🚨 Bitcoin Core 31.0 Privacy Bug: Are Your Funds Safe? (What You Need to Know) 🚨

Hey Binancians! ⚠️

If you are running a Bitcoin node or keeping up with the latest tech updates, there is some major news doing the rounds regarding a privacy bug in the newly released Bitcoin Core 31.0.

Before anyone panics—NO, YOUR FUNDS ARE NOT AT RISK. ❌💰

Here is the quick breakdown of what is actually happening, who is affected, and how to stay safe until the 31.1 fix arrives.👇

🔍 What is the Bug?

Bitcoin Core 31.0 introduced a headline feature called privatebroadcast, designed to hide a sender's IP address by routing transactions through Tor.

However, a bug has been confirmed: if the new encrypted v2 (BIP324) connection fails, the node automatically falls back to the older v1 protocol. When this happens, it bypasses Tor and connects directly—leaking your real IPv4 or IPv6 address to the peer. A malicious peer can even force this fallback on purpose.

🛑 Who is Affected?

Relax, most everyday Bitcoin holders, exchange users, and standard hardware wallet users have ZERO exposure here. You are only affected if you are a node operator and meet ALL of these conditions:

Running Bitcoin Core 31.0 with privatebroadcast enabled.

Broadcasting transactions via the sendrawtransaction RPC command.

Have Tor enabled but direct outbound connections unrestricted.

🛡️ What Can You Do Right Now? (Temporary Fixes)

Until Bitcoin Core 31.1 officially drops to patch this flaw, node operators can use these temporary workarounds in their configuration:

Option 1 (Recommended): Turn off the feature entirely by setting privatebroadcast=0

Option 2: Disable v2 transport by setting v2transport=0

Option 3: Force all traffic through Tor by setting proxy=127.0.0.1:9050

💡 Final Thoughts

This is a classic case of responsible disclosure. The bug was found by developer Eugene Siegel, reported safely, and the Bitcoin Core team is already working on the 31.1 update. No private keys are compromised, no wallets can be drained, and the blockchain remains perfectly secure. It's just a temporary hitch for high-privacy node operators.

Stay safe, stay informed, and keep building! 🚀
