CLAM is a form of digital value or currency that is transferred, created and verified through the concerted efforts of computers running CLAM software. Similar to Bitcoin, the original technology from which CLAM was created, the network follows a strict protocol to ensure consensus and verification are maintained.

Project Technology

CLAM is a new digital currency with an innovative payment network. CLAM uses proof-of-stake and blockchain technology that processes transactions and issues CLAM based on a user's address history on the Bitcoin, Litecoin, and Dogecoin networks. Bitcoin is the world's first encrypted currency, which is implemented by a new software technology called "blockchain". The software is open source; free and available to anyone who wishes to build upon it. Many did so, creating thousands of new cryptocurrencies like Bitcoin. People like you may run CLAM wallet software around the world, forming a massive decentralized payment network. As more and more people join the network, the CLAM network becomes stronger and more secure. The combined computing power of the CLAMS network is used to efficiently maintain the blockchain in which all CLAMS transactions are processed. Unlike traditional centralized banking institutions, there are no middlemen.
