Search for Bitcoin Addresses by Substring?

Say I have a bitcoin address that starts with "15uqx7jmc", but I don't know the rest of it. How do I find a list of bitcoin addresses (using a popular online tool) that have at one point held a balance (or still have a balance) that start with this string? There's probably only one address like this. Thanks in advance!

Search for bitcoin addresses/transactions by amount of bitcoins, such as in a SQL query

I want to find the United States' public bitcoin address as detailed in recent court documents.
This should be possible in a simple SQL-like query since we know the bitcoin amounts of the silkroad addresses seized, and we know the range of the amount of bitcoins to look for, these of which will be statistical outliers in a date range
so does anyone have a publicly accessible way to do this kind of search?

How to search node/blockchain for pub address transactions/totals (offline)? (x-post from /r/Bitcoin)

submitted by ASICmachine to CryptoCurrencyClassic [link] [comments]

Question: Aside from linking through block explorer searches and IP addresses, is it possible for different bitcoin addresses from the same seed to be associated with each other?

For example, say a wallet has an address with a single UTXO which is easily linked to where it was bought on a KYC exchange, and you then send some coinjoined coins from wasabi to a newly generated address in the same wallet, is the privacy of the ‘private’ UTXO immediately compromised? Or is it essentially impossible to tell the two addresses are derived from the same seed? Thank you

Preventing double-spends is an "embarrassingly parallel" massive search problem - like Google, [email protected], [email protected], or PrimeGrid. BUIP024 "address sharding" is similar to Google's MapReduce & Berkeley's BOINC grid computing - "divide-and-conquer" providing unlimited on-chain scaling for Bitcoin.

TL;DR: Like all other successful projects involving "embarrassingly parallel" search problems in massive search spaces, Bitcoin can and should - and inevitably will - move to a distributed computing paradigm based on successful "sharding" architectures such as Google Search (based on Google's MapReduce algorithm), or [email protected], [email protected], or PrimeGrid (based on Berkeley's BOINC grid computing architecture) - which use simple mathematical "decompose" and "recompose" operations to break big problems into tiny pieces, providing virtually unlimited scaling (plus fault tolerance) at the logical / software level, on top of possibly severely limited (and faulty) resources at the physical / hardware level.
The discredited "heavy" (and over-complicated) design philosophy of centralized "legacy" dev teams such as Core / Blockstream (requiring every single node to download, store and verify the massively growing blockchain, and pinning their hopes on non-existent off-chain vaporware such as the so-called "Lightning Network" which has no mathematical definition and is missing crucial components such as decentralized routing) is doomed to failure, and will be out-competed by simpler on-chain "lightweight" distributed approaches such as distributed trustless Merkle trees or BUIP024's "Address Sharding" emerging from independent devs such as u/thezerg1 (involved with Bitcoin Unlimited).
No one in their right mind would expect Google's vast search engine to fit entirely on a Raspberry Pi behind a crappy Internet connection - and no one in their right mind should expect Bitcoin's vast financial network to fit entirely on a Raspberry Pi behind a crappy Internet connection either.
Any "normal" (ie, competent) company with $76 million to spend could provide virtually unlimited on-chain scaling for Bitcoin in a matter of months - simply by working with devs who would just go ahead and apply the existing obvious mature successful tried-and-true "recipes" for solving "embarrassingly parallel" search problems in massive search spaces, based on standard DISTRIBUTED COMPUTING approaches like Google Search (based on Google's MapReduce algorithm), or [email protected], [email protected], or PrimeGrid (based on Berkeley's BOINC grid computing architecture). The fact that Blockstream / Core devs refuse to consider any standard DISTRIBUTED COMPUTING approaches just proves that they're "embarrassingly stupid" - and the only way Bitcoin will succeed is by routing around their damage.
Proven, mature sharding architectures like the ones powering Google Search, [email protected], [email protected], or PrimeGrid will allow Bitcoin to achieve virtually unlimited on-chain scaling, with minimal disruption to the existing Bitcoin network topology and mining and wallet software.
Longer Summary:
People who argue that "Bitcoin can't scale" - because it involves major physical / hardware requirements (lots of processing power, upload bandwidth, storage space) - are at best simply misinformed or incompetent - or at worst outright lying to you.
Bitcoin mainly involves searching the blockchain to prevent double-spends - and so it is similar to many other projects involving "embarrassingly parallel" searching in massive search spaces - like Google Search, [email protected], [email protected], or PrimeGrid.
But there's a big difference between those long-running wildly successful massively distributed infinitely scalable parallel computing projects, and Bitcoin.
Those other projects do their data storage and processing across a distributed network. But Bitcoin (under the misguided "leadership" of Core / Blockstream devs) instists on a fatally flawed design philosophy where every individual node must be able to download, store and verify the system's entire data structure. And it's even wore than that - they want to let the least powerful nodes in the system dictate the resource requirements for everyone else.
Meanwhile, those other projects are all based on some kind of "distributed computing" involving "sharding". They achieve massive scaling by adding a virtually unlimited (and fault-tolerant) logical / software layer on top of the underlying resource-constrained / limited physical / hardware layer - using approaches like Google's MapReduce algorithm or Berkeley's Open Infrastructure for Network Computing (BOINC) grid computing architecture.
This shows that it is a fundamental error to continue insisting on viewing an individual Bitcoin "node" as the fundamental "unit" of the Bitcoin network. Coordinated distributed pools already exist for mining the blockchain - and eventually coordinated distributed trustless architectures will also exist for verifying and querying it. Any architecture or design philosophy where a single "node" is expected to be forever responsible for storing or verifying the entire blockchain is the wrong approach, and is doomed to failure.
The most well-known example of this doomed approach is Blockstream / Core's "roadmap" - which is based on two disastrously erroneous design requirements:
  • Core / Blockstream erroneously insist that the entire blockchain must always be downloadable, storable and verifiable on a single node, as dictated by the least powerful nodes in the system (eg, u/bitusher in Costa Rica), or u/Luke-Jr in the underserved backwoods of Florida); and
  • Core / Blockstream support convoluted, incomplete off-chain scaling approaches such as the so-called "Lightning Network" - which lacks a mathematical foundation, and also has some serious gaps (eg, no solution for decentralized routing).
Instead, the future of Bitcoin will inevitably be based on unlimited on-chain scaling, where all of Bitcoin's existing algorithms and data structures and networking are essentially preserved unchanged / as-is - but they are distributed at the logical / software level using sharding approaches such as u/thezerg1's BUIP024 or distributed trustless Merkle trees.
These kinds of sharding architectures will allow individual nodes to use a minimum of physical resources to access a maximum of logical storage and processing resources across a distributed network with virtually unlimited on-chain scaling - where every node will be able to use and verify the entire blockchain without having to download and store the whole thing - just like Google Search, [email protected], [email protected], or PrimeGrid and other successful distributed sharding-based projects have already been successfully doing for years.
Details:
Sharding, which has been so successful in many other areas, is a topic that keeps resurfacing in various shapes and forms among independent Bitcoin developers.
The highly successful track record of sharding architectures on other projects involving "embarrassingly parallel" massive search problems (harnessing resource-constrained machines at the physical level into a distributed network at the logical level, in order to provide fault tolerance and virtually unlimited scaling searching for web pages, interstellar radio signals, protein sequences, or prime numbers in massive search spaces up to hundreds of terabytes in size) provides convincing evidence that sharding architectures will also work for Bitcoin (which also requires virtually unlimited on-chain scaling, searching the ever-expanding blockchain for previous "spends" from an existing address, before appending a new transaction from this address to the blockchain).
Below are some links involving proposals for sharding Bitcoin, plus more discussion and related examples.

Some kind of sharding - perhaps based on address sharding as in BUIP024, or based on distributed trustless Merkle trees as proposed earlier by u/thezerg1 - is very likely to turn out to be the simplest, and safest approach towards massive on-chain scaling.
A thought experiment showing that we already have most of the ingredients for a kind of simplistic "instant sharding"
A simplistic thought experiment can be used to illustrate how easy it could be to do sharding - with almost no changes to the existing Bitcoin system.
Recall that Bitcoin addresses and keys are composed from an alphabet of 58 characters. So, in this simplified thought experiment, we will outline a way to add a kind of "instant sharding" within the existing system - by using the last character of each address in order to assign that address to one of 58 shards.
(Maybe you can already see where this is going...)
Similar to vanity address generation, a user who wants to receive Bitcoins would be required to generate 58 different receiving addresses (each ending with a different character) - and, similarly, miners could be required to pick one of the 58 shards to mine on.
Then, when a user wanted to send money, they would have to look at the last character of their "send from" address - and also select a "send to" address ending in the same character - and presto! we already have a kind of simplistic "instant sharding". (And note that this part of the thought experiment would require only the "softest" kind of soft fork: indeed, we haven't changed any of the code at all, but instead we simply adopted a new convention by agreement, while using the existing code.)
Of course, this simplistic "instant sharding" example would still need a few more features in order to be complete - but they'd all be fairly straightforward to provide:
  • A transaction can actually send from multiple addresses, to multiple addresses - so the approach of simply looking at the final character of a single (receive) address would not be enough to instantly assign a transaction to a particular shard. But a slightly more sophisticated decision criterion could easily be developed - and computed using code - to assign every transaction to a particular shard, based on the "from" and "to" addresses in the transaction. The basic concept from the "simplistic" example would remain the same, sharding the network based on some characteristic of transactions.
  • If we had 58 shards, then the mining reward would have to be decreased to 1/58 of what it currently is - and also the mining hash power on each of the shards would end up being roughly 1/58 of what it is now. In general, many people might agree that decreased mining rewards would actually be a good thing (spreading out mining rewards among more people, instead of the current problems where mining is done by about 8 entities). Also, network hashing power has been growing insanely for years, so we probably have way more than enough needed to secure the network - after all, Bitcoin was secure back when network hash power was 1/58 of what it is now.
  • This simplistic example does not handle cases where you need to do "cross-shard" transactions. But it should be feasible to implement such a thing. The various proposals from u/thezerg1 such as BUIP024 do deal with "cross-shard" transactions.
(Also, the fact that a simplified address-based sharding mechanics can be outlined in just a few paragraphs as shown here suggests that this might be "simple and understandable enough to actually work" - unlike something such as the so-called "Lightning Network", which is actually just a catchy-sounding name with no clearly defined mechanics or mathematics behind it.)
Addresses are plentiful, and can be generated locally, and you can generate addresses satisfying a certain pattern (eg ending in a certain character) the same way people can already generate vanity addresses. So imposing a "convention" where the "send" and "receive" address would have to end in the same character (and where the miner has to only mine transactions in that shard) - would be easy to understand and do.
Similarly, the earlier solution proposed by u/thezerg1, involving distributed trustless Merkle trees, is easy to understand: you'd just be distributing the Merkle tree across multiple nodes, while still preserving its immutablity guarantees.
Such approaches don't really change much about the actual system itself. They preserve the existing system, and just split its data structures into multiple pieces, distributed across the network. As long as we have the appropriate operators for decomposing and recomposing the pieces, then everything should work the same - but more efficiently, with unlimited on-chain scaling, and much lower resource requirements.
The examples below show how these kinds of "sharding" approaches have already been implemented successfully in many other systems.
Massive search is already efficiently performed with virtually unlimited scaling using divide-and-conquer / decompose-and-recompose approaches such as MapReduce and BOINC.
Every time you do a Google search, you're using Google's MapReduce algorithm to solve an embarrassingly parallel problem.
And distributed computing grids using the Berkeley Open Infrastructure for Network Computing (BOINC) are constantly setting new records searching for protein combinations, prime numbers, or radio signals from possible intelligent life in the universe.
We all use Google to search hundreds of terabytes of data on the web and get results in a fraction of a second - using cheap "commodity boxes" on the server side, and possibly using limited bandwidth on the client side - with fault tolerance to handle crashing servers and dropped connections.
Other examples are [email protected], [email protected] and PrimeGrid - involving searching massive search spaces for protein sequences, interstellar radio signals, or prime numbers hundreds of thousands of digits long. Each of these examples uses sharding to decompose a giant search space into smaller sub-spaces which are searched separately in parallel and then the resulting (sub-)solutions are recomposed to provide the overall search results.
It seems obvious to apply this tactic to Bitcoin - searching the blockchain for existing transactions involving a "send" from an address, before appending a new "send" transaction from that address to the blockchain.
Some people might object that those systems are different from Bitcoin.
But we should remember that preventing double-spends (the main thing that the Bitcoin does) is, after all, an embarrassingly parallel massive search problem - and all of these other systems also involve embarrassingly parallel massive search problems.
The mathematics of Google's MapReduce and Berkeley's BOINC is simple, elegant, powerful - and provably correct.
Google's MapReduce and Berkeley's BOINC have demonstrated that in order to provide massive scaling for efficient searching of massive search spaces, all you need is...
  • an appropriate "decompose" operation,
  • an appropriate "recompose" operation,
  • the necessary coordination mechanisms
...in order to distribute a single problem across multiple, cheap, fault-tolerant processors.
This allows you to decompose the problem into tiny sub-problems, solving each sub-problem to provide a sub-solution, and then recompose the sub-solutions into the overall solution - gaining virtually unlimited scaling and massive efficiency.
The only "hard" part involves analyzing the search space in order to select the appropriate DECOMPOSE and RECOMPOSE operations which guarantee that recomposing the "sub-solutions" obtained by decomposing the original problem is equivalent to the solving the original problem. This essential property could be expressed in "pseudo-code" as follows:
  • (DECOMPOSE ; SUB-SOLVE ; RECOMPOSE) = (SOLVE)
Selecting the appropriate DECOMPOSE and RECOMPOSE operations (and implementing the inter-machine communication coordination) can be somewhat challenging, but it's certainly doable.
In fact, as mentioned already, these things have already been done in many distributed computing systems. So there's hardly any "original work to be done in this case. All we need to focus on now is translating the existing single-processor architecture of Bitcoin to a distributed architecture, adopting the mature, proven, efficient "recipes" provided by the many examples of successful distributed systems already up and running like such as Google Search (based on Google's MapReduce algorithm), or [email protected], [email protected], or PrimeGrid (based on Berkeley's BOINC grid computing architecture).
That's what any "competent" company with $76 million to spend would have done already - simply work with some devs who know how to implement open-source distributed systems, and focus on adapting Bitcoin's particular data structures (merkle trees, hashed chains) to a distributed environment. That's a realistic roadmap that any team of decent programmers with distributed computing experience could easily implement in a few months, and any decent managers could easily manage and roll out on a pre-determined schedule - instead of all these broken promises and missed deadlines and non-existent vaporware and pathetic excuses we've been getting from the incompetent losers and frauds involved with Core / Blockstream.
ASIDE: MapReduce and BOINC are based on math - but the so-called "Lightning Network" is based on wishful thinking involving kludges on top of workarounds on top of hacks - which is how you can tell that LN will never work.
Once you have succeeded in selecting the appropriate mathematical DECOMPOSE and RECOMPOSE operations, you get simple massive scaling - and it's also simple for anyone to verify that these operations are correct - often in about a half-page of math and code.
An example of this kind of elegance and brevity (and provable correctness) involving compositionality can be seen in this YouTube clip by the accomplished mathematician Lucius Greg Meredith presenting some operators for scaling Ethereum - in just a half page of code:
https://youtu.be/uzahKc_ukfM?t=1101
Conversely, if you fail to select the appropriate mathematical DECOMPOSE and RECOMPOSE operations, then you end up with a convoluted mess of wishful thinking - like the "whitepaper" for the so-called "Lightning Network", which is just a cool-sounding name with no actual mathematics behind it.
The LN "whitepaper" is an amateurish, non-mathematical meandering mishmash of 60 pages of "Alice sends Bob" examples involving hacks on top of workarounds on top of kludges - also containing a fatal flaw (a lack of any proposed solution for doing decentralized routing).
The disaster of the so-called "Lightning Network" - involving adding never-ending kludges on top of hacks on top of workarounds (plus all kinds of "timing" dependencies) - is reminiscent of the "epicycles" which were desperately added in a last-ditch attempt to make Ptolemy's "geocentric" system work - based on the incorrect assumption that the Sun revolved around the Earth.
This is how you can tell that the approach of the so-called "Lightning Network" is simply wrong, and it would never work - because it fails to provide appropriate (and simple, and provably correct) mathematical DECOMPOSE and RECOMPOSE operations in less than a single page of math and code.
Meanwhile, sharding approaches based on a DECOMPOSE and RECOMPOSE operation are simple and elegant - and "functional" (ie, they don't involve "procedural" timing dependencies like keeping your node running all the time, or closing out your channel before a certain deadline).
Bitcoin only has 6,000 nodes - but the leading sharding-based projects have over 100,000 nodes, with no financial incentives.
Many of these sharding-based projects have many more nodes than the Bitcoin network.
The Bitcoin network currently has about 6,000 nodes - even though there are financial incentives for running a node (ie, verifying your own Bitcoin balance.
[email protected] and [email protected] each have over 100,000 active users - even though these projects don't provide any financial incentives. This higher number of users might be due in part the the low resource demands required in these BOINC-based projects, which all are based on sharding the data set.
[email protected]
As part of the client-server network architecture, the volunteered machines each receive pieces of a simulation (work units), complete them, and return them to the project's database servers, where the units are compiled into an overall simulation.
In 2007, Guinness World Records recognized [email protected] as the most powerful distributed computing network. As of September 30, 2014, the project has 107,708 active CPU cores and 63,977 active GPUs for a total of 40.190 x86 petaFLOPS (19.282 native petaFLOPS). At the same time, the combined efforts of all distributed computing projects under BOINC totals 7.924 petaFLOPS.
[email protected]
Using distributed computing, [email protected] sends the millions of chunks of data to be analyzed off-site by home computers, and then have those computers report the results. Thus what appears an onerous problem in data analysis is reduced to a reasonable one by aid from a large, Internet-based community of borrowed computer resources.
Observational data are recorded on 2-terabyte SATA hard disk drives at the Arecibo Observatory in Puerto Rico, each holding about 2.5 days of observations, which are then sent to Berkeley. Arecibo does not have a broadband Internet connection, so data must go by postal mail to Berkeley. Once there, it is divided in both time and frequency domains work units of 107 seconds of data, or approximately 0.35 megabytes (350 kilobytes or 350,000 bytes), which overlap in time but not in frequency. These work units are then sent from the [email protected] server over the Internet to personal computers around the world to analyze.
Data is merged into a database using [email protected] computers in Berkeley.
The [email protected] distributed computing software runs either as a screensaver or continuously while a user works, making use of processor time that would otherwise be unused.
Active users: 121,780 (January 2015)
PrimeGrid
PrimeGrid is a distributed computing project for searching for prime numbers of world-record size. It makes use of the Berkeley Open Infrastructure for Network Computing (BOINC) platform.
Active users 8,382 (March 2016)
MapReduce
A MapReduce program is composed of a Map() procedure (method) that performs filtering and sorting (such as sorting students by first name into queues, one queue for each name) and a Reduce() method that performs a summary operation (such as counting the number of students in each queue, yielding name frequencies).
How can we go about developing sharding approaches for Bitcoin?
We have to identify a part of the problem which is in some sense "invariant" or "unchanged" under the operations of DECOMPOSE and RECOMPOSE - and we also have to develop a coordination mechanism which orchestrates the DECOMPOSE and RECOMPOSE operations among the machines.
The simplistic thought experiment above outlined an "instant sharding" approach where we would agree upon a convention where the "send" and "receive" address would have to end in the same character - instantly providing a starting point illustrating some of the mechanics of an actual sharding solution.
BUIP024 involves address sharding and deals with the additional features needed for a complete solution - such as cross-shard transactions.
And distributed trustless Merkle trees would involve storing Merkle trees across a distributed network - which would provide the same guarantees of immutability, while drastically reducing storage requirements.
So how can we apply ideas like MapReduce and BOINC to providing massive on-chain scaling for Bitcoin?
First we have to examine the structure of the problem that we're trying to solve - and we have to try to identify how the problem involves a massive search space which can be decomposed and recomposed.
In the case of Bitcoin, the problem involves:
  • sequentializing (serializing) APPEND operations to a blockchain data structure
  • in such a way as to avoid double-spends
Can we view "preventing Bitcoin double-spends" as a "massive search space problem"?
Yes we can!
Just like Google efficiently searches hundreds of terabytes of web pages for a particular phrase (and [email protected], [email protected], PrimeGrid etc. efficiently search massive search spaces for other patterns), in the case of "preventing Bitcoin double-spends", all we're actually doing is searching a massive seach space (the blockchain) in order to detect a previous "spend" of the same coin(s).
So, let's imagine how a possible future sharding-based architecture of Bitcoin might look.
We can observe that, in all cases of successful sharding solutions involving searching massive search spaces, the entire data structure is never stored / searched on a single machine.
Instead, the DECOMPOSE and RECOMPOSE operations (and the coordination mechanism) a "virtual" layer or grid across multiple machines - allowing the data structure to be distributed across all of them, and allowing users to search across all of them.
This suggests that requiring everyone to store 80 Gigabytes (and growing) of blockchain on their own individual machine should no longer be a long-term design goal for Bitcoin.
Instead, in a sharding environment, the DECOMPOSE and RECOMPOSE operations (and the coordination mechanism) should allow everyone to only store a portion of the blockchain on their machine - while also allowing anyone to search the entire blockchain across everyone's machines.
This might involve something like BUIP024's "address sharding" - or it could involve something like distributed trustless Merkle trees.
In either case, it's easy to see that the basic data structures of the system would remain conceptually unaltered - but in the sharding approaches, these structures would be logically distributed across multiple physical devices, in order to provide virtually unlimited scaling while dramatically reducing resource requirements.
This would be the most "conservative" approach to scaling Bitcoin: leaving the data structures of the system conceptually the same - and just spreading them out more, by adding the appropriately defined mathematical DECOMPOSE and RECOMPOSE operators (used in successful sharding approaches), which can be easily proven to preserve the same properties as the original system.
Conclusion
Bitcoin isn't the only project in the world which is permissionless and distributed.
Other projects (BOINC-based permisionless decentralized [email protected], [email protected], and PrimeGrid - as well as Google's (permissioned centralized) MapReduce-based search engine) have already achieved unlimited scaling by providing simple mathematical DECOMPOSE and RECOMPOSE operations (and coordination mechanisms) to break big problems into smaller pieces - without changing the properties of the problems or solutions. This provides massive scaling while dramatically reducing resource requirements - with several projects attracting over 100,000 nodes, much more than Bitcoin's mere 6,000 nodes - without even offering any of Bitcoin's financial incentives.
Although certain "legacy" Bitcoin development teams such as Blockstream / Core have been neglecting sharding-based scaling approaches to massive on-chain scaling (perhaps because their business models are based on misguided off-chain scaling approaches involving radical changes to Bitcoin's current successful network architecture, or even perhaps because their owners such as AXA and PwC don't want a counterparty-free new asset class to succeed and destroy their debt-based fiat wealth), emerging proposals from independent developers suggest that on-chain scaling for Bitcoin will be based on proven sharding architectures such as MapReduce and BOINC - and so we should pay more attention to these innovative, independent developers who are pursuing this important and promising line of research into providing sharding solutions for virtually unlimited on-chain Bitcoin scaling.

The project aim: Search for the private keys to the lost Bitcoin addresses.

Offer of the participation in a highly profitable project. (PreICO, ICO). It is valid until March 9, 2018.
The project aim: Search for the private keys to the lost Bitcoin addresses.
In short: The Bitcoin network has addresses, which have a large number of Bitcoins. But these addresses have not worked for a long time, since the owners of those addresses have lost their private key to them. The Bitcoin network is owned by the owner, who has the private key from the address.
That is, we become the owners of this address by selecting a private key and we can control the Bitcoins, which are there.
Example: The address, on which 8000 Bitcoins are located since 2009. But there are addresses, on which there are about 60 000 Bitcoins. bitcoins.https://blockchain.info/address/198aMn6ZYAczwrE5NvNTUMyJ5qkfy4g3Hi
The terms and conditions of the collecting funds are at the end of the text.
If the private key to the address is found
The first participants of this project (after finding a private key to an address that we tell only to investors) are guaranteed:
Any Investors, who have invested from 1 Bitcoin and more at the initial stage, are guaranteed a reward, for 1 invested Bitcoin the payment is 150 Bitcoins. 1: 150
The Investors, who will copy this offer and place it in their social networks with a link to this topic in the forum, are guaranteed a reward, for 1 invested Bitcoin the payment is 1: 130 (You just need to write me on mail with a link to your page, where the post is. Your post should be visible before March 9, 2018. My address is [email protected])
The percentage distribution of Bitcoins after finding of the private key to the address:
40% are distributed among the Investors 30% are distributed among the development team 10% are distributed for the further development of the project 20% are distributed for the charitable activities, namely: the installation and operation of computer classes in Russian orphanages.
Other Income, which will also be distributed among the Investors and go for the development of the project:
These revenues will be divided and paid out every three months, at a ratio of: 30% to the initial investors 30% to the team. 30% to the work and project development. 10% to the charity.
The terms and conditions for collecting funds from 3 to 100 Bitcoins until March 9, 2018:
The initial attraction of investors, with great demand, will close at a sum of 100 BTC. The subsequent receipts will be returned to the addresses, from which they arrived (minus the net commission).
The terms and conditions of investment privacy: - Return of investments and profits will be made to the address, from which they entered. - If the Investor wants to protect himself (from losing the private key of the investment address) or to obtain secret information about the address, to which the private key is selected, he must write an e-mail before payment, specifying the investment sum and the address of the Bitcoin, where the payment will come from.

Somebody might say that I'm a fraud. But I have the answer for them: Do you have a Facebook profile for more than 5-7 years? Is it open for everybody? Do you have a phone number, e-mail in the public domain? Is it open for everybody? Do you have a professional questionnaire on LinkedIn? Is it open for everybody? Do you show data on the network? Do you know that it is badly to write anonymously and with impunity without knowing a person?

  4. If none found, click on the Previous Block and repeat
  5. When you find a coincidence, make sure it's the destination address and it ends with "cVDsb4Ysvr".
We know the first 9 and the last 10 characters of the address. This is a total of 19*log(58)/log(2) = 111.3 bits. If we discount the 1st leading byte for network version, and the last 4 bytes [used for checksum]1 , we are left with 71.3 bits of the address itself. So there is less than 1 in 271.3 chance of a false positive.
But really, the checksum is based on the whole address, so we can really count it against false positives, lowering that to just a 1 in 2103.3 chance.
If we add the fact that we know the exact value of the transaction, and we can suspect that it's a recent one, there is a really high chance that that's the one.

How to safely store and remember easily your bitcoin public and private keys

Bitcoin addresses (public and private keys) are long and hard to remember. Even vanity addresses only have the first few characters have meaning.
Storing the keys electronically (like email / txt file, etc.) however exposes you to being hacked and all your coins being stolen.
Easiest thing i've found is to create a simple encryption for your private keys before storing them in electronic format.
Also, try to generate the bitcoin addresses offline (try searching for 'bitcoin address utility') and by yourself. I find that by starting with the HEX private key (which is just 64 character string using A-F and 0-9) you could essentially make up a word that is easy to remember and has meaning to you:
If you like this way of keeping your bitcoin safe and easily storing and remembering your keys then feel free to tip me at 1733rLsmW4E6bpFF3GSRRvzfsjq4ixL14d :)

Accessing the UTXO set, searching for address prefixes /Bitcoin submitted by BitcoinAllBot to BitcoinAll [link] [comments]

FYI: yesterday I got trolled by someone using a password from a hacked account, and fishing for a payout. The password was a simple one I used on a few old accounts. It was really a blessing, because it finally motivated me to set up 1Password, and start migrating my 400+ accts/logins to it.

In case any user has a related question, you'll know why... The subject of the email was my old password. Here's the body:
I know [xxxx] is one of your password on day of hack.
Lets get directly to the point.
Not one person has paid me to check about you.
You do not know me and you're probably thinking why you are getting this email?
in fact, i actually placed a malware on the adult vids (adult porn) website and you know what, you visited this site to experience fun (you know what i mean).
When you were viewing videos, your browser started out operating as a RDP having a key logger which provided me with accessibility to your display and web cam.
immediately after that, my malware obtained every one of your contacts from your Messenger, FB, as well as email account.
after that i created a double-screen video. 1st part shows the video you were viewing (you have a nice taste omg), and 2nd part displays the recording of your cam, and its you.
Best solution would be to pay me $1007.
We are going to refer to it as a donation. in this situation, i most certainly will without delay remove your video.
My -BTC -address: [wishful thinking]
[case SeNSiTiVe, copy & paste it]
You could go on your life like this never happened and you will not ever hear back again from me.
You'll make the payment via Bitcoin (if you do not know this, search 'how to buy bitcoin' in Google).
if you are planning on going to the law, surely, this e-mail can not be traced back to me, because it's hacked too.
I have taken care of my actions. i am not looking to ask you for a lot, i simply want to be paid.
if i do not receive the bitcoin;, i definitely will send out your video recording to all of your contacts including friends and family, co-workers, and so on.
Nevertheless, if i do get paid, i will destroy the recording immediately.
If you need proof, reply with Yeah then i will send out your video recording to your 8 friends.
it's a nonnegotiable offer and thus please don't waste mine time & yours by replying to this message.

[ilpt] my indepth guide to ewhoring (250+ a day)

New to this forum so id like to share some of my experience with one of the things that made me a lot, ewhoring.
1) first of your going to want to create a snapchat account, this account must have a high enough snapscore of a couple of thousand to make it look legit as possible, you can boost the snapscore of the account by sending tons of snaps to a bunch of celebrity accounts on snapchat. You can easily find these buy just searching any letter in the search bar and subscribing to all the accounts. add a bitmoji that looks like your girl, you can find a ton of mega links on the internet if you look, try find something not saturated and you should be fine. A good way to look legit on snapchat is of course to send live snaps. To send live snaps uploaded through your camera roll. On iPhone you can use the app prequel. on android you can use chicken cam. Other ways to look legit is to fake your location of the person you’re talking to. My way of doing this was jailbreaking my phone and using snapbreak. you can find tutorials on how to jailbreak everywhere and downloading snapbreak you’ll have to downgrade snapchat first. keep in mind recently snapchat has been banning accounts that have downgraded there snapchat so a way to get around this is to create the account on the downgraded version of snapchat and NEVER update. if you update you won’t be able to use snapbreak without a ban. snapbreak is an amazing tool for all sorts of stuff. Uploading to live snap. faking location. quick switching between accounts, sending snaps to everyone on your snapchat (more than 200 people)
2) one of the first ways i used to get traffic to my account was POF. POF you can create an account with a phone number, with your girl’s pics of course. (do not put add my snap in the bio or you’ll be flagged on the system), just swipe right on everyone and ask everyone to add your snap, "hey add my snap ____ ", people who won’t add you will not buy shit so don’t waste your time. if you do get banned on POF you can use the same phone number a few more times till your perma banned. it’s all about high quality traffic. If you get shit traffic you’ll have a bunch of time wasters on your snap that’s never going to buy. Refrain from doing sfs with other snap chatters unless you want shit traffic. Tinder is also a good source for high quality traffic. all tough once your banned on iPhone you will be mac banned. Changing your ip won’t work and even on a jailbroken iPhone you can’t change your mac. On android devices you can change your mac with rooted devices. I personally wouldn’t go through the effort and I would just make tinder accounts through pc. You can download tmac v6, and any proxy VPN will work. Always remember to clear cookies before creating a new account. Eventually you will run out of phone numbers to use once you get banned but we will get into that in the next step.
​​​​​​​3) Smspva.com and smspool are great tools to get disposable phone numbers to create new accounts. For a small payment of like 50c to $1 per phone number. This can be paid through bitcoin. Hopefully you’ve made enough money at this stage through the traffic you got from your own number. (Yes using your own number is fine if you don’t care about getting banned from TindePOF) anyways. We will talk about how to get your ewhoring money into bitcoin in the next step.
4) Once your money is in bitcoin you can do whatever you want with it, in PayPal if you keep the money in your account to long it can be risked getting locked since you’ll be creating a PayPal account with your girls name/email. PayPal will constantly ask you to verify your account by adding a credit card or sometimes locking your account until you send proof of id. You can only get a maximum of 2500 per unverified PayPal account before they ask for verification (proof of id) you can create new PayPal accounts with new phone numbers through smspva/smspool. Paxful is a great tool to transfer your PayPal money to bitcoin. all tough ive heard you can trade PayPal to bitcoin on multiple other sites. Paxful was the one to work best for me. As I wouldn’t recommend keeping money in your PayPal account to long I suggest getting it into bitcoin asap. After a while paxful will ask for verification on your account. At this point you can just create a new account with a new email/phone number using smspool. I don’t think smspva has paxful verification phone numbers. Personally I traded about 300 at a time on paxful. And id be very wary of scammers. Once the bitcoin is in your paxful wallet. Transfer it to a third party wallet like Blockchain.
5) Let’s get back to the snapchat, remember it’s all about social engineering, get rid of the time wasters, all you want to do is create a private story to post a bunch of nude videos in and put on your main story and try advertise to everyone that your selling a premium snapchat, my prices were 20 monthly 30 lifetime to be a premium member. I charged 40 an hour for video calls. Yes I just blocked them after I received the payment. I charged 150 an hour 400 a night for meetups. With meetup scams I would ask them to pay a 75 deposit through PayPal and id send them the address, they can pay rest cash in hand or in PayPal. Once they would arrive at the address I’ve sent, (this would be a random for sale or address where no one lives in) I would tell them to pay the rest in PayPal and I’ll let them into the house. Even if they said they’d pay the rest in cash id still try tricking them into sending the rest of the payment in PayPal. I’ve made 750 of one guy using this method.
Tips:

any feed back on this method would be greatly appreciated, tell me what you think :)
