The amount of "dust" in the block chain is getting large and it is growing all the time. Currently 11% of unspent tx outputs (UTXO) are of 1Satoshi (0.00000001BTC), 32% is less than 0.0001BTC and 60% is less than 0.001BTC. (Thanks to Jan for digging out these numbers!)
This means that a huge part of the block chain is used for essentially nothing - e.g. the sum of the 11% is worth roughly 2 US cents !
The main source for these 1 Satoshi payouts is Sahtoshi Dice. And nothing wrong with that, however, we should work on ensuring that too many too small payments will not kill the size of the blockchain in the end - further, they are essentially too small to be included in other transaction as the added fee will often make it more expensive to remove them. Hence, there is no incentive to get rid of them.
I have an idea for a possible mitigation of this problem - introduction of demurrage - not as in it normal meaning as a percentage over time (see:http://en.wikipedia.org/wiki/Demurrage_(currency) btw, this has also been tried in freicoin), but as a mean to recycle pennies over time. The proposal is simple - UTXOs age out if not re-transacted - the smaller the coin the faster the aging:
1-99 Satoshi: lives for 210 blocks
100-9999 Satoshi: lives for 2100 blocks
10000-999999 Satoshi: lives for 21000 blocks
1000000-99999999 Satoshi: lives for 210000 blocks
Only amounts above 1BTC lives forever - (or we could even impose aging on those too..)
The aged coins are simply included in the block mining reward, creating another incentive for miners. Further, if we include all coins in this recycle scheme coins will never be lost forever.
This scheme will impose some lifetimes also on e.g. colored coins (hence you need to use a certain amount to borrow space on the blockchain for the time needed, or simply transact them).
If you like this I would be happy to write it into a BIP.
Thoughts ?
