CryptoPayment is a MediaWiki extension to limit spam by requiring a small one-time crypto-currency payment before the user is allowed to edit or create pages. CryptoPayment is based on BitcoinPayment extension used by Bitcoin Wiki.
While the payment is deliberately small for a normal user, it presents a barrier to a mass-spammer.
Funds collected via this system will be used to support the Litecoin Association (mainly to cover server costs).
In order to enable your user account to edit pages, login in and visit the Special:CryptoPayment page.
You will be given an address to which you will have to send a small amount of Litecoin.
Once your payment is confirmed, you account will be automatically added to the trusted group which will grant you edit privileges.
You can also confirm your account's editing privileges by visiting the Special:CryptoPayment page.
