Bitcoin Core Wallet Review: Features and How-to-Use Guide

BDK wallet developer library can be used to easily deploy wallets with various kinds of blockchain backend support, like electrum opens new window , esplora opens new window , compact-filters BIP opens new window etc.

With the latest release of BDK v0. BDK talks with Bitcoin Core using rust-bitcoin's bitcoincore-rpc opens new window library. This allows wallet devs to quickly deploy their wallet that can talk to a bitcoin full node home raspi nodes out of the box.

Wallet devs don't need to worry about connecting to a full node with correct RPC calls, all of that is handled by BDK under the hood. In this tutorial we will see how to write a very simplistic wallet code that can connect to a bitcoin core node and maintain its balance and make transactions.

Unlike other tutorials, we will not use bdk-cli tools, but instead write rust code directly using BDK devkit. In the end we will end up with our own simple bitcoin wallet. To run with this tutorial you would need to have a bitcoin core node running in regtest mode. Get the bitcoin core binary either from the bitcoin core repo opens new window or build from source opens new window. Apart from that, you would need to install rust in your system. Grab the installation one-liner from here opens new window.

Try running cargo run and if everything is set, you should see "Hello, world! Of course we will not use the given println! Once the rust binary is compiled and running, we now need to specify the dependencies we need to work on our library. Remember that BDK provides almost everything we would need to build a wallet out of the box. So we don't need any more dependencies apart from BDK. We disabled the default BDK feature which specifies blockchain backend as an electrum server and we requested the following features:.

Now that we have the dependcies added, we can import them in the main. Add the following imports at the start of main. BDK is a descriptor based wallet library. That means when we specify our wallet key-chain we need to tell BDK about it in the format of a descriptor.

You can read up on descriptors more here opens new window. If you already have a descriptor from other sources, you can use that. Otherwise, BDK has your back. BDK can be used to generate a fresh master key with mnemonic, and then derive child keys from it given a specific path.

Putting the key in a descriptor is as simple as wrapping it with a wpkh string. We will use a dedicated function that will create fresh receive and change descriptors from BDK for our purpose.

It will also generate the mnemonic word list for later regenerating the wallet. But we will ignore that for our scope. Add a function named get-descriptor below the main function as shown. To check that the above added function is working as expected, call it in the main function and print the descriptors.

Like all other tutorials we will use two wallets to send coins back and forth. But unlike other tutorials, we won't be using bitcoin-cli to talk to the Core wallet we can, but let's spice things up. Instead, we will use the bitcoin-rpc library, to talk with our core node listening at This will allow us to write code, that will handle both the core and BDK wallet, from inside of the same function, and we won't have to switch terminals!

Thats exactly for this purpose. We have provided our RPC authentication username and password same as provided in bitcoin. We have provided the RPC address of our local bitcoin node, with the path to a wallet file, named test. And then asked the rpc client to give us the current blockchain info. If everything goes well, running cargo run you should see an output like below:. We have told our rpc client that we would use a wallet named test. But currently, our core node doesn't have such a wallet.

So let's create the wallet and fund it with some test coins. This will create a wallet in bitcoin core named test. Because required coinbase maturity in bitcoin is blocks, by generating blocks, we will have the balance of the first coinbase block reward available for use. The last println! Now that we are done setting up the core wallet. The last remaining step is to setup the BDK wallet.

For this we will use the previous descriptor generation function and write code as below. Note : You might want to comment out the previous code in main , as running them again will create more coins in core, which isn't an issue, but might be confusing. That's a lot of code. They are divided into logical sections. Let's discuss each step one by one. Now that we have a our wallet cooked, in the end, we instructed it to sync with the bitcoin core backend, and fetch us a new address.

Now that we have covered all the groundwork, we have all we need to send coins back and forth between core and BDK wallet. In the last line of previous section we got a new address from BDK wallet. We will start from there. Without further discussion lets jump straight into code. The above code segment is mostly straight forward. The only new thing added is wallet.

BDK allows us to have very fine grained control of cooking up transactions. Almost everything that is possible to do with a Bitcoin transaction can be done in BDK.

Here we have a very simple vanilla transaction with no added magic. To get full list of capabilities that TxBuilder supports scour its implementation here opens new window. The slight deficiency in the amount are due to transaction fees. Because we are using regtest, the fee is some standard value hardcoded in core node.

In this tutorial we saw some very basic BDK wallet functionality with a bitcoin core backend as the source and sync of blockchain data. This is just tip of the iceberg of BDK capabilities. BDK allows flexibility in all the dimensions of a bitcoin wallet, that is key chain, blockchain backend and database management. With all that power, we just implemented a trustless, non-custodial, private bitcoin wallet, backed by a bitcoin full node, with less than lines of code including lots of comments.

BDK thus allows wallet devs, to only focus on stuff that they care about, writing wallet logic. All the backend stuff like blockchain, key management, and databases are abstracted away under the hood. To find and explore more about the BDK capabilities and how it can fit your development need refer the following resources.

Introduction BDK wallet developer library can be used to easily deploy wallets with various kinds of blockchain backend support, like electrum opens new window , esplora opens new window , compact-filters BIP opens new window etc. Prerequisite To run with this tutorial you would need to have a bitcoin core node running in regtest mode. Then configure the node with a following bitcoin.

Bitcoin was first conceptualized by the legendary Satoshi Nakamoto, who designed the open-source software and P2P network on which the Bitcoin blockchain was built. Bitcoin is a type of P2P-based virtual encrypted digital currency. Bitcoin uses a SHA encryption algorithm and has a total of 21 million blocks. Typically, one block is generated every 10 minutes and the reward is cut in half every , blocks.
