Summary

Update current OP_RECOVER operation in order to have a similar sense as described on Original PascalCoin WhitePaper published on July 2016 few weeks before Genesis Block and also a community poll made on discord channel

Motivation

OP_RECOVER feature was defined on original PascalCoin Whitepaper published on July 2016 as a way to allow recover coins that has lost private key.

PascalCoin WhitePaper:

PascalCoin proposes an alternative to the basic operation of Bitcoin, through which change
several aspects for working on the new virtual currency:
...
  - PascalCoin provides a method set by protocol to retrieve coins that are not used
    instead (lost key). This method only applies if after a certain time the owner does not
    make any operation with the account private key.
...
(Page 2/8)

Basically was a way to mantain a constant and predectible usage of inflation and available coin because burning coins are not possible.

Current problem is that WhitePaper definition is ambiguous and certain time was not specified, initial source code proposal was to set a time value = 4 years (420480 blocks in PascalCoin)

Another problem is that WhitePaper was mixing coins (PASC) and accounts (PASA), because what is necessary in PascalCoin is an Account (aka PASA), so we can focus on recover PASA instead of recover coins inside PASA

Proposal

This PIP specifies a more accurated OP_RECOVER that was discussed on Discord Channel
