+# eVRF DKG
+
+In 2024, the [eVRF paper](https://eprint.iacr.org/2024/397) was published to
+the IACR preprint server. Within it was a one-round unbiased DKG and a
+one-round unbiased threshold DKG. Unfortunately, both simply describe
+communication of the secret shares as 'Alice sends $s_b$ to Bob'. This causes,
+in practice, the need for an additional round of communication to occur where
+all participants confirm they received their secret shares.
+
+Within Serai, it was posited to use the same premises as the DDH eVRF itself to
+achieve a verifiable encryption scheme. This allows the secret shares to be
+posted to any 'bulletin board' (such as a blockchain) and for all observers to
+confirm:
+
+- A participant participated
+- The secret shares sent can be received by the intended recipient so long as
+  they can access the bulletin board
+
+Additionally, Serai desired a robust scheme (albeit with an biased key as the
+output, which is fine for our purposes). Accordingly, our implementation
+instantiates the threshold eVRF DKG from the eVRF paper, with our own proposal
+for verifiable encryption, with the caller allowed to decide the set of
+participants. They may:
+
+- Select everyone, collapsing to the non-threshold unbiased DKG from the eVRF
+  paper
+- Select a pre-determined set, collapsing to the threshold unbaised DKG from
+  the eVRF paper
+- Select a post-determined set (with any solution for the Common Subset
+  problem), allowing achieving a robust threshold biased DKG
+
+Note that the eVRF paper proposes using the eVRF to sample coefficients yet
+this is unnecessary when the resulting key will be biased. Any proof of
+knowledge for the coefficients, as necessary for their extraction within the
+security proofs, would be sufficient.
+
+MAGIC Grants contracted HashCloak to formalize Serai's proposal for a DKG and
+provide proofs for its security. This resulted in
+[this paper](<./Security Proofs.pdf>).
+
+Our implementation itself is then built on top of the audited
+[`generalized-bulletproofs`](https://github.com/kayabaNerve/monero-oxide/tree/generalized-bulletproofs/audits/crypto/generalized-bulletproofs)
+and
+[`generalized-bulletproofs-ec-gadgets`](https://github.com/monero-oxide/monero-oxide/tree/fcmp%2B%2B/audits/fcmps).
+
+Note we do not use the originally premised DDH eVRF yet the one premised on
+elliptic curve divisors, the methodology of which is commented on
+[here](https://github.com/monero-oxide/monero-oxide/tree/fcmp%2B%2B/audits/divisors).
+
+Our implementation itself is unaudited at this time however.

-# monero-serai
-
-A modern Monero transaction library intended for usage in wallets. It prides
-itself on accuracy, correctness, and removing common pit falls developers may
-face.
-
-monero-serai also offers the following features:
-
-- Featured Addresses
-- A FROST-based multisig orders of magnitude more performant than Monero's
-
-### Purpose and support
-
-monero-serai was written for Serai, a decentralized exchange aiming to support
-Monero. Despite this, monero-serai is intended to be a widely usable library,
-accurate to Monero. monero-serai guarantees the functionality needed for Serai,
-yet will not deprive functionality from other users.
-
-Various legacy transaction formats are not currently implemented, yet we are
-willing to add support for them. There aren't active development efforts around
-them however.
-
-### Caveats
-
-This library DOES attempt to do the following:
-
-- Create on-chain transactions identical to how wallet2 would (unless told not
-  to)
-- Not be detectable as monero-serai when scanning outputs
-- Not reveal spent outputs to the connected RPC node
-
-This library DOES NOT attempt to do the following:
-
-- Have identical RPC behavior when creating transactions
-- Be a wallet
-
-This means that monero-serai shouldn't be fingerprintable on-chain. It also
-shouldn't be fingerprintable if a targeted attack occurs to detect if the
-receiving wallet is monero-serai or wallet2. It also should be generally safe
-for usage with remote nodes.
-
-It won't hide from remote nodes it's monero-serai however, potentially
-allowing a remote node to profile you. The implications of this are left to the
-user to consider.
-
-It also won't act as a wallet, just as a transaction library. wallet2 has
-several *non-transaction-level* policies, such as always attempting to use two
-inputs to create transactions. These are considered out of scope to
-monero-serai.
