(lets call SIGHASH_ANYONECANPAY ACP for short) ACP allows you to only sign your own input and ignore the rest. [input_ACP] [output_1, output_2] so if others can add their inputs to this transaction like so: [input_ACP, input_1, input_2] [output_1, output_2] or [input_1, input_2, input_ACP, input_3] [output_1, output_2] now this works fine with ALL and NONE since the index of the input_ACP doesn't matter at all. but the problem is if it was signed with SINGLE: [input_ACP] [output_1, output_2] in this transaction you only sign output_1 from outputs since input_ACP index is 0. and if someone added their input like this: [input_ACP, input_1] [output_1, output_2] it works fine. but if someone added their input like this: [input_1, input_ACP] [output_1, output_2] then input_ACP signature would become invalid since now the index of it is 1 and should have signed output_2 instead! so the question is, am i understanding the way SINGLE | ACP signhash works and is this a problem or am i mistaken? |

i have been learning more about how transactions are signed and already finished all output types but all with SIGHASH_ALL. i feel like all the documentations are lacking when it comes to different SIGHASH types.
bitcoin.org has a "transaction guide" that explains what is signed with each type but i can not find any actual examples anywhere to understand what it means and see it on an actual transaction on the blockchain.
are transactions signed with these types even final/valid?
what is the scriptpub of the outputs they are signing?

i just found out about it but apparently this has been the plan for some time now. it seems like it was first for publishers to gather BAT tokens and now it is to be enforcd for anybody who wants to use the wallet (Brave Rewards).  it is worth noting that KYC is not requires if you use it as a browser but the question rises, why would you want to use it after this and when there are good browsers like Firefox available which is the original code of this project? |

i came across this new change in bitcoin core's next version (0.19) which they are planning to disable bloom filters by default. you can read about it in this mail: https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2019-July/017145.html there is also the link to the PR and the relative discussions. i was wondering which one of the current existing SPV clients rely on boom filters to work? |

it seems like the "hype" has died as they are now done pumping the shitcoin known as BSV but in case you missed it US copyright office made an official announcement saying they do not recognize anybody, specifically Craig Wright, as Satoshi Nakamoto despite what lots of clickbait news sites have been saying a day ago when the shitcoin pump began. link: https://www.copyright.gov/press-media-info/press-updates.html |

a while ago i started a topic here talking about the FOMO that is going to occur when the price rise begins. here is the topic: https://bitcointalk.org/index.php?topic=5108231.0although there weren't that many votes but it seems like most people got the right answer (the shoot up to $5k) which was the FOMO that i was talking about there. the initial leg up which shoots price upwards $1000 in a couple of hours. now another question. what do you think the next leg up is going to be? maybe you think there is no FOMO and only a slow rise this time? lets see how the results are going to be this time... |

recently we have seen a small preview of what the FOMO (fear of missing out) can look like in bitcoin market when the rise starts. we have also seen it many times when the reversals happen and generally whenever there is a rise.
so considering the current situation where most investors are scared, how big do you think the FOMO is going to be when the rises start?

i always say that the best way of learning "how to trade" is to start doing it yourself. you won't learn anything by following others, reading stuff online and doing nothing. you have to get your hands dirty.
one of the good things about cryptocurrency market is that the exchanges allow you to start trading with a small amount. there are even exchanges out there that allow orders as small as 0.00001000BTC which is about 6 US cents! you can invest about $10 and start your trading journey and gain experience.
so why NOW is the best time?
it is the best time because prices are falling and there isn't any pumps going on in the altcoin market. for instance if you have started trading last year, if you closed your eye and chose an altcoin to invest in then no matter what you chose it would have gone up and you would have made profit. but that doesn't make you an expert. instead it gives you a false sense of being an expert which will be more harmful in the long run when the dumps come (you can see how many people are currently crying about it on bitcointalk and telling everyone how they should have "patience" which is a big mistake).
BUT if you start now, you have to make good decisions otherwise you lose money. so you learn the most important lesson and that is decision making for example in choosing the right entry point and the right exit point.
and if you make the wrong mistake there is no safety net (pump) to cover your ass. which is why you will be forced to learn. and that can help you in the long run.
and know this: even in this dropping market you can still make profit

these days we keep seeing how these throw away accounts here are warning you to sell your bitcoins and how you will lose money,...
you have to wonder why they are so worried about your money and don't want you to lose it so they are telling you to sell your bitcoins LOL.
you gotta ask WHY? what's in it for them if you sell.
i am not saying you should hold. i just want to raise the question that you should have been asking all along about those who create multiple throwaway accounts every day to say the same thing over and over again...

Bithumb was hacked yesterday and the news has been spreading in the major media for at least 14 hours now based on the article times[1]. price however has not shown any reaction to the news and on top of that in the past 14 hours we have had a rise. granted it was a small rise but still it reached $6841 a couple of hours from this news. is this a good sign that we have reached the absolute bottom?[1] https://www.ccn.com/breaking-south-korean-crypto-exchange-bithumb-hacked-thieves-steal-30-million/ |

i keep seeing topics asking "why is it going down" "when will it reach $$$",... and everyone is panicking about when the "moon" is going to be!
well if you are not a trader then why are you even asking these questions? just buy and hold. come back in long term and enjoy the big profit.
if you are a trader then asking these silly questions won't help you. if you see price is not recovering and falling then just adjust your strategy to match the new trend. and i am not just talking about now. this happens each time the trend changes!
market is not always going to stay the same, it has ups and downs and sideways and ... for each of these trends you need a specific strategy. you can't just apply one thing to all of them.

we already know there is a tight relationship between bitcoin price and altcoin prices that whenever bitcoin has a drop altcoins get dumped harder. but what about the opposite? meaning as altcoins bubbles are bursting hard and people want an exit back to fiat they go through bitcoin and that (at the very least) increases the sell pressure on bitcoin and drops the price more. many of the altcoins don't have the fiat markets for people to cash out and also others may even choose bitcoin as a way to exit. i saw this topic which made me think of this: https://bitcointalk.org/index.php?topic=2883297.0 |

(i found this interesting and i didn't see anyone talking about it so here it goes) every year in the past 4 years bitcoin price has a big drop about 3 weeks before Chinese New Yet (Lunar year) and we are at that point in time (4 weeks) and the sell off has started today.  so... what do you think? |
|
|
|
all Chinese exchanges are working fine and even their official announcements are coming out saying there is nothing going on over there in China. here is an example from BTCC (a Chinese exchange and mining pool): BTCChina Exchange is operating normally, and has not received any new directives from Chinese regulators. We'll keep you updated.
now go ahead and continue giving your coins to whales... |

My opposition is not because they are trying to hard fork
not because they are trying to increase the block size to 8 MB and open up many attack vectors.
not because they are effectively centralizing bitcoin.
not because they have the biggest scammer as their speaker.
not because they have been attacking bitcoin and trying to take over for more than 3 years.
...
these are all minor reasons.
the main reason that i am against bitcoinCash is because they are going against the majority. we voted, the nodes, the miners, the businesses, ... and got the majority on the current chain that you see and is called bitcoin.
but you could not accept and did not respect the majority's opinion and still insist on your minority hard fork.
and the worst part is you are going against "satoshi's vision", the very thing you pretend to support. which is a decentralized system that works based on consensus of the majority not what some small group of people want.
and here is a question for you:
you say your proposal is the best, you claim to be the satoshi's vision, and lots more. so why don't you make something from scratch? call it Satoshi's Vistion Coin or SVC for short.

is everyone so excited about the BIP91 activation with 93.1% and the price rising ridiculously fast that they forgot BIP141 (bit 1 version, or you may recall it as original SegWit thingy) is increasing in support? where are the watchers  lets see, here is the list: Antpool
Batpool
BitClub
Bitcoin.com
BitFury
Bixin
BTC.com
BTC.TOP
BTCC
BW pool
F2Pool
GBMiners
Kano CKPool
Slushpool
ViaBTC hope i didn't miss anything. source: https://coin.dance/blocks(i believe this is almost 91% of the total hash power) current percentage: 76.4% so far. also it would be great if someone could give us the time frame of this signaling. is it the same as BIP91 since it is the continuation of that or is it the 1 difficulty period? |

first of all let me clarify that i am talking about Real Cloud Mining not the Ponzi scheme with the name cloud mining on it.
i remember a couple of years ago there have been legitimate cloud mining businesses such as GHASH.io or as you may know it Cex.io and when bitcoin price went down to $200 and stayed around <$400 they paused it (explicitly called it pause) because of higher maintenance fees.
now all the difficulty rise aside, price is nearly $3000 and that covers more than enough of any kind of cost mining has and it is producing a lot of profit for miners.
so my question is, why is there no cloud mining these days? for example why didn't Ghash.io resume their mining again?
