Every transaction can have zero or more announcements, which are essentially
messages that must be included across all future mergers and updates.
Announcements are typically used for transmitting information related to
receiving UTXOs, encrypted. However, a new use case is that of *transparent
transaction info*, which is an announcement containing the UTXOs and the
commitment randomnesses needed to reproduce the transaction's inputs and
outputs. With such a transparent transaction info announcement, third parties
can transparently audit transactions.
This commit adds a page for viewing announcements, and if the announcement can
be parsed as a transparent transaction info type announcement then it is
rendered as such, complete with native currency amounts and linkable UTXOs
(where possible).
The path for accessing announcements is any of
- `/announcement/digest/<hex-string>/<index>`
- `/announcement/tip/<index>`
- `/announcement/genesis/<index>`
- `/announcement/height/<height>/<index>`
- `/announcement/height_or_digest/<height-or-diges>/index/<index>`.
The last bullet point exists to support the quick lookup functionality, which is
also new. A `AnnouncementSelector` has display and from-string methods relating
these path formats to the relevant object. A suite of (prop)tests verifies
parsing.
Also, this commit enables mocking, which is useful when the neptune-core node
the explorer is connected to is outdated, unsynced, or for whatever reason does
not serve the desired data. The RPC client call is intercepted, and if it fails
and mocking is enabled, an imagined (pseudorandom) resource of the requested
type is returned. To enable mocking, compile with the "mock" feature flag and
set the "MOCK" environment variable.
Closes#5
Addresses #6
changes:
* field Mining Reward --> Coinbase. (actual reward)
* add field Expected Coinbase (expected/calced reward)
this field only displays if different from actual coinbase.
* add field Cumulative Proof-of-Work
* change tooltip 🛈 --> ⓘ . for mobile devices. (hopefully)
* css: make tooltip text bold, so the ⓘ is stronger.
implements a generic solution to redirect query strings generated by
forms to path based URIs that can be handled by existing routes.
This eliminates the need for javascript that was doing the equivalent
client-side.
Changes:
+ present not-found page for unhandled uri paths, eg /stuff
+ display the tip-height on front page
+ add favicon and neptune logo to front page
+ use ServerDir instead of ServeFile for /image and /css
+ add help tooltips for fields on front page
+ use monospace font for digests
Changes:
1. integrates pico minimal responsive css framework for light/dark
themes and overall better looks.
2. adds a not-found page for bad url queries.
3. catches axum/serde deserialization errors of user input and routes
them to the not-found page with a helpful hint (parse error msg)
