Your account
You sign in with Google or a MetaMask wallet and are responsible for keeping that access secure. If you sign in only with a wallet and lose its recovery phrase, nobody can restore your account.
Coins
Coins are prepaid credit used only on ChainLMS. 1 coin equals 1 USD. Top-ups are reviewed manually, normally within 24 hours of your transfer.
Purchases and licenses
Buying a course grants you a personal, non-transferable license to access it.
Creators
You must own or have the rights to everything you publish. Publishing records a permanent fingerprint of your content and your wallet address on the ledger.
Blockchain records
Records on the ledger cannot be deleted. Certificates can be revoked, and the revocation is itself recorded.
Availability
The service may be interrupted for maintenance or incidents. Purchases are refused when the network cannot record them safely.
