Tor-routed. Anonymous. Post-quantum.
Blockd is an anonymous, end-to-end encrypted messaging app that routes over Tor. No phone number. No email. No KYC. Post-quantum encryption is on by default. Don’t trust us. We built Blockd so you don’t have to.
Most messengers protect message content with encryption and stop there. The real exposure is metadata: who you talk to, when, how often, from what location, and from what device. Metadata is the map of your life, and most apps leak it by design.
Contact graphs and timing reveal your relationships and routines, even when the words are sealed.
Your IP address ties every conversation to a network location, a city, sometimes a building.
A phone number links it all back to a SIM, a carrier, and usually your real name.
Tor is a global network that relays your connection through multiple independent hops before it reaches its destination. No single hop sees both who you are and what you are doing. With Tor on, your traffic reaches Blockd through the Tor network, so we see a Tor exit node, not your IP address. Your network location stays separate from your account.
Your traffic enters the Tor network and is relayed across multiple independent nodes.
What reaches Blockd is a Tor exit node, not your IP. Your location is decoupled from your messages.
No phone number or email ties the connection back to you. Identity and location stay separate.
Most messengers ask you to trust a company. Blockd is built on a ladder that lets you decide how much trust to extend, all the way down to none.
Anonymous accounts, post-quantum end-to-end encryption, and metadata minimization out of the box. You trust us.
Route over Tor so your network location is decoupled from your account. You trust the architecture, not the company.
Peer-to-peer communication on hardware you own, bypassing company servers. You don’t have to trust anyone.
Signal, WhatsApp, and Telegram all require a phone number to register. WhatsApp and Signal are built on the Signal protocol, one shared codebase across a whole ecosystem of apps. Telegram does not encrypt cloud chats end-to-end by default. Blockd takes a different path: no phone number, an independent protocol with no shared dependencies, post-quantum encryption by default, and Tor routing built in.
A side-by-side look at identity, encryption, and network privacy.

Your Blockd identity is a cryptographic identifier you control, not a name, a number, or an inbox. Anonymous accounts are the default, not a setting you have to find and switch on.
More on anonymous messagingCreate an account with no phone number and no email. There is no SIM, no carrier, and no real-world identity attached to your conversations.
Messaging without a phone numberBlinded routing keeps the network from mapping your social graph: who you talk to, when, and how often. Automatic metadata stripping removes location, device, and timestamp data from the images you share.
What makes a messenger privateIf you respect Signal but want to drop the phone number requirement, move to an independent protocol, and get post-quantum encryption by default, Blockd is built for you.
Compare Blockd and SignalA Tor messenger routes your traffic through the Tor network before it reaches the service you are talking to. With Tor on, your traffic reaches Blockd through the Tor network, so we see a Tor exit node, not your IP address. That separates the content of your messages from the network location they came from.
Blockd accounts are anonymous by default. There is no phone number, no email, and no KYC. You are identified by a cryptographic identifier you control, not by a real-world identity tied to a SIM card or an inbox. You can also route over Tor so your network location is decoupled from your account.
Yes. Blockd does not require a phone number or an email to create an account. Most mainstream messengers tie your identity to a phone number, which links your conversations to a SIM, a carrier, and often a real name. Blockd removes that link entirely.
Yes. Every message, voice call, and video call is end-to-end encrypted by default, so only the people in the conversation can read it. Blockd uses post-quantum encryption (a hybrid of X25519 and ML-KEM) that is designed to resist attacks from future quantum computers, and it is on by default for everyone.
Signal is respected software, but it requires a phone number to register and it is built on the Signal protocol that powers WhatsApp and many other apps, which is one shared attack surface across that whole ecosystem. Blockd needs no phone number, is built on an independent protocol with no shared code or dependencies, ships post-quantum encryption by default, and routes over Tor so your network location stays separate from your account.
You choose. Storage is opt-in. You can sync to Blockd’s cloud for convenience across devices, or keep your messages on your device for maximum control. The choice is always yours.
Yes. The Blockd app is free to download, and Blockd Pro, which includes Tor routing and automatic metadata stripping, is free for everyone through December 31, 2026, with no code required.
Metadata is the data about your messages rather than the messages themselves: who you talk to, when, how often, from what location, and from what device. Encryption hides what you say. It does not hide these patterns. Metadata alone can reveal your relationships, routines, and identity, which is why minimizing it is central to how Blockd is built.
Anonymous, Tor-routed, post-quantum encrypted messaging. Free to download, with Blockd Pro free for everyone through the end of 2026.
