Unspendable Scripts (No-one-Can-Spend)

Back to Examples

On the other end of the spectrum from anyone-can-spend.md, we have scripts that always evaluate to false, making the associated boxes permanently unspendable.

Here's an example of such a script:

true && false

This script maps to the address 2fp75qcgMrTNR2vuLhiJYQtKb1RoSw5H1U7tMKestmzrA2SzfYM1. Any funds sent to this address will be permanently locked and unspendable.

However, in Ergo's system, such boxes may eventually be removed from the UTXO set through a process called "storage rent" or "garbage collection." This mechanism prevents the blockchain from being cluttered with unspendable boxes.
