VeriCal
Attested Calendar
"Every meeting, provable."
What it does
VeriCal turns scheduling into a verifiable on-chain record. Owners publish their availability as slots, guests book them, and every step of a booking's life — created, confirmed, completed, or cancelled — is written to the AEREDIUM chain as a cryptographic attestation.
There is no private database to trust and no record that can be quietly altered after the fact. Access and cancellation rules are set by configurable policies, a reputation ledger keeps an honest tally of completions and no-shows, and time-locked guards handle expiry automatically. Users can interact gaslessly through meta-transactions, so the experience feels familiar while the guarantees are anything but.
What to expect
- Bookings you can verify yourself on the public explorer, independent of any operator.
- Policy-based control over who can book, how details are revealed, and how cancellations are handled.
- A portable reputation that travels with the wallet rather than being locked inside one platform.
- No-show and expiry handling enforced on-chain by time-locked guards, not by an administrator.
- A smooth experience: gasless meta-transactions, full EVM compatibility, and roughly two-second finality.
Who it's for
VeriCal is built for anyone whose calendar is a matter of public trust — where proving that a meeting happened, and when, matters as much as the meeting itself. The record is open, so transparency stops being a promise and becomes something anyone can check.
Every meeting you take becomes part of a tamper-proof public record. Constituents, journalists and oversight bodies can confirm who you met and when, without taking your office's word for it — accountability you can point to rather than assert.
Your engagements are provable. An interview, an appearance or a commitment is logged on-chain the moment it is confirmed, leaving a clear, verifiable trail of what was agreed and honoured.
No more disputes over whether a slot was offered, confirmed or kept. Each step is attested, and the reputation that builds from honoured bookings travels with the wallet — which matters when trust between strangers is the whole transaction.
Governments and public bodies can run their schedules in the open. Meetings are recorded as on-chain attestations, giving an auditable register of public business that no one can quietly edit after the fact.
