00:00Hey everyone, welcome back. Today we're breaking down everything you need to know about the brand

00:04new Bitcoin Core V30 update. Bitcoin Core V30 is just around the corner. The release candidate

00:10came out on September 12, 2025, and if all goes well, the official release drops on October 3rd.

00:15Let's start with the major changes. The signature operation limit per transaction is now 2,500

00:21CEPs. The OP return size limit has been raised to about 100 kilobytes, which means transactions

00:26can now include multiple OP return outputs. The defaults have also been adjusted. Mint fee

00:31lower to 0.1 sat per vbyte, and relay an incremental relay fee set at 0.1 sat per vbyte.

00:37If you run a prune node, there is something important to know. Rebuilding the coin stats

00:41index under the new format could take a long time. Some users are already working around

00:46this by copying indexes from faster nodes instead of starting from scratch. Now let's talk about

00:50the bigger picture. This update hasn't come without controversy. The relaxed OP return limits

00:55are a hot topic. Some developers argue it could lead to spam, censorship issues, or even

01:00vehementation of the network. In fact, reports suggest that around 3,000 nodes, about 13%

01:06of the network, might average on relay policy, creating potential compatibility problems.

01:11So what should you do? If you operate a node, help test the release candidate and share feedback.

01:16If you run a prune setup, prepare for a slow index rebuild. And for everyone else, keep an eye

01:20on how this plays out especially around the OP return debate. That's it for Bitcoin Core v30.

01:26Big changes, big debates, and the release just around the corner. If you found this useful,
