Why We Need a Public Blockchain with Key-Value Pairs?

Today we are well aware of the fact that blockchain technology offers data authentication and authorisation in the digital world, abolishing the need for third-party administration. Also, the numerous features of blockchain such as data security, reliability and the robustness have played an essential role in the boom of blockchain technology. As organisations are keen to implement blockchain for various applications, one must make an informed decision while choosing the right kind of blockchain.

Private Blockchain or Public Blockchain

When it comes to the blockchain, there are three types of the blockchain, private blockchain, public blockchain and consortium blockchain. As distribution is one of the principal features of blockchain technology, a private blockchain may not be truly distributed as it is a closed network. Private blockchains take advantage of blockchain technology by setting up groups and participants authorised to verify transactions internally. The developers of that particular blockchain control the extent to which each participant can have read and write permissions. This puts the concept of private blockchain under question.

Whereas in the public blockchains such as RecordsKeeper, they are based on complex consensus algorithms. The public blockchain is open source and not permissioned. Anyone willing to participate can download the code and start running a public node on their local device/server, Miners can validate transactions in the network, thus participating in the consensus process. Anyone in the world can send valid transactions through the network, with the freedom of reading transaction on the public block explorer as transactions are transparent.

Public Blockchain such as RecordKeeper, being distributed is one of the many major features. However, this is not the only benefit of  RecordsKeeper of course. Other features such as transparency make RecordsKeeper very secure: as data can be audited by anyone, it is easy to detect fraud on the chain. With public blockchain such as RecordsKeeper, you have the flexibility to set it up in your local infrastructure or cloud, or you can use RecordsKeeper ready-made public blockchain which provides features such as data immutability, data integrity, data authenticity and data verifiability.

RecordsKeeper has overcome many limitations of certain popular blockchains such as Ethereum by making the block size of 10MB instead of 1MB. RecordsKeeper maintains a mining diversity of factor 0.2 thus keeping 51% chance of attack under the tab. If there are 200 miners in the community and a miner mines a new block, he/she will have to wait for 40 blocks to be mined before he/she can mine another one following the mining diversity of 0.2. Therefore miners are refrained from mining a continuous series of blocks, limiting them from overpowering the Blockchain.

Why Key-value pairs?

RecordsKeeper lets you submit the records through your web interface or via the RecordsKeeper’s APIs, and publishes the records in key-value pair format with their associated information into a decentralised ledger.

Being an open source, public blockchain network that stores information in key-value pairs, RecordsKeeper has proved to be an excellent choice by many organisations for various applications. Data stored in Key-value pairs provides ease of querying the data unlike other public blockchains such as ethereum and Bitcoin. Data can be easily traced and retrieved anytime by the corresponding key.

Applications running on the RecordsKeeper Public Blockchain

RecordsKeeper has enabled organisations to optimise the supply chain management by ensuring seamless operations such as recording the quantity and transfer of assets, tracking purchase orders, change orders assigning or verifying certifications and more. RecordsKeeper maintains transparency by recording the current status of the supply and its related compliance in the ledger. RecordsKeeper lets businesses set the rules for recording the data so that they can set the compliance conditions themselves.  RecordsKeeper ensures the data to be shared meets the compliance conditions.

Organisations are using RecordsKeeper to store corporate compliances. As organisations primarily seek data immutability feature while storing corporate compliances, RecordsKeeper has proved to be an ideal choice. Not only the data saved over  RecordsKeeper blockchain becomes immutable, but it also let the organisations monitor regulatory feeds and update their records according to the pre-set regulations in the RecordsKeeper blockchain.

RecordsKeeper has successfully overcome issues insurance companies were facing such as Data Security, Fraudulent information, Trust issues. The distributed nature of RecordsKeeper has ensured data security and build trust. As the data stored on RecordsKeeper becomes Immutable, chances of fraud are obsolete. By providing added security and the ability to establish trust between entities RecordsKeeper has helped in solving the interoperability problem.

Conclusion

Public blockchain network with key-value pairs such as RecordsKeeper, offering exceptional features are indeed the need of the hour in blockchain technology.

Scams on Blockchain and How to Outsmart Them

Last year, Blockchain came into the spotlight. The potential of the blockchain investor excited a general investor about the future. Unfortunately, every time something pathbreaking (like blockchain) comes into the picture, there are always con artists waiting for their next opportunity to scam the innocents.

Understanding the most common types of scam on Blockchain is essential to ensure that consumers don’t fall prey to tricksters. Most scams have clear warning signs, and just by being aware investments can be protected.

Below we talk about some of the common scams plaguing the blockchain, and ways to outsmart them.

Is your Hardware Wallet safe?

Most people agree that hardware wallet for storing cryptocurrency is enhanced security and privacy. However, if a consumer is not careful about purchasing the wallet from a trusted source — there can be potential vulnerabilities. Hackers can pre-built specific hacking algorithms into the hardware wallet. This opens up the wallet to hackers, and they can easily steal the cryptocurrencies. This type of scam is becoming more and more common. However, you can avoid it by purchasing a wallet from only a trusted and verifiable source.

Scams on Exchanges

Ironically, despite cryptocurrencies inbuilt decentralized nature, most of them are traded over exchanges. Most exchanges make lives of consumers easy by giving access to multiple cryptocurrencies at one place. The fact of the matter is also that governments do not govern most of these exchanges in most countries. Thus, the potential for scam multiplies if the consumer is not careful. It takes no complex algorithms to spot exchange scams. However, if you overlook the visible red flags — then you’re in for big trouble. The most common way to spot a scam is when an exchange is offering a massive discount on one or more than one cryptocurrency. This technique is usually a trap to lure everyday investor. Another way to confirm whether an exchange is authentic or not is by looking at its URLs certification and undertaking research.

Scams through ICO’s

Along with the word ‘Bitcoin’ and ‘Blockchain’, investors have also been hearing the term ‘ICO’. ICO stands for the initial coin offering. Through ICO,  companies can raise capital for their unique ideas and projects. The popularity, however, also gives rise to people and organizations looking to cheat first-time investors. One way in which ICO scams take place is through the creation of fake websites for users to deposit coins. The bigger scams under ICO, however, take place when a group of people come together to create an organization to scam. There have been several cases like that in 2017 and before. As a rule of thumb, you should not invest in an ICO until you’ve done significant research about the organization. Don’t forget to give a thorough read to their white paper along with reading up on their team and other investors.

Fake Schemes Concerning Cloud Mining

A lot of companies these days are coming up with schemes that give outstanding returns once you rent a server to mine any cryptocurrency. Since the mining activity is unique and is known to be resource-intensive, the difficulty of mining cryptocurrency is significantly high. Most of these companies make fake bold claims about returns to scam the general public. Some even operate as a ponzi scheme right from the start. Before associating with mining cryptocurrency as an activity, it’s paramount to do intensive research.

Conclusion:

Blockchain and cryptocurrencies have a long way to go, and their potential is just being realized. As the days pass, both transparency and security in Blockchain are bound to be better. All investors should be aware of the common scams on the blockchain and the ways to avoid them.

Trusting Blockchain exchange

With every passing week, the world’s interest in Cryptocurrencies is multiplying at a staggering rate. Whether it’s bitcoin, ether, or any any other cryptocurrency on the block – people around the world own and trade cryptocurrencies. To make the trading accessible to the general public, we’ve several cryptocurrency exchanges on the world wide web. Through these exchanges, anyone can buy, sell, or exchange cryptocurrencies either with other digital-based currencies or with traditional currency such as rupee or US dollar.

Types of Exchanges

There are three categories of cryptocurrency exchanges. They’re as follows:

Brokers – Through these brokers, anyone can go and buy the desired cryptocurrency at a preset price. Most of these cryptocurrency brokers are similar in function as foreign currency exchanges.

Platforms for Trading – These platforms specialize in connecting buyers and sellers. For every transaction that takes place through the platform, they charge a fee — which is also how they make money.

Direct Trading – The way direct trading differs from the other two is that there’s no fixed price. The seller decides the amount, and the buyers have to determine if they want to buy or negotiate for any particular cryptocurrency. Direct trading is usually peer-to-peer.

What are the key attributes to look at while deciding to Trust a blockchain exchange?

The meteoric rise of bitcoin has also contributed to a significant increase in con-artists and exchanges which are mostly scams. So, before you decide to put your hard-earned money to buy cryptocurrencies — it is crucial to do your research. Below are the three things to know about an exchange before trusting them.

Reputation: In the age of the Internet, it’s not too hard to find reputable reviews about anything — including blockchain exchanges. Right from forums to commercially reviewed websites, you’ll find loads of information that’ll make it easier for you to decide whether an exchange is a right fit for you or not.

Fees: Before you even think about joining an exchange, do make sure you’re well-aware of all forms of costs that the exchange charges. The fee-model should include comprehensive details regarding withdrawal, deposit, as well as transactional fees. Compare it with other exchanges and then make an informed decision.

Verification systems: Any exchange worth its salt will have strong fortification in the form user verifications and securities. While the exhaustiveness of the verification might seem annoying while registering, it’ll protect your cryptocurrency and money from all sorts of scams.

Some well-known and reputable exchanges

We’ll make it even easier for you. Based on our research and user reviews, we’re going to tell you our favorite two blockchain exchanges that you can trust without worry.

Coinsquare: The first thing you should know about coinsquare is that it’s built on the same technology as the New York Stock Exchange. Yes, that’s right. According to their website, they manage their ledger at least 2346 times in a single day to ensure security. Reputable and secured, Coinsquare is a popular choice for both crypto-veterans and beginners alike.

Coinbase: Not only is Coinbase backed by some of the world’s best investors, but it’s also trusted as an exchange by millions already. One of the key features of coinbase is that coinbase insurance covers the stored currency. So, there’s that added layer of security. There’s a digital wallet also available as a mobile platform through which users purchase bitcoin, ether, and even litecoin.

Discovering Blockchain Loopholes

There’s no doubt on the potential that the blockchain technology has to offer. The world has accepted it at large. Blockchain developers are solving multiple problems across industries with this technology.

But there’s another side to the story wherein the hype is shadowing real implementation issues with the blockchain. These issues hinder the mass-adoption of this world-changing technology.

There’s no doubt that we’ll eventually get to the point wherein we’ve explored this great technology. However, to be able to that it’s essential to face realities both as developers and enthusiasts of the blockchain.  

Below we’ll be mentioning four implementation issues that plague blockchain as of today.

Limited Scalability –

One of the key advantages of the blockchain technology is decentralization. However, it comes at the cost scalability. As the number of transactions increase (and since every transaction passes through each block), the requirement increases too. Eventually, it’s not possible for every node to participate and the resources to process each block then rests with a limited few. However, that potentially compromises on the decentralization aspect of the blockchain. Scalability is probably the number one barrier when it comes to blockchain adaptability.


Storage Constraints –

Almost every application that’s built on the blockchain will require some form of storage. It can be either to store user identities, or it can be to record specific financial as well legal data. However, by property traits, every node stores the data. Along with it, no data will be able to be removed regardless of whether it’s needed or not. The above two cases put a considerable cost to the storage operation when it comes to the blockchain. Thus, storage constraint is a massive hurdle for any application to be able to build on the blockchain.


Lack of standards and governance –

No central authority governs public blockchain. While that’s great to build a trustless and open, it has its disadvantages. First, one is that there’s no who’s responsible for maintaining and upgrading the systems most efficiently. Even if some developers band up to create an organization, it leads to some form of centralization (take the instance of the Ethereum foundation.) However, we can’t even leave it completely open as over the years it’s proven ineffective on multiple levels.


Poverty in Available Tooling –

For any developer to work effectively and efficiently, the first requirement is adequate tooling. If inadequate, the developers can’t do much even with the best of the intentions. As a matter of factor, the currently available pool of tooling is not good enough, even for the most seasoned of the developers. Right from good testing frameworks to security auditing and even right blockchain analytical tool — the available tooling to a blockchain developer is severely limited. Along with hindering the potential of the technology, it also demotivates enthusiasts.

Conclusion:

Unfortunately, the hype makes blockchain appear invincible when the fact is that there’s a lot of work left. So, instead of making the technology glamorous, we need to focus on how to solve core implementation issues with the blockchain.

There’s not even an iota of doubt that blockchain is here to stay. However, the issues mentioned above and many more are not letting the technology become mainstream. It’s on us now — the developers, the investors, the blockchain enthusiasts — to work towards a unified vision.

POI vs POW vs POS

Being involved in the world of blockchain and cryptocurrency means that you’ll regularly come across algorithmic terms. Primarily, there are three types of algorithms used for cryptocurrency projects:
  • POW (Proof-of-Work)
  • POS (Proof-of-Stake)
  • POI (Proof-of-Importance)
While deciding for whether to invest in a cryptocurrency project or not, one of the decisive factors to consider should be the algorithm it’s based on. Below we’ll be mentioning the critical pointers of each of these terms along with what separates one from the other.

Proof-of-Work (POW)

Satoshi Nakamoto, the creator of Bitcoin, pioneered the Proof-of-Work as a mechanism. After which many cryptocurrencies, including Ethereum, based their network on the same algorithm. The computers involved in maintaining the security of the network work to solve a mathematical puzzle known as a hash. Although the task is quite straightforward for a computer, it’s intensely repetitive. Thus, it requires exceptional computation power. Therefore, proving that they’ve done the necessary ‘work’ to register a data block into the network.  In the recent years, the POW algorithm has been criticised because of the high initial investment and the environmental cost attached to it. The POW, theoretically, is also prone to what is known as the 51% attack. It’s a situation wherein a miner controls more 51% of the computational power of a network and thus can change the data within each block.

Proof-of-Stake (POS)

The tremendous amount of computational power required makes POW both expensive and energy-intensive. An alternative algorithm — Proof-of-Stake — has gained popularity in the recent years. Unlike POW, the POS approach requires no specialized hardware in-order to participate in the network. POS takes the path of letting the coin stake of a particular user determine the likelihood of them adding the next block of transactions to the blockchain. To influence the network fraudulently, a person will have to own 50 percent of the coins on the network. An attempt to buy such an amount will exorbitantly push the price up; thus rendering the entire effort futile. NxT pioneered the POS system. Nowadays, this algorithmic approach is often used by crowdsale-funded platforms, wherein tokens are distributed based on investments made.

Proof-of-Importance (POI)

With POI, the dependency is neither on the amount of ‘work’ nor the amount of ‘stake’ you hold. POI, as an algorithm, takes a more holistic approach to considering the overall productivity of a user in the network. The reward, as per POI approach, should be based on the contribution of a user to the network in all capacities. The staking of the block, therefore, is based on multiple factors including reputation, overall balance, and the number of transactions done through or from a particular address. Through these factors, the network determines how ‘useful’ the member is to the network. NEM was the first cryptocurrency project to implement POI as an algorithm to its platform. Increasingly, people are finding ways and combinations of both POS and POW with POI to create an algorithm that makes it tremendously expensive to attack the network but rewards those who protect it generously.

Press Release: RecordsKeeper – An Open Public Ecosystem for Record Keeping & Data Security

Last few years turned the spotlight onto the Blockchain Technology, and the rest, as they say, is history in the making. Right from basics, everyday financial decisions to unprecedented social and economic impact, we believe that Blockchain has what it takes to change how the world functions.

However, experts believe that the full potential of the incredible Blockchain Technology isn’t yet explored. With every passing day, new use-cases are emerging for Blockchain Technology. Every industry is solving old-age problems or making the entire system more efficient with the help of the Blockchain. But the surface has barely been scratched when it comes to the massive impact.

With the same belief, we are happy to announce, RecordsKeeper – an Open Public Ecosystem (with Mine-able Blockchain) for Record Keeping & Data Security.

How RecordsKeeper Blockchain Can Help in Preventing CBSE Exam Leak

Recently we came across a major story about the CBSE paper leak from various sources. Those who had access to the exam papers charged Rs. 35,000 per paper and even some parents took part in it by reselling the papers to others to cover their cost. Thus the leaked papers were available upto Rs. 5,000.

This caused a huge uproar among the students which led to a re-examination. The current investigation is currently focusing on the role of CBSE officials, invigilators and school staff, coaching centres and printers. The leaked Economics paper was being circulated on social media for several hours before the test started on Monday. The Delhi government also reported that it received complaints from the CBSE about the Class 12 Accountancy paper being leaked too.

The past months saw many downs for the education system in India and challenged the way we share information in our country. This whole fiasco could had been resolved if the education system was driven by the power of Cryptography and Blockchain. We at RecordsKeeper thrives on latest technology and the power of Blockchain. This specific use case is the prime example of where RecordsKeeper comes into play and provide the utmost security in the shared information world.

RecordsKeeper: What is it?

RecordsKeeper is an open source platform for open record keeping & data security. Using RecordsKeeper’s public Blockchain anyone can publish a key-value pair of records which are immutable & verifiable.

Let’s discuss some of the major problems and how RecordsKeeper can solve them with respect to the CBSE paper leak.

  • Multiple mediums present for the exam paper

Currently the CBSE paper is presented in multiple mediums which gives a person with authority to take it out and sell over the black market without being noticed. Using RecordsKeeper as the storing medium for the exam papers, it limits the exam paper presence on multiple mediums. Once the exam paper is over RecordsKeeper Blockchain then there is only one single medium of shared ledger available.

  • Hacking of central storage

If the CBSE exam is shared over some relational Database or central storage then there is always a possibility of a malicious attacker trying to access the information or Denial-of-Service (aka DoS) attack but with the use of RecordsKeeper Blockchain we can provide immutability and security for the same. Once the exam paper is over the RecordsKeeper Blockchain, it cannot be modified, deleted or tampered. Moreover the security is provided with the Cryptographic algorithms being used with RecordsKeeper where you can encrypt the exam paper and store it over the RecordsKeeper Public Blockchain. As the RecordsKeeper network is made up of multiple peer-to-peer nodes, there is no central storage available for conducting Denial-of-Service attack as all the the nodes are synchronized with each other.

  • Authorities leaked the exam paper

The major concern point of the CBSE exam paper leak was that the authorities who had access to the exam papers were the focal point for the leak of the exam paper. RecordsKeeper provides a solution to this in a very neat and effective technological way. In RecordsKeeper, everyone who has access to the Blockchain has their own private-public key pairs. Everyone – be it schools/students/authorities/agencies can create a private-public key pairs. The CBSE board can have multiple private-public key pairs for different exam papers. Now the private key is to be securely kept with the person but they can share their public key to the rest of the world. In our scenario, the following path can be taken to solve the problem.

  • CBSE board generates a key pair for each exam.
  • The people/agencies who need the access to the paper can share their public keys through secure internal channels with the CBSE or the CBSE board themselves can generate key pairs for all the schools who require the access to exam papers and share it with them. This process can be online & automated.
  • The exam paper (in JSON/XML Format) is encrypted using the exam private key by the CBSE board. (First Encryption)
  • After that, once the head of CBSE has all the public keys of different schools then they can encrypt the exam paper again (second encryption) by the school’s public key to make sure that only the school registered with the CBSE only has access to the exam paper through their respective private keys. Here the public-key of the respective school needs to be the part of the exam itself to trace back school easily in-case of any leak.
  • The encrypted exam paper is published over the RecordsKeeper blockchain along with . This will create multiple transactions entry over the RecordsKeeper for individual school. There may be 30,000-40,000 CBSE Schools all over the country.
  • The uploaded exam paper’s record identification key is shared with all the respective schools once it is uploaded over the RecordsKeeper Blockchain. This will ensure that they all have the encrypted exam paper ontime. Ideally can be done 24-48 hours before the exam. Now the magic of RecordsKeeper comes into play – the school have the access to the exam paper through their respective individual recorded transaction and they can decrypt the exam paper using their own private key. Please note they will still not able to access the exam as it is also encrypted by CBSE’s private key & they need the public key of the CBSE to decrypt it.
  • This way of uploading data over the RecordsKeeper Blockchain provides a way for the CBSE board to monitor the access of the exam papers and it also makes sure that the exam is not reached to an unwanted party.
  • CBSE announces the exam public key just before the exam. May be 30 minutes or so.
  • The authorities now can decrypt the exam using the exam public key. Convert it into printable format using simple tools like JSON/XML to PDF converter.
  • Finally the exam paper is distributed to the students.

Please note each paper will have the public-key or record-key of the school printed in small letters (in background, like water mark) of the question paper all over the question paper. Not at just one corner or page of the exam paper. This will easily allow the regulators or investigators to trace the school in case of any leak. Since only the principal will have the access of the private key pinpointing the human will be much easier.

Using RecordsKeeper Blockchain to distribute exam makes sure that every activity is being tracked and if somebody tries to maliciously access the paper then it will be recorded over the RecordsKeeper Blockchain and the culprit can apprehended as soon as he/she tries to access the exam paper.

We can take a step further in security by creating the key pairs for students and with that the students will have direct access to the exam without any 3rd party mediums and dependencies.
