Topcoin ("TPC") is the world’s only crypto-currency designed specifically for digital goods loyalty programs. Consumers are rewarded TPC for domain name purchases made at partner companies in the TPC ecosystem, and those companies in turn accept up to half the purchase price of new domain name registrations in Topcoin at a value of $1 per TPC. The closest "real-world" analogy to TPC is frequent flyer miles, except that TPC may be used across a broad range of product classes and are easily exchanged for other currencies.

Technically speaking, Topcoin is a "Counterparty user-defined asset", and as such is backed by the Bitcoin blockchain and managed via the Counterparty Open Source Protocol. Topcoin addresses look exactly like Bitcoin addresses, and work the same way. Just like BTC, “TPC” has a fixed supply, is digital, fungible, anonymous, and cannot be counterfeited.

Three billion (3,000,000,000) Topcoin were issued as a divisible (up to 8 decimal places, like bitcoin) and locked (no more may ever be created) asset on September 22nd, 2014. Topcoin may not be recalled by the issuer.

2. 1,500,000,000 will be distributed to expand the TPC ecosystem.
3. 1,000,000,000 will be held by Topcoin, LLC for future use.
