In this paper, we present the first intrinsically secure and semantically universal omnichain interoperability protocol: LayerZero. Utilizing an immutable endpoint, append-only ver…
ColorTrace: Fungible token coloring and attribution
Ryan Zarick, Bryan Pellegrino, Isaac Zhang +2
We formally define the fungible token coloring problem of attributing (coloring) fungible tokens to originating entities (minters), and present, to our knowledge, the first practic…
ColorFloat: Constant space token coloring
Ryan Zarick, Bryan Pellegrino, Isaac Zhang +2
We present ColorFloat, a family of O(1) space complexity algorithms that solve the problem of attributing (coloring) fungible tokens to the entity that minted them (minter). Taggin…
