Embedding messages in transactions

[stamen123]

Hi,

Can you help me with a question. As most know, Bitcoin's protocol supports embedding an 80 byte-long message per transaction - https://github.com/bitcoin/bitcoin/pull/2738

I downloaded the QT client of Litecoin and Primecoin - both look the same and there is no field for embedding a message. I asked in litecoin's forum but no one can answer me.

Does someone here maybe know if the alt currencies support such a feature or they need to develop it yet. I only know that Nextcoin does too.

Thanks

If you are talking about data storage, Datacoin can store up to 128k per block & Siriuscoin can store up to 512k per block.

If you are talking about comment field in "sendto", Siriuscoin do have it.

Most alt coins do not have it as most was forked from Litecoin or old alt coins.

Thanks simbo, very helpful indeed!
This is such a shame...  how do you store transaction data outside the blockchain in a provably fair manner, as this can be done in the blockchain itself?

I guess a major redevelopment of Bitcoin or a Bitcoin2 will be developed to include these features. But what would be the benefit or purpose of being able to include a message in the transaction?
