Censorship resistant location-based messages that empowers anyone to have a voice

LocPost

The censorship resistant messaging app that empowers anyone to communicate anonymously around a location.

Check it out online at https://tomyo.github.io/locpost/ and join our public room on Matrix: #locpost:matrix.org.

We use GUN to create a distributed database which is stored amongst the network participants in their local storage inside the web browser. Each participant will keep a copy of the database and GUN will take care of keeping them in sync.

By giving access to your device location, you will join a censorship-resistant channel to exchange messages around that area.

locpost's Issues

Enable adding content

As a user, I want to be able to POST content (messages) to a specific location.

Register / create / submit Project

ethberlin.devfolio.co

DO NOT FORGET specifics:

• Relevant/selected Track == Even the Odds: Empowering the underprivileged. Topics: Social Justice, Inclusion, Sustainability, Public Goods.
• Check & participate in Open Track

Deadline 11 AM Sunday

Set up / update (test) host/server

http://10.0.0.172:8000/ is slow.

Please remember to regularly push updates.
Ideally, notify! ;)

Create presentation

Create a short presentation file that describes the project.

Clean up UI

See also https://office.ethberlin.ooo/pad/#/3/pad/edit/ecd4b5f7d264a6cd8087ea96a0db8100/, 'Design' section!

Do not forget Mark and/or Mentor/s.

List content

For now, messages.

As a user, I want to see all content linked to a certain location.

Investigate eligibility for Sponsor Bounties

Two Sponsor Tracks pre-selected as 'maybe'.

Please advise on if & how we should participate in those 'Tracks', as well (and what that implies for last minute work).

1. Hyperlane Interchain 4k ethb3rlin/sponsor-bounties#8
2. Manta 'privacy' 2.5k ethb3rlin/sponsor-bounties#9

Allow specifying how big is the area around you in Km

Maybe we could use something like jscoord:

            LatLng lld1 = new LatLng(40.718119, -73.995667);
            LatLng lld2 = new LatLng(51.499981, -0.125313);
            Double distance = lld1.distance(lld2);
            Log.d(TAG, "Distance in kilometers " + distance);

Set manual location

As a user, in order to access the content within a certain location (and to not be dependent on GPS-/network-based location data), I want to click a button 'Set location', and then* be presented with a map that includes a search function, navigate to a certain location, and confirm said location.
*One alternative/additional in the 'manual select' interface might be a directory/list of locations, rather than (merely) a map view

Based upon user input, a new map tile & subsequent location is loaded. The button 'set location' persists in this view, as well.

The error "user has denied location access" should be removed.

Define & insofar possible implement (persistent) account management

As a user, I want to be able to claim (and maintain, and be able to select) a certain identity, in order to keep posting with my unique name, and to prevent others from pretending they are me i.e. to prevent 'identity theft'.

Extend with 0x/wallet functionality?

Prevent 'empty' posts

Repro:

• click +
• click Post

Actual result:
It is possible to post a message without any body (actual content) in it.

Expected Result:
An exception message is thrown if user input = NULL. No POST takes place.

Display enriched context/location information

As a user, at the top of posts page, I want to see which (approximate) location I am 'at', in order to understand more context in relation to whatever I see, and perhaps add to.

Ideally, this is displayed by means of a map section, with the active map grid tile highlighted, within it.

Research/implement (more) permanent storage and/or valuations

EDIT: some storage(-related) stuff to consider (to consider).
IPFS
Pinata / zkSync
Ceramic
Lens (d.Twitter...?)
(Swarm?)

As a user, I want to use a certain Real Life value (such as the ETH on the ETHBerlin Goerli Testnet Cards) in order to enrich my own experience with & contribution to the LocPost ecosystem, as well as that of others.

The value add is being able to 'vote', and getting appreciated by others.

The 'power' required enables users to appreciate (e.g. upvote/like/love/...) our content, i.e. (for the moment only) messages.

We should CAP the maximum amount of impact a user can have, such as 5*/day. Please advise/conceptualize.
Please also advise on potential to present (e.g. auto-sort) location-based content.

Goal guideline:
Level 1: research & provide general insights/recommendations
Level 2: provide (minimal) PoC (text only)
Level 3 (stretch goal): create 'MVP' implementation e.g. interface to (bridge with / application of ETHBerlin Goerli Testnet Cards, allowing fellow hackers to use the TEST ETH provided to value posts within our system)
