Cross-platform desktop application that allows users to trade national currency (dollars, euros, etc) for bitcoin without relying on centralized exchanges New development has moved to bisq-git, but bisq-git may not be currently building. In that case, please try bisq or bisq-bin. I added jdk8-openjdk as a make dependency. Maybe that will help with the building. I'm not sure if jdk8-openjdk is needed to run. "Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.2:compile (default-compile) on project bitcoinj-examples: Fatal error compiling: invalid target release: 1.8 -> [Help 1]" I'm not exactly sure how to to install this package either. It looks like bitcoinj should be a separate package which is a dependency of this package. bitcoinj doesn't exist as a package though. honestly i dont know a thing about maven, i just read bitsquare build doc and blindly applying to pkgbuild. if someone know how to do it right, i'll be happy archer :) I don't think we should use `mvn install` during the build step. Installing should only take place after the package step. Isn't that right? bello buddy, this is work for me I've updated the dependency for openjfx. Right now the build is broken, I think due to upstream. My build couldn't find the bitcoinj dependency. stevenroose commented on 2016-02-01 15:43 It does not take this package as a fulfillment of the openjfx dependency.

How To Get Copy Of Bitcoin Source Code

How To Get Copy Of Bitcoin Source Code

bitcoind is what is most widely used. And here is the source: But there's various other implementations for clients such as BitcoinJ for Java or for C++. However, for miners the story is a bit different. If you're a miner you kind of need to use bitcoind. Otherwise bad things might happen such as the blockchain fork from last March: Continue reading >>

Bitcoinj Namecoin Name Lookup Client

Bitcoinj Namecoin Name Lookup Client

This is documentation for the BitcoinJ-based name lookup client by Namecoins Lead Application Engineer Jeremy Rand. It is based on the following pre-existing projects: Warning: this is beta software, and is not suitable for production use. It is being made available for testing purposes only. It doesnt support proxying or stream isolation. In the examples on this page, we explicitly pass command-line arguments telling the client that this is okay. Leaving off those arguments will result in an error for safety reasons. (This is only if you want to build from source.) Install OpenJDK from your package repositories. These instructions will be updated later with specific package names. Development was done with JDK 8; JDK 7 might work but is untested. Make sure that the JAVA_HOME environment variable is set. On Jeremys Debian Jessie VM, he had to manually set it to /usr/lib/jvm/java-8-openjdk-amd64. Install Maven from your package repositories. These instructions will be updated later with specific package names. Install JDK. Note that Oracles download site doesnt support TLS. If you enjoy being MITM-attacked and installing malware, you can download it here (non-TLS link) . Make sure that the JAVA_HOME environment variable is set. On Jeremys Windows 10 VM, he had to manually set it to C:\Program Files\Java\jdk1.8.0_101. Install Maven. Note that Mavens official download site uses non-TLS downloads (insecure), MD5 checksums (insecure), and 1024-bit DSA signing keys (insecure). If you enjoy being MITM-attacked and installing malware, you can use the Maven download page and the Maven install page . For those of you who dont enjoy installing malware, we suggest building from source on GNU/Linux and copying the binary to Windows. No idea.

How Can I Hardcode A Private Key In Bitcoinj - Eckey Constructor?

How Can I Hardcode A Private Key In Bitcoinj - Eckey Constructor?

how can I hardcode a private key in bitcoinJ - ECKey constructor? Can someone please explain how to use the following constructor (listed here ): ECKey(BigInteger priv, org.spongycastle.math.ec.ECPoint pub) How do I get the big integer representation of it (in other words, and if I understood correctly, is there a function to go from check58 to biginteger?) , and If all you are after is getting an ECKey object for that private key, then Bitcoinj has a DumpedPrivateKey class for just such an occasion. import org.bitcoinj.core.ECKey;import org.bitcoinj.core.DumpedPrivateKey;import org.bitcoinj.params.MainNetParams;public class Example { public static void main(String[] args) { String priv = "L4...5"; ECKey key = DumpedPrivateKey.fromBase58(MainNetParams.get(), priv).getKey(); }} If you would like to use an ECKey constructor explicitly, then you should be able to get the code you need from here: With respect to the constructor you listed, it is a protected constructor, so it's probably not one you would be looking to use. It lists a private key and public key parameters. The private key may be null if the ECKey instance is only going to be used for verifying signatures, not actually producing them. The public key must not be null, and it saves time by not needing to re-compute the public key, which is a CPU intensive operation. Note that most of the public ECKey constructors are deprecated. The preferred way of creating the ECKey objects now is to use the static factory methods. Continue reading >>

What is bitcoinj? Some projects using bitcoinj bitcoinj is a library for working with the Bitcoin protocol. It can maintain a wallet, send/receive transactions without needing a local copy of Bitcoin Core and has many other advanced features. It's implemented in Java but can be used from any JVM compatible language: examples in Python and JavaScript are included. It comes with full documentation and many large, well known Bitcoin apps and services are built on it.

  • Highly optimised lightweight simplified payment verification (SPV) mode. In this mode, only a small part of the block chain is downloaded, making bitcoinj suitable for usage on constrained devices like smartphones or cheap virtual private servers.
  • Experimental full verification mode, which does the same verification work as Bitcoin Core. In this mode, the unspent transaction output set (UTXO set) is calculated and, thanks to a PostgreSQL store, can be indexed into a database allowing for fast lookup of balance by address.
  • A wallet class with encryption, fee calculation, multi-signing, deterministic key derivation, pluggable coin selection/coin control, extensions support and event listeners that let you stay up to date with changes in your balance.
  • Support for micropayment channels that let you set up a multi-signature contract between client and server, and then negotiate on the channel, allowing fast micropayments that avoid miner fees.
  • Provides both async and thread-per-connection for network IO, allowing you to choose between scalability and blocking-only features like SOCKS/Tor proxying.
  • Easily implement apps that use Bitcoin's contracts features.
  • A simple GUI wallet app that you can use as the basis for your own apps. Watch or read a tutorial on Continue reading >>

  • Bitcoin Programming With Bitcoinj

    Bitcoin Programming With Bitcoinj

    In Appendix A, we dabbled with JavaScript code that could perform some basic actions with a Bitcoin wallet by automating a preexisting wallet. In this appendix, we'll write far more powerful programs that directly insert themselves into the Bitcoin network. As discussed previously, Bitcoin programs written this waymeaning those that do not rely on APIs from external companies and avoid dependencies on separate wallet programsare usually the smartest solution for serious Bitcoin development projects. The Best Programming Language for Connecting to the Bitcoin Network If you're an experienced programmer, most likely you have a favorite programming language you would prefer to use to write your Bitcoin programs. However, only a few mature libraries currently exist that can connect directly to the Bitcoin network. One is the C++ reference implementation with which all the first full clients of the Bitcoin system were written.1 Large enterprise companies interested in supporting bitcoins should use this library. However, working with C++ is difficult for novices. Another mature library is written in Java and is called bitcoinJ.2 Because Java is easier to work with than C++, it is the library we'll use. (The bitcoinJ library can also be used easily from languages built on top of the Java Virtual Machine, such as Scala or Clojure.) Currently, the options for other languages are rather limited. By searching the Internet, you will find Bitcoin libraries for other languages, such as Ruby, C#, and Python. However, most of these libraries are either in extremely early development or simply use the more limited JSON-RPC interface, which was discussed in Appendix A. Some serious attempts are being made to offer full Bitcoin client support within the Go programming language. However, Continue reading >>

    Bitcoin Core Development Falling Behind, Warns Bitcoinj's Mike Hearn

    Bitcoin Core Development Falling Behind, Warns Bitcoinj's Mike Hearn

    Feb 24, 2014 at 05:57 UTC|UpdatedJun 25, 2014 at 17:26 UTC Say what you like about Google, but it isn't an easy place to get hired at. The entrance interviews are notoriously tough, and it is a highly desired employer - which makes Mike Hearn's departure all the more notable. Hearn is an expert in low-level software development, who worked as a site reliability engineer at Google, and focused on account security and antispam. He has also been one of the leading lights in the bitcoin community, heading up the open source development team for bitcoinj , which is the Java implementation of the bitcoin protocol. He is leaving in part because of his growing interest in and commitment to bitcoin. Hearn sees a challenge ahead for the virtual currency: the core development team is shrinking. "The long tail has grown longer, but the heavy lifting and design work has been done by a handful of people. That's quite concerning," says Hearn, highlighting a few key players on the team. He uses the team's page on Github , the open source code repository on which Github is hosted, to see who's most heavily involved. Gavin Andresen, the lead developer, is an obvious mainstay. Others include Philip Kaufmann, who does a lot of GUI development. Wladimir J. van der Laan also works on the front end. "There are occasional fixes and things submitted by other people, but the bulk of the work is being done by Gavin and those guys," says Hearn. "I am a bit concerned by the fact that we don't have a lot of people turning up and doing really serious, useful work on the core." But then, that's a general problem with open source projects. Most people are not paid, meaning that participation can be patchy, and burnout rates can be high. Andresen is paid a salary by the Bitcoin Foundation, and Jeff Gar Continue reading >>
