We are winding down the hosted service toshi.io, and it will be fully retired on Dec 15th, 2016. The open source code will stay available on github.
Toshi is a complete implementation of the Bitcoin protocol, written in Ruby and backed by PostgreSQL. It provides a RESTful API that is ideal for building scalable web applications or analyzing blockchain data.
Toshi is designed to be fully compatible with Bitcoin Core. It performs complete transaction and block validation, and passes 100% of TheBlueMatt's regression test suite. For much of the core protocol logic, Toshi makes use of the bitcoin-ruby library written and maintained by Julian Langschaedel.
Toshi was built at Coinbase, with the goal of replacing our core Bitcoin network infrastructure in the near future. It is currently in beta, and not recommended for production use until it has received sufficient testing from the Bitcoin community.
You can see Toshi running on various networks at the following URLs:
A Bitcoin node is simply a client on the Bitcoin peer-to-peer network. It validates and relays transactions and blocks to other clients according to the consensus rules as implemented in Bitcoin Core. A "full node" implies that the client retains a complete copy of the Bitcoin blockchain.
Toshi is a Bitcoin implementation designed for building highly scalable web applications. It allows you to query the blockchain using a REST API or raw SQL. It comprises a number of individual services, using a shared database. Because Toshi saves much more information and indexes more data than Bitcoin Core, it requires much more space to store the blockchain (~220GB vs ~25GB as of September 2014). However, this makes it possible to run much richer queries that would otherwise not be possible with Bitcoin Core.
Bitcoin Core (the reference implementation) is designed to run on a single server, and uses a mixture of raw files and LevelDB to store the blockchain. It allows you to query the blockchain using a JSON-RPC interface.
Some examples of queries which Toshi can easily answer, which are not possible with Bitcoin Core:
Coinbase maintains a hosted version of Toshi that you can use at:
This is the easiest way to get up and running. You can also run your own version of Toshi as described below.
$ git clone https://github.com/coinbase/toshi.git $ cd toshi
$ docker-compose build $ docker-compose up -d db $ docker-compose run web bundle exec rake db:create $ docker-compose up -d $ open localdocker:5000 # use `boot2docker ip` for the address if using boot2docker
You can run the test suite for Toshi as follows:
$ git submodule init $ git submodule update $ docker-compose build $ docker-compose run -e TOSHI_ENV=test web bundle exec rake db:create $ docker-compose run -e TOSHI_ENV=test web bundle exec rspec
Toshi can import the standard
bootstrap.dat file that bitcoind uses to load
the beginning of the blockchain using the
export BOOTSTRAP_FILE=/path/to/bootstrap.dat export TOSHI_ENV=production ./bin/bootstrap.rb
Toshi can be deployed directly to Heroku:
After it is deployed, you can start syncing with the following command:
$ heroku ps:scale web=1 peer_manager=1 block_worker=1 transaction_worker=1
For more detailed Heroku deployment instructions you can read this page.
Toshi can also be installed on your own server. You will need:
To run Toshi on your server, simply:
$ git clone https://github.com/coinbase/toshi.git $ cd toshi $ cp config/toshi.yml.example config/toshi.yml $ vi config/toshi.yml $ REDIS_URL=redis://... DATABASE_URL=postgres://... TOSHI_ENV=production bundle exec foreman start
Note: The Toshi API provides raw blockchain data only. If you are looking for APIs to store bitcoin securely, buy/sell bitcoin, send/request bitcoin, accept merchant payments, etc) please check out the proprietary Coinbase API.
The API supports three data types by adding an extension on any URL.
.json - JSON (default if none specified)
.hex - raw binary, in hex form
.bin - raw binary
For GET requests, the extension specifies the format of the returned data. For POST/PUT requests, the extension specifies the format of the request body.
Any API call which returns as list can also be passed an
limit parameter. The default
limit is 100.
# Blocks GET /api/v0/blocks # Get a paginated list of blocks GET /api/v0/blocks/<hash> # Get a block by hash GET /api/v0/blocks/<height> # Get a block by height GET /api/v0/blocks/latest # Get the latest block GET /api/v0/blocks/<hash>/transactions # Get transactions in a block # Transactions GET /api/v0/transactions/<hash> # Get transaction by hash GET /api/v0/transactions/unconfirmed # Get list of unconfirmed transactions POST /api/v0/transactions # Broadcast a transaction to the network # Addresses GET /api/v0/addresses/<hash> # Get address balance and details GET /api/v0/addresses/<hash>/transactions # Get address transactions GET /api/v0/addresses/<hash>/unspent_outputs # Get unspent outputs on an address
config/toshi.yml according to its current environment (determined by the
TOSHI_ENV environment variable). Toshi will default to the
development environment if one isn't specified and the
test environment during rspec tests.
Toshi will use the
config/toshi.yml.example file if the
config/toshi.yml file does not exist.
