New design and specifications come with the X-button
BARCELONA, Spain, February 27, 2019 : Six months  after launching an opoerating system for a secure mobile phone harnessing blockchain technology, the Singapore-based makers, Pundi X   have unveiled a handset -- the XPhone at the Mobile World Congress.( our earlier story here)
It uses a blockchain-based OS and communication protocol for mobile devices, allowing users to make calls, send messages, and transmit data via a fully decentralized blockchain network.On blockchain mode, the XPhone can operate completely independently of centralized carriers. Users can route phone calls, messages, and data via blockchain nodes without the need for centralized service providers. The XPhone is in fact the first mobile phone that can run completely on a decentralized ecosystem powering telephony, messaging, and data transmission. The XPhone significantly expands the use of blockchain technology beyond financial transfers.
|Every XPhone is also a node on the network to contribute to the operation of the blockchain ecosystem. Content and connectivity are organized in a distributed, node-to-node manner.|
The key feature of the rollout version of the XPhone showcased in Barcelona is the “X” button that allows users to have direct access to the Dapps on the blockchain mode
 “What this all means is that data control can and must be given back to users,” said Pundi X Co-founder and CEO Zac Cheah, “Telecommunications and Internet companies have derived tremendous value from controlling data. By decentralizing apps, we can put this data onto a smart contract, effectively giving control back to creators and users. Much of what we call peer-to-peer or ‘decentralized’ services continue to be built upon centralized networks. We are changing that.”
Mobile devices as nodes
"Scalability in blockchain is derived from the number and geographic spread of nodes. It is clear how achieving a critical mass in terms of scale will require something with a high utility for people. The XPhone thus has the potential to establish a large global pool of nodes,” said Pitt Huang, Co-founder and CTO of Pundi X.
