Special Issue On Blockchain Technology And Applications



Blockchain has the potential to revolutionize everything from voting to stock trader. The first major application of blockchain technology was bitcoin which was released in 2009. Understanding how a blockchain works from a technical point of view, is valuable only to the extent of developing or troubleshooting one. They validate all the transactions and only once its timestamped by a notary can it be included in the immutable chain.

The Bitcoin network orders transaction by putting them together into groups called blocks, each block contains a definite amount of transactions and a link to the previous block. After the copy has been downloaded, the node can then run-independently to process transactions and propagate them further across the network.

A block is the ‘current' part of a blockchain, which records some or all of the recent transactions. Transactions occur between blockchain addresses. The current focus in the media on the cryptocurrency element of blockchain has taken away a fair amount of attention away from the underlying technology.

This was the root of every other cryptocurrency and latest versions of blockchain technology. One digital key ensures only you can enter a transaction to the blockchain involving your assets, and another digital key lets someone else confirm it really was you who added the transaction.

It provides a Nakamoto consensus” algorithm called PoET (Proof of Elapsed Time) which can be executed in a Trusted Execution Environment (TEE) such as Intel® Software Guard Extensions (SGX) In a way, the principle is similar to that of Bitcoin, wherein the first validator to win the lottery” (in case of Bitcoin, solving a cryptographic puzzle) propagates the block.

Microsoft Corporation ( MSFT ) has also expressed interest in blockchain technology, having recently formed a partnership with blockchain firm ConsenSys. While there's a lot of research going on in companies, universities need to step up their efforts in research as well as in offering programs to train the next generation of blockchain developers and entrepreneurs, he says.

Overstock CEO Patrick Byrne has called t0 a blockchain version of Wall Street, and in a Q&A with PCMag, the outspoken executive talked about how the platform works, making history with t0, and how blockchain could turn capital markets into Game of Thrones.

Policymakers should endeavor to understand blockchain technology, support the development of blockchain standards in the electricity sector, and allow innovation to flourish by setting up regulatory sandboxes that permit demonstration projects. Other potential applications include using blockchain to provide massive scale data authentication.

No one needs any permission to participate in the public blockchain or query about it. Any transaction process through this kind of blockchain is validated for all. Conditions of smart contracts are mutually agreed on by network members. Sometimes, we can say that the block time is the time required by the blockchain miners to find a solution to the block hash.

Blockchain could inject new options into that dynamic: with a blockchain identity solution distributed ledger, drivers and riders could create a more user-driven, value-oriented marketplace. For these reasons, permissioned blockchains are expected to be adopted by business organizations such as financial institutions.

ProofofExistence one of the first non-financial companies to utilize blockchains, is a platform for executing contracts. As a digitized, secure, and tamper-proof ledger, blockchain could serve the same function, injecting enhanced accuracy and information-sharing into the financial services ecosystem.
