50p 2017

A conference about India's digital payments ecosystem.

After e-commerce, digital payments are again changing the way we buy and sell. As a developer you have a chance of building the app others will come to depend on.

HasGeek is organizing a new conference on the payments landscape, with a choice of topics bridging the gap between developers and business, merchants and buyers, and banks and regulators.

We are now accepting submissions around the theme of digital payments.

Suggested topics include:

  • Demystifying the payments landscape, specifically -
    • Legal
    • Regulatory
    • Transactional
    • Jargon
  • Foreign exchange
  • Cross-border funds transactions: what is legal, what is not?
  • New developments in the payment landscape like:
    • The Unified Payments Interface
      • Future course
      • Subscription billing
      • Split payments?
      • Operational guidelines
    • Payment banks
    • Wallets
    • Use of chatbots by wallets as interface with customers
    • Bitcoin and blockchain
      • Ethereum, etc.
    • AEPS (aadhar e-payment system)
    • International payments in India
  • Payments instruments
    • At Point of Sale (POS)
    • Remote
  • The smartphone as payment instrument:
    • Identity verification
    • Portability across platforms (Android, iOS)
    • Resilience under loss of access to network
    • Money transfer at POS (to a brick-and-mortar vendor)
  • Structure, implementation, and effects of the ongoing demonetization scheme
  • Workshops around open APIs from banks and PSPs


We are inviting proposals for:

Full-length 40 minute talks.
Crisp 15-minute talks.
Sponsored sessions, 15 minute duration (limited slots available; subject to editorial scrutiny and approval).
Hands-on Workshop sessions, 3 and 6 hour duration.

Selection process

Proposals will be filtered and shortlisted by an Editorial Panel. We urge you to add links to videos / slide decks when submitting proposals. This will help us understand your speaking experience, and if further practice is required. Blurbs or blog posts covering the relevance of a particular problem statement and how it is tackled will help the Editorial Panel better judge your proposals.

We expect you to submit an outline of your proposed talk – either in the form of a mind map or a text document or draft slides within two weeks of submitting your proposal.

We will notify you about the status of your proposal within three weeks of submission.

Selected speakers must participate in one or two rounds of rehearsals before the conference. This is mandatory and helps you to prepare well for the conference.

A speaker is NOT confirmed a slot unless we explicitly mention so in an email or over any other medium of communication.

There is only one speaker per session. Entry is free for selected speakers. As our budget is limited, we prefer speakers from locations closer home, but will do our best to cover for anyone exceptional. HasGeek will provide a grant to cover part of your travel and accommodation in Bangalore. Grants are limited and made available to speakers delivering full sessions (40 minutes or longer).


50p will be held at the MLR Convention Centre, JP Nagar.

Digital Cash - Cashless Economy Done Right

Submitted Jan 6, 2017

We often notice things only when its too late. The anonymity and freedom paper cash provides us is one such thing we seem to be forgetting.
We are transitioning into an era of digital payments using smartphones despite how vulnerable the smartphone ecosystem is and how trackable our lives become. Things are moving too fast, and getting this right is now or never.
We will see how we can tackle corruption by going digital with a better implementation that provides some other useful properties too.

I looked into various implementations including GNU Taler, Payse, Online Wallets, Cryptocurrencies,etc. but none of them get all of these right at the same time:

###Properties we need:

  • Security
  • Anonymity
  • Accountablity and Taxation
  • Offline and Online functionality
  • Transparerency
  • Convenience
  • Reliability

Basically imagine the best of both worlds: Cash and Cashless.

We can achieve this by introducing portable hardware wallets and digital cash that leverage on secure hardware and blockchain. We will discuss about unique identity management for people and businesses, wallet recovery, taxation, payer anonymity, reliability,etc. We will also discuss about potential attacks on the hardware to enable double spend, conterfeit digital currency,etc. and various implementations to thwart and contain such attacks that make this system viable.

I will open source the architecture and its specification for everyone to collaborate and improve. This has a long way to, but all I aim to achieve is establish a baseline and provide a better alternative to look forward to and work towards.



  • Why privacy matters
  • Debunking: “I’ve got nothing to hide, why should I care”

###Current Situation

  • Counterfeit notes and Corruption
  • Problems with BHIM and Mobile Wallets
  • Comparing existing alternatives for cashless economy
  • Potential National Security concerns

###The ideal Digital Cash

  • Properties we need
  • Why each one is important, and how it impacts us
  • The proposed system and how it achieves the above
  • How the system is Practical
  • Challenges we may face


  • The Vision
  • How to proceed


Basic knowledge on blockchain and Cryptography.
