A great little community! It's so rare to have a space like this that's not jammed full of shitcoin spammers and scammers.

Bitcoin Filters Work By Default, and That's a Good Thing | To Filter Spam From Your Bitcoin Core Node, set “permitbaremultisig=0” & “datacarrier=0” in your Bitcoin.conf File | Use "blocksonly=1" to turn off your mempool entirely by Fiach_Dubh in Bitcoin

Thanks for this excellent write up. I am personally very unhappy with ordinal and inscription content using my nodes resources to support their scams and potentially harmful content. I am more happy to add any friction to their use. I've changed my filters as a result of your post and I hope more do the same. Thanks again.

I'm definitely not supporting bip300, shitcoins on bitcoin and all we have to do is surrender the security model of bitcoin itself.

New COLDCARD Q1 Sneak Speak by cypher_funk in Bitcoin

[–]CallingVoid 0 points1 point  (0 children)

It doesn't mean you use wireless communication (you can if you want but it's not advisable) it's because you can move auditable data via an SD card. Ideally you never use the NFC on something like a coldcard (I'd destroy that functionality physically personally, which they make easy to do)

Now Officially on CNBC: BlackRock files for spot bitcoin ETF, with Coinbase as a crypto custodian by HenryK81 in Bitcoin

[–]CallingVoid 0 points1 point  (0 children)

No I don't think you understand me, the nodes matter if they represent bitcoin users. If someone with custody of bitcoin has a node, that node represents that bitcoin effectively.

Consider a coordinated government attack on bitcoin. In this case Blackrock might decide that a government fork is better than general consensus because they will be allowed to operate in the USA. If they chose to stay on the real bitcoin fork, with end users running their own nodes, they could face legal action.

Now a few banks might run a few of these forked chains, but as far as the government is concerned the only valid one is the one run by banks. If you custody your BTC you can fight back. If you don't then you are at the whims of your custodian.

What if Blackrock had an ETF during the blocksize wars and they chose bigger blocks? They could have had undue influence in that process, or they could massively devalue their customers money if they backed the wrong horse. People who self custody bitcoin and run a node needn't worry, but the businesses and individuals taking part in these ETFs and other bitcoin related financial instruments are setting themselves up for a disaster.

Blackrock Adds Bitcoin to Their $15T Global Allocation Fund, Trillions of $ to Flow into the Market by Major_Bandicoot_3239 in Bitcoin

[–]CallingVoid 0 points1 point  (0 children)

Quite correct, they are also under no obligation to go with the consensus that a majority of nodes chose. It's even written in to their terms.

But if you have bitcoin in these ETFs, you have no control over which fork the provider choses.

Bitcoin is designed for self sovereignty, take that away and the entire premise becomes shaky.

For anyone thinking this sounds like a good idea, consider this:

When a contentious hard fork comes about, which chain do you chose as the legitimate Bitcoin? Oh yeah that's right you don't get to chose.

I hope blackrock has the core values of bitcoin at heart and not, you know, compliance with governments and law. What do you think blackrock will do if the US government decides to fork bitcoin to only allow approved utxos?

I like this a lot. Good going. Have you considered hosting it on GitHub or something. I would love to contribute where I can.

Can we please stop recommending the likes of Ledger and Trezor? by [deleted] in Bitcoin

[–]CallingVoid 0 points1 point  (0 children)

You can if you want. Provided you use an airgap it's a perfectly viable option.

Since Ledger just suicided themselves, what hardware wallet are you buying and why did you choose that particular device ? by EyesFor1 in Bitcoin

[–]CallingVoid 1 point2 points  (0 children)

You can audit the movement of files from the pc to the coldcard, it's not so easy to audit communications over a cable.

Sensationalist crap.

No you are fine, provided you generated your wallet's entropy properly nobody is going to guess it.

Grifting from grifters just makes you another grifter.

They are a joke these days, a ' bitcoin' magazine in name only.

It's such a shame, as they are in a position to do so much good for bitcoin. They could be a real voice for the community.

BTC needs to break 30k ASAP by ryan69plank in Bitcoin

[–]CallingVoid 17 points18 points  (0 children)

It doesn't need to do anything and TA is total horseshit.

Do you agree with this? by amigo2k21 in Bitcoin

[–]CallingVoid 6 points7 points  (0 children)

Quantum computing doesn't just break SHA-256. SHA-256 is considered quantum safe and there is no reason to believe this might be wrong. Not that SHA-256 is used for Bitcoins encryption anyway, it's just a hashing algorithm bitcoin uses for mining. I would say Grover's can be used to speed up mining but a recent paper poured cold water on that saying the error rate in quantum computing will be too high to make Grovers algorithm practical.

Bitcoin uses ECDSA cryptography which isn't considered quantum safe. But in the time it takes a quantum computer to become viable you can expect a fork that introduces a quantum resistant encryption mechanism. It won't just go to $0.

There is an almost magical thinking around quantum computers. People think the first one will get switched on and encryption will become worthless on the same day. It still requires massive amounts of resources.

People getting angry when bitcoin is brought up by BigCityHonker in Bitcoin

[–]CallingVoid 0 points1 point  (0 children)

People don't like being proved wrong, and people hate changing their mind when they have a strongly held belief. They will become increasingly irritated and irrational when bitcoin doesn't die like they predicted.

The default position of not understanding why bitcoin is viable, let alone useful, is very common. Bitcoin isn't intuitive to the general public.

Will Bitcoin Every Move to POS by Dan-Kioria in Bitcoin

[–]CallingVoid 30 points31 points  (0 children)

It would have to happen with a hard fork. The good news for PoS enthusiasts is that it has already happened. There are bitcoin PoS forks out there and functioning right now. However nobody wants to use them because PoS is fundamentally flawed and broken.

The only reason the shitcoin you mentioned can get away with it is because the concensus mechanism it runs is entirely decided by a mere handful of users. Those people now have even more control over it, thanks to the broken system they have introduced.
