The setup can support 18,000 simultaneous wi-fi connections, while a distributed antenna system (DAS) boosts mobile phone coverage in the stadium. "So, you know your phone will work," says Phil Davies, IT Director at Everton Football Club.
At the core of Linux ID is a set of cryptographic "proofs of personhood" built on modern digital identity standards rather than traditional PGP key signing. Instead of a single monolithic web of trust, the system issues and exchanges personhood credentials and verifiable credentials that assert things like "this person is a real individual," "this person is employed by company X," or "this Linux maintainer has met this person and recognized them as a kernel maintainer."

Technically, Linux ID is built around decentralized identifiers (DIDs). This is a W3C‑style mechanism for creating globally unique IDs and attaching public keys and service endpoints to them. Developers create DIDs, potentially using existing Curve25519‑based keys from today's PGP world, and publish DID documents via secure channels such as HTTPS‑based "did:web" endpoints that expose their public key infrastructure and where to send encrypted messages.
This is the best power bank for laptops. It can deliver up to 300 watts and has three USB-C ports (140W, 65W, 65W) as well as a retractable 2-foot USB-C cable (140W). There's a display that shows handy information like remaining battery life and different charging rates. The power bank can also be topped off from dead to 80 percent full in under half an hour if you plug in both USB-C ports. Even if you don't opt for the absolute fastest recharge speeds, you'll still be able to top it off in about an hour—no more waiting overnight for your power bank to recharge.
