/* The cookie data structure is implemented based on the WireGuard protocol.
* The ip and port is based purely on the public key and the implementation of the private cookie key is intended to mirror the biscuit key.
* The code tests the response to a possible DOS attack by setting up alternative branches for the protocol
* processes: Oinit_conf, Oinit_hello and resp_hello to simulate what happens when the responder or initiator is overloaded.
* When under heavy load a valid cookie is required. When such a cookie is not present a cookie message is sent as a response.

“Key Encapsulation Mechanism” (KEM) is the name of an interface widely used in post-quantum-secure protocols. KEMs can be seen as asymmetric encryption specifically for symmetric keys. Rosenpass uses two different KEMs. SKEM is the key encapsulation mechanism used with the static keypairs in Rosenpass. The public keys of these keypairs are not transmitted over the wire during the protocol. We use Classic McEliece 460896 [@mceliece] which claims to be as hard to break as 192-bit AES. As one of the oldest post-quantum-secure KEMs, it enjoys wide trust among cryptographers, but it has not been chosen for standardization by NIST. Its ciphertexts and private keys are small (188 bytes and 13568 bytes), and its public keys are large (524160 bytes). This fits our use case: public keys are exchanged out-of-band, and only the small ciphertexts have to be transmitted during the handshake.

## Variables {#variables}
## Protocol Roles {#roles}
The protocol specifies two roles: initiator and responder.
* initiator – The party that starts a handshake.
* responder – The party that does not start a handshake.
All Rosenpass instances operate in either mode; the traditional "client"/"server" distinction does not apply to the Rosenpass protocol. We sometimes use the term "server". In these cases, we generally refer to the "Rosenpass Server," as in the application that implements the Rosenpass protocol, not to a server/client distinction.
The initiator is stateful, and directs the handshake process. The responder is stateless for most of the protocol and reacts to the initiator's messages; this is important to protect our protocol against state disruption (protocol level denial of service) attacks. Since the responder does require some state to complete the protocol, this state is moved into an encrypted cookie, called "biscuit".
The number of concurrent responder-role handshakes with another client is unlimited to account for the possibility of an imposter trying to execute a handshake: before completion of said handshake, there is no way to figure out which peer is an imposter and which peer is a legitimate party; any attempt to do so might lead to a state-disruption attack -- denial of service on the protocol level.
There is no particular mechanism to negotiate which party acts as initiator and which acts as responder. At startup and when a key exchange is timer-triggered, Rosenpass will *initiate* a key exchange in initiator mode. At startup of another peer, and when they start a timer-triggered key exchange, the local server will *respond* in responder mode.
Implementations must account for one ongoing initiator-role key exchange and many ongoing responder-role key exchanges. Upon receiving a well-formed InitConf package and successfully completing a responder-role key exchange, implementations should abort any ongoing initiator-role key exchange. Implementations should also use different back-off periods depending on whether the handshake was completed in initiator role or in responder role. The following values are used in the Rust reference implementation:
- Initiator rekey interval: 130s
- Responder rekey interval: 120s
In practice these delays cause participants to take turns acting as initiator and acting as responder, since the ten-second difference is usually enough for the handshake with switched roles to complete before the old initiator's rekey timer goes to zero.
## Packages {#packages}
The packages, their contents, and their type IDs are graphically represented in Fig. \ref{img:MessageTypes}. Their purposes are:
* \textbf{Envelope} – This is not a package on its own; it is the envelope all the other packages are put into.
* \textbf{InitHello} – First package of the handshake, from initiator to responder.
* \textbf{RespHello} – Second package of the handshake, from responder to initiator.
* \textbf{InitConf} – Third package of the handshake, from initiator to responder.
* \textbf{EmptyData} – Empty payload package. Used as acknowledgment to abort data retransmission (see Secs. \ref{payload-keys}, \ref{packet-loss}, and function `enter_live()` in Sec. \ref{fn:enter_live}).
* \textbf{Data} – Transmission of actual payload data is not used in Rosenpass, but the package is still specified since it is part of WireGuard (see Sec. \ref{payload-keys} and function `enter_live()` in Sec. \ref{fn:enter_live}).
* \textbf{CookieReply} – Used for proof-of-IP-ownership-based denial-of-service mitigation (see Sec. \ref{dos-mitigation}).
* \textbf{biscuit} – This is not a stand-alone package; instead, it is an encrypted fragment present in \textbf{RespHello} and \textbf{InitConf}.

These values use a naming scheme consisting of four lower-case characters. The first character indicates whether the key is static `s` or ephemeral `e`. The second character is an `s` or a `p` for secret or public. The third character is always a `k`. The fourth and final character is an `i`, `r`, `m`, or `t`, for `initiator`, `responder`, `mine`, or `theirs`. The initiator's static public key for instance is `spki`. During execution of the protocol, three KEM ciphertexts are produced: `scti`, `sctr`, and `ecti`.
Besides the initiator and responder roles, we define the roles `mine` and `theirs` (`m`/`t`). These are sometimes used in the code when the assignment to initiator or responder roles is flexible. As an example, “this server's” static secret key is `sskm`, and the peer's public key is `spkt`.

The protocol allows for multiple `osk`s to be generated; each of these keys is labeled with a domain separator to make sure different key usages are always given separate keys. The domain separator for using Rosenpass and WireGuard together is a token generated using the domain separator sequence `["rosenpass.eu", "wireguard psk"]` (see Fig. \ref{img:HashingTree}), as described in \ref{protocol-extension-wireguard-psk}. Third-parties using Rosenpass-keys for other purposes are asked to define their own protocol-extensions. Standard protocol extensions are described in \ref{protocol-extensions}.
#### Symmetric Keys and Nonces for payload data transmission {#payload-keys}
Keys generated by the Rosenpass key exchange could be used for encryption of payload data if post-quantum security but not hybrid post-quantum security is a goal. Despite this, we do not generally offer payload transmission in the protocol. Instead, the Rosenpass protocol focuses on providing a key exchange, letting external applications handle data transmission. When used with WireGuard, the default use case, this integration also ensures hybrid security.
Still we specify the `Data` and `EmptyData` packets. `Data` is not used, but we still specify it as the same packet is also present in WireGuard. `EmptyData` is used for packet retransmission (see Sec. \ref{packet-loss}).
We also specify how symmetric keys are generated for payload encryption. See Sec. {#live-session-state} and the function `enter_live()` (Sec. \ref{fn:enter_live}).
Keys and nonces for this purpose use the following naming scheme:
\begin{namepartpicture}
\namepart{tx=Transmission,rx=Reception}
\namepart[3.5cm]{k=Key,n=Nonce}
\namepart[7cm]{i=Initiator,r=Responder,m=Mine,t=Theirs}
\begin{scope}[decoration={brace,amplitude=5mm},thick]
\namebraceright{tx}{rx}
\namebraceleft{k}{n}
\namebraceright{k}{n}
\namebraceleft{i}{t}
\end{scope}
\end{namepartpicture}
Note that this scheme is deliberately redundant. For instance, when we are the initiator, then `txki = rxki = txkm = rxkt`. I.e. the initiator's transmission key is the responder's reception key. Since we are the initiator, the initiator's transmission key is also the transmission key of `mine` and the reception key of `theirs`.
There also is a -- now deprecated -- naming scheme:
\begin{namepartpicture}
\namepart{ini=Initiator,res=Responder,hs=Handshake}
\SingleNamePart[3.5cm]{enc}{\textunderscore{}enc}{Encryption}
\begin{scope}[decoration={brace,amplitude=5mm},thick]
\namebraceright{ini}{hs}
\namebraceleft{enc}{enc}
\end{scope}
\end{namepartpicture}
`ini_enc = txki = rxkr` and `res_enc = txkr = rxki`, but this usage is deprecated. The third name `hs_enc` is for encryption as part of the key exchange itself; this name is still in use.
### Labels
Fig. \ref{img:HashingTree} specifies multiple domain separators for various uses.
* `PROTOCOL` (`[0, PROTOCOL]`) – The global domain separator; used to generate more domain separators.
Immediately below the global domain separator, you can find:
* `"mac"` – Network package integrity verification and pre-authentication with `spkt`. See Sec. \ref{envelope-mac-field}.
* `"cookie"` – Denial of Service mitigation through proof-of-ip ownership. See Sec. \ref{dos-mitigation}.
* `"peer id"` – Generation of peer ids. See Sec. \ref{peer-ids}.
* `"biscuit additional data"` – Storing the protocol state in encrypted cookies so the responder is stateless. See Sec. \ref{hs-state-and-biscuits}.
* `"chaining key init"` – Starting point for the execution of the actual rosenpass protocol.
* `"chaining key extract"` – Key derivation from the current protocol state, the chaining key. See Sec. \ref{symmetric-keys}.
Below `"chaining key extract"`, there are multiple labels, generating domain separators for deriving keys for various purposes during the execution of the protocol.
It is important to understand that there are two phases for these labels, e.g. applying the `"mix"` label produces a random fixed-size hash value we call `mix`. Not the label `"mix"` but the resulting hash value is used to derive keys during protocol execution. This allows us to use very complicated label structures for key derivation without losing efficiency.
The different labels are:
* `"mix"` – Mixing further values into the chaining key; i.e. into the protocol state.
* `"user"` – Labels for external uses; these are what generate the `osk` (output shared key). See Sec. \ref{symmetric-keys}.
* `"handshake encryption"` – Used when encrypting data using a shared key as part of the protocol execution; e.g. used to generate the `auth` (authentication tag) fields in protocol packages.
* `"initiator handshake encryption"` and `"responder handshake encryption"` – For transmission of data after the key-exchange finishes. See Sec. \ref{symmetric-keys}.
## Hashes
Rosenpass uses a cryptographic hash function for multiple purposes:
* Computing the message authentication code in the message envelope as in WireGuard
* Computing the cookie to guard against denial of service attacks. This is a feature adopted from WireGuard, but not yet included in the implementation of Rosenpass.
* Computing the cookie to guard against denial of service attacks.
* Computing the peer ID
* Key derivation during and after the handshake
* Computing the additional data for the biscuit encryption, to provide some privacy for its contents
Recall from Section \ref{hash} that rosenpass supports using either BLAKE2s or SHAKE256 as hash function, which can be configured for each peer ID. However, as noted above, rosenpass uses a hash function to compute the peer ID and thus also to access the configuration for a peer ID. This is an issue when receiving an `InitHello`-message, because the correct hash function is not known when a responder receives this message and at the same the responders needs it in order to compute the peer ID and by that also identfy the hash function for that peer. The reference implementation resolves this issue by first trying to derive the peer ID using SHAKE256. If that does not work (i.e. leads to an AEAD decryption error), the reference implementation tries again with BLAKE2s. The reference implementation verifies that the hash function matches the one confgured for the peer. Similarly, if the correct peer ID is not cached when receiving an InitConf message, the reference implementation proceeds in the same manner.

Using one hash function for multiple purposes can cause real-world security issues and even key recovery attacks [@oraclecloning]. We choose a tree-based domain separation scheme based on a keyed hash function – the previously introduced primitive `hash` – to make sure all our hash function calls can be seen as distinct.

Each tree node $\circ{}$ in Figure \ref{img:HashingTree} represents the application of the keyed hash function, using the previous chaining key value as first parameter. The root of the tree is the zero key. In level one, the `PROTOCOL` identifier is applied to the zero key to generate a label unique across cryptographic protocols (unless the same label is deliberately used elsewhere). In level two, purpose identifiers are applied to the protocol label to generate labels to use with each separate hash function application within the Rosenpass protocol. The following layers contain the inputs used in each separate usage of the hash function: Beneath the identifiers `"mac"`, `"cookie"`, `"peer id"`, and `"biscuit additional data"` are hash functions or message authentication codes with a small number of inputs. The second, third, and fourth column in Figure \ref{img:HashingTree} cover the long sequential branch beneath the identifier `"chaining key init"` representing the entire protocol execution, one column for each message processed during the handshake. The leaves beneath `"chaining key extract"` in the left column represent pseudo-random labels for use when extracting values from the chaining key during the protocol execution. These values such as `mix >` appear as outputs in the left column, and then as inputs `< mix` in the other three columns.
The protocol identifier depends on the hash function used with the respective peer is defined as follows if BLAKE2s [@rfc_blake2] is used:

Note that the domain separator used here maintains that BLAKE2s is used, while in
reality, we use BLAKE2b. The reason for this is an implementation error.

The Rosenpass protocol uses various timer-triggered events during its operation. This section provides a listing of the timers used and gives the values used in the reference implementation. Other implementations may choose different values.
### Rekeying
Period after which the previous responder starts a new handshake in initiator role; period after which the previous initiator starts a new handshake in initiator role again; period after which a peer rejects an existing shared key.

### Retransmission
Delay after which all retransmission attempts are aborted; exponential backoff factor for retransmission delay; initial (minimum) retransmission delay; final (maximum) retransmission delay; retransmission jitter/variance factor.

# Protocol extensions {#protocol-extensions}
The main extension point for the Rosenpass protocol is to generate `osk`s (speak output shared keys, see Sec. \ref{symmetric-keys}) for purposes other than using them to secure WireGuard. By default, the Rosenpass application generates keys for the WireGuard PSK (see \ref{protocol-extension-wireguard-psk}). It would not be impossible to use the keys generated for WireGuard in other use cases, but this might lead to attacks[@oraclecloning]. Specifying a custom protocol extension in practice just means settling on alternative domain separators (see Sec. \ref{symmetric-keys}, Fig. \ref{img:HashingTree}).

# Errata {#errata}
## Incorrect HMAC, Hash Function Choice {#incorrect-hmac}
Initially, we chose to use `HMAC+BLAKE2s` for our message authentication code, mostly as a form of cargo cult. WireGuard used BLAKE2s, so we should use it too. BLAKE2 supports a directly keyed mode, so there is not much reason to prefer rolling your own using HMAC from a security standpoint.
It seems likely that WireGuard used HMAC as a heuristic security measure. Message authentication codes, keyed hash functions, had long been constructed by combining HMAC with a hash function; why change that? And there actually is a good reason to use HMAC: Merkle-Damgard constructions have long been the norm for hash functions; their usage was even standardized as MD5 or SHA-2. But Merkle-Damgard constructions are susceptible to extension attacks, where you can calculate `H(message || suffix)` assuming `H(message)` is known to you. HMAC fixes this issue[@boneh_shoup_graduate][@hmac].
But SHA-3 (or SHAKE) and BLAKE2 depart from this long-standing status quo: these hash functions are not based on Merkle-Damgard and they are deliberately designed so they are not susceptible to length extension attacks. On top of this, both schemes provide a keyed mode as a feature of the hash function. At this point it makes much more sense to require a keyed hash function, satisfying the PRF ("pseudo random function") security property and the PRF-SWAP security property[@pqwg] instead of building our own keyed hash from a hash function. HMAC can still be used; if someone wanted to operate Rosenpass with SHA2, the best way to do it would be using `HMAC-SHA512` as the underlying keyed hash. We just also allow using `SHAKE256` without an extra application of HMAC.
Unfortunately, there were a couple of errors in the implementation: we should have used BLAKE2s like WireGuard; instead, we used BLAKE2b. We should have implemented HMAC properly, but we failed to do so. For a fixed-length, 32 byte key and a 32 byte block size, the HMAC function is specified as:
```pseudorust
type Key = [u8; 32];
type HashFunction = Fn(&[u8]) -> Key;
const INNER_PAD: [u8; KEY_LEN] = [0x36u8; KEY_LEN];
const OUTER_PAD: [u8; KEY_LEN] = [0x5Cu8; KEY_LEN];
fn hmac<Hash: HashFunction>(h: Hash, key: Key, data: &[u8]) -> Key {
// `^` denotes XOR, `||` denotes concatenation
let inner_key = key ^ INNER_PAD;
let outer_key = key ^ OUTER_PAD;
let inner_hash = h(inner_key || data);
let outer_hash = h(outer_key || inner_hash);
return outer_hash;
}
```
Instead of implementing this function, we somehow lost track of the fact that HMAC uses concatenation to combine the keys with its data, and instead we built a construction around BLAKE2b in keyed hash mode. That is, we replaced the concatenation with calls to the keyed version of our hash:
```pseudorust
type Key = [u8; 32];
type KeyedHashFunction = Fn(Key, &[u8]) -> Key;
const INNER_PAD: [u8; KEY_LEN] = [0x36u8; KEY_LEN];
const OUTER_PAD: [u8; KEY_LEN] = [0x5Cu8; KEY_LEN];
fn incorrect_rosenpass_hmac<KeyedHash: KeyedHashFunction>(kh: KeyedHashFunction, key: Key, data: &[u8]) -> Key {
// `^` denotes XOR, `||` denotes concatenation
let inner_key = key ^ INNER_PAD;
let outer_key = key ^ OUTER_PAD;
let inner_hash = kh(inner_key, data);
let outer_hash = kh(outer_key, inner_hash);
return outer_hash;
}
```
We therefore add this section explaining our incorrect HMAC usage to harmonize the white paper with the implementation.
To ensure compatibility with the existing versions of Rosenpass, you have to replicate this incorrect variant of HMAC.
Neither mistake is assumed to cause security issues. BLAKE2b is a secure hash function.
There is no reason to assume that our incorrect variant of HMAC-BLAKE2b would be insecure; it is, however, non-standard and needlessly complicates the protocol. We are therefore phasing out usage of HMAC-BLAKE2b in favor of us using SHAKE256 as our keyed hash of choice.

### 0.3.x
#### 2025-08-10 – Applying fixes from Steffen Vogel proof reading of the whitepaper
\vspace{0.5em}
Author: Karolin varner
Issue: [#68](https://github.com/rosenpass/rosenpass/issues/68)
PR: [#664](https://github.com/rosenpass/rosenpass/)
\vspace{0.5em}
Early in the project lifetime, Steffen Vogel successfully implemented a [port of the Rosenpass protocol in [go](https://github.com/cunicu/go-rosenpass).
This implementation has not received an in-depth review from a cryptography implementation perspective, which is why we (the Rosenpass project) are not yet recommending this implementation for production usage;
still, creating this implementation was a great achievement.
During the process, Steffen discovered a large number of possible improvements for the whitepaper. With this update, we are addressing those issues.
This process also ensures that the world knows, that I have ADHD and makes me fix all the little mistakes I could not spot even on the seventh review of the whitepaper.
Changes, in particular:
1. Added a comprehensive reference about labels used in the protocol
2. Added a comprehensive reference about symmetric keys and nonces used for encryption/decryption (`txki`, `txni`, `ini_enc`, `hs_enc`, …)
3. Added a comprehensive reference about packages used.
4. Added an explaining paragraph to section "Live Session State".
5. Added a section about protocol roles.
6. Brief section about endianness.
7. In Fig. 5: Rosenpass Message Handling Code; in IHR5 we replace
``` {=tex}
\begin{quote}
\begin{minted}{pseudorust}
decaps_and_mix<SKEM>(sskr, spkr, ct1)
\end{minted}
\end{quote}
```
by
``` {=tex}
\begin{quote}
\begin{minted}{pseudorust}
decaps_and_mix<SKEM>(sskr, spkr, sctr)
\end{minted}
\end{quote}
```
8. In `load_biscuit()`, there was a typo doing an incorrect comparison between `biscuit_no` and `biscuit_used`. This is not a security issue, as a verbatim implementation would simply have lead to a non-functional implementation. We replace
``` {=tex}
\begin{quote}
\begin{minted}{pseudorust}
assert(pt.biscuit_no <= peer.biscuit_used);
\end{minted}
\end{quote}
```
by
``` {=tex}
\begin{quote}
\begin{minted}{pseudorust}
assert(pt.biscuit_no >= peer.biscuit_used);
\end{minted}
\end{quote}
```
9. In the whitepaper we used the labels `"initiator session encryption"` and `"responder session encryption"`, but in the implementation we used `"initiator handshake encryption"` and `"responder handshake encryption"`. While the whitepaper was correct and the implementation was not, we opt to harmonize the whitepaper with the implementation to avoid a breaking change.
10. The protocol strings used in the whitepaper where different to the ones used in the implementation. We harmonize the two by updating the whitepaper to reflect the protocol identifier used in the implementation. We substitute
``` {=tex}
\begin{quote}
The protocol identifier depends on the hash function used with the respective peer is defined as follows if BLAKE2s is used:
\begin{minted}{pseudorust}
PROTOCOL = "rosenpass 1 rosenpass.eu aead=chachapoly1305 hash=blake2s ekem=kyber512 skem=mceliece460896 xaead=xchachapoly1305"
\end{minted}
If SHAKE256 is used, \texttt{blake2s} is replaced by \texttt{shake256} in \texttt{PROTOCOL}.
\end{quote}
```
with
``` {=tex}
\begin{quote}
The protocol identifier depends on the hash function used with the respective peer is defined as follows if BLAKE2s is used:
\begin{minted}{pseudorust}
PROTOCOL = "Rosenpass v1 mceliece460896 Kyber512 ChaChaPoly1305 BLAKE2s"
\end{minted}
If SHAKE256 is used, then \texttt{BLAKE2s} is substituted with \texttt{SHAKE256}:
\begin{minted}{pseudorust}
PROTOCOL = "Rosenpass v1 mceliece460896 Kyber512 ChaChaPoly1305 SHAKE256"
\end{minted}
\end{quote}
```
11. The whitepaper stated that Rosenpass uses BLAKE2s, while the implementation used BLAKE2b; we update the whitepaper to reflect that reality. The places where this substitution happened are a bit too numerous to count them all here. On top of this, we added the following paragraph to explain the discrepancy between `PROTOCOL` and actual hash function used:
``` {=tex}
\begin{quote}
Note that the domain separator used here maintains that BLAKE2s is used, while in
reality, we use BLAKE2b. The reason for this is an implementation error. Since fixing this would have led to a breaking change in the Rosenpass reference implementation, and all other known implementations of Rosenpass simply reproduced this error, we chose to harmonize the white paper with the implementation instead of fixing the implementation.
\end{quote}
```
12. Added a section to explain and specify our incorrect implementation of HMAC-BLAKE2b.
13. In `encaps_and_mix()`/`decaps_and_mix()` the whitepaper stated that public key, ciphertext, and shared key are mixed into the chaining key in that order, but the implementation used a different order: public key, shared key, and ciphertext (shared key and ciphertext are swapped). We harmonize the white paper with the implementation.
14. In the white paper, in package `RespHello` the field `auth` was indicated to come after `biscuit`, but in the implementation, `auth` came first and `biscuit` was last. The semantics of how fields in Rosenpass messages are processed generally demand that fields are processed in the order they appear in the message, so having `biscuit` first and `auth` second—as was done in the white paper—would be correct; still, we harmonize the white paper with the implementation.
15. Fix a discrepancy with regard to biscuit key life times.
``` {=tex}
\begin{quote}
The \texttt{biscuit\textunderscore{}key} used to encrypt biscuits should be rotated every two minutes. Implementations should keep two biscuit keys in memory at any given time to avoid having to drop packages when \texttt{biscuit\textunderscore{}key} is rotated.
\end{quote}
```
by
``` {=tex}
\begin{quote}
The \texttt{biscuit\textunderscore{}key} used to encrypt biscuits should be rotated frequently. Implementations should keep two biscuit keys in memory at any given time to avoid having to drop packages when \texttt{biscuit\textunderscore{}key} is rotated. The Rosenpass reference implementation retires biscuits after five minutes and erases them after ten.
\end{quote}
```
16. Point out explicitly that we use KEMs from NIST-Competition Round 3. Include links to the competition submission packages. Update citations to reflect the exact specification version.
17. Consistent naming convention. Always use the term `secret key`, never `private key`.
18. `pidiC` -> `pidi_ct`; to make it clearer that this is a cipher text
19. Where we refer to the biscuit ciphertext, we now use the term `biscuit_ct`. Previously we had used various variable names such as `nct` (nonce followed by cipher text) or just plain `biscuit`.
20. In `load_biscuit`, we make it clear that destructuring of `biscuit_ct` destructures a concatenation.
``` {=tex}
\begin{quote}
\begin{minted}{pseudorust}
let (n, ct) = biscuit_ct;
\end{minted}
\end{quote}
```
with
``` {=tex}
\begin{quote}
\begin{minted}{pseudorust}
let concat(n, ct) = biscuit_ct;
\end{minted}
\end{quote}
```
21. Added a section about timers used in the Rosenpass protocol
Additional changes (also motivated by a close review, but not reported by Steffen):
1. Fig. 2 "Rosenpass Message Types", CookieReply package. Renamed the length sum from payload to package.
2. Fig. 2 "Rosenpass Message Types", Envelope package. Renamed the length sum from envelope to package.
3. In `load_biscuit()` fix a naming typo:
``` {=tex}
\begin{quote}
\begin{minted}{pseudorust}
lookup_peer(pt.peerid);
\end{minted}
\end{quote}
```
with
``` {=tex}
\begin{quote}
\begin{minted}{pseudorust}
lookup_peer(pt.pidi);
\end{minted}
\end{quote}
```
4. Remove reference to the proof-of-IP-ownership-based DoS mitigation feature not being implemented. Add a notice, that the feature is currently experimental.
5. Fixed a few typos and capitalization issues
