Litecoin transactions are recorded in the Litecoin blockchain (a ledger held by most
clients). A new block is added to the blockchain roughly every 2.5 minutes (whenever
a small enough hash value is found for the proof-
The scrypt hash function used by Litecoin depends on fast access to large amounts
of memory per hash attempt, rather than depending just on fast arithmetic operations.
By using the input as a seed to fill a large amount of memory with a pseudorandom
sequence, and then using another seed derived from the input in order to access this
sequence at pseudorandom points while generating the output hash, the difficulty
to run many instances of scrypt in parallel by using the ALUs of a modern graphics
card increases greatly, compared to Bitcoin's GPU-
Since memory is the resource of general-
The scrypt parameters that Litecoin uses (N=1024, p=1, r=1) let users who run the
Since modern graphics cards have plenty of RAM, they do prove useful for Litecoin mining. You can also see the difference in mining difficulty by viewing Litecoin's mining hardware comparison and comparing it to Bitcoin's comparison page. Where a common GPU will mine Bitcoin in MH/s (megahashes), Litecoin is mined in kH/s (kilohashes).
