Cash App: Sorry, your withdrawal could not be processed [LN payment issue] by cointastical in ~bitcoin 1,382 sats and 0 comments so far stacker.news/items/1496281

Martti Malmi, one of Bitcoin's earliest developers, just released a new version of Nostr VPN, an open-source mesh VPN that replaces the entire trust model of traditional VPN services. Traditional VPNs route all your traffic through a central server operated by a company you have to trust. They see your data. They require your email. They can log your activity. They can be subpoenaed, hacked, or shut down. Even modern mesh VPNs like Tailscale, which improved on this by sending data peer-to-peer, still require you to authenticate through a centralized coordination server using third-party accounts like Google or Microsoft. Nostr VPN eliminates the central server entirely. Your identity is a Nostr keypair, a self-generated cryptographic key pair with no registration, no email, no third-party account. The underlying transport layer is FIPS (Free Internetworking Peering System), a self-organizing encrypted mesh network where nodes authenticate each other, route traffic for each other, and establish connections without any central authority or global topology knowledge. Each node's Nostr public key (npub) serves as its network address. The architecture uses two layers of encryption: hop-by-hop encryption between peers and independent end-to-end encryption between mesh endpoints with periodic rekeying for forward secrecy. When direct connections fail due to NAT issues, the system falls back to Nostr-based multihop routing through other FIPS nodes rather than relying on company-operated relay servers. Peer discovery and NAT traversal happen through public Nostr relays using encrypted gift-wrapped messages. The new release adds native desktop apps for macOS, Linux, and Windows, an Android app, Nostr-based multihop routing for when NAT holepunching fails, and improved network management. It supports UDP, TCP, Ethernet, Tor, and Bluetooth transports simultaneously on a single mesh. This is what happens when you apply Bitcoin's design philosophy, permissionless, self-sovereign, no trusted third parties, to networking infrastructure. Built by one of the people who helped Satoshi build Bitcoin in 2009.

Excellent to see Tollgate.me (Community-built Bitcoin-powered WiFi Networks) supported!

Samourai Wallet developer Keonne Rodriguez sentenced to 5 years in federal prison, the maximum penalty, prosecutors allege laundered $237M.

RT @1914ad: @Excellion Inb4 someone tells us how cheap storage is and therefore Bitcoin should be repurposed.

Running Knots means: ✅ Lower resource usage ✅ Cleaner mempool ✅ Less exposure to spam and illicit data

Core’s philosophy is neutrality: “If it pays the fee and follows consensus, relay it.” Knots says: “Let’s not relay junk that bloats the network.”

This isn’t censorship. Knots still accepts valid blocks. It just refuses to relay or display non-monetary transactions like NFTs, Ordinals, or Runes.

Here's a demo video showing a mobile user connecting to a revenue-generating (bitcoin) Tollgate.me Wi-Fi hotspot: Now w/ Raspberry Pi 4b support (v0.0.4-beta2)! Video source (with link to the video in 10 other languages): stacker.news/items/1017117

v0.0.3 of Tollgate OS (Bitcoin-enabled hotspot) is out Now, with LN payout github.com/OpenTollGate/toll… Tollgate.me

v0.0.2 of Tollgate OS is out github.com/OpenTollGate/toll… Tollgate.me

One of surprises today was how well #meshtastic network worked for me during Portugal power outage. Thanks to my node I had enough information about what's going on even when I had no other connectivity (no TV, cellular, internet).

Bitcoin just got a tap-to-pay upgrade. @CashuBTC now lets you send #Bitcoin offline via NFC, no internet, no delay. Private, instant, open-source.

Last Week in Bitcoin: “The Mempool” cleared out… 🤦‍♂️ With @LukeDashjr, @wk057 and @GrassFedBitcoin The guys breakdown some fundamental principles of Bitcoin and how they relate to widespread misunderstandings around mempools, small blocks, and solo-mining.

For this, I merged github.com/sipa/bitcoin-seed… into the master branch.

Quick #Bitcoin tidbit: When people started reporting Tor node counts dropping, I started measuring them myself. In only a brief period of time, I've successfully connected to over 10k onion nodes. Seems like nodes probably haven't gone anywhere; it's just a bug in whatever people are trusting to count them.
