Please please PLEASE do not do this. You would be burdening every other node from now until the heat death of the universe.

I don't think it's a huge problem. You have to spend BTC to get your message saved.

As Dan Kaminsky once said (after using this technique to create a blockchain memorial for Len Sassaman[1]), "This is the cyber-equivalent of pouring one out for your homies."

The coin you may or may not spend does not go to the people who incur the cost.

The spent coin goes to nobody - it is burned into the blockchain as a transaction output that can never be spent, and cannot be pruned.

Surely that means it effectively does go to the people who incur the cost? Burning some coins increases scarcity, thus increasing the value of all other coins, so it's effectively a donation to everyone who holds bitcoin?

I assumed he was talking about fees. You could make the output zero-valued.

Wouldn't a zero-value output trip the anti-dust rules?

Those aren't consensus rules. They are recommended policy.

Well, then that's a flaw in Bitcoin.

Agreed. Now that the "get rich quick" phase of mining is over, there aren't many incentives for all the costs incurred.

Isn't that the reasoning behind transaction fees?

Transaction fees are for miners, but every full node in the network has to store the whole blockchain forever. There are thin clients using SPV, but we need full nodes for the network to function properly and currently there is zero incentive for it.

Aside from helping the network, there is no incentive to run a full Bitcoin node. But it doesn't take much in the way of resources: a few tens of gigabytes of disk space and a few tens of kilobits/sec of bandwidth. (Don't forget to open a port on your router!) I do it for the same reason I give over an extra SSID to openwireless.org, or run a TOR exit node, or seed any file I got from BitTorrent for a while afterwards: it helps the network.

This comment seems to simultaneously assume that Bitcoin will last forever and that Bitcoin can be seriously harmed by a few individuals. These two ideas seem to me to be fundamentally incompatible.

>seriously harmed by a few individuals.

It's not serious, but it's harm.

The way the comment is written makes it sound serious. If it's not serious then who cares?

> If it's not serious then who cares?

I care when a mosquito bites me. I also care when people pollute the blockchain.
