NewbieActivity: 20Merit: 0 Introducing OXT Landscapes (aka "blockchain analytics on acid") May 09, 2016, 12:34:22 PM #22



So here comes OXT Landscapes, an interactive 3D visualization displaying the blockchain as a point cloud (every block is displayed as a particle). The principle is straightforward: define a "scene" by selecting a metrics for each axis (size of block, #transactions in block, etc.), click on "Build" et voila ! You're ready for a 3-dimensional exploration of the scene.



Here's a



Extra bonus for the most adventurous among you: I've added basic support of VR for the Oculus Rift (DK2 or CV1 recommended). I wouldn't recommend it for data analysis but it seems quite promising in terms of psychedelic experimentations

Requirements & Tips



Desktop version



You'll need a recent web browser supporting WebGL. It works fine with recent versions of Chrome (recommended for best performances) and Firefox and it should work with IE11.

It requires the download of a large dataset (stats for blocks 1 to 400,000). Do not try to use it on a mobile device.

Notes about the input controllers:

Default input controller is a "trackball". It's really easy to use (mouse or trackpad) but it provides limited features (rotation of the scene and zoom). Recommanded controller is the "fly controller". It allows a 3-dimensional exploration of the scene. A tip if you want to use it with your mouse: the position of the mouse on the screen controls camera rotations. The center of the screen is the "rest position".

Control Panel at the bottom of the screen can be hidden/displayed thanks to the arrow on the right side.

The 4 icons on the left side will teleport you at 4 predefined locations (useful if you get lost)

If the scene seems desperately flat, try to regenerate the scene with a logarithmic scale for the "flat axis".

If you find a combination of parameters producing a nice scene, be kind and share it with the rest of us !

VR version



You'll need to install a web browser supporting WebVR (Firefox nightly build with Oculus Rift enabler installed or experimental build of Chrome).

Go to this website for links & instructions Install the web browser Test your setup with this sample

When your setup for webvr is ok, launch Landscapes

Random tips:

I wouldn't recommend the DK1 (low resolution) but if you want to give it a try, you'll need to use the Oculus runtime 0.5.0.1 + Chromium experimental build (04/21/2015) You can reset the orientation of your headset with key "I". All movements are controlled thanks to the keyboard (get comfortable with the commands in desktop mode before using them in VR...). If you use an AZERTY keyboard, hit key "P". Hit key "O" to select the QWERTY mode (default). Use the numeric keypad (1 to 7) to load a prebuilt scene. For now, it's not possible to build your own scene in VR mode. Key "T" allows to switch speed mode. I recommend to use the slow speed when you're moving inside the cloud. For fun: explore a scene, then rotate the camera 90° or 180° (the grid which was the ground becomes a wall or the roof) and start a new exploration...

I've been wanting to create something special to celebrate the next halving and the 7 years of bitcoin for a while. Something fun and intended for the broadest audience.So here comes OXT Landscapes, an(every block is displayed as a particle).

I may raise current limits in the future if I can secure a more powerful infrastructure.



I'll check why the message doesn't disappear. This is clearly a bug.



Thanks for the feedback !

And this one is an "important" milestone for OXT



Since its inception, I've envisioned OXT as an interactive map of the bitcoin economy and for more than one year the platform has tried to provide a first (but imperfect) version of this map. But an important ingredient was still missing.



This missing part was a set of features offering a more personal experience, like the possibility to annotate objects (block, transaction, etc).



A lot remains to be done but I hope this new version will improve your experience with the platform and that it will foster collaboration between OXT users.



Improvements



- Support of registered accounts

- Authentication by login/password

- Password reset managed thanks to the signature of a challenge with a "bitcoin address"



- Support of annotations

- Registered users can add notes to Blocks, Transactions, Addresses & Entities

- Annotations are public and visible by all users (registered or anon.)



- Support of "rich" bookmarks

- Registered users can create bookmarks pointing to specific pages of OXT

- A bookmark can be enriched with a title and a description displayed to readers before the target page is displayed

- Bookmarks store the current view of the page (active tab, selected chart, transactions filter, etc)

- Bookmarks are public and visible by all users (registered or anon.)



- MY OXT

- A personal workspace allowing registered users to manage their annotations and bookmarks



- Contextual Toolbox

- A contextual toolbox is now displayed on the left hand side of the screen

- Some existing action buttons/icons (display tx in graphalizer, prev/next block, etc) have been moved to this toolbox



- Bitcoin History

- A page listing a few famous bitcoin events illustrated with specific objects or chart provided by OXT



- The Bitcoin "RichList"

- Ordered list of addresses with a balance greater than 1,000 btc

Improvements



Chart of UTXOs controlled by the entities

Entity pages now display a tab with statistics about the utxos supposedly controlled by the entity:

- #utxos consumed by the entity during a given period

- #utxos created by the entity during a given period

- average #utxos per tx consumed by the entity during a given period

- average #utxos per tx created by the entity during a given period



OXT Directory

- The directory lists the entities which have been tagged in OXT

- Entities are categorized by sector of activity

- The directory can be accessed from the "Charts & Resources" menu



Support of most recent transactions by the search engine

The search engine now supports transactions included in the most recent blocks and transactions from the mempool



New advanced features

This version includes a set of new features which will be accessible to a small group of beta users for testing. If everything goes fine, these features will be released in the coming months.
