[0] % 256)` This is not real encryption, it picks only one byte of shared secret and XORs it into the plaintext. Therefore, there are only 256 possible decryption keys to chec

It was a one-way collaboration, in that we referenced their discoveries and code such as LattiCG https://github.com/mjtb49/LattiCG , but they were unaware of anything we were doing until now. https://twitter.

Yes, absolutely :) that's why we went to FitMC to make the video, he always delivers.

No that's not at all how this works. The iterator could "return" a boolean by passing a boolean to "yield". The return value of "yield" just indicates if the generator should continue, or stop because the

Some mistake or miscommunication happened there, as Wikipedia does have a policy that people can be cited for information about themselves, the policy is called SELFSOURCE. See: https://en.wikipedia.org/wiki/WP:SELFSOUR

Well it's a continuous process: today the fees make up maybe three percent of revenue, but that fluctuates as transaction space demand changes, and as the coinbase halves every few years. But your point is good - miners are not really

I've heard the metaphor that "writing your ledgers in pen instead of pencil doesn't make transactions irreversible" - meaning that in the same sense, actions on the blockchain could be coded to be irreversible. The diffe

Why do you think it all comes down to that? Clearly there's much more to it. For example, cryptocurrencies with those two properties you mentioned are a dime a dozen. I could make one right now by git cloning bitcoin, changing some pro

I don't think that's true, fees are not proportional to that. Fees compete for a finite and precise limited space in blocks. There's no limit to how high fees could grow in this competition, because only the 7 most lucrative

No need to speculate on how big or small the gaps may be, the article looks at the actual random gap values used on Wikipedia. Quote: "The least viewed article in the sample, Erygia sigillata, has a page_random value of 0.500764585777.

If I remember correctly, for ZFS it was some stuff about cache size and RAM usage, since we were in a VM and couldn't be too greedy. Something about a NVME drive needing slightly different settings. I didn't spend much time on thi

For tracking, the spatial resolution was 1 chunk, which is 16 by 16 blocks, and the temporal resolution was 1 second. So, we have a few billion rows of tracking data for every player, localizing them to roughly that distance, roughly once a
