DAO to (Anonymous) DAO Transactions
Minfeng Qi, Lin Zhong, Qin Wang

TL;DR
The paper introduces o$^2$, a framework enabling secure, threshold-controlled DAO-to-DAO transactions with optional recipient anonymity, combining distributed key derivation, stealth-address generation, and threshold signatures.
Contribution
It formalizes DAO-to-DAO transactions and presents o$^2$, a novel system that supports organizational transfers with anonymity and distributed control, backed by security proofs and performance evaluation.
Findings
Prototype completes a typical DAO transfer in under 27 ms.
Communication overhead is less than 1.2 KB for a 7-member DAO.
System scales linearly with DAO size.
Abstract
Blockchain assets are increasingly controlled by organizations rather than individuals. DAO treasuries, consortium wallets, and custodial exchanges rely on threshold authorization and multi-party key management, yet existing payment mechanisms still target single-user wallets, leaving no unified solution for organizational transfers. We formalize the problem of \emph{DAO-to-(anonymous)-DAO} transactions and present \textsc{Dao}, a framework that enables one threshold-controlled organization to pay another, optionally with recipient anonymity, while keeping received funds under distributed control. \textsc{Dao} combines three components: \emph{distributed key derivation} (DKD) for non-stealth child addresses, \emph{distributed stealth-address generation} (DSAG) for unlinkable one-time destinations, and \emph{threshold signatures} for authorization. For ordinary transfers, the…
