  bibo_abstract:
  - We present a novel approach for blockchain asset owners to reclaim their funds
    in case of accidental private-key loss or transfer to a mistyped address. Our
    solution can be deployed upon failure or absence of proactively implemented backup
    mechanisms, such as secret sharing and cold storage. The main advantages against
    previous proposals is it does not require any prior action from users and works
    with both single-key and multi-sig accounts. We achieve this by a 3-phase   Commit()→Reveal()→Claim()−or−Challenge()  smart
    contract that enables accessing funds of addresses for which the spending key
    is not available. We provide an analysis of the threat and incentive models and
    formalize the concept of reactive KEy-Loss Protection (KELP).@eng
