Segwit adoption skyrockets over past week!



https://twitter.com/RedditBTC/status/1177880651292381184?s=20

More people to enjoy their bitcoin transactions much faster and also little bit of reduction in their transaction fee.

What other benefit could we get from adopting to segwit?

Any techies.

Well there is also an increased risk of suddenly losing all your coins.

No, there's not. Its never happened. No one has carried out an "anyone can spend" attack because it can't be done.

Mishaps in the past were due to an improper implementation of Segwit by an exchange or wallet, not Segwit itself. The risk now is zero unless you are using deprecated software.

For more on why there's no such thing as an "anyone can spend" attack:

The claim goes roughly like this:

There would be a growing incentive for a 51 % attack as the number of SegWit outputs accumulates. The attack would be to “disable” SegWit, reinterpret SegWit scripts as “anyone-can-spend”, and then steal all SegWit coins.

This was repeated numerous times on Reddit and rehashed by parties like nChain or Bitcoin.com.
A transaction is valid, if nothing in the combined script triggers a failure and the top stack item is non-zero. Scripts are considered as “anyone-can-spend”, if there is no condition attached to be fulfilled for the script execution.

Segregated Witness uses empty scriptSigs (when not using P2SH) and scriptPubKeys that consists of a 1-byte push opcode for 0 to 16, indicating the witness program version, followed by a data push between 2 and 40 bytes for the witness program. The witness program is then interpreted, executed and enforced by Segregated Witness aware software.

Any miner that stops enforcing Segregated Witness rules and starts to create invalid blocks, namely blocks falsely spending coins that require a witness program to be executed, would be partitioned off the network by other miners and users.

But let’s assume the worst case for a moment: 51 % or more of all miners go rogue and start to create invalid blocks by not enforcing Segregated Witness rules. Honest miners would still consider these blocks as invalid and build their own valid chain, but given that they are a minority, at some point they end up as shorter chain.

There would then be two separate chains, one from the rogue miners, and one from the honest miners. They have hard forked and the chains are no longer compatible.

Other participants in the network, in particular full nodes, do not follow the longest chain per se, but the longest chain they consider as valid. Full node users would then also consider the chain from the rogue miners as invalid, and follow the chain of the honest miners, which enforce Segregated Witness rules. Segregated Witness scripts are not vulnerable.

It may be worth to note that nodes running old software, namely software that isn’t Segregated Witness aware, would indeed follow the rogue chain in this scenario. This is expected and inherently the case, given that Segregated Witness is a soft fork.

Why is that functionality even there?

It's there so uneducated people like you can spread FUD. Even a child would understand that anyone-can-spend bullshit attack isn't possible after 2 years of Segwit-related talk.

[mindrust]

I wonder which moron came up with the name "anyone can spend". This sounds like it is from a moron of the past, JonaldFuckface.

I know it seems bleak Mayor.

hang in there buddy

That's not an answer. Why is it there? What useful function does it serve?

If you own a fair amount of bitcoin, you should definitely educate yourself on the matter. There's loads of information on it out there.

[Dabs]

There are several native segwit addresses with at least 1000 corns in them. Why isn't anyone else spending them? (No one else can.)

Timestamps have value. @roach, people aren't replying to you or even read your response because a lot of them have you on ignore. Apparently.

[Arriemoller]

Caring about the environment is for pussies. You're supposed to eat raw meat and fart diesel fumes if you want to be a right wing Alpha in this day and age. If you want to prove yourself go bleach a coral reef and burn down a rain forest.

Hey. Don't denigrate raw meat.

I love raw meat and I'm not some knuckle-walking conservative redneck. Not some politically correct goody-two-shoes liberal either.

Alphas have better things to do with their time than waste it on politics.

Just call that raw meat "steak tartare" and you become a stuckup, white-wine-drinking card-carrying member of the liberal elite.

Can you just liquefy it?

Well yes, at very high pressures.

The current (type IV, the type V tanks are experimental) tanks hold it at 700bar, that is 10,000psi...  ...

I started wondering what it would take to liquefy and store elemental hydrogen
according to the wikipedia liquid hydrogen page,
"To exist as a liquid, H2 must be cooled below hydrogen's critical point of 33 K."
So you can't store and ship liquid hydrogen on an industrial scale.
I read somewhere that current research and development aims to store hydrogen by infusing it into other materials, I don't remember what exactly, but maybe a polymer or something.

In other news,

You got to know when to hodl
Know when to fodl
Know when to wakl away...

(sung to the tune of The Gambler, by Kenny Rogers)

I think you might be misinformed, there are hydrogen gas stations in Norway and other places in Europe for hydrogen cars. One of them exploded due to a an incorrectly mounted plug in a high-pressure storage tank and they are, as far as I know, closed for the moment. But they are out there.  Toyota planned to sell around runt 20 Mirai hydrogen cars in Norway this year, but the plans are on hold for the moment.

It's curious that all the people who claim to have all the answers refuse to share them. It wasn't like this pre-segwit.

This is why people are still arguing. Two years of insults and obfuscation does not constitute debate.

Anyone-can-spend: Why am I here? What's my purpose?

Your role for today at least has been to remind us to brush our teeth. I normally scrape them once a month and put the residue in a bucket by me bed, that's if I haven't spontaneously formed a plaque ball and gobbed it out on the bus, but you've inspired me to find a toothbrush in a dumpster somewhere.

Sheesh! dude go to a dentist. You have a D in your username at least... get one irl lol

This is getting ugly

your mom is ugly

Your net worth is ugly but hey, at least we have something ugly in common?

Relax. I am ugly.

I think Schlitzie was a guy.

He was. Dresses were 'supposedly' helpful with his incontinence.

your mom is ugly

Hey. Leave Schlitzie alone.

I met her back in the early 1960s when she was still working the freak shows.

She was actually quite the charmer (for a microcephalic).

Probably smarter than some of the trolls here too.

You sir. You are older than my father!

..imagine being so poor you can't even spell Bentley

You mean Bent Lee?

Maybe whoever is behind this fuckery is trying to scare as many noobs as possible.

We may still wake up tomorrow to $9k vegeta memes.

Tomorrow has come and gone.. sadly. $9k still nowhere to be seen.


To me the crash seems like a case of someone buying into BTC in huge volumes. Probably some institutional investor, government or whatever. And a different group / entity wiped that entire gain after June 2019 out of the market by dumping hard.

These two events might have been marked by extreme criticism and extreme appreciation of BTC by someone big.

Y'all can pretty much guess which "big head" I am referring to..

[gentlemand]

Sheesh! dude go to a dentist. You have a D in your username at least... get one irl lol

I am British.

I usually subcontract that to whomever I find in the nearest dumpster.

I don't know about you guys, but I'm about ready to see a $1000 USD dildo.

Yes.  A green one. Within 72 hours.
