🔒 Study: 72% of subsea cables would need to fail to impact Bitcoin Research from the Cambridge Centre for Alternative Finance has for the first time quantified the critical failure threshold of submarine cables required to significantly impact the Bitcoin network. Conducted by researchers Wenbin Wu and Alexander Neumueller using P2P network data from 2014 to 2025 and 68 verified cable failure events, the study finds that between 72% and 92% of all intercontinental submarine cables would need to fail simultaneously before more than 10% of network nodes disconnect. The network shows greater vulnerability to targeted attacks on strategic cable chokepoints, however, with researchers describing this vector as "an order of magnitude more effective" than random failures — a critical threshold of just 5% to 20% of cables could cause substantial disruption if selectively targeted. The study also highlights the role of Tor in strengthening network resilience. With 64% of Bitcoin nodes concealing their physical location through Tor, and relay infrastructure concentrated in well-connected European countries such as Germany, France, and the Netherlands, researchers conclude that "Tor adoption enhances resilience within the current relay geography, rather than introducing hidden fragilities." https://atlas21.com/study-72-of-subsea-cables-would-need-…

Congrats on upgrade, private mode for spark works best..

There is a private 🔒 mode for bitcoin transactions, however not for stablecoins on top of spark. With the private mode that breez SDK has, the spark indexer cannot see it

It would be a very welcome upgrade indeed

True

When spark wallet is implemented in a CORRECT WAY, the privacy mode makes the transactions secret 🔒 enough to stop spark indexer from seeing them. This feature is trivial to implement... using @Breez ⚡️ SDK used by Primal @Cake Wallet has done it this way, as well as @bao markets did in their demo mode

Nvidia predicts making 1 trillion dollars purchase orders in 2027... After $500B last year

When Lora mesh though? Walking around the town like London with Bluetooth turned on is a very bad opsec.. I would rather use easily replaceable lora device connected on the cable with the phone with bitchat installed, and have my GOS in aeroplane mode...

Yes!!

Oh just tried but already claimed Nice offer though
