why is a transaction split up in so many parts?

[ehmdjii]

so i made a transaction of 40LTC:

but i do not understand why it has been split up into so many parts?

i know this is ltc and not btc, but i guess the technology is the same?

thanks!

Presumably LWPf3ztftYMsj8bwXNAbX6n2C22atvB7Eo is the address you use to withdraw from your mining pool. Each time that you receive a payment from the pool is a separate output, they are not combined automatically. They are only combined when you use some of them for a transaction, which is exactly what happens in the linked transaction - it combines several outputs into one bigger output.

thanks but this transaction is not related to mining or a mining pool.

it is just 40 LTC i have sent to another person at once using the official litecoinclient.

And where did you get these 40 LTC? Whether you got them from a mining pool or somewhere else, you got them in several separate payments. These payments need to be combined.

oh i see, thank you!

let's say i have many more LTC in my wallet than 40. how is it decided, which LTC are used for a transaction?

If Litecoin is similar to bitcoin, then it will come up with a combination of coins that causes the least amount of change.  Described here:
