Bitseed Broadcast, Issue #17

Welcome to Issue #17 of the Bitseed Broadcast, a newsletter published by the Bitseed team to share important news for Bitcoin full node operators. We cover the latest in Bitcoin development, full node news, community events, and experimental projects that node operators may find of interest. If you have any news tips or insights you’d like us to share in a future edition of the Bitseed Broadcast, send us a message and we’ll credit you if your submission is published. Here’s the latest:

How to remove Bitseed’s blockchain backup

As the blockchain has grown in size, we’ve been hearing from customers who purchased the Bitseed v1 developer units last year that hard drives are now completely full. In the last Bitseed Broadcast, we shared our trade-in deal that lets customers upgrade their Bitseed to get a bigger hard drive. However some customers have expressed that they want to keep their Bitseed, and would instead prefer to free up hard drive space if possible instead of trading in for a bigger hard drive. One way to free space is to disable the blockchain backup.

Every Bitseed (with the exception of Bitseed Lite models) comes with a complete blockchain backup. This is to prevent long re-synchronization times in the case of blockchain database corruption due to unexpected power failures or other issues. Without a backup, re-synchronization could take weeks on Bitseed’s hardware. A backup makes it fast and convenient to pick up where the device left off before a corruption incident, but also doubles the storage requirements of the Bitcoin blockchain. By removing the backup, we can free up a significant amount of space at the cost of convenience should the blockchain database be corrupted. This past weekend, Bitseed engineer Jay Feldis published a guide with instructions for disabling the backup feature and removing the blockchain backup. Following these instructions will free up about 60GB of space. You can find the instructions for disabling blockchain backups in the link below.


Bitcoin Core 0.12.1 released

The Bitcoin Core team has released the latest version of the Bitcoin Core software, v0.12.1. According to the blog post announcing this release:

This maintenance update includes the first soft fork deployment utilising “version bits” as part of the capacity increasesroadmap.

The soft fork seeks to activate three BIPs: BIP68 sequence locks, BIP112 OP_CHECKSEQUENCEVERIFY and BIP113 Median time past, which together are known as the “csv” deployment. Signalling begins at midnight on May 1st, 2016.

Bitseed owners can find the update binaries here. Instructions for installing will be posted on the Bitseed blog this coming week.


Peter Wuille submits Segregated Witness pull request

After months of testing on SegNet, Bitcoin developer Peter Wuille has submitted a pull request to the Bitcoin Core repository to add support Segregated Witness. This will be a soft-fork change that implements a new way for moving data throughout the Bitcoin network by separating the signatures from the block data. This fixes a number of long-standing issues, such as transaction malleability UTXO growth, and also has a side benefit of effectively increasing the block size limit from 1MB to nearly 4MB. You can review the pull request and learn more about Segregated Witness in the links below.
