The leading provider of the crypto-based location technology XYO Network with its office in San-Diego has recently acquired a Proof-of-Location protocol developing startup GEO. GEO is a unique small company in the sense that 3 students with the renowned hacker Jack Cable have been able to develop a location providing protocol that makes sharing anybody's location easy in a decentralized network without the cost of an overhead.

We're excited about the addition of GEO to our crypto-location portfolio. GEO adds an additional feature set to XYO by trustlessly notifying a device that an object was there with absolute certainty, and without having to communicate private data with the network.

Co-Founder, XYO Network

GEO relies on a network of physically fixed devices called Nodes. Users may connect via Bluetooth to a Node and get a Proof-of-Location signature. User device ID and timestamp are used to generate the signature, basically answering the questions "WHo, when and where?". The protocol is built on Ionic platform and utilizes Bluetooth which combined makes it cross-compatible with any mobile system. Probabilistic Proof-of-Location is essential for applications in e-commerce (shipment tracking), automated drones communication and hospitals (communication failure and record keeping). Therefore, GEO offers a special smart contract model for such use-cases.

XYO Network and GEO have already granted free access to some of the libraries so that developers can develop and test software of GEO platform. XYO Network developed world's first decentralized location verification system for Ethereum, and it seems open ecosystem of geospatial blockchain applications pose a formidable alternative to GPS.

Ledger hardware wallet developers stated that an unforeseen problem was found in software version 1.5.5 for the Nano S model. Improvements in the security context have affected the amount of device memory.

When planning for this update we didn’t anticipate the impact it would have on Ledger Nano S capacity. This was not planned obsolescence, simply put, we messed up. We apologize and we’re committed to making it right.

Ledger Team

The project team apologized for the incident and promised to fix the problem during the second quarter of 2019.

The project also announced the addition of Nano S support in the Ledger Live mobile app on Android.

Earlier, researchers at discovered a number of vulnerabilities in the Trezor and Ledger hardware cryptocurrency wallets. As a result, they were able to conduct a series of successful attacks on wallets during the Chaos Communication Congress in Leipzig.
