feat: limit event publishing to NIP-05 verified users

# Author Verification Design Document
|
||||
|
||||
The relay will use NIP-05 DNS-based author verification to limit which
|
||||
authors can publish events to a relay. This document describes how
|
||||
this feature will operate.
|
||||
|
||||
## Considerations
|
||||
|
||||
DNS-based author verification is designed to be deployed in relays that
|
||||
want to prevent spam, so there should be strong protections to prevent
|
||||
unauthorized authors from persisting data. This includes data needed to
|
||||
verify new authors.
|
||||
|
||||
There should be protections in place to ensure the relay cannot be
|
||||
used to spam or flood other webservers. Additionally, there should be
|
||||
protections against server-side request forgery (SSRF).
|
||||
|
||||
## Design Overview
|
||||
|
||||
### Concepts
|
||||
|
||||
All authors are initially "unverified". Unverified authors that submit
|
||||
appropriate `NIP-05` metadata events become "candidates" for
|
||||
verification. A candidate author becomes verified when the relay
|
||||
inspects a kind `0` metadata event for the author with a `nip05` field,
|
||||
and follows the procedure in `NIP-05` to successfully associate the
|
||||
author with an internet identifier.
|
||||
|
||||
The `NIP-05` procedure verifies an author for a fixed period of time,
|
||||
configurable by the relay operator. If this "verification expiration
|
||||
time" (`verify_expiration`) is exceeded without being refreshed, they
|
||||
are once again unverified.
|
||||
|
||||
Verified authors have their status regularly and automatically updated
|
||||
through scheduled polling to their verified domain, this process is
|
||||
"re-verification". It is performed based on the configuration setting
|
||||
`verify_update_frequency`, which defines how long the relay waits
|
||||
between verification attempts (whether the result was success or
|
||||
failure).
|
||||
|
||||
Authors may change their verification data (the internet identifier from
|
||||
`NIP-05`) with a new metadata event, which then requires
|
||||
re-verification. Their old verification remains valid until
|
||||
expiration.
|
||||
|
||||
Performing candidate author verification is a best-effort activity and
|
||||
may be significantly rate-limited to prevent relays being used to
|
||||
attack other hosts. Candidate verification (untrusted authors) should
|
||||
never impact re-verification (trusted authors).
|
||||
|
||||
## Operating Modes
|
||||
|
||||
The relay may operate in one of three modes. "Disabled" performs no
|
||||
validation activities, and will never permit or deny events based on
|
||||
an author's NIP-05 metadata. "Passive" performs NIP-05 validation,
|
||||
but does not permit or deny events based on the validity or presence
|
||||
of NIP-05 metadata. "Enabled" will require current and valid NIP-05
|
||||
metadata for any events to be persisted. "Enabled" mode will
|
||||
additionally consider domain whitelist/blacklist configuration data to
|
||||
restrict which author's events are persisted.
|
||||
|
||||
## Design Details
|
||||
|
||||
### Data Storage
|
||||
|
||||
Verification is stored in a dedicated table. This tracks:
|
||||
|
||||
* `nip05` identifier
|
||||
* most recent verification timestamp
|
||||
* most recent verification failure timestamp
|
||||
* reference to the metadata event (used for tracking `created_at` and
|
||||
`pubkey`)
|
||||
|
||||
### Event Handling
|
||||
|
||||
All events are first validated to ensure the signature is valid.
|
||||
|
||||
Incoming events of kind _other_ than metadata (kind `0`) submitted by
|
||||
clients will be evaluated as follows.
|
||||
|
||||
* If the event's author has a current verification, the event is
|
||||
persisted as normal.
|
||||
* If the event's author has either no verification, or the
|
||||
verification is expired, the event is rejected.
|
||||
|
||||
If the event is a metadata event, we handle it differently.
|
||||
|
||||
We first determine the verification status of the event's pubkey.
|
||||
|
||||
* If the event author is unverified, AND the event contains a `nip05`
|
||||
key, we consider this a verification candidate.
|
||||
* If the event author is unverified, AND the event does not contain a
|
||||
`nip05` key, this is not a candidate, and the event is dropped.
|
||||
|
||||
* If the event author is verified, AND the event contains a `nip05`
|
||||
key that is identical to the currently stored value, no special
|
||||
action is needed.
|
||||
* If the event author is verified, AND the event contains a different
|
||||
`nip05` than was previously verified, with a more recent timestamp,
|
||||
we need to re-verify.
|
||||
* If the event author is verified, AND the event is missing a `nip05`
|
||||
key, and the event timestamp is more recent than what was verified,
|
||||
we do nothing. The current verification will be allowed to expire.
|
||||
|
||||
### Candidate Verification
|
||||
|
||||
When a candidate verification is requested, a rate limit will be
|
||||
utilized. If the rate limit is exceeded, new candidate verification
|
||||
requests will be dropped. In practice, this is implemented by a
|
||||
size-limited channel that drops events that exceed a threshold.
|
||||
|
||||
Candidates are never persisted in the database.
|
||||
|
||||
### Re-Verification
|
||||
|
||||
Re-verification is straightforward when there has been no change to
|
||||
the `nip05` key. A new request to the `nip05` domain is performed,
|
||||
and if successful, the verification timestamp is updated to the
|
||||
current time. If the request fails due to a timeout or server error,
|
||||
the failure timestamp is updated instead.
|
||||
|
||||
When the the `nip05` key has changed and this event is more recent, we
|
||||
will create a new verification record, and delete all other records
|
||||
for the same name.
|
||||
|
||||
Regarding creating new records vs. updating: We never update the event
|
||||
reference or `nip05` identifier in a verification record. Every update
|
||||
either reset the last failure or last success timestamp.
|
||||
|
||||
### Determining Verification Status
|
||||
|
||||
In determining if an event is from a verified author, the following
|
||||
procedure should be used:
|
||||
|
||||
Join the verification table with the event table, to provide
|
||||
verification data alongside the event `created_at` and `pubkey`
|
||||
metadata. Find the most recent verification record for the author,
|
||||
based on the `created_at` time.
|
||||
|
||||
Reject the record if the success timestamp is not within our
|
||||
configured expiration time.
|
||||
|
||||
Reject records with disallowed domains, based on any whitelists or
|
||||
blacklists in effect.
|
||||
|
||||
If a result remains, the author is treated as verified.
|
||||
|
||||
This does give a time window for authors transitioning their verified
|
||||
status between domains. There may be a period of time in which there
|
||||
are multiple valid rows in the verification table for a given author.
|
||||
|
||||
### Cleaning Up Inactive Verifications
|
||||
|
||||
After a author verification has expired, we will continue to check for
|
||||
it to become valid again. After a configurable number of attempts, we
|
||||
should simply forget it, and reclaim the space.
|
||||
|
||||
### Addition of Domain Whitelist/Blacklist
|
||||
|
||||
A set of whitelisted or blacklisted domains may be provided. If both
|
||||
are provided, only the whitelist is used. In this context, domains
|
||||
are either "allowed" (present on a whitelist and NOT present on a
|
||||
blacklist), or "denied" (NOT present on a whitelist and present on a
|
||||
blacklist).
|
||||
|
||||
The processes outlined so far are modified in the presence of these
|
||||
options:
|
||||
|
||||
* Only authors with allowed domains can become candidates for
|
||||
verification.
|
||||
* Verification status queries additionally filter out any denied
|
||||
domains.
|
||||
* Re-verification processes only proceed with allowed domains.
|
||||
|
||||
### Integration
|
||||
|
||||
We have an existing database writer thread, which receives events and
|
||||
attempts to persist them to disk. Once validated and persisted, these
|
||||
events are broadcast to all subscribers.
|
||||
|
||||
When verification is enabled, the writer must check to ensure a valid,
|
||||
unexpired verification record exists for the auther. All metadata
|
||||
events (regardless of verification status) are forwarded to a verifier
|
||||
module. If the verifier determines a new verification record is
|
||||
needed, it is also responsible for persisting and broadcasting the
|
||||
event, just as the database writer would have done.
|
||||
|
||||
## Threat Scenarios
|
||||
|
||||
Some of these mitigations are fully implemented, others are documented
|
||||
simply to demonstrate a mitigation is possible.
|
||||
|
||||
### Domain Spamming
|
||||
|
||||
*Threat*: A author with a high-volume of events creates a metadata event
|
||||
with a bogus domain, causing the relay to generate significant
|
||||
unwanted traffic to a target.
|
||||
|
||||
*Mitigation*: Rate limiting for all candidate verification will limit
|
||||
external requests to a reasonable amount. Currently, this is a simple
|
||||
delay that slows down the HTTP task.
|
||||
|
||||
### Denial of Service for Legitimate Authors
|
||||
|
||||
*Threat*: A author with a high-volume of events creates a metadata event
|
||||
with a domain that is invalid for them, _but which is used by other
|
||||
legitimate authors_. This triggers rate-limiting against the legitimate
|
||||
domain, and blocks authors from updating their own metadata.
|
||||
|
||||
*Mitigation*: Rate limiting should only apply to candidates, so any
|
||||
existing verified authors have priority for re-verification. New
|
||||
authors will be affected, as we can not distinguish between the threat
|
||||
and a legitimate author. _(Unimplemented)_
|
||||
|
||||
### Denial of Service by Consuming Storage
|
||||
|
||||
*Threat*: A author creates a high volume of random metadata events with
|
||||
unique domains, in order to cause us to store large amounts of data
|
||||
for to-be-verified authors.
|
||||
|
||||
*Mitigation*: No data is stored for candidate authors. This makes it
|
||||
harder for new authors to become verified, but is effective at
|
||||
preventing this attack.
|
||||
|
||||
### Metadata Replay for Verified Author
|
||||
|
||||
*Threat*: Attacker replays out-of-date metadata event for a author, to
|
||||
cause a verification to fail.
|
||||
|
||||
*Mitigation*: New metadata events have their signed timestamp compared
|
||||
against the signed timestamp of the event that has most recently
|
||||
verified them. If the metadata event is older, it is discarded.
|
||||
|
||||
### Server-Side Request Forgery via Metadata
|
||||
|
||||
*Threat*: Attacker includes malicious data in the `nip05` event, which
|
||||
is used to generate HTTP requests against potentially internal
|
||||
resources. Either leaking data, or invoking webservices beyond their
|
||||
own privileges.
|
||||
|
||||
*Mitigation*: Consider detecting and dropping when the `nip05` field
|
||||
is an IP address. Allow the relay operator to utilize the `blacklist`
|
||||
or `whitelist` to constrain hosts that will be contacted. Most
|
||||
importantly, the verification process is hardcoded to only make
|
||||
requests to a known url path
|
||||
(`.well-known/nostr.json?name=<LOCAL_NAME>`). The `<LOCAL_NAME>`
|
||||
component is restricted to a basic ASCII subset (preventing additional
|
||||
URL components).
