Vitalik Just Donated 128 ETH to Session – Here is Why Metadata Privacy, Permissionless Design Are Important

Ethereum co-founder Vitalik Buterin has donated 128 ETH (nearly $390,000) to Session, a privacy-focused encrypted messaging app, on Thursday.

Buterin wrote to his 5.8 million followers on X that he donated to two projects “pushing forward” permissionless account creation and metadata privacy in encrypted messaging.

“Encrypted messaging is critical for preserving our digital privacy.”

Session Technology Foundation President Alex Linton speaks about why Vitalik specifically highlighted metadata privacy and permissionless design.

In an exclusive conversation with Cryptonews, he highlights how Session’s decentralized architecture sidesteps Signal’s phone number dependency.

Advancing Privacy Beyond Encryption

Buterin highlighted that strong metadata privacy “requires decentralization,” which is hard. Besides, users expecting multi-device support make everything harder, he noted.

While messaging apps like Signal pioneered end-to-end encrypted messaging, and now e2ee, when it comes to private communications, there are still more that platforms can do to protect user privacy, Linton explains.

A centralized approval is required while creating an account on a messaging apps, revealing personal identifiers such as phone numbers or emails, which can put user privacy at risk.

“It also introduces the possibility of censorship,” Linton told Cryptonews.

Session achieves this by generating cryptographically secure Account IDs instead of relying on traditional identifiers, enabling truly anonymous, permissionless sign-ups.

Though this makes onboarding easier, the main drawback is the lack of importing contacts or messages using people’s phone numbers.

Combating Spam and Sybil Attacks

One challenge mentioned by Vitalik Buterin is Sybil attack resistance – preventing fake or spam accounts while remaining permissionless and decentralized.

Session leverages a tokenomic system that secures its network nodes with Session Tokens to incentivize, protect node operators, Linton explains.

At the individual level, Session benefits from having limited contact discovery, he added.

Further, Session also supports accessing an account from multiple devices using a recovery password, similar to a crypto wallet.

Resisting Surveillance and Legal Pressures

Vitalik’s donation follows weeks of debate over Europe’s Chat Control legislation and growing concerns about encrypted messaging vulnerabilities.

Alex Linton said that the Chat Control is of “dire concern” for everyone working on end-to-end encrypted and private communications. He called it a “dangerous proposal” that threatens rights and freedoms.

Linton said that Session is deliberately designed so that no entity, including the supporting Session Technology Foundation, controls the network or can surveil users.

Despite these protections, we are still under threat from AI integrations, he added. “For example, operating system-level AI integrations, such as what is currently being rolled out in Windows, may be able to completely circumvent application-level secure technologies.”
