|
<PRE>Dear All,
|
|
|
|
This e-mail contains the final report on the Zcash blockchain analysis
|
|
platform (GrantProposals-2018Q2, grant proposal #39).
|
|
|
|
Throughout the project we created a platform (called Dru*) that
|
|
facilitates the process of analysing blockchain data for network
|
|
scientists and other researchers in a number of aspects:
|
|
- centralized and always up-to-date blocks repository (delivered by the
|
|
block engine component) provides the possibility to access the
|
|
blockchain data without the necessity to have a local cryptocurrency
|
|
client up and running,
|
|
- the API endpoints let to run a number of network science queries that
|
|
can be helpful in looking at the variety of aspects of blokchain data,
|
|
- by the NoSQL storage of blockchain data researchers can easily perform
|
|
their own queries if they cannot find suitable ones in the endpoints
|
|
repository,
|
|
- it is also possible to export the edges and import them to local
|
|
programs created by researchers.
|
|
|
|
The Dru platform consists of two main components: the block engine (MIT
|
|
license) and the analytical platform itself (GNU GPL v3 license). It is
|
|
contained in a Docker image, so it is portable among variety of
|
|
platforms. Dru provides a queuing engine, so each query is being
|
|
executed in the backend. After submitting it, the researcher gets a link
|
|
with the details on the status of the query and can be also notified by
|
|
e-mail about the status of it.
|
|
|
|
The platform is compatible with any RPC-based altcoin client, yet the
|
|
development and testing was made with Zcash.
|
|
|
|
The code of the platform is located here:
|
|
<A HREF="https://github.com/bergplace/Dru">https://github.com/bergplace/Dru</A> and the documentation is here:
|
|
<A HREF="https://dru.readthedocs.io.">https://dru.readthedocs.io.</A> Within the Zcash grant we host also an
|
|
instance of Dru running on our server:
|
|
<A HREF="https://dru.readthedocs.io/en/docs/docs/server.html">https://dru.readthedocs.io/en/docs/docs/server.html</A>
|
|
|
|
The core developers of the platform are the following: Radosław
|
|
Michalski (PI & developer) Marcin Pieczka (lead developer), Wojciech
|
|
Puchta (developer) and Weronika Mrugała (developer).
|
|
|
|
Now, the Dru platform will be the main way of performing the blockchain
|
|
analyses by BERG (<A HREF="https://www.bergplace.org/">https://www.bergplace.org/</A>) and further development of
|
|
endpoins is expected in upcoming months to make them adjusted to current
|
|
research directions of the group. However, all the blockchain
|
|
researchers are invited for cooperation and further development of Dru,
|
|
as well as to suggest any new endpoints we could implement. Any feedback
|
|
from the community is highly anticipated. We will be also promoting the
|
|
Dru platform at upcoming scientific events/conferences.
|
|
|
|
* - the name of the platform comes from the peak Aiguille du Dru in the
|
|
French Alps
