My project is a patch for Satoshi-client (aka bitcoin-qt/bitcoind). For the present it is more like a Proof-of-Concept than finished application. On the other hand the vanilla bitcoin-client is still beta and nobody worries about that. My client can work in i2p-net using SAM bridge without any third-party libraries. Blocks database is compatible with vanilla client, so you may copy the database from your usual client instead of downloading whole database again.
Installation on Linux (on Ubuntu 12.04 for example):1) add ppa for i2p and bitcoin
sudo apt-add-repository ppa:i2p-maintainers/i2p
sudo apt-add-repository ppa:bitcoin/bitcoin
2) update
sudo apt-get update
sudo apt-get upgrade
3) install packages (java will be installed by dependencies)
sudo apt-get install i2p bitcoin-qt
4) edit this file /etc/default/i2p under root
RUN_DAEMON="true" <- set to true
...
MEMORYLIMIT="xxx" <- specify a value subject to your operative memory (256 or 512 shoud be enough)
5) now run i2p
Installation on Windows:1) download an i2p distribution kit
from official site only:
http://www.i2p2.de/download2) i2p installer will notify you if Java is not installed on your system. If so you should download Java from official site too
http://java.com/download/3) first install Java, then install I2P
4) go to Control Panel - Administrative tools - Services, find "I2P" and check it is running (if it isn't running you should run it)
Running bitcoin in i2p (both Windows and Linux):1) after I2P was running you should wait a few minutes while i2p is integrating in the network
2) in your browser open the page
http://127.0.0.1:7657/configclients. If the page is unavailable that mean I2P was not running (maybe some errors were occured). If the page opens you should press "Start" button near "SAM application bridge" item and enable a checkbox in column "Run at Startup?" After that press "Save Client Configuration" button.
3) delete (or rename) file peers.dat, it's located at C:\Documents and Settings\<YourUserName>\Application data\Bitcoin (for Win XP) | C:\Users\<YourUserName>\Appdata\Roaming\Bitcoin (for Vista and 7) | ~/.bitcoin (for linux).
You must to do this because serialization format of network addresses is incompatible between the vanilla client and my patch. You need to do this procedure only once before the first start of the patched client. The patched client will make his own peers.dat with required format.
Warning! If you leave this file at his place it cause a deadlock of the patched client.
4) download the patched executable files or compile the executable files by yourself and run it
bitcoin-qt -onlynet=native_i2p
If you want to deal with i2p-net only you should specify option -onlynet=native_i2p as shown above. If you want to deal with both i2p and ip(usual internet) don't specify this option at all, in this case you client will be a gate between i2p-segment of bitcoin-net and the rest net.
Notes:
If you want to help other bitcoin users in I2P you may send me or publish here your dest-hash or b32-address and I will add them to the sources as seed-node in a next release. But if you want this you should run your wallet with a permanent i2p-address (see section "Starting wallet with a permanent I2P-address" below)
Changes in command line arguments:1) New command line options are added:
-i2psessionname=<session name> - name of an I2P session. If it is not specified, value will be "Bitcoin-client"
-samhost=<ip or host name> - address of the SAM bridge host. If it is not specified, value will be "127.0.0.1"
-samport=<port> - port number of the SAM bridge host. If it is not specified, value will be "7656".
-mydestination=<pub+priv i2p-keys> - your full destination (public+private keys). If it is not specified, the client will geneterate a random destination for you. See below (Starting wallet with a permanent i2p-address) more details about this option.
-generatei2pdestination - if this option is specified, your client will start for generation i2p-destination only and will close after that.
2) New possible value for "-onlynet" option is added:
3) In all options required IP-addresses now you can specify destination hash: <512 symbols>AAAA or b32-address: <52 symbols>.b32.i2p
Compatibility:1) All of the rest options (except of described above) is not changed and working as they did before
2) Database-file peers.dat is not compatible in both way, neither from vanilla client to my patch, not from my patch to vanilla client. This file must be deleted (or renamed) before using my patch and before going back to vanilla client. This file doesn't contain any important data, so you don't need to back up it.
3) all the rest of databases is compatible with vanilla client.
4) Full backward compatibility of the bitcoin-protocol! Patched client works fine with unpatched vanilla clients. Changes in the protocol are appeared only if both clients are patched.
Starting wallet with a permanent I2P-address:By default if you don't specify -mydestination parameter the patched wallet generates random i2p-destination. It anonymizes your work with bitcoin even more than before. Especially if you use a new bitcoin-address for each transaction. But if you want to help network by publishing you i2p-address or you just like some i2p-address you have to run wallet with permanent i2p-address. You should specify a
full destination in the "mydestination" option for that. Full destionation consists of base64 destionation (b32-address is not allowed here!) and your private tunnel key.
Example:
Run from command line:
bitcoin-qt -mydestination=SVAxpjZzKn~HjvuqpoX5Y948CQnrPpw~9Y9n7itkniijx3NbgTQGJVmZJoc1ERXE87CqcLeeaWtAwqIwhYXL5Y5XkvaUAlAA5BD-9afCmyP42rtEluQLBAprd70UuN20ujuVm0HPyKcIyezphMHsK~GbYMNFiyTz8ko~Kd2wHaeXKWQh6pXyjQJzT4Bwcv1Y9JtPC5b1P5VpwQaLlMJJvblRi8jbRAbimjsxxrMSG6YX8Ks99tsdnQ6YOHGzTPoGpHFgBiROSYwXtC~BbFSv0XfhmN17ZfG6ZCXTbp-xVs-4txSyS~hnS9dL9xHWIv9MNbJzZhI7YztxWgMR3ZNMwR-W2fUeHAcZusmvbm3r-NpIC0O0p9LDDcu7Vxszk~QD~qylFfIT3j8kwu4RDExgqyelVdXVVSlyriHWoIdt9BklqwI1dbAEoLAfG7IZ3921dP4-MH7~AS8Jn3foNe8CAUvu2baRNRIAu75GknCFV5gGIuRRJjFNnrt~vaZfIQP6AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA3HWfbGlqztnwMY3ChbVHkDwJv52n9ElA-cWCRJp8lquVU4H-l2kY5Me1QlpY~7qFy
Or you may use your config-file (bitcoin.conf):
$ cat ~/.bitcoin/bitcoin.conf
mydestination=SVAxpjZzKn~HjvuqpoX5Y948CQnrPpw~9Y9n7itkniijx3NbgTQGJVmZJoc1ERXE87CqcLeeaWtAwqIwhYXL5Y5XkvaUAlAA5BD-9afCmyP42rtEluQLBAprd70UuN20ujuVm0HPyKcIyezphMHsK~GbYMNFiyTz8ko~Kd2wHaeXKWQh6pXyjQJzT4Bwcv1Y9JtPC5b1P5VpwQaLlMJJvblRi8jbRAbimjsxxrMSG6YX8Ks99tsdnQ6YOHGzTPoGpHFgBiROSYwXtC~BbFSv0XfhmN17ZfG6ZCXTbp-xVs-4txSyS~hnS9dL9xHWIv9MNbJzZhI7YztxWgMR3ZNMwR-W2fUeHAcZusmvbm3r-NpIC0O0p9LDDcu7Vxszk~QD~qylFfIT3j8kwu4RDExgqyelVdXVVSlyriHWoIdt9BklqwI1dbAEoLAfG7IZ3921dP4-MH7~AS8Jn3foNe8CAUvu2baRNRIAu75GknCFV5gGIuRRJjFNnrt~vaZfIQP6AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA3HWfbGlqztnwMY3ChbVHkDwJv52n9ElA-cWCRJp8lquVU4H-l2kY5Me1QlpY~7qFy
The first 516 symbols (SVAxp......~vaZfIQP6AAAA) are public key. This key is a base64 i2p-address (aka dest-hash). The rest symbols are private key. If you want to use some i2p-address you need to know its private key. If you publishes you private i2p-key anyone can use your i2p-address. So keep in secret your private key. This program don't send your private key, it uses your key only to open i2p-tunnel. A simplest way to generate your own I2P-address is running the patched client with option -generatei2pdestination. A generated address with a private key will be shown and you will can copy it to your config-file and publish it.
Building from the sources on Linux:0) Install all necessary libraries for bitcoin. No additional dependencies are needed.
1) Go to a root directory of the project and run 1.build-unix.sh
Crosscompillation for Windows on Linux:0) Install mingw32
1) Download and unpack dependencies using script 1.env-setup.sh
2) Build dependencies by script 2.build-deps.sh
3) Build bitcoin with i2p-patch using 3.build-linux-mingw.sh
All builded binaries will be located at <directory with project>/release.
I don't have native windows build scripts, because I use crosscompilation as shown above.
