What Ziber does

Ziber LTD is a UK-incorporated private company founded in 2017 that operates a blockchain-based decentralized VoIP telecommunications platform. The company deploys a global network of masternodes and routes calls through Android and iOS smartphones acting as proxy servers, leveraging mobile subscribers' existing free in-network minutes to deliver what it describes as zero-cost call carriage. Its product portfolio comprises the Ziber Mobile Application, a Windows PC client, and the Ziber Token, an ERC-20 token on Ethereum (contract 0xAb98922CA2be48214539c7D5Dc63a343d14d7227), with source code published on GitHub.

The business model is twofold. First, Ziber charges a per-minute fee on calls to mobile and landline numbers — set materially below Skype and Viber (e.g., $0.01/min to the US, UK, Brazil, Australia, Singapore versus Skype's $0.023-0.043) — on the premise that cost of goods sold is effectively zero for proxy-routed calls. Second, a portion of call revenue is distributed to masternode operators and to mobile users who provide their devices as proxy servers. The company conducted an ICO on July 27, 2017, issuing 100 million tokens with 80% sold publicly, 10% to the team (frozen for one year), and 10% distributed as a bonus to Bitcoin and Ethereum holders. Target raise was £1-10 million, with proceeds earmarked for promotion, additional offices, server capacity, and multi-jurisdiction legal hires.

Ziber targets three horizontal segments: general consumers seeking lower-cost international calls, cryptocurrency holders seeking utility for token holdings, and server/IT operators seeking returns on masternode infrastructure. Distribution is self-serve through mobile app stores, GitHub downloads, and cryptocurrency exchange listings. The dataset is entirely from the 2017 ICO era; no subsequent funding, customer, or revenue data are available, and current operational status cannot be verified from the provided material. The company was a four-founder team (Mark Braun, Michail Kaufman, Jason White, Michael Cordy) with no disclosed broader headcount.

Core offering

Ziber provides a decentralized blockchain-based VoIP calling platform that routes international calls through mobile phones acting as proxy servers on a global masternode network. Users download the Ziber mobile app (Android/iOS) or Windows desktop program to make international calls at significantly lower rates than Skype or Viber, while smartphone owners can earn by serving as proxy servers for call routing. The Ziber token (ERC-20 on Ethereum) serves as the platform's economic layer, with revenue from call charges redistributed to masternode operators and proxy server providers.

Product overview

Ziber is a blockchain-based mobile operator offering a decentralized VOIP telecommunications platform. The product portfolio consists of three core offerings: the Ziber Mobile Application (available on Android and iOS) for decentralized peer-to-peer calling, the Ziber Windows PC Program for desktop users requiring calling and blockchain operations, and the Ziber Token (ERC-20 on Ethereum) which serves as the economic engine of the ecosystem. The platform operates through a global network of masternodes installed on servers worldwide, allowing smartphone owners to earn by serving as proxy servers for call routing. Call costs are significantly reduced compared to traditional VOIP services like Skype and Viber, targeting the $90 billion telecommunications market.

Broad incumbents

• WhatsApp (Meta): Free end-to-end encrypted voice calling inside a messaging app used by billions. Compresses Ziber's addressable market by making peer-to-peer voice calls effectively free for the vast majority of personal contacts.
• Telegram: Messaging platform with integrated voice calling and a token (TON) economy, offering a comparable combination of free calls plus crypto-native incentives that overlaps with Ziber's blockchain-telecom positioning.
• Vonage: Established VoIP and communications-platform-as-a-service provider serving consumers and enterprises with international calling. Represents the carrier-grade incumbent that Ziber's decentralized model attempts to undercut.

Emerging players

• Signal: Privacy-focused messaging app with high-quality voice calling. Competes for users prioritizing secure, free calling, a segment adjacent to Ziber's decentralized value proposition.
• Hushed: Provides second phone numbers and VoIP calling via mobile app, intersecting with Ziber's smartphone-proxy model and targeting similar users seeking low-cost international calling.
• Talkatone: Free VoIP calling app that provides US/Canadian phone numbers and routes calls over Wi-Fi/data, closely aligned with Ziber's mobile-first, low-cost calling approach.
• Magic (formerly Talk Home): International calling app targeting diaspora and high-cost corridors with low per-minute rates, directly overlapping with Ziber's stated value proposition of undercutting Skype and Viber on international calls.

Direct peers

• Viber (Rakuten): Direct VoIP competitor also used as a pricing benchmark by Ziber. Provides free in-app calls and low-cost international termination to mobile and landline numbers across the same corridors Ziber targets.
• Skype (Microsoft): The dominant VoIP and international calling service, explicitly named by Ziber as its primary pricing benchmark. Competes head-to-head on per-minute international call pricing and free in-app calling.

Others

• Discord: Voice-over-IP communications platform widely used for community and consumer voice chat. Adjacent infrastructure competitor in the IP-based voice space rather than direct PSTN termination peer.
