# Design Properties **Non-Interactivity**: The communication round for exchanging signatures is non-interactive, given the independent signature requirements of P2WSH. This also ensures that the signatures aren't aggregated on a single server. **Accountability**: P2WSH is chosen to keep signatories accountable for liveness. If they fail to sign, they get slashed for their bond or eventually get jailed. **Delayed Withdrawal**: If a client owns 4% of the total reserve supply (Eg. $40M in a $1B reserve), then intuitively, it would take \~4 bitcoin blocks to unlock and process the 100% value of withdrawal request, given the funds are locked in consecutive fragments. **Bitcoin Data Availability**: Twilight ensures that the refund transaction is always available for an exit on bitcoin network using inscriptions. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.twilight.org/boomerang/design-properties.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
