"Don't send to 1BitcoinEaterAddressDontSendf59kuE. These coins are lost."

One day computers will be able to hash the privatekey for this address or for addresses with no access to it. Therefore coins should be removed after mining from the coinbase address to show that someone has access to it. Otherwise they are shalecoins waiting to be "remined" or "fracked" one day.

My biggest question this is. Really we can't? Even if this is not possible in today's technology, what will be the future? I think there should be some progress on this issue.

The idea behind declaring coins as "shalecoin" is to indicate whether an address has an holder or not and therefore to have an open and clean blockchain. (Concerning longterm UTXO)

- As mentioned before -
Definition of "shalecoin":
Coins with no access to the address. (Nobody has the privatekey)
If that address is a coinbase address: 1 year after mining
Other addresses: 10 years after last output transaction

Longterm holders of coins should transfer their coins to a new address within 10 years, so they wouldn't become shalecoins. All other coins with no access to the address can't be transacted to a new address and will become shalecoins after 10 years or after 1 year if it's a coinbase address. Owners of possible computers with the ability to "hash" the privatekey would use these computers only for shalecoins. (Coins with no holder)

Shalecoin 'fracking' is the next challenge.
