In bitcoin application development, a common problem is how to query all transactions that take place at that address when you know the bitcoin address. Or similarly, how do you query all transactions that take place at a given bitcoin address? This article will give three solutions to this problem.

1. Store the bitcoin transaction data in the database

Because of the data storage structure of Bitcoin, it is impossible to directly use the original API of Bitcoin to query the historical transaction data of the specified address. So the most simple (Naive) first solution is to store each transaction data on the bitcoin blockchain in its own database, and then index the transaction address information (such as Scriptpubkey, pubkey, or the address itself) so that it can be queried freely and efficiently on the database.

2. Make use of third-party services

The naive first solution requires you to parse the bitcoin blockchain data and build your own database environment, which you may find a bit troublesome. Fortunately, many third-party organizations have done this tedious thing and provide it in the form of open API, which you can use directly.

For example, you can use blockchain.info 's api to do this:

$curl https://blockchain.info/rawaddr/$bitcoin_address3, another bitcoin node implementation software

If you don't want to create your own database or use a third-party open API, there is a third solution, which is to replace the node implementation software that supports querying transactions by Bitcoin address, such as btcd, which is a Bitcoin node software implemented in the go language. When you start btcd, you can automatically build a bitcoin address index by using the-addrindex flag:

$btcd-addrindex

The three solutions listed in this article for querying historical transactions with bitcoin addresses are suitable for different application scenarios, and you can make your own choices according to your needs.
