What you need to know about protocols and how to build your own open-source protocols Our world is on a fast track to incredible changes, especially in technology. As developers, we used to help build machines. Then we started building websites for businesses to represent them to a larger audience. Then we started building apps for every other product, sometimes more than one. In our new digital world, the next generation of developers won’t be building apps. We will be building protocols – middleware that enables decentralized applications (dApps) – and interfaces for the protocols. The world wide web is branching into decentralized networks and these networks will host countless protocols to play around with. This talk will cover how protocols work in decentralized networks, highlight a few important use-cases, and explain how to build your own open-source protocols on one of the most prominent DLTs of our times: IOTA.

1. Building Protocols for the new
digital world
Kumar Anirudha
Developer Advocate
IOTA Foundation

2. Protocol
A standard set of rules that
does a particular task.
- Networking/Communication Protocol
- Automation Protocol
...so on

3. Old Architecture
A classic API based architecture for a
web application.

4. Decentralised World

5. Rise of
Decentralised
Apps (dApps)
Decentralised Applications have made
the need for backend servers obsolete.

6. Rise of
Decentralised
Apps (dApps)
We already have an outburst of
web3 apps today on various
levels.

7. The web3
transition is
happening now!
Every industry is seeing a
disruption with the current
infrastructure rendered
obsolete.

8. Closed vs Open Infrastructure
With Closed Infrastructure, we are made
to rely on the platform and services
provided by the proprietary software or
hardware vendor.
With Open Infrastructure, we can choose
what to use and rely on. We can have
others help out with any action or update
and build a collective environment via
open source protocols.

9. Black Box
Infrastructure is
outdated
We can’t rely anymore on services
which asks us to blindly trust their
metrics, algorithms and systems.
Even the Audits done on Enterprise Infrastructure
isn’t reliable.
Lot of trust issues have risen in recent years
starting with Facebook, and other similar
enterprises using data for anything and everything.

10. Insane amount of interconnected devices

11. Interoperability is a huge issue with more backend servers running. No single platform can support everything.

12. Open Protocols for
web3
The only way to build a sustainable
ecosystem for the next generation
infrastructure is to build it open source.
Anybody can contribute to it and we can
build together. We don’t need 100
different lighting solutions. We need 1
solutions built by 100 brilliant minds
which is just perfect.
There is no need for backend servers
anymore. Smart Contracts can run
protocols on the decentralised network
and we can all share, improve or build on
it.

13. Build protocols on
DLTs
Smart Contract Infrastructures like IOTA
Smart Contracts has enabled us to build
protocols or dApps right now.
Decentralised Identity for Authorisation
and Authentication.
All business logic in Smart
Contracts.

14. Decentralised
Identity
No need for 3rd party
verifications and
authorisations.

15. IOTA Smart Contracts Architecture
We need a free and open web to
build and share on.
Interact with other protocols,
services and devices.
We need to make this open
source so it builds that trust on
our protocol which doesn’t exist
in the current industry.
Build and run parallel sharded
chains for your own use-case
and interoperate with others
running their own chains.

16. Open Source
Protocols is the future
of the new digital
world infrastructure.
