The encrypted messaging space is crowded. Signal, Telegram, WhatsApp, XMTP, Status, and now SendBloc all claim to protect your privacy. But the reality is nuanced.
This isn't a marketing piece disguised as a comparison. We'll be honest about where our competitors excel and where SendBloc has room to grow. You deserve to make an informed choice.

Let's be real: Signal has advantages.
Voice and video calls are mature and reliable. Their mobile apps are polished and battle-tested. The user base is large enough that your contacts are likely already there. The Signal Protocol is the gold standard for encrypted messaging and has been independently audited multiple times.
For mainstream users who want better privacy than WhatsApp, Signal is an excellent choice.
Telegram excels at scale. Groups can hold up to 200,000 members. File sharing supports up to 2 GB. The bot ecosystem is rich. Channels enable one-to-many broadcasting.
For public communities and content distribution, Telegram's features are unmatched.
We're early. Here's what we don't have yet:
No voice or video calls (targeting Q4 2026). No native mobile app (targeting Q3 2026). Smaller file size limits (10 MB vs. Signal's 100 MB). No mainstream user base yet. The UX, while polished, requires understanding wallet concepts.
We're building in public and shipping fast, but we're not pretending to be feature-complete.
Use Signal if: You want a drop-in WhatsApp replacement with strong encryption and you don't mind sharing your phone number.
Use Telegram if: You need large public communities, bots, and channels and encryption isn't your primary concern.
Use SendBloc if: You need true pseudonymous communication, you operate a DAO or crypto organization, you're a journalist or activist needing identity protection, or you simply believe your identity shouldn't be a phone number.
The right choice depends on your threat model. We respect all three we just believe the future is wallet-native.
Privacy isn't binary. It's a spectrum, and different tools occupy different points on that spectrum.
Signal moved the mainstream toward encrypted messaging. Telegram built the infrastructure for large-scale crypto communication. SendBloc is building the next step: communication where your identity is truly yours.
