Good morning,
Today, I’m discussing a small improvement to Bitcoin wallet UX that was recently raised on the Bitcoin Development mailing list.
The proposal is an opt-in wallet feature that could make bitcoin self-custody easier for non-English speakers by allowing users to view and input BIP-39 recovery phrases in their native language, while preserving compatibility with the standard English BIP-39 flow.
Even though consensus on larger changes to Bitcoin, such as quantum security, remains elusive, work continues in other ways to make Bitcoin more accessible, usable, and safe for a global audience.
Let’s get into it.
Yours truly,
Christine D. Kim

PR #1255
Category: Bitcoin-core/bitcoin-core.org, the source code for the Bitcoin Core project website.
Title: “posts: add notice about private broadcast IP leak in 31.0”
Author: “andrewtoth”
Status: Merged
Date opened: June 6, 2026
Most recent update: June 11, 2026
What it does: PR #1255 adds a notice to the Bitcoin Core website warning users about a privacy bug in Bitcoin Core 31.0’s new privatebroadcast feature. The notice explains that, under specific network conditions, a transaction broadcast using sendrawtransaction may fall back from a Tor-routed v2 connection to a direct v1 IPv4/IPv6 connection, potentially revealing the sender’s IP address to the receiving peer. A fix is expected in Bitcoin Core 31.1, and the notice gives affected users temporary workarounds.
A more detailed explanation of the bug can be read in this BTC Before Light newsletter.
Why it matters: The bug is not a funds-at-risk issue, but it is important for a narrow set of users who rely on Bitcoin Core v31 to hide their IP address when transacting on Bitcoin.
Last Thursday, developers discussed whether to publicly disclose the bug before a fix is released in Bitcoin Core v31.1. Because the issue had already been discussed publicly at a prior Bitcoin Core developers meeting, developers agreed to publish a formal notice on the Bitcoin Core website and provide temporary workarounds for affected users until the fix is ready.
The discussions about how to properly disclose the bug highlight a recurring tension in open-source software development between transparency and user safety. Because publicly disclosed bugs can be exploited before a fix is available, developers tend to be cautious about discussing and announcing vulnerabilities too early.
In this case, because the bug had already been publicly discussed, it did not put funds at risk, and affected only a limited set of users, developers prioritized alerting users of the privacy risks in v31 as widely as possible ahead of the formal fix.
