Re: Blockchain.info - Bitcoin Block explorer & Currency Statistics
I'm not sure it's *the* worst way. Look at the Mitt Romney extorters address which someone sent 30 transactions just to try embed an imgur link (http://blockchain.info/address/1HeF89wMjC48bWNgWvVo7Wu3RaLW8XVsE8).
Point taken...One way to do it could be to use an M-Of-N 1 of 2 multi-signature transaction and have the 2nd public key as the message. The tx would then still be spendable with the first public key, but not many clients would be able to redeem it. I'm open to suggestions?
That is certainly an option, but, in general, stuffing data in a pubkey is not very good. It would be very nice to avoid putting messages in the chain period. If you really have to, it would be nice to stuff the message in the scriptSig instead of the scriptPubKey, as that can always be pruned.That said, I'd say the best would be to use OP_DROP and convince a miner to mine your txes for you, which would give your users lower fees (Ive heard mining contracts at Eligius are cheap
).
