Blockchain Messaging Growth: Decentralization & Demand for Privacy

March 23, 2026 Dr. Michael Lee – Health Editor Health

The decentralized messaging protocol XMTP has secured $20 million in Series B funding, bringing the project’s network valuation to $750 million, according to a statement released Monday. The funding round was led by existing investors, with participation from new backers, signaling continued confidence in the growing Web3 communication space.

The investment comes as demand for secure, private communication channels increases globally, particularly in regions experiencing political instability and internet censorship. Reports indicate a surge in usage of decentralized, blockchain-based messaging and social media applications in 2025, coinciding with civil unrest and communication disruptions in the Middle East, Asia, and Africa. Exploding Topics reports a 145% growth in decentralized social media over the last five years.

XMTP, which stands for Extensible Message Transport Protocol, enables secure, end-to-end encrypted communication between blockchain addresses. Unlike traditional messaging apps, XMTP integrates directly with blockchain identities, such as wallet addresses, giving users ownership of their messages and leveraging open-source security. The protocol operates across multiple blockchain ecosystems, including Ethereum, Arbitrum, and Polygon, with plans to expand to non-EVM blockchains.

“I think people are starting to trust open protocols more than closed companies,” said Shane Mac, CEO of XMTP Labs. He added that the past 15 years have been defined by centralized platforms, but the next 15 will be decentralized. Mac pointed to Russia’s February decision to block WhatsApp as an example of the vulnerabilities inherent in centralized systems, highlighting the need for alternative infrastructure.

Decentralized networks, Mac explained, can offer a secure haven during times of unrest, as they are typically more difficult to shut down due to their distributed nature and lack of a single point of failure. These platforms are often hosted across networks connecting various countries, with servers maintained by their participants.

Market research firm 360 Reports predicted earlier this month that the blockchain messaging market will experience significant growth in the coming years, driven by increasing global demand for enhanced privacy and security in communication. XMTP has already facilitated nearly 1 million inboxes and over 300,000 direct messages since its launch in early 2022.

Despite the growing interest in decentralized messaging, Mac acknowledged that centralized platforms are likely to remain popular and coexist with decentralized alternatives. Ephemera, the core developer behind XMTP, intends to use the new funding to enhance scalability, optimize decentralization, and expand the protocol’s feature set.
