Open coastal data, verified in public
TideMark hashes public sea-level readings on-chain and puts a global community of verifiers on watch — so no single feed's word is the only word.
Start VerifyingPublic sea-level feeds are scattered across dozens of formats and agencies. TideMark's indexer pulls them into one place, timestamps every reading, and hashes it on-chain the instant it lands — permanent, checkable, tamper-evident.
Anyone can stake TMRK to confirm a reading or flag an anomaly. Calls that match consensus earn a share of a fixed, transparent reward pool. It's a global watch team for coastal data, open to anyone with a connection and a stake.
Holding TMRK means you can submit verification jobs, dispute flagged readings, and get paid when your calls hold up. It's the credential that keeps the whole verification market running — no gatekeepers, no middlemen.
From coastal engineers to island-nation residents, the dashboard, anomaly log, and methodology are public and downloadable. Interface strings are built for translation, opening the door to Spanish, French, Bahasa Indonesia, and Japanese.
Every hash, timestamp, and verification call is on the record. Download the anomaly log, compare it to the source feed, and judge the data on its own evidence.
The token
The token is solely a utility credential required to submit or dispute a data-verification job and to receive a share of a fixed, transparent task-reward pool; it carries no equity, governance, or revenue rights.
Questions
TideMark takes public tide-gauge and sea-level readings, timestamps and hashes them on-chain, and opens the door for a global community to verify or flag anomalies — turning fragmented coastal data into one auditable feed anyone can check.
TMRK is the access credential for the verification market. You need it to submit a verification job or file a dispute on a flagged reading, and verifiers whose calls match consensus draw their share of a fixed task-reward pool paid in TMRK.
The indexer pulls from public tide-gauge and sea-level station feeds already published by national hydrographic offices and intergovernmental ocean-monitoring networks — open data sources, made checkable and permanent.
Coastal engineers, climate researchers, open-data builders, NGOs, and residents of coastal and island nations who want a fast, independent cross-check on the tide data that shapes flood planning and coastal safety decisions.
No. The dashboard presents each reading in plain view alongside its hash and timestamp, so anyone can compare it against the source feed, stake TMRK, and submit a confirm or flag call in a few clicks.
Yes. The anomaly log is downloadable and the full hashing and verification methodology is published for independent review, so every call made on the network is checkable by anyone, anywhere.
