BitVM has recently come under some scrutiny after the Taproot Wizards, Tyler and Rijndael, posted their criticism of the liquidity requirements imposed on the operator of a BitVM based two-way peg. In all the recent discussions around BitVM based layer two solutions, I had taken for granted that people discussing them and interested in the design space understood the collateralization/liquidity requirements imposed by the architecture on the operator(s). The recent discussion around the “liquidity crunch” issue shows me I was incorrect about this assumption, and that many people outside of those actively involved in BitVM development were not aware of this issue.
