Django Blockchained

Saturday: 11:30 - 13:30

Workshop leader: Sylvain Bellemare

As a backend developer, working with Django, a relational database
(e.g. PostgreSQL), an asynchronous task queuing system (e.g.: celery/RabbitMQ),
a cache system (e.g.: redis), a search engine (e.g.: elasticsearch), do I need
to care about some of the hype surrounding blockchains?

What is a blockchain anyway?

What is the difference between the bitcoin blockchain and other blockchains?

Does a blockchain imply a cryptocurrency?

Could I use a blockchain to manage transactions that do not involve money?

What do terms such as "distributed", "decentralized", "immutability",
"consensus", "byzantine fault-tolerant", "public ledger" mean in the context of

What kinds of django applications could benefit from using a blockchain?

The proposed workshop wishes to look at how a "traditional" web stack powered
by Django could benefit from using blockchain databases in addition to
relational databases, search engines, caches, etc.

The workshop wishes be very developer oriented in the sense that developers
who work on web stacks that involve Django and the commonly found storage
systems, such as PostgreSQL can explore new possibilities that blockchain
databases could possibly open up.

In a similar way that elasticsearch may have made its way into a web stack,
alongside with PostgreSQL, a blockchain database could potentially join the

Taking the wishes of the audience into consideration, the workshop will include
a substantial amount of hands-on examples with python libraries that can be used to
interact with the bitcoin blockchain, such as transactions (,
as well as a python library that demonstrates a usage of the bitcoin blockchain to manage ownership
of digital property -- pyspool (

These hands-on examples could then be useful for those who sprint on some blockchain-related project.
