Smart Contracts Blockchain has the potential to transform conventional industries and business operations. Traditional agreements require a third party in a centralized system to execute agreements between parties. Contrary, smart contracts automate agreement execution eradicating third party’s intervention. These contracts are stored, modified in a blockchain that adds security and privacy there.
What do Smart Contracts Bring?
As smart contracts are based on blockchain, they bring multiple benefits with them. Some of them are:
Autonomy and savings
Smart contracts blockchain does not need brokers to execute the agreement; it eradicates the manipulation risks. Moreover, the decentralization results in cost and time savings.
Backup
The duplication of contract data on multiple nodes makes it easier to restore original data in the case of any data loss.
Safety
The encrypted and cryptographic nature of smart contracts makes all the documents protected from infiltration.
Accuracy
Manual filling of multiple forms can cause numerous errors. So, smart contracts are the best solution to achieve accuracy.
Smart Contracts Blockchain Applications
Smart contracts blockchain has multiple applications in multiple fields ranging from health care to financial services. The most prominent applications are:
Government voting system
Smart contracts offer a secure atmosphere that makes the voting system impossible to manipulate. The votes through smarts contracts are ledger protected, hard to decode. Moreover, smart contracts have enough potential to increase voter turnover that is low due to an inefficient system.
Healthcare
Blockchain stores the encoded patient records using private keys where only specified people can have access to records. In addition to this, smart contracts make research confidential and secure.
Hospitals can store patient receipts on blockchain that are shareable with insurance companies as proof. Moreover, health organizations can use hyper ledgers to manage drug supplies, supervision and regulations.
Supply chain
The supply chain usually suffers due to paperwork, as every document has to pass through numerous channels to get approval. As a result, the ratio of frauds increases in supply chain networks. The blockchain nullifies those risks offering accessible and secure digital versions in the form of smart contracts. Smart contracts automate the process and make inventory management easier.
Financial services
Blockchain smart contracts transfer the traditional financial sector in multiple ways. For insurance claims, they check errors, routes and initiate transactions if everything is appropriate.
The smart contract incorporates tools for keeping records and eliminating infiltrations. Contracts also authorize stakeholders to participate in decision-making transparently and make trade clearance easier.
Challenges of Smart Contracts
Difficult to Change
Smart contracts are impossible to changes once developed. Any error in the code can be time-consuming and expensive to handle. As smart contracts are usually created against a huge amount, any coding error may cause a big financial disaster for concerned parties.
Possibility of Loopholes
As the good faith concept illustrates, parties have to deal fairly, and no one can have unethical benefits from smart contract blockchain. However, it is difficult to ensure that all agreed terms are met.
Vague terms
Smart contracts include terms that are not easy to understand which makes it difficult to handle vague terms and conditions.
Third-party
Although smart contracts eradicate third-party involvement, it’s impossible. Here, third parties are different from traditional ones. For instance, developers will need to consult with lawyers to understand the terms and conditions.

Join us on Sunday 4 October for a workshop that introduces the various concepts, techniques and methods behind the False Positive project. Topics include an overview of setting up open source cellular networks, working with APIs for data mining and profiling using social media, and designing corporate fictions for social interventions. Take part in a CryptoParty - www.cryptoparty.in - where you can learn best practices for digital security, including how to use basic cryptography tools. Interested in working with the Tor anonymity network, public key encryption (PGP/GPG), and OTR (Off The Record messaging)? Bring your mobile phone and/or laptop, and we’ll get you set up and on your way to a more secure online existence.

Un criptograma es un mensaje cifrado cuyo significado resulta ininteligible hasta que no es descifrado.
Generalmente, el contenido del mensaje es modificado siguiendo un determinado patrón, de manera que sólo es posible comprender el significado original tras conocer el patrón seguido en el cifrado.
Cryptography is the practice and study of hiding information. In modern times, cryptography is considered to be a branch of both mathematics and computer science, and is affiliated closely with information theory, computer security, and engineering.
Understanding blockchain technology is important to grasping the total concept of cryptocurrency in general. The blockchain can be thought of as an online peer-to-peer digital ledger that keeps track of cryptocurrency user balances by tracking & evaluating the transactions. In this sense, a...

This photograph was taken whilst on a trip to Manchester a few years ago visiting my girlfriend. We often went to the Whitworth gallery nearby, this time a trip around the gallery was followed by a wander around the gardens, what had always been somewhere simply to get from one place to another through was augmented through time, and a contemplative aura. The facelessness of the statue evoked a sense of memorandum. In combination, this atmosphere, and the starkness of the brightness of the day generated the inspiration to freeze this moment in simple imagistic representation; and now cryptographically.

Whitfield Diffie gives William Gould Dow Distinguished Lecture titled: Post-Quantum Cryptography in Context at Stamps Auditorium on University of Michigan North Campus.
Whitfield Diffie is best known for his discovery of the concept of public-key cryptography, which he developed jointly with Martin Hellman at Stanford University in the mid-1970s. The two shared the ACM Turing Award in 2015 for work that “made cryptography scalable to the Internet and revolutionized the landscape of security.” Retired from positions as head of security for the Canadian telephone system and Sun Microsystems, Diffie is now an Honorary Fellow of Gonville and Caius College in Cambridge. He is a member of the National Academy of Engineering, the Royal Society, and NSA’s Cryptologic Hall of Honor.

A typical Typex Mark 22 which was used during WWII. It is an adaption of the standard Typex Mark II and was used for many years after the war was over.
The Mark 22/23 shown here was modified to increase its security and to make it compatible with the German military Enigma machine. Once the German messages were broken with help of the Bombe machines, the intercepted messages were decrypted manually using these machines.
Typex Mark 23
The modified Typex Mark 22 (BID/08/2), appeared relatively late in the war and had an extra plugboard at either side of the keyboard. Compared to Enigma, the standard plugboard was more versatile as it allowed each letter to be swapped with every other letter, rather than swapping them in pairs like on Enigma. Some Mark 22 machines were later modified into a Combined Cipher Machine (CCM), to allow the British to exchange secure messages with the Americans.
