![]() ![]() If we want to restart the entire node, then we have to download the entire blockchain again. But keep in mind that this is a one-way trip. Cutting will only take a few seconds or minutes.After enabling this mode, it is not possible to re-scan the wallet, since it is necessary to download the entire blockchain again.This is practically the same as launching a full node wallet. Cutting does not make the security of the wallet less reliable.Before reducing the block size on the nodeīut before you start pruning the size of a running node, you need to know a few important things: This way we can use some Bitcoin Core features, such as a wallet, without having all the old transactions. This is achieved by deleting old information that is not needed when downloading the latest one from the blockchain. This function allows us to run the node, but in its smallest version. To solve the problem when people want to maintain a Bitcoin node, but do not have free space to perform this task, the developers of the Bitcoin core released in version 0.11.0 a feature called “trimming block files”. Given that the block size is approximately 1 MB and that they occur every 10 minutes, it is logical to assume that the growth of the entire blockchain will only grow and grow.īitcoin block size history. The Bitcoin blockchain contains the history of all transactions made daily on the Bitcoin network, from the moment of its creation to the present. In this guide, we’ll look at how it works, and how you can make your own if you’re worried about space. One way to reduce this requirement is to use so-called trimmed nodes, which allows users to run the main wallet without worrying about space. The problem is the resources needed, especially storage space and bandwidth.Ĭurrently, the Bitcoin blockchain weighs almost 390 GB, which is too much for most people who do not have this amount of additional storage. There are lightweight SPV, mobile and hardware wallets, but nothing beats managing a basic wallet. This makes it difficult to maintain a full node for everyone. This not only helps the network, but also has other benefits for the participants.īut since the Bitcoin blockchain is constantly growing, according to, it has reached the point where its overall size has become significant. It is always recommended to run a full node if we want to support Bitcoin and keep the system decentralized. ![]()
