Quotes that support claims

The Ethereum community has launched a blockchain “time capsule” project to celebrate the network’s 10th anniversary, allowing users to encrypt and store memories for $2.50 in ETH until its 11th anniversary.

On July 30, 2026, the capsules will automatically unlock and reveal a collective snapshot of Ethereum’s global community at this historic juncture.

Each submission costs just $2.50 in ETH, and all proceeds will be donated to the Protocol Guild, a collective funding core Ethereum contributors and researchers.
