Proton Mail CEO Calls New Address Verification Feature 'Blockchain in a Very Pure Form' (tech.slashdot.org)

Proton Mail, the leading privacy-focused email service, is making its first foray into blockchain technology with Key Transparency, which will allow users to verify email addresses. From a report: In an interview with Fortune, CEO and founder Andy Yen made clear that although the new feature uses blockchain, the key technology...

Voting is another concept that would become unhackable overnight

No. Voting on the blockchain is an even worse idea than money on the blockchain.

In many cases, there are good reasons why these things are done they way they are. I have yet to see a software system that is better at preventing voter fraud than humans looking at your government-issued ID at a poll site and humans overseeing other humans manually counting votes.

A single actor might be able to commit voter fraud in the order of dozes or hundreds of votes perhaps but with a digital voting system based on blockchain, they could do so on the order of thousands or even millions by compromising end-user devices used for voting or buy enough work/stake/whatever to perform a 51% attack.

Same goes for money btw. Our current system is by far not a perfect one but removing the ability for governments to i.e. freeze accounts of bad actors is not a boon.

nobody’s made a solution that is simple and effective

This one isn’t that either by the looks of it but it’s certainly a problem where something like blockchain could provide a solution.

This is false. Protonmail has supported Web Key Discovery for external domains since 2019: proton.me/blog/security-updates-2019

So PM claims it has on the order of 10^8 users. Let’s assume each user has one email address with one public ed25519 key, both of which are likely false.

Each key is 32Byte; 32B * 10^8 = 3.2GB.

Could someone do the math how much fiat it’d take to store such an enormous amount of data on the Ethereum or monero blockchains?

Not just read but modify even.

I don’t know about timeshift but it appears to have a configuration tab for snapper.

except for hdds without cache

The “cache” on HDDs is extremely tiny. Maybe a few seconds worth of sequential access at max. It does not exist to cache significant amounts of data for much longer than that.

At the sizes at which bcache is used, you could permanently hold almost all of your performance-critical data on flash storage while having enough space for tonnes of performance-uncritical data; all in the same storage “package”.

Note that bcache and bcachefs are different things. The latter is extremely new and not ready for “production” yet. This post is about bcache.
