In #BitcoinCore , a vulnerability CVE-2024-52911 was patched — this is the first memory safety bug that was squashed in the client. The fix was rolled out before the public disclosure of the vulnerability this week.
The issue affected Bitcoin Core versions from 0.14.0 to 28.x and allowed miners to remotely crash nodes by sending invalid blocks. It's estimated that about 43% of active nodes were still vulnerable prior to the patch $BTC

🚨 Bitcoin Core just disclosed a high-severity bug that could let miners crash your node or worse, execute code on it.
It was patched quietly.
Months before anyone was told.
And thousands of nodes may still be running the vulnerable version.
This isn't a minor glitch.
A use-after-free vulnerability in the script validation engine the core of how Bitcoin verifies transactions is about as deep as bugs get.
This is the engine room. And it had a hole in it.
Use-after-free means memory that's already been freed gets accessed again.
In the wrong hands, that's not just a crash.
That's arbitrary code execution meaning a bad actor could potentially run their own code on your node.
On a Bitcoin node.
Let that land.
The patch was silent by design.
Bitcoin Core developers quietly shipped the fix months ago standard protocol for critical vulnerabilities.
You don't announce a live exploit before most people have patched.
But that window? It existed. And not everyone closed it.
Here's the part that should make every node operator check their version right now.
Bitcoin's security model depends on a decentralized network of nodes independently verifying the chain.
Crash enough nodes at the right moment or worse, compromise them and that independence becomes a fiction.
Bitcoin didn't break.
The protocol held. The patch worked. This is the system functioning as designed.
But it's a reminder that Bitcoin's real attack surface was never the blockchain.
It was always the software running underneath it.
Check your node version.
Update before someone else does it for you.

Red alert for exchange and wallet users! 🚨
This morning in crypto isn't just about green candlesticks, but also important warnings:
Bitcoin Core vulnerability: If you're running your own node, check for updates immediately. The RCE (remote code execution) vulnerability is no joke – 43% of the network is still at risk!
Local issues: We're hearing about delays in withdrawals on popular platforms in Poland. Remember the golden rule: Not your keys, not your coins. Transfer your excess to hardware wallets.
Attack on Ekubo: $1.4 million vanished due to a logic error in the contract. DeFi can still be the "Wild West."
Stay safe and double-check addresses! 🛡️

Important update for Bitcoin users! 🚀
The Bitcoin Core developers have released version 31.0, with a focus this time on the network's intelligence in handling pending transactions (Mempool).
What's new in this update? 🤔
Smarter estimation: Nodes are now more accurate in estimating the value of related transactions, which speeds up the decision to pass or confirm them.
Higher privacy: The Private Broadcasting feature gives you additional security, allowing you to send your transactions via Tor or I2P to completely hide your geographical location and IP address. 🛡️
Who benefits?: If you use Lightning Network or complex wallets that support RBF and CPFP, you will notice a clear difference in the speed and acceptance of your transactions.
Bitcoin is continuously evolving to become more private and efficient. Technical updates are the backbone of this network's strength! 💪

Bitcoin just got a major privacy upgrade. Most people have no idea.
Bitcoin Core v31.0 now routes transactions through Tor by default. Your IP is hidden. Your identity is protected. This is not just a tech upgrade — it's Bitcoin becoming uncensorable money. Quietly bullish.
