Blockchain Smart Contracts Community

|

I would like to see a Community on Blockchain and Smart Contracts  What is your opinion?   I also see a number of posts in this area but not much participation.  I see views but not much in the way of feedback and returning comment on a blog.   As an example, I had a recent blog that had over 1000 views with not one comment! This is how we learn and build our knowledge.   Participation and exchange of ideas.  I am probably also guilty of this.  Yes I am. Cheers, -Dale Montrone ‌ ‌ ‌ 

Blockchain Powered Smart Grid Evolution

|

In economic terms, electricity (both power and energy) is a commodity capable of being bought, sold, and traded. [1] An electricity market is a system enabling purchases and short-term trades, generally in the form of financial or obligation swaps. Bids and offers use supply and demand principles to set the price.  Transactions (bids and offers) in electricity are typically cleared and settled by the “market operator” or a special-purpose independent entity charged exclusively with that function such as an Independent System Operator (ISO).   Let us illustrate the function of a typical ISO like the one in the State of New York in the USA. [2]  It’s mission is to reliably manage New York’s power grid and energy markets consisting of 11,000 circuit miles of transmission lines.  Their members...

Blockchain

|

In simple words, data are contained inside blocks as well as an arbitrary integer that is necessary for producing the proof-of-work. In bitcoin blockchain, the block contains a header and relevant transaction data. A merkle tree of transactions is created and the hash of the root is included in the header. A merkle tree is a full binary tree of a hash values. At the bottom level of the tree, each transaction has a node containing its hash value. After that, the tree is constructed in a way such that the parent node has a value of the hash of the data contained in its children concatenating together. The blockchain is designed in a way such that the average time for a block to be generated remains fairly constant. In the bitcoin blockchain, the average time for a block to generate is 10 min...

Blockchain Powered Smart Contracts for Internet of Things (IoT) Applications

|

Blockchain is far more widely useful than for just cryptocurrencies such as Bitcoin.  Blockchains create immutable, persistent, and searchable records of events, transactions, contracts, and official documents. If we think beyond the realm of humans interacting with each other and look forward to the new world of autonomous systems interacting with each other, blockchain technology gives us a simple, cost-effective, and permanent record of decisions made and communicated on our behalf. [1] An example of a IoT network is exemplified by the figure above, which illustrates how Internet of Things nodes can be managed by a server or a set of servers. This diagram explains the possible topology of an IoT network. [2] Referring to the figure, part of the management software resides in the Aggrega...

What happens when you fuse AI & Blockchain

|

First, there was AI and then came Blockchain, so what’s next? – the amalgamation of these two brilliant technologies to create something more revolutionary. The time has come for businesses big and small to progress with an open mind, to try out all the new ideas and the new trends that technology is bringing. There is a thin line between developing FOMO (fear of missing out) and being thirsty to learn more and try new stuff. AI and Blockchain are both such powerful technologies and this is why the killer combination of both would result in some great results. Blockchain needs efficient data extraction which AI can perform and AI needs extensive data which Blockchain can supply. Undoubtedly they can both impact each other and together impact the businesses.  Leave it to the Machines! Block...

Fidelity’s Proof of Work: Our Bitcoin and Blockchain Journey

|

This article is authored by Hadley Stern, SVP and Managing Director at Fidelity Labs. He is responsible for Fidelity’s blockchain and digital asset incubator.  For nearly four years, I have been deeply involved in our exploration of Bitcoin and blockchain technology at Fidelity Investments. Our interest began in 2014, and has grown into a dedicated team that is researching and experimenting across different parts of our business. Our journey is an exciting one. It has been difficult at times for me, but I have grown through the people I’ve met and the discoveries we have uncovered along the way. It can be daunting for me or any member of our team to take on a new challenge that is uniquely complex, specifically in an area that remains largely misunderstood. We used a three-step approach th...

Blockchain Powered Smart Contracts: Ethereum vs Hyperledger

|

In a “Smart Contract”, the terms of the agreement between two contracting parties or entities are directly written into lines of software code using a programming language like C or Solidity [1].Such a Contract is generally  executable meaning that the adjudication process is automated based on the terms embodied in the software code and the enforcement is controlled and carried out by the software code itself. A Smart Contract typically runs on a private or public Blockchain Platform. Examples of such platforms are Hyperledger [2] and Ethereum [3]. Hyperledger[4] is an open source collaborative effort created to advance cross-industry blockchain technologies. It is a global collaboration, hosted by The Linux Foundation, including leaders in finance, banking, Internet of Things, supply cha...

Nasscom Blockchain SIG’s Blockchain Tech Bootcamp- Post event Roundup

|

Nasscom Blockchain SIG’s Blockchain Tech Bootcamp had over 150 participants in attendance. The event began with a welcome address by Mr. Gulati of Hartron who briefed everyone about Hartron and the Innovation Campus it hosts within the campus in association with Nasscom and Nasscom’s 10K Startups program. Rajesh Dhuddu, Nasscom Blockchain SIG Chair presented the evolution of Blockchain covering Cypherpunk and Crytoanarchy movement, contribution by Tim C May and Wei Dai through his Bmoney protocol. He explained how Satoshi Nakamoto assembled all these along with Adam Back’s Proof of Work concept and proposed Bitcoin and underlying protocol in his whitepaper. Rajesh also covered SHA 256 algorithm, hashes, blocks, nonce and merkle tree.   This was followed by practical demo session by Jaffer ...

Blockchain Powered Digital Contract: Executable Vs. Non-executable

|

In a “Digital Contract”, the terms of the agreement between two contracting parties or entities is directly written into lines of software code using a programming language like C or Solidity [1]. A digital contract can be executable or non-executable.  The non-executable contract is nothing more than a software version of a contract written in a spoken language like English.  The advantage is that it can be verified using a simulator and “what if” scenarios can be investigated.  The enforcement of a non-executable digital contract needs to be done manually, as is the case currently with contracts written in spoken language.  However, the advantage is that a digital contract is easy to write, edit and verify using a simulator and lends itself to playing “what if” scenarios either before th...
