Bitcoin Q&A: Governments vs. Proof-of-Work or Proof-of-Stake

If multiple governments collaborated, could they launch a 51% attack on Bitcoin? If all it takes to attack a proof-of-work (PoW) network is enough electricity, wouldn't you want the game theory of delegated proof-of-stake (DPoS), or a hybrid system? Could chainlocks prevent 51% attacks?

Finally a reviewer who actually understands. Thank you very much.

You're the GOAT when it comes to bitcoin evangelism brother. Thank you for your service!

There’s the closest we as mortals with knowledge on our mortal levels will get to truth of where things are with things. Thats because he explained his view clearly and backed it up with logic. Good man.

Can't believe so many people lose sleep and worry sick about BTC getting a 51% attack. By who? The Dept of Agriculture?

Thanks for the comments on Dash! Impressed to see you went deep and understand it. More people would do well to do the same.

Thank you for posting! Hoping for some guidance: My Trust Wallet has some Tether, and I possess the seedphrase: -clean- -party- -soccer- -advance- -audit- -clean- -evil- -finish -tonight- -involve- -whip- -action-. Could you suggest how should I proceed with transferring them to Bybit?

Andreas how - in easy yet convincing way explain to somebody how bitcoin is beeing developed - a friend argued with me that bitcoin is centralized because there is a core development team and therefore they can implement changes into bitcoin structure and they have the power over other community members. What is the explanation to that? Please!

[angelmendez]

@aantonop I like to know what would be the impact of quantum computing in crypto (general) and the bitcoin space?

[ziomanzo]

you're so sarcasticly funny man 👌

[miblish]

Why can't the NSA simply develop software to sniff out nodes and then knock them offline?

[gaeldesmontagnesnoires]

What if Governments printed fiat without declaring that they are??? who could even tell that they did?

[SanktGallus]

We need proof of shit for xrp, bch, bsv !

[fliteshare]

Governments are not at risk from crypto currencies.
It is the banking world that is being disrupted.

I know you travel a lot but, could you please buy quality portable camera and microphone please ? Especially microphone. Thank you.

[steelhorses]

Is the BTC network at risk of mass attacks on the node network? Either by ddos or putting up large numbers of corrupt nodes?

[George-eepp]

Really great video Andreas I learn so much from watching you.
Could you please make a video or give your thoughts on a multi blockchain structure, such as Komodo, that uses Bitcoins hash rate as a check point to secure all the blockchains within the ecosystem.
Keep up the awesome work my friend!

[edwardeduardus]

If gouvernments or whatever organisation collaborates to archieve a 51+% hashing power, don't you also expect opposition parties will try to reduce it by unite and fight against it? Digital democracy, I would call it!

[emmsee]

All about PoS, what are your thoughts on Algorand's PurePoS Andreas? Staking ROI's look fantastic...

[TiagoCanto]

One big problem about Proof-of-Stake currencies, which few people speak on, is that it's impossible implement a full level of privacy on layer 1, because the amounts in the addresses need to be visible.

[CharIie]

Question: is the block proof arbitrary? How can an address be safe for a billion years of attacks, while a block needs x amounts of terra hashes to generate safely. Could the network itself just generate the blocks, and hand out the coins randomly in a lottery styled manner? Or by any other process, say solving a captcha or something other non electricity consuming
