Block chain - Bitcoin Wiki

Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

BCexchange, the decentralized cryptocurrency exchange for everyone

Subreddit for BCexchange (short for ​Blocks & Chains Decentralized Exchange). B&C Exchange will be an open-source decentralized exchange that completes cryptocurrency trades between users by utilizing multisig signers that compete for blockchain rewards based on their effectiveness and honesty. Trades occur using real cryptocurrencies such as Bitcoin and NuBits.


Horizen is an inclusive ecosystem built on its massively scalable blockchain platform where everyone is empowered and rewarded for their contributions. Launched in 2017, our leading-edge platform enables real-life uses outside of our cryptocurrency, ZEN.

Does copyrighted material on the Bitcoin block chain mean that downloading the full block chain is technically illegal?

So, as some of you may know you can actually hide messages in the blockchain. However, this also means that you can hide stuff like a copyrighted book in the blockchain. In fact, someone did just that.
Does this mean that a user downloading the blockchain which happens to contain this book is doing something illegal? How does hiding stuff like this on the blockchain work? Would this constitute copyright infringement? Any info on this would be appreciated. :)

Kelly Kolisnik ‏@kellykolisnik “He who controls the past controls the future. He who controls the present controls the past.” -George Orwell. #Orwell @WikiLeaks
Kelly Kolisnik of Wikileaks tweeted this about an hour after the the earlier version of this post.
Very possible this is a /Wink&Nod/ to indicate we are on the right trail
Blockchain is the key
Backup files found in blockchain. Wikileaks used special insert / withdraw tool.
Characteristics of suspicious transactions:
.0001 BTC to multiple created wallets
Transfers with abnormally high TRANSACTION COSTS, to ensure posting in case of unusually high volume
List of other suspicious transactions - u/Cpt9captain .0001 transfer FEE 291 BTC ($280,000 USD)
The answers are here, it is only a matter of isolating the data. Stay strong. Stay focused. This is history.

He who controls the past controls the future. He who controls the present controls the past. Today He dies.

It will be where the dead switch is released if it exists, and Julian confirms its use in VERIFYING PAST DUMPS. The odd behavior on behalf of Wikileaks Wallet pushed me to do some search into Wikileaks history with Bitcoin. After reading the chan posts about DMS / keyholders / wildcards, I noticed that most documented instances of Julian's discussion of BITCOIN/BLOCKCHAIN architecture always ended up relating to publishing and time verification. (two elements of a DMS). “Bitcoin is an extremely important innovation, but not in the way most people think. Bitcoin’s real innovation is a globally verifiable proof publishing at a certain time. The whole system is built on that concept and many other systems can also be built on it. The block chain nails down history, breaking Orwell’s dictum of ‘He who controls the present controls the past and he who controls the past controls the future’.” IF THERE IS A DMS IT WILL BE ACTIVATED VIA THE BLOCKCHAIN. moreover, IN THIS VIDEO ASSANGE DISCUSSES USING THE BLOCKCHAIN IN THE PAST FOR CRYTO VERIFICATION. We must pour through WIKILEAKS Blockchain transaction history as their is most certainty new/and or undiscovered information/indicators. He knew the dark days would come, and there is no doubt in my mind the answers to the questions we have are answerable due to the breadcrumbs and canary left for us. #FreeJulian

he child porn on the bitcoin block chain was put there purposely

If you haven't heard, child porn was found on the bitcoin blockchain and it was reported by many major news sources:
Many of these news sources say that a report managed to find child porn on the bitcoin blockchain. My theory is that these child porn links and images where put on there by banks and/or governments that really do not like the idea of losing power to something they cannot control

I wish just changed their name. Not a great association to the highly secure bitcoin block chain.

Getting tired of hearing the term thrown around. They should change it to something like BlockWallet or something

The Bitcoin block chain has had fraudulent timestamps before AKA: Unsecure (Assange AMA PsyOP)

See here:
I was watching Julian's AMA the whole time yesterday thinking either (a) He's dead and this is an actor or (b) This is prerecorded.
I am leaning towards the latter.
As well all know is playing ball with the establishment and the top comment from yesterday appeared out of nowhere leapfrogging the most pertinent question and didn't even address the public's concern. Also the first question that was answered was from u/ Beefshake who's comment history reads incredibly biased.
What I am saying is that it is possible Julian was prerecorded answering future NBA matches as if they were yesterday's (I can't imagine he's a big NBA fan so he likely wouldn't notice the fixtures are from the future). Then the scores could be doctored acoustically & visually in post production.
Any questions he "answered" were not read out fully, and could have easily been planted again today appended with seemingly more recent additions (which he did not address).
Furthermore the bitcoin block & hash could have been an illusion also.
It was odd that he made a mistake about the block number. Originally he called out block number 445706 ( a block with a single transaction on the 29/12/2016.
What is coincidental is the transaction from the future linked above turned up just a few days before that. Could SHA 256 have been cracked on the 26th?
SHA 256 was actually developed by the NSA. Obviously they are best placed to understand it's weakness and if anybody were to crack it they'd keep it to themselves but perhaps that transaction from the future is proof of it.
Could the transaction Julian read out have also been "from the future"?
Surely with endless resources and cryptographic knowledge one could mold a transaction hash in the future?
It's possible that the CIA knew Assange likely kept track of the block number so had to actually give him the proper one at the time.
It could be achieved by just giving Assange the real recent block number and false hash, have him corrected to a block number estimated in the future (447506) giving oneself enough time to chain together transactions & amounts & details to ensure the desired false hash can be cemented into the block chain (to a certain amount of characters).
Furthermore since his internet was cut off all the recent events that he discussed (WLTF, Pilger, Anonymous) could have been fabricated at the time (eg. "Hey Julian CNN called you a peadophile" but he would have no way of knowing with no internet).
I also think it was odd that he talked about a non existent police force outside the embassy as if they were still there (since mid-October).
Not to mention the regular muting of the microphone which removes any of Julian's interactions with the controllers (perhaps for example he wasn't allowed choose what sport, or had qualms about the block chain stuff). There was audio clipping surrounding all of that.
In my opinion the AMA was very unconvincing, personally I don't even think the Julian Assange we saw knew Donald Trump had even won the election.

Bitcoin's block chain found to have links to CP sites and image caches

Hey guys, long time lurker, new poster here, love this sub and everything you all do for the community at large. I'm posting this because as someone who is anti-centralized banking, this all seems like an incredibly easy way for centralized banks and the deep state to make sure people can't use Bitcoin anymore. I have dug into this a bit and forgive me if I've missed a few steps here, but basically this is an easy way to outlaw the possession of the block chain for Bitcoin; an essential part of participating in Bitcoin trading. They can't shut down Bitcoin from the inside, and they can't stop people from trading Bitcoin, but they can effectively shut down the legality of the means of trading it. I guess I'm just looking for second opinions here, and if anyone finds anything digging further than this please post! Thanks all, and keep up the questioning!

Bitcoins block chain's size is doubling exponentially!

Chart of Bitcoin blockchain size
Note the year on year doubling exponential growth trend, if you extrapolate that trend you get this...
GB Gigabytes, TB Terabytes, PB Petabytes (steps of 1000x).
Which is not too bad you can buy 16TB hard drives the thing is that the network bandwidth, processing bandwidth and time taken to run the Bitcoin currency will start to grow.
Also it moves from a peer to peer system to a cloud/data centre system as it's processing and storage needs grow.
So Bitcoin the free peer to peer currency will become a monopoly where only a few large data banks can process it's transactions in reasonable time.
Also it is currently estimated to be using 250MW(1), if it doubles every year how long before it needs a large nations power levels and eventually the worlds power needs for itself?
Note China uses about 6PW and the US about 4PW(2)
It has to be the most inefficient banking/currency system ever invented and when you look at what it is supposed to be 'a free digital currency' then forecast what it is becoming a huge inefficient monopoly that looks like it will collapse under it's own weight.
Anyway I thought you might like this long view of the new 'wonder' currency everyone is talking about.

Is a Layer 2 financial industry with the Bitcoin block chain as a backbone really a bad thing?

I've tried to keep communications and amicability open between myself and people like BashCo to show that I'm not just trolling but sharing genuine personal opinions and concerns on the other sub. To this day I've been able to say some pretty aggressive things in favor of what most here believe, without getting banned. That being said, I share the opinions of memorydealers, and most people here, but I wanted to clarify something:
Where do layer two settlement systems fit into all this?
Isn't our real issue here, (given most of us are in the business world versus the coder world), the missed opportunities that we've seen? The industry that could be flourishing right now if we only could support it on the layers above?
If you go back three or four years, you can clearly hear Andreas Antonopoulos aantonop talking on Let's Talk Bitcoin about how bitcoin growth would happen on the layers above. That's always been a "thing".
MasterCoin, Colored Coins, Counterparty, and several other "Bitcoin 2.0 Platform" companies immediately popped up back then to spearhead the entire concept of using Bitcoin in that manner. As a Layer 1 backbone, (or some creative variation of that).
But one by one they either disappeared or never panned out. In the years since, the real frustration for me has been that nobody's doing anything to build a Layer 2 financial industry for Bitcoin. And frequently hearing that those who wanted to, couldn't, because the base layer couldn't support their capacity needs, or feature functionalities.
It's interesting how there's this hybrid mentality here though. If you really think about it - we all agree with that concept, right? As long as the bitcoin block chain is the backbone?
But when were presented with that very rational argument, we sort of pivot, and reply with: "Well bitcoin still needs to scale in order to support that!"
But if that's how we feel, then why don't we stick with that? I dare say we could find some common ground with Core. In fact I dare say we already have common ground with Core. But the real issues we have are getting drown out.
My understanding is that what they are putting together is actually going to be important for extending and supporting Layer 2 industries. This is kind a huge deal (in a good way). Now maybe a Layer 2 system can be more effectively built. So isn't our real concern: "Where the heck was this three years ago?"
Why are we pushing so hard for it to be 100% on the Blockchain?
Isn't the real issue the opportunities we've missed because of the lack of forward progress at a remotely reasonable pace, and the conflict of interest in Core developers being hired by a centralized company that is absolutely affecting the pace, and priority list, for the direction of Bitcoin?
Isn't that really what our desire is? To have the Fidelitys, NASCARs, and Patrick Byrnes able to build their entire systems upon the backbone of the bitcoin block chain?
Is the Layer 2 mentality really a bad thing?
I don't think we all really disagree with layer two settlement services. We just don't want one company literally buying out developers who write code for Bitcoin. They should not be hired by anyone in the block chain space. And if they are hired by a start up in the bitcoin scene, there should be an obvious understanding that said company has no pull on bitcoin code, timelines, or priorities, whatsoever.
