Blockchain

As with most blockchain startups, the story begins with a real-world problem. This problem centres on the global real estate industry, whereby access to reliable, secure and readily available data can be a somewhat daunting task. In terms of availability, data is often monopolized by a handful of industry leaders, making it difficult for external stakeholders to get a look in.

Moreover, with no incentives in place to share such data, organizations are motivated to control the information they possess. Real estate data that is available within the public domain is often dispersed across multiple independent channels, with no mechanisms in place to verify the accuracy of the provided material.

So where does this leave us in a data industry that is worth close to $25 billion? According to the team at Rebloc – the solution lies in robust data integrity and coverage, alongside privacy validation and incentivization – all of which can be achieved by democratizing real estate data on to the blockchain.

Who are Rebloc?

At an organizational level, the Rebloc project is a dual venture between two industry leaders from the real estate data and technology sectors. By combining forces, the project has installed talent with a proven track record. Responsible for driving the Rebloc project forward, Gary Yeoman has enjoyed a plethora of success in multiple real estate ventures. This includes Altus Group, where he served as CEO. The project also benefits from a strong board of advisors – including Elie Galam, Chief Investment Officer at Eastmore Group.

The venture is further bolstered by iLOOKABOUT veteran Jeff Young. ILA specializes in visual and data analytics, with a direct focus on supplying technological solutions for the real estate and property assessment markets.

Tokenization

Although the project is looking build their network on top of the blockchain protocol and as such, tokenize their in-house economy, the team have opted against going down the initial coin offering (ICO) route. This is the process of raising capital in the form of major cryptocurrencies and subsequently providing investors with a proprietary utility token.

On the contrary, the model centres on contribution. In other words, if you become part of the Rebloc democracy by collaborating in the sharing of accurate and readily available data, then you have the chance to monetize in the form of the Rebloc token.

The network will be built on top of the Enigma protocol, meaning that stakeholders can purchase, sell or exchange data through the utilization of smart contract technology. Moreover, this can be achieved in a safe and secure eco-system, whilst fully protecting the privacy of those involved.

How will Rebloc achieve its goals?

As per the information outlined in the Rebloc whitepaper, there are a number of angels that the team are looking to cover. First and foremost -to enable the ReBlock network to operate in an autonomous manner, when the end-user attempts to buy real estate data, the smart contract will extract this information from the relevant provider.

However, prior to the data transitioning over to the consumer, it must first go through a validation process whereby the smart contract will aim to reach consensus on the accuracy of the information. If this can be achieved, the consumer receives the data and the provider is subsequently remunerated for their contribution.

On the other hand, if the blockchain cannot reach consensus on the reliability of the data, the consumer is not charged. If this is the case, the data provider in question receives a proportionate penalty.

The reason for this is that it not only motivates stakeholders to ensure that the data they contribute is accurate – but it also ensures that the ReBlock network preserves its integrity.

A second angel that the ReBlock team are looking to revolutionize is the availability of data in real-time. The project aims to achieve this by utilizing an indexing strategy that is fully supported by the underlying technology of the blockchain protocol.

Essentially, indexing maintains a stringent database of information that can be shared without needing the validator to independently involve themselves in the transaction. By removing the centralized role of the provider, data can be extracted in a seamless manner without comprising on security.

Ultimately, for the project to achieve success in both the short and long-term, it requires a collaborative approach between all parties involved. What this means is that for the real estate data sector to flourish in a collective manner, the contribution of accurate, seamless and relevant data must be rewarded in a fair and transparent eco-system – which is something that ReBlock claim to be able to facilitate in the form of utility tokenization.

Let’s suppose that you are a newbie investor willing to try a hand in cryptocurrency. You have learned a lot about Bitcoin and altcoins, explored the reasons affecting their prices, and weighed all the pros and cons of investing in crypto. But where should you start? How to find a reliable platform to buy your first Bitcoin from?

What you need to understand is that the majority of exchanges support Bitcoin as it is the most popular cryptocurrency at the moment – and its market capitalization says it all. There is a vast choice of crypto platforms now, and therefore it is essential to pick the best Bitcoin exchange for your particular needs.

Bitcoin… But There Are Lots of Other Cryptos

First of all, Bitcoin is a crypto that is the most widespread. That means that you still cannot buy stuff for XRP or ZEC, but there are many retailers (both online and offline) that accept Bitcoin. In other words, Bitcoin is likely to be the first crypto to be accepted everywhere, and it is also currently the most established and recognized one.

Sure, it has certain downsides – transactions are sometimes too slow and the fees may be a bit high. However, if you want to play it safe, go for Bitcoin.

What to Look for in a Crypto Exchange?

Exchanges differ in many ways. The first thing is the number of currencies and types of trades they offer. For example, some exchanges may allow you to trade crypto for crypto, but there will be no fiat accepted. Others will allow using fiat but may not allow for various types of trading (margin trading, for example.) Finally, there are platforms that charge huge fees but have excellent service and vice versa.

For the newcomers, there are two most important factors to look for– safety and user-friendliness.

How to Find the Exchange I Can Trust?

One of the exchanges that will encourage every new Bitcoin buyer is definitely CEX.IO. It has a great user-friendly interface and trading there is made simple. Furthermore, you can rest assured that there will be no hurdles when you buy Bitcoin at the platform. Once you go through registration and verification, trading and buying will be a child’s play.

Is It Difficult to Register on CEX.IO?

Registering on CEX.IO is not a complicated process. You only need to take the following steps in order to create an account and start buying Bitcoin:

1. Click the ‘Register’ button;
2. Fill out the form with all the required details;
3. Turn on two-factor authentication for further security;
4. Verify your account via your email.

There are additional requests that you may get depending on your country of residence. For example, the CEX.IO team may ask you to provide an official document along with your selfie with it. This photo is then processed by the face recognition technology where the software determines whether your document is indeed yours.

How Can I Pay for Bitcoin?

Once the registration process has been completed and CEX.IO has verified your user account, you need to choose the most appropriate method that you will use for purchasing your Bitcoin. Now, there are three ways to pay for your crypto:

1. Wire Transfer;
2. Payment Card (Debit/Credit);
3. Other cryptos.

Of course, if you’ve ever made a payment online, you know that cards are a much faster and reliable option than bank transfers that sometimes may take days to be processed.

What Does It Take to Purchase Bitcoin Here?

First of all, go to the Buy/Sell tab to navigate to the instant-buy page. There you will find the offers for different cryptos against various fiat currencies – pick the one that suits you most and click ‘Buy’ under it.

There is also an option to buy a customized amount of Bitcoins. Just fill in the amount you are willing to buy and you will get an instant offer which is automatically calculated according to the latest price of BTC within the platform.

How Much Do They Charge?

Naturally, CEX.IO charges fees for transactions, which is something most of the websites do. Luckily for you, it is one of the most affordable online exchanges. The instant-buy option that we discussed earlier will cost you no less than a 7% fee charged from the amount of fiat currency. Keep in mind that every exchange of this type will also have deposit and withdrawal fees for fiat. So, if you are not familiar with how fees work, you can check out the fee schedule on their website for more information.

There is also a so-called Maker-and-Taker fee. In essence, these fees are imposed on the trading activity and are usually lower than those for the instant-buy option. Trading involves someone (the Maker) creating an offer, and someone (the Taker) accepting that offer. The fees for this type of activity are calculated on the basis of your 30-day trade volume; they vary from 0.1% to 0.25% for takers, and from 0% to 0.16% for makers.

Conclusion

Now that you have an idea on how to make an account and buy your first Bitcoins, you can proceed and actually do that on CEX.IO. However, make sure not to buy a huge amount right away – try to buy small first until you get the hang of things.

It is important to know that the journey doesn’t end here. In fact, this is just a start, and it is the perfect time to get informed about the crypto economy and other coins that exist.

The concept of smart contracts was first introduced by Nick Szabo all the way back in 1994. Since the development of Ethereum, the term has become more commonplace. Amid discussions of lawyers ultimately being redundant, the term “smart contract” has also become much misunderstood.

Even though there have been striding developments in blockchain since Szabo wrote his paper, his vending machine analogy to explain smart contracts is still fitting. The money goes in, and triggers the automatic release of a product, with the correct amount of change. This analogy also provides a starting point for explaining how the term “smart contract” has become misunderstood.

The Missing Link in Smart Contracts

In the example of a vending machine, the rules exist before anyone inserts money. There is no need to agree with the machine that you will get a soda in return for your coin—it just executes that agreement. The smart contract scenario is similar to a vending machine in that the terms must already be agreed upon for it to run.

In a real-life contract, the terms are drawn up between two parties, usually by a lawyer, before they are executed according to the agreement. So, the critical point here is that the smart contract itself is not the agreement of terms, it is the execution of the agreement of terms. The execution still requires the underlying terms to be agreed upon beforehand.

A large number of blockchain projects are already using smart contracts. However, many are still in the developmental stage and have not yet been deployed with mass adoption. Additionally, their use is generally confined to “if-this-then-that” scenarios.

For mainstream businesses, the agreement of terms remains the missing link in smart contracts. This goes some way to explaining why smart contracts are not yet being embraced by the mainstream, and also why lawyers have not yet been laid off in droves.

Barriers to Practical Application

This is not a mere technicality. The law dictates that businesses must have a written legal agreement for most transactions. Therefore, implementing smart contracts requires a further step—translation of the agreed written terms into code.

Given that business contracts are subject to audits, smart contracts are not currently fit for purpose as they cannot be read by human auditors. For this reason, some tech companies such as Quantstamp are building protocols specifically for conducting smart contract auditing services.

Furthermore, real-life agreements often change after the first set of terms have been agreed due to unforeseen circumstances or other reasons. In this case, written legal contracts can be easily amended, providing both parties agree. Smart contracts are not currently set up to be so flexible.

SciDex is a blockchain company that recognizes these challenges around smart contract adoption and is developing a protocol to effectively resolve these issues. At the core of the SciDex protocol is a concept that has been around a long time, but has not yet been fully exploited within distributed ledgers. The concept is known as the Ricardian Contract.

The Future is Ricardian

A Ricardian Contract is a contract that has two forms: one that is in plain text and another that is a digital contract. The former can be read like a standard document while the latter can be written in a programming language. They both reflect the same terms, just in formats that can be read by either humans or machines.

The Ricardian Contract was first proposed by Ian Grigg, a financial cryptographer who came up with the idea in the 1990’s. Around the same time that Ethereum was about to launch in 2015, Grigg developed his idea further, outlining the concept of the Ricardian Smart Contract.

This construct assembles the Ricardian contract which forms the legal agreement and its digital counterpart, together with the smart contract that can automatically transact the terms in the agreement.

The Ricardian Smart Contract goes some way to a solution for implementing smart contracts in companies. BOScoin is a cryptocurrency platform developing a similar solution using human- and machine-readable contracts.

However, there is still a further issue to overcome to enable business adoption—the requirement for adaptability. This is the final problem that SciDex aims to resolve, by way of its RASC protocol.

Enter Ricardian Adaptive Smart Contracts

SciDex has developed an Ethereum-powered protocol that introduces the element of adaptability to the Ricardian Smart Contract. Therefore, this protocol is known as the Ricardian Adaptive Smart Contract or the RASC protocol.

It is designed to meet all of the requirements for smart contracts to be implemented in real-life businesses. There is a legal agreement—readable by humans—also encoded into digital form and a smart contract that will execute the terms, in such a way as to be flexible in case something changes at the agreement of the parties. Contracts are digitally signed, and the outcomes are recorded on the blockchain.

Part of the flexibility of using the RASC protocol comes from the input of oracles. Oracles are nodes that validate external sources of truth, which determine specific elements of the outcome of the agreement. For example, a particular stock price fluctuation may influence the amount paid—this data would be taken from a trusted source by an oracle.

Mainstream Adoption of Smart Contracts in the Future

The adoption of new technologies is often a chicken-and-egg scenario, especially in business. Companies can be reluctant to test technology as a first-mover. But without such early adopters, the technology will never get off the ground.

Therefore, innovations like the RASC protocol represent an important development in encouraging first-movers and eventually, mainstream adoption.

Additionally, their use is generally confined to “if-this-then-that” scenarios.

For mainstream businesses, the agreement of terms remains the missing link in smart contracts. This goes some way to explaining why smart contracts are not yet being embraced by the mainstream, and also why lawyers have not yet been laid off in droves.
