Developer Question

Honestly, I actually didn't know where to post this so Admin if I'm in the wrong place please move me.

When Forking Bitcoin / Other Alt coins would it be possible to Orphan certain blocks to reclaim the coins that could be lost or locked away such as wallets that have been inactive for 6+ years by causing invalidating the blocks and causing them to be removed by let's say a mini chain-split? I think this is possible personally but I've actually never seen it done before.

That's not necessary. If you are forking a coin, you can change the rules to whatever you want. You just change the block and transaction validation code to enforce the new rules.

I think these rules will do what you want. They recycle coins that haven't been spent for 4 years (and limits the size of the UTXO set):

1. A miner constructing a block at height H may add to their block reward the values of any UTXOs in block H - 210000.
2. UTXOs that are 210000 or more blocks old may not be spent.
