This software reads the Bitcoin block file, transforms and loads the data into a database, and presents a web interface similar to Bitcoin Block Explorer, http://blockexplorer.com/.
Abe draws inspiration from Bitcoin Block Explorer (BBE) and BlockChain.info and seeks some level of compatibility with them but uses a completely new implementation.
Issue:
python setup.py install
This will install abe to your system. After you set up the config file and database (see below and README-.txt) you can run:
python -m Abe.abe --config myconf.conf --commit-bytes 100000 --no-serve
This will perform the initial data load and will take a long time. After it's fully synced, you can run the web server with:
python -m Abe.abe --config myconf.conf
To really get everything right see the README file for your type of database.
Abe depends on Python 2.7 (or 2.6), the pycrypto package, and an SQL database supporting ROLLBACK. Abe runs on PostgreSQL, MySQL's InnoDB engine, and SQLite. Other SQL databases may work with minor changes. Abe formerly ran on some ODBC configurations, Oracle, and IBM DB2, but we have not tested to be sure it still works. See the comments in abe.conf about dbtype for configuration examples.
Abe works with files created by the original (Satoshi) Bitcoin client. You will need a copy of the block files (blk0001.dat, blk0002.dat, etc. in your Bitcoin directory or its blocks/ subdirectory). You may let Abe read the block files while Bitcoin runs, assuming Bitcoin only appends to the file. Prior to Bitcoin v0.8, this assumption seemed safe. Abe may need some fixes to avoid skipping blocks while current and future Bitcoin versions run.
NovaCoin and CryptoCash support depends on the ltc_scrypt module available from https://github.com/CryptoManiac/bitcoin-abe (see README-SCRYPT.txt).
Hirocoin (and any other X11) support depends on the xcoin_hash module available from https://github.com/evan82/xcoin-hash.
Bitleu (a Scrypt-Jane coin) depends on the yac_scrypt module.
Copperlark (a Keccak coin) depends on the sha3 module available via "easy_install pysha3".
The GNU Affero General Public License (LICENSE.txt) requires whoever modifies this code and runs it on a server to make the modified code available to users of the server. You may do this by forking the Github project (if you received this code from Github.com), keeping your modifications in the new project, and linking to it in the page template. Or you may wish to satisfy the requirement by simply passing "--auto-agpl" to "python -m Abe.abe". This option makes all files in the directory containing abe.py and its subdirectories available to clients. See the comments in abe.conf for more information.
For usage, run "python -m Abe.abe --help" and see the comments in abe.conf.
You will have to specify a database driver and connection arguments (dbtype and connect-args in abe.conf). The dbtype is the name of a Python module that supports your database. Known to work are psycopg2 (for PostgreSQL) and sqlite3. The value of connect-args depends on your database configuration; consult the module's documentation of the connect() method.
You may specify connect-args in any of the following forms:
-
omit connect-args to call connect() with no arguments
-
named arguments as a JSON object, e.g.: connect-args = { "database": "abe", "password": "b1tc0!n" }
-
positional arguments as a JSON array, e.g.: connect-args = ["abe", "abe", "b1tc0!n"]
-
a single string argument on one line, e.g.: connect-args = /var/lib/abe/abe.sqlite
For JSON syntax, see http://www.json.org.
Reading the block files takes much too long, several days or more for the main BTC block chain as of 2013. However, if you use a persistent database, Abe remembers where it stopped reading and starts more quickly the second time.
Abe does not currently handle block file changes gracefully. If you replace your copy of the block chain, you must rebuild Abe's database or (quicker) force a rescan. To force a rescan of all data directories, run Abe once with the "--rescan" option.
By default, Abe expects to be run in a FastCGI environment. For an overview of FastCGI setup, see README-FASTCGI.txt.
To run the built-in HTTP server instead of FastCGI, specify a TCP port and network interface in abe.conf, e.g.:
port 2750
host 127.0.0.1 # or a domain name
To display Namecoin, NovaCoin, or any block chain with data somewhere other than the default Bitcoin directory, specify "datadir" in abe.conf, e.g.:
datadir = /home/bitcoin/.namecoin
The datadir directive can include a new chain's basic configuration, e.g.:
datadir += [{
"dirname": "/home/weeds/testnet",
"chain": "Weeds",
"code3": "WDS",
"address_version": "o" }]
Note that "+=" adds to the existing datadir configuration, while "=" replaces it. For help with address_version, please open doc/FAQ.html in a web browser.
The web interface is currently unaware of name transactions, but see namecoin_dump.py in the tools directory.
Please see TODO.txt for a list of what is not yet implemented but would like to be.
