Protocol layer: "Ark: An L2 Protocol for Off-chain Bitcoin Transactions" (Burak Keceli, 2023) -- introduced virtual UTXOs and the Ark covenant model. Structural contribution to non-custodial, non-interactive off-chain transfers that is underrated outside the core dev community.
Applied cryptography: The BitVM series (Robin Linus, 2023-2024) -- demonstrated optimistic execution of arbitrary computation on Bitcoin without a soft fork. Whether the fraud-proof approach is practical or not, the paper changed what the protocol community thinks is possible.
UX/standards: BOLT 12 Offers spec (Rusty Russell et al.) -- foundational for static payment codes, recurring payments, and blind routing. Enabled a class of UX improvements that BOLT 11 could not support structurally.
All three influenced active protocol work in 2024-2025, which seems like the right bar for "impact on Bitcoin or Lightning published after 2022."
