This time we have a four fold agenda. The talk will consist of: --> The need for better user experiences continues to push functionality into the browser, and many back-end services become thinner and less complex as a result. --> While organizations continue to mature in their use of cloud technologies, an inevitable creeping complexity always accompanies building real solutions with these new pieces. --> We see a shift in the traditional 'lock everything down globally' approach to a more nuanced, localized approach. We welcome this shift, especially when tools and automation can ensure equal or better compliance. --> The Internet of Things (IoT) ecosystem continues to evolve at a steady and strong pace and includes critical success factors such as security and maturing engineering practices.

1. Blockchain beyond Bitcoin
Sreedhar Joshi

2. What I intend to cover
● Why is the buzz around blockchain in the recent times?
● What are some of the misconceptions prevalent about Blockchain?
● I'm new to crypto world , What if I don't care what Block chain or a crypto currency is ?
● What are bitcoins?
● What are pros and cons if a country supports a crypto based payments?
● What is the scope of Blockchain?
● Business scenarios where Blockchain has been used or can be used?
● Is it all about cryptocurrencies or what are other platforms in which I can implement it in?
● What are areas where it is used, advantages and alternatives?
● What are some applications that are using blockchains unnecessarily though there are better solutions? Do we
know when to not use blockchains?
● How do we deal with the explosion in the number of cryptocurrencies and their abuse in pump and dump schemes
and fake ICOs?

3. What I intend to cover (contd..)
● Are there any existing real-time applications of Blockchain other than cryptocurrencies and as an upcoming
developer how can I use/implement blockchain.
● If I were to start a project that requires a blockchain today, what open-source implementations are available?
Hyperledger isn't here yet. How can we take up any blockchain projects without implementing a new blockchain
from scratch?
● As a I am part of tech industry what are things i should know and learn.
● How is blockchain different (both advantages / disadvantages) from other distributed technologies.
● Why is mining becoming resource/power consumption overhead, what alternatives?
● What is blockchain? Technical breakdown of concept and implementation.
