Litecoin is a Bitcoin like P2P currency that is expected to produce 84 million LTCs, which is more than four times the total currency of Bitcoin. Dealing with transactions through the Scrypt Workload Proof Scheme, the development of FPGAs (Programmable Logic Gate Arrays) and ASICs (Application Specific Integrated Circuits) for the Scrypt algorithm is more expensive than the use of sha256 for Bitcoin.
