What is NEO ?
What is NEO? It has been dubbed the “Chinese Ethereum,” and this description goes a long way to illustrate what it does: provides a native Chinese platform for tokens and decentralized applications, similar to Ethereum but with important technical differences.
NEO exists to bring the blockchain to Chinese developers, businesses, financial institutions, and even the government. Its tokens and decentralized applications can do anything the Ethereum network is capable of doing, with decentralized applications able to be programmed in several programming languages.
Moreover, NEO is not a mined currency — there were 100 million issued at the beginning and that is all there will ever be — so there is never a wait for blocks. It’s important to note that 50 million of these NEO were held back by the NEO Foundation in order to administer development.
There are no transaction fees on the NEO network, although there could potentially be in the future. However, GAS tokens are used to power smart contracts, and the fees are paid to NEO holders. A lack of transaction fees is intended to keep the network growing, which benefits all NEO holders. The more assets registered on the NEO blockchain, the more gas that NEO holders are rewarded with.
The price per NEO began at less than $0.60 cents, but since then it has seen highs of as much as $150.00. Demand for NEO, like Ether, especially increases when token sales on the platform are active.
While many tokens are built on a “Proof of Work” or “Proof of Stake” foundation which enables their blockchains to agree on transactions and histories, the NEO token is a little different. It uses a niftily-titled consensus mechanism called “delegated Byzantine fault tolerance” which, it is believed, may enable NEO to scale more efficiently than other consensus proofs, and protect better against bad actors.
NEO was previously branded “Antshares,” but it has seen the vast majority of its interest and economic growth during the period since its rebranding.
An important concept to grasp when understanding NEO is the “Smart Economy”, which is a cornerstone of the token’s offer. Essentially, when we refer to the “NEO Smart Economy,” we are referring to an economic model where contracts are written in code and executed automatically as opposed to agreements made and enforced by humans.
This technology can be used in any transaction currently conducted by a bank or other legacy institution. By conducting business on the NEO blockchain, transactions can be given a degree of transparency as well as the security of a consensus-driven network.
Trust is removed from the equation in smart economics — there is no need to trust that the other party will act in good faith, as the contract will simply not function if any effort is made to not act in good faith.
As a result, business can be conducted more fairly, and problems generated by cultural and language barriers can be eliminated in code.
Perhaps just as importantly, the implementation of the Smart Economy – in NEO and elsewhere – introduces a new level of efficiency which can reduce costs, the savings of which will inevitably be passed onto end users of financial products.
In the NEO Smart Economy, all real assets can be digitized through decentralized applications. Institutions as varied as stock exchanges and rental agencies can find utility in a blockchain if it is inexpensive enough to use. Having low or no transaction fees as well as a fast network makes NEO an attractive platform.
What is GAS In The NEO Equation?
Along with the base token of NEO, GAS was launched with an identical maximum supply. GAS incentivizes people to hold NEO in that it slowly accrues in the account of every NEO holder over time, based on how many NEO they hold. There are calculators that give you an idea of how much GAS you can expect to earn. GAS will reach its 100 million mark in roughly 2039.
Aside from a financial incentive to hold NEO, GAS works in the same way that Ether does on the Ethereum network — it’s a requirement for launching smart contracts or other forms of decentralized applications on the network. While NEO can only be divided into integers like 1, 2, 5 and so on (unlike the dollar, Bitcoin, or most cryptocurrencies, which can have many decimals), GAS and other tokens can be subdivided the same way that other tokens can be.
Because of the utility of GAS, some believe it may eventually be worth more than the NEO token itself. Historically its price has charted at about 1/3rd of that of NEO, but one can expect this to change, especially when GAS dividends run out and the only way to acquire it is through exchanges.
Other NEO Tokens
Red-Pulse was the first Initial Coin Offering conducted on the NEO blockchain. Red-Pulse is a company which does market research in China for westerners. They were already providing subscription-based services prior to their ICO. The purpose of the Red-Pulse (RPX) token is to incentivize research and honest reporting about China.
Since then, major projects such as Ontology, DeepBrain Chain, Qlink and Trinity have all used the platform for significant raises.
As more and more tokens are registered on the NEO blockchain, it’s reasonable to expect a thriving token economy on the NEO blockchain just as is seen today in Ethereum, each with its own unique purpose and anchoring economy.
- NEO is the first blockchain platform within the Chinese economy with similar functionality to Ethereum, but without mining or proof-of-stake.
- NEO has a market capitalization of over $4 billion (March 19th 2018), with daily volumes exceeding $100 million.
- Half of all NEO ever generated were kept with the NEO foundation and are sold occasionally to fund development and infrastructure.
- The Foundation actively develops NEO: ongoing improvements are an important feature for modern cryptocurrencies.
- NEO lacks transaction fees but the GAS token is a requirement for executing smart contracts on the NEO blockchain.
- Several tokens have been issued on the NEO blockchain.
- While there are billions of dollars wrapped up in the NEO blockchain, NEO’s purpose is not to disrupt the Chinese RMB or any fiat currency, but instead help bring the Chinese economy into the blockchain era.
What is Qtum (QTUM) ?
The emergence of cryptocurrencies has been accompanied by a wave of innovation that has put the nascent sector into the spotlight. Bitcoin’s model has been replicated and improved upon, and other cryptocurrencies have offered up their own takes on blockchain.
Alongside the industry’s expanding popularity, more companies are looking for ways to capitalize on blockchain, and existing solutions for development have shown their limitations. Ethereum, for example, is the most popular solution for blockchain-based apps, but recent events have prominently displayed its problems with scale and managing large network loads.
With these issues in mind, the Singapore-based Qtum Foundation created their own blockchain solution – QTUM – which deploys the more stable bitcoin chain while providing an app development environment akin to the capabilities Ethereum currently provides. The company is aiming to offer businesses an improved smart contract platform that extends functionality along with a more secure and transparent environment.
What Is Qtum?
At its core, Qtum is a cryptocurrency designed to simplify the use of smart contracts for inter-business and institutional operations. More than simply a coin, however, the foundation created a blockchain solution that combines several aspects of two major cryptocurrencies – bitcoin and Ethereum – to facilitate interoperability between the two and take advantage of their major benefits.
Qtum is built on a bitcoin core fork, but the foundation has created its own hybrid blockchain with the help of several key tools. The coin uses bitcoin’s chain because of its simple and stable nature, allowing the foundation to build upon it more easily.
On top of the foundation, it uses a layer of abstraction that enables Qtum to combine several virtual machines that contribute different functionalities. Most important among these is the Ethereum Virtual Machine, which gives Qtum the ability to create its own smart contracts.
On a more granular level, however, each layer has a specific purpose. The bitcoin chain offers the foundation the ability to use the UTXO (Unspent Transaction Outputs) model, a simplified version of accounts that eschews the traditional banking account model in favor of a more peer-to-peer oriented one.
Instead of individual accounts that have sums debited when a transaction occurs, all transactions are written as bank checks. This way, users must specify just who the amount is being credited to, and the reason, simplifying the smart contract creation process. Users’ “balances” are then just the total of all the transactions they can complete.
The problem with UTXO is that Ethereum uses a more traditional account model, where users have balances that can be debited to complete a transaction, and their destination accounts have the same sum credited. This is one of the bigger problems in bitcoin-Ethereum interoperability, one which Qtum solves with an Account Abstraction Layer that translates bitcoin’s UTXO outputs into account-style data Ethereum can interpret.
The Ethereum aspect is the other major component of Qtum, as it allows for the creation of smart contracts and decentralized applications (dApps). However, by combining it with bitcoin, Qtum draws on Ethereum’s attributes to focus its sights towards business and institutional adoption. All told, Qtum’s blockchain is based around stability, interoperability, and modular design, helping contribute to its overall value.
Proof of Stake – Qtum’s Value-Added Proposition for Businesses
One other major difference between Qtum and its building blocks that serve as the foundation for the platform is its use of Proof of Stake consensus over the more traditional Proof of Work.
PoW is the standard for bitcoin and is based around miners who validate transactions to create new blocks. The system was useful initially as adoption rates were low and processing each block was relatively easy.
The problem with PoW consensus is that as chains expand and the number of transactions increase, solving each block becomes significantly harder. This manifests in several ways. The first is that mining takes significantly longer, slowing down the overall speed of the network and transactions. The second is that because mining becomes exponentially more complex, better computers and systems are required, as well as large amounts of real-world power.
Mining operations use substantial amounts of electricity that costs fiat currency, putting pressure on cryptocurrency values. For business purposes, PoW becomes inefficient as thousands of transactions must be processed quickly and at relatively low costs. Having to wait hours for a transaction to be recorded and completed means businesses lose fiat money while they wait.
PoS consensus, on the other hand, randomizes the creator of every new block on the chain by introducing a deterministic algorithm that chooses based on wealth, or a user’s stake. This removes the block rewards for miners, and also the need for increasingly costly mining operations to which bitcoin and others have fallen prey. More importantly, all coins are mined when the blockchain is created, so there is no real reward outside of transaction fees, lowering overheads and expediting the speed of transactions.
For businesses, this model is preferable as it removes the need for competition and ensures that transaction fees remain low enough to make the system viable. Furthermore, because there is no need for mining, there is also no downward pressure on cryptocurrencies’ values from miners having to sell cryptocurrency to cover fiat expenses.
What Are the Uses for Qtum?
The Qtum Foundation has angled itself as a solution for businesses, offering a better way to embrace blockchain without the inherent risks and complications associated with bitcoin and Ethereum, but with all the benefits. Qtum offers businesses several advantages over its predecessors, making it impressively useful in a variety of situations.
The most obvious is their hybrid smart contracts, which thanks to UTXO, are more secure than Ethereum’s version. While the latter created smart contracts, there have been several well publicized incidents where the technology has underperformed, causing millions in losses. Instead, bitcoin’s secure transactions are now usable with Qtum smart contracts, offering an extra layer of protection.
One of the biggest appeals for Qtum users is the blockchain’s ability to create lightweight dApps in almost any computer language, as opposed to Ethereum’s somewhat restricted library. There are already several applications built on Qtum’s chain, including traditional services like healthcare records and marketing, as well as more unorthodox dApps focusing on food traceability, prediction markets, and artist copyright protections.
More importantly, Qtum is hoping to attract bigger institutional actors and become a bridge for business-to-business transactions thanks to their smart contract design. The company’s use of UTXO and Ethereum smart contracts means that it offers a truly trustless ecosystem for transactions, fully removing the need for middlemen all while reducing overheads for businesses.
Qtum is past its initial stages and has already locked down agreements with several important companies that could quickly raise its profile while adding to its appeals as a central hub for blockchain development in the future.
The Qtum Foundation has already struck up a partnership agreement with Starbucks, though the terms haven’t been fully specified. Furthermore, to stay at the vanguard, the foundation has ironed out a relationship with China’s 360 Finance to create a blockchain research lab dedicated to improving the system’s underlying technology.
While still early in the year, many experts have high hopes for Qtum, and the cryptocurrency seems poised to fulfill its potential. While it must still prove itself to the private sector to gain momentum, the virtual currency could quickly become the dominant go-to for dApp development and offer businesses a safer, more effective, way to transact.

What is Bitcoin Gold (BTG) ?
Cryptocurrency forks of various types now take place on a regular basis. Even bitcoin has experienced several different iterations and branches in this way. One of the largest and most discussed bitcoin forks took place late in 2017.
Bitcoin gold was a hard fork of the original open source cryptocurrency which took place on October 24, 2017. While hard forks take place for a number of reasons – including for the purposes of scaling as a cryptocurrency customer base grows, or because of developer conflict and differences of goals – bitcoin gold’s stated purpose has been to “make bitcoin decentralized again.”
On the surface, the idea of “making bitcoin decentralized again” may seem counterintuitive. Bitcoin, like all other cryptocurrencies, is designed to be decentralized already; it is not linked with any central bank, particularly country, or government body.
One of the major issues with bitcoin which prompted the development of bitcoin gold, however, was not related to the question of central issuance at all. Rather, it had to do with the mining process. Bitcoin gold developers believed that by adopting a new algorithm for the mining process (in this case, a so-called proof-of-work algorithm called Equihash), the new branch of the world’s most popular cryptocurrency by market cap would not disproportionally favor major mining operations.
Democratizing the Mining Process
Bitcoin mining is a lucrative but resource-intensive process. The most profitable mining ventures are often those which pool together a large number of mining rigs, each of which requires expensive, special equipment.
Individuals attempting to mine for bitcoin on their own either have to invest a huge amount of money and time into creating their own rigs, or they get passed by in the process, as their computers are unable to compete with the professional rig systems.
One of the primary goals of bitcoin gold has been to change the algorithm by which the cryptocurrency itself is mined, meaning that the mining process cannot be run faster on specialized equipment than it can on standard computer systems.
Bitcoin gold was not the first major hard fork of bitcoin. Bitcoin cash forked off from the primary cryptocurrency in August of 2017.
In 2018, bitcoin is anticipating several additional hard forks, prompting some to speculate that there may be diminishing returns in terms of investor interest as more offshoots of bitcoin reach the market.
Distribution, Protection, Transparency
Besides the goal of “re-decentralizing” bitcoin, bitcoin gold’s developers were also focused on issues relating to distribution, protection, and transparency. “Hard forking bitcoin’s blockchain fairly and efficiently distributes a new digital asset immediately to people all over the world who have interest in cryptocoins,” the bitcoin gold website states.
In the world of virtual currencies, threats from hackers and other malicious entities are constantly a concern. For that reason, bitcoin gold took additional safety and protective measures from the time of its launch, in an effort to help secure its customers’ accounts and coins. These include replay protection and unique wallet addresses.
The fact that bitcoin gold is “a free open-source software project that is built by volunteer developers and supported by a rapidly growing community of bitcoin enthusiasts that stretches around the globe” is also a draw for potential customers.
Bitcoin Gold On Exchanges
For all cryptocurrencies, one of the major factors which helps to determine both short-term and long-term success is its availability on cryptocurrency exchanges. Users must be able to access the cryptocurrency on exchanges in order to make transactions.
According to the bitcoin gold website, as of March 2018, the cryptocurrency was trading live on Bithumb, Bitfinex, Binance, Bittrex, HitBTC, Uphold, YoBit, Gate.io, Changelly, Shapeshift, BitBay, Abucoins, Change Now, Evercoin, Tdax, Bitsane, Bitstarex, QuadrigaCX, Cex.io, Okex, Anybits, BestRate, Bitmarket, Indacoin, CoinSwitch, and Unocoin.
There are additional exchanges slated to offer bitcoin gold in the near future as well. The cryptocurrency is also available through a number of wallet services, including Trezor Wallet, Ledger Wallet, Exodus, Coinomi, Bitpie, Guarda, Freewallet, BTGWallet, and Kasse. According to the website, the cryptocurrency has been listed on 46 markets and 26 exchanges as of January, 2018.
Launch and Controversy
The developers of bitcoin gold used what is called “post-mine” after the launch. This was the retroactive mining of 100,000 coins after the fork already took place. The way that this happened was through the rapid mining of about 8,000 blocks, the results of which were set aside as an “endowment” of sorts, to be used to grow and maintain the broader bitcoin gold network.
About 5% of those 100,000 coins were set aside for each of the six primary team members as a bonus. At the time of the launch, all bitcoin owners received bitcoin gold coins at the rate of one bitcoin gold token per one bitcoin token.
Coinbase, one of the largest cryptocurrency exchanges in the world, was notably skeptical of bitcoin gold at launch time. Coinbase representatives stated that the exchange “cannot support bitcoin gold because its developers have not made the code available to the public for review. This is a major security risk.”
As of March 4, 2018, bitcoin gold has 253 reachable nodes. The highest concentration of nodes is in Germany (46 nodes), with the next-highest levels being the United States (38), France (37), and Russia (18).
In February 2018, bitcoin gold launched the bitcoin gold insight explorer, calling it a “fully functional bitcoin gold insight instance and web application service presenting the Insight UI and Insight API.”
Like most cryptocurrencies, bitcoin gold has had its share of detractors and controversies. Just days after the launch, miners accused one of the developers of bitcoin gold of having added in a 0.5% mining fee that was hidden from the mining community.
The Future of Bitcoin Gold
According to the bitcoin gold website, the cryptocurrency maintains ambitious plans for expansion into the future. In the first quarter of 2018, for instance, the website says its goals including “open source libraries integration” with BitcoinJS, BitcoinJ, and CoPay, as well as “academic and university collaboration” and “design and rebranding,” including a refreshed website.
In the second quarter of 2018, the digital currency aims to integrate a lightning network and decentralized mining through P2Pool. There is also a plan to integrate a debit card program and other payment systems integrations.
By the end of 2018, the cryptocurrency aims to develop “sidechains and cross-chain atomic swaps” as well as a number of meet-ups and developer conferences, university outreach, and more. Looking ahead to 2019, the cryptocurrency has its sights on private transactions and scholarship or research support.
Over the longer term, bitcoin gold will conduct research on smart contracts and blockchain democracy, as well as develop a decentralized fiat-crypto brokerage network.
Bitcoin gold developers are conscious of the connections between this cryptocurrency, its parent bitcoin, and the broader digital currency world. As such, they indicate that “the core improvements we’re working on are all of great interest in the broader bitcoin and crypto worlds, not merely for bitcoin gold.” They said some of these unilaterally applicable improvements may include scalable ways to address hard forks, “smart voting mechanisms,” and decentralized decision-making for the development of the digital currency.

What is NANO ?
NANO officially rebranded from RaiBlocks at the end of January 2018. The team behind the cryptocurrency, RaiBlocks announced that the coin is rebranded to NANO.
NANO follows Bitcoins‘ original plan which is to replace traditional currencies, making it digital money for day to day use.
In the quest of taking over Bitcoin, NANO addresses vital problems posed by Bitcoin network which are:
- Scalability problems which give users concerns about the increase in transaction fees on the Bitcoin network.
- Computational issues which have to do with the latency of transaction times which stands at an average of 164 minutes.
- Energy consumption is soaring high with Bitcoin mining consuming more electricity than 159 countries.
Addressing these challenges, NANO provides a solution which gives the cryptocurrency and edge over Bitcoin with its block-lattice structure which delivers zero-fee transactions and consumes way less energy than that of Bitcoin.
How The System Works
Unlike other blockchain technologies many cryptocurrencies adapt, each account has its blockchain. Each account-chain, as its also referred to is updated by the account owner and in turn, asynchronously updates the rest of the block-lattice resulting in fast transaction times. Since each user updates its block sending and receiving funds requires two transactions; a sending transaction which deducts the amount sent by a sender from his balance, likewise the receive transaction which adds amount gotten from sender to its account balance. These two transactions don’t have to be at the same time; the receiver can accept the transaction anytime.
Explaining Block-Lattice Architecture
NANO uses a Directed Acyclic Graph (DAG) block-lattice architecture, where every individual is assigned his blockchain. Unlike other blockchain architecture which tracks transaction amounts, the block-lattice records account balances. This method shrinks down data stored through the use of database pruning. Every blockchain reflects information related to individual’s account and is only updated by the owner; then each blockchain is updated asynchronously to the rest of the block-lattice.
As every user controls their blockchain, protocols such as proof-of-work (PoW) or proof-of-stake (PoS) in deciding on the state of the ledger is not needed.
To Create An Account
Users need to initiate an open transaction. This transaction is the first of every account-chain and is created upon receiving the first transaction block.
All balances are recorded within users account-chain. Instead of recording the amount of transaction, verification process requires checking the difference between the previous send block balance and the current one. The new block increases or decreases with the final balance on the new receive block. This is to improve processing speed when downloading high numbers of transaction blocks.
Sending From An Account
The sending address must already have an opened block, and therefore a balance. Once a transaction is initiated, it cannot be reversed once confirmed. Once the transaction is broadcasted to the network, funds are immediately deducted from senders balance and are pending until the receiving party signs the block to accept the funds. Pending acceptance, the funds should be considered spent on senders account though it hasn’t been received as the sender cannot revoke the transaction.
To complete the transaction process, the receiver creates a block on its account to accept a sent fund. Once the block is created and broadcasted, the account balance is updated with the new balance.
What’s Interesting About The Block-Lattice Infrastructure
Because of its lightweight protocol and cost of running a node next to nothing, transactions are processed without fees. Each transaction on the network is fitted in a UDP packet and handled independently, eliminating block size issues.
Also, wallets are pre-cached for the next transaction once a transaction is sent, making transactions instant as both sender and receiver have proof of work ready to go.
NANO’s Price Over Time
The NANO (represented as XRB symbol on most exchanges) has been stable, almost static at its lows since inception. Not until recently, the latter part of 2017, did we see a spike in price as it made a high of $4.02 on the 12th of December, 2017. It has since continued to make huge gains with all-time highs at $33.14. Currently at $13.27 after a pullback.
It is clear that after the rebrand announcement, the NANO has come into limelight and has had a good number of people adopting the cryptocurrency. The NANO currently has a market cap of $1.76 Billion.
Where To Buy NANO
NANO has since been added to significant exchanges after its rebrand. The NANO can be exchanged for major cryptocurrencies like the Bitcoin, Ether, Binance Token, Tether USDT, Doge, and fiat currencies.
NANO can be exchanged on Binance, Kucoin, RightBTC, Bit-Z, Mercatox, OKEx, and CoinFalconexchanges. You can also purchase NANO using cash on the BitFlip exchange.
NANO Compatible Wallets
There are a few options for storing and transacting with the NANO cryptocurrency. You can hold your NANO in the following wallets:
- There is an official web wallet, hosted on raiwallet.com.
- RaiWalletBot is a telegram bot which manages user private keys allows users access, send and receive NANO coins on the telegram app.
- You can also use the Ledger Hardware wallet to hold your NANO cryptocurrencies.
Plans For The Future
The NANO is aimed at revolutionizing the blockchain architecture itself and will undoubtedly have a bright future.
The community has helped get the cryptocurrency on quite a few exchanges, and we should expect even much more shortly.
Mobile wallets are currently under testing and would be released for iPhone and Android mobile devices early 2018.
What NANO aims to achieve is simple. To replace the conventional shared memory data structure with the message passing model in which users have their blockchains that only syncs with the main network. The NANO is the only cryptocurrency which employs the block-lattice (multi-dimensional blockchain) freeing users from paying fees to miners, waiting for network ledger update and also avoiding long transaction confirmation times.
With the solution NANO presents, cryptocurrencies, most especially the NANO will be that digital currency that replaces fiat currencies for everyday use.
