This will create or open the underlying store.ĭb.Blockdaemon is the Total Node Management Solutionīlockdaemon guarantees peace of mind, as you never have to worry about maintaining or upgrading your nodes ever again - we look after all of that for you. 1) Create our database, supply location and options. Create a file called index.js that contains the following code.

Create a directory for hosting our code.

A primer on leveldbīefore we look at these in more details, let's first familiarise ourselves with leveldb using nodejs. The sorting is one of the main distinguishing features of LevelDB amongst similar embedded data storage libraries and comes in very useful for querying as we’ll see later. We will be using LevelDB, a light-weight, single-purpose library for persistence with bindings to many platforms used by bitcoin core for storing this data.īy default, LevelDB stores entries lexicographically sorted by keys. Some background on key storeįor the purpose of this tutorial, we'll be having a closer look at the blocks and chainstate directories and files.

addr.dat: peer IP address database (BDB) replaced by peers.dat in 0.7.0Īs we can see, there are various files and directories which organise data behind our node, so let's take a closer look at each of these.

blk000?.dat: block data (custom, 2 GiB per file) replaced by blocks/blk000?.dat in 0.8.0.

blkindex.dat: block chain index database (BDB) replaced by in 0.8.0.

coins/ unspent transaction output database (LevelDB) since pre-0.8, replaced by chainstate/ in 0.8.0.

blktree/ block chain index (LevelDB) since pre-0.8, replaced by blocks/index/ in 0.8.0.

Mac OS X ~/Library/Application\ Support/Bitcoin/ $ tree ~/.bitcoin/īy default, bitcoind will manage files in the following locations. Gr0kchain:~ $ docker run -v bitcoind-data:/bitcoin -name=bitcoind-node -d \īefore we get started, let's have a look at the data directory of an existing running bitcoin core node. gr0kchain:~ $ docker volume create -name=bitcoind-data

Īlternatively, we have also provided a simple docker container configured in regtest mode that you can install for testing purposes. If you don't currently have access to a bitcoin development environment set up, dont' worry, we have your back! We've setup a web based mechanism which provisions your very own private session that includes these tools and comes preconfigured with a bitcoin node in regtest mode. You can however execute these against either the testnet or mainnet configurations. We suggest executing against a node configured in regtest mode so that we can have the freedom of playing with various scenarios without having to loose real money. Having a better understanding of how this is managed allows us to overcome probing bitcoin's remote procedure call (RPC) and REST based interfaces for insights into the data maintained by the client.

In this tutorial, we will be taking a closer look at the data directory and files behind the Bitcoin core reference client.
