Dear All, I would like to share an introductory video on Algorand protocol that I have recorded for the recently concluded India Dapp Fest. In this video we are talking about the main cryptographic and crypto-economic concepts powering this protocol.
It is a pragmatic protocol towards achieving #BlockchainScalability in a cost effective manner. It is leveraging randomness based algorithms ( that is why it is called ‘Algo-Rand’ in the place of famous and historic ‘Proof of Work’. It has constructed a ‘Pure Proof of stake’ using verifiable random functions (VRF). This protocol is a convergence of a lot of advanced engineering techniques like key management demon, REST based web services etc. It is designed by the inventor of #ZeroKnowledgeProof, Professor Silvio Micali himself.
We will share more details on Algorand in the coming days !! We have a digital community in India in Bengaluru. It is one of the first communities of Algorand in Asia itself. Looking forward to your active participation to contribute ideas, innovations and inventions in this community. You can find more about this community online : https://community.algorand.org/bengaluru/
Blockchain Scalability techniques and the scale cube metrics has made my Saturday morning live and loud ! I had the pleasure and privilege to take a live streaming webinar session on Blockchain Scalability – Architectures and Algorithms for the TechAthena community founded by technology leaders Shalaka Verma and Deepthi Annie.
During the initial interaction itself TechAthena community set their expectations clear. They are looking for a session on Blockchain technology beyond a product pitch or a corporate narrative. Hence I did a deep dive on Blockchain Scalability techniques from the vantage point of defining scalability of distributed systems with a specific focus on decentralised scaling.
I could lay out the most prominent Blockchain scalability techniques such as StateChannels, Sidechains, Offchain computation, Sharding, Replicated State Machines, Directed Acyclic Graphs, Gossip Protocols, variants of voting consensus algorithms, vertical and horizontal scaling etc. My presentation from this session is uploaded to SlideShare for further reviews and references. Request your thought and views.
During my preparations for the webinar, I could realise that fundamental postulates such as CAP theorem, Partial Synchronous processors etc. lay at the bottom of the Blockchain Scalability Constraints. It was a clear realisation that Consensus algorithms are not the bottlenecks in Blockchain scalability. Blockchain Trilemma coined by Vitalik Buterin underlined the need for factoring in Scalability trade offs in conjunction with decentralisation and security. I could easily comprehend the fact that in the contours of Blockchain, Decentralisation, Transparency and Scalability are the most important notions.
For a Blockchain evangelist, security and privacy gets redefined within the terrains of transparency. It is quite an interesting dimension. I could also connect with the scale cube defined in the book ‘Art of Scalability’ along with the Blockchain Scalability Trilemma and CAP theorem.
All together it was a great beginning to the weekend together with a network of hundred plus Blockchain evangelists. Thank you TechAthena community once again ! You can find the YouTube recording of the Webinar in the following channel. Request your views and thoughts.
I had an opportunity to talk about Blockchain Technology and its building blocks to the students and faculties of MCA department in Jain University in Bangalore.
It was a great experience to reflect on effective knowledge sharing strategies and pedagogic methods in the context of Blockchain technology. Students seem to have good awareness about the importance of cryptography in the Blockchain technology at the outset.
However, they are not well versed in the concepts like consensus algorithms, synchronous and asynchronous processes, time stamping, merkle tree etc. I could see that the history and emergence of Blockchain technology through CypherPunk and Cryptoanarchist community was not much exciting to them.
They were all attentive when I demonstrated Ganache UI and the Geth client. They were very curious when I demonstrated the use of Remix IDE and the Solidity syntax. All together it was a reflective and pedagogic experience to converse with young and ignited minds about Blockchain Technology.
It gives immense confidence, optimism and faith in our future generation and the possibilities and potentials of social entrepreneurship and social innovation in India when we get an opportunity to meet a knowledge collective of students who travelled more than 1000 kilometres from rural villages and emerging urban townships across Andhra Pradesh and Telangana, only to learn the fundamentals and applications of #BlockchainTechnology.
These young talents have immersed themselves in the finer nuances of Blockchain Technology and Decentralised business models to come up with a set of six product pitches and solution architectures working with mentors and experts from various Blockchain StartUps from across south India.
When we enter the realm of quantum computing from the theoretical foundations, we encounter the enchanting world of complex algebra and quantum physics. The symbols and notions may look quite bewildering for a software engineer. I have encountered this during my numerous sessions on Quantum Computing for Software Engineers and Enterprise Architects. Based on this experience, I have put together a collection of essential building blocks of a Quantum Computer from a few useful architectural diagrams. Most of these diagrams are quite accessible and available for everyone in the internet. I have organised them in a logical and structured manner. These diagrams provide a layer wise and component based view of Quantum Computing Architectures. This is presented recently in the Women Who Code #WWC #Bangalore Chapter MeetUp held in VMWare on November 2018 for an engaging and interactive audience.
Hedera Hashgraph is a Distributed Ledger Technology Platform formed by a consortium of companies leveraging the patented Hashgraph Technology for building distributed consensus based fair and ordered transaction systems. Hashgraph is a patented technology from SWIRLDS leveraging the concept of gossip to gossip protocols, virtual voting, replicated state machines etc. Please read further from my post in Quora.
