Blockchain Security Issues and Legislative Challenges

Blockchain developers confront a wide array of security challenges. They must also adhere to emerging blockchain regulation established by government legislation. Let’s examine a few of the challenges that need to be addressed in 2019 and beyond. Security Challenges Protocol Backdoors/ Rogue Developers One uncommon yet highly concerning issue with blockchains is the possibility of massive, unplanned token issuances. The most prominent example of this occurred in October 2018 with Oyster Protocol (PRL). The project founder and chief developer, known as Bruno Block, decided to exit scam by emptying $300,000 of PRL from a platform smart contract backdoor and then selling it on KuCoin. This case study demonstrates a major security flaw of blockchains for three primary reasons. First, no one knew that Bruno Block had the ability to do this without warning. Second, this showed that it’s possible for one individual to take down the entire value of a cryptocurrency project. Finally, this created quite an uproar due to the fact that the project was previously one of the most promising in the cryptocurrency space. Compared to other cryptocurrency scams, Oyster Protocol showed none of the classic signs. Major Bugs Even highly decentralized blockchains face constant security threats. This is especially true for those that launch new code updates which could contain bugs. For example, Ethereum planned to launch its Constantinople update in January 2019. However, smart contract audit firm ChainSecurity found a major bug just around two days before the expected launch date. According to ChainSecurity, the issue was a flaw that could have led to a “reentrancy attack.” Essentially, this meant that someone could enter the same function multiple times without updating the user about the state of affairs. In this scenario, a hack could basically withdraw funds forever. Consequently, the Ethereum core development team decided to delay the launch until February 2019. While developers fixed the bug and averted a potential security crisis, it’s clear that flaws in the code written for blockchains can sometimes be difficult to find even with immense resources. Countdown to Constantinople from January 2019 51% Attacks In 2018, the rise of 51% attacks showed that it was possible to hack major blockchains and gain control over a majority of the hash power. Many blockchains that were once considered too expensive to take over via 51% attacks fell victim. During bear markets, the cost of orchestrating these attacks reduce significantly. By design, Proof-of-Work blockchains with fewer miners and less hash power are particularly vulnerable. Of course, several possible solutions exist. Some examples include requiring a higher number of confirmations or establishing merged mining. Additionally, using another type of consensus mechanism could present a possible solution. Nonetheless, the fact that many of the top blockchains today use Proof-of-Work continues to present a lingering problem. End Users The above issues demonstrate issues with centralized control and potential bugs. Still, these aren’t the only security issues to be concerned about. In many cases, security issues appear on the user side. For instance, the accessibility of cryptocurrency funds continues to be a major challenge. Despite warnings from crypto exchanges, project teams, and others, phishing attacks continue to cause many people to lose crypto funds.  Additionally, problems exist with how users must interact with cryptocurrency wallets. On the one hand, some people store funds offline in hardware wallets, save seed phrases in secure locations, and take measures to generally increase fund security. On the other hand, many users simply keep funds online, locked up in exchange wallets. Yes, it’s typically easier to access funds by choosing the latter option. Still, this comes with a much higher probability of losing funds to hackers. One of the biggest technical challenges for developers is to to find a better way of increasing accessibility of funds without sacrificing security. Although hardware wallets provide more security for end users, they aren’t as accessible as other wallet types. Legislative Challenges Blockchain regulation is another issue that developers must consider. There are several questions that have yet to be answered on this front. For instance, which laws apply to blockchain technology? If a blockchain is accessible anywhere around the globe (as most are), how do developers remain compliant with varying laws in numerous jurisdictions?  GDPR Legislation like the GDPR in the EU was originally intended to be neutral and protect the data of end users. Nonetheless, it can be difficult to determine how exactly how the law works with emerging technologies like blockchain. As an example, who is the controller of data in a public blockchain? Because consensus is decentralized and distributed across validators, no single entity is responsible. Compared to Web 2.0 big tech companies (Google, Facebook, Amazon, etc.), it can be much harder to pinpoint who controls and manages data with blockchain-based Web 3.0 software. In the era of blockchain data processing, what counts as personal data? Public keys, for example, do not have the same features as anonymous data and their characteristics are more similar to pseudonymized data. In the future, it’s possible that developers will design blockchains to not only address security challenges but also legislative ones. Ultimately, this calls into question whether or not it’s possible to develop systems that can achieve both. Just as with any newer technology, the formation of standardized blockchain regulation is likely to take some time. In the meantime, the technology itself continues to rapidly evolve in many facets. Centralization vs. Decentralization As governments begin to establish blockchain regulation standards, questions beyond data ownership and data privacy start to pop up. Most of today’s most well-known blockchains are publicly accessible and highly decentralized. However, it’s possible that blockchains of the future would become more centralized, especially those used by large corporations and/or governments. Centralization might present a few interesting, real-world security dilemmas. Blockchains that are controlled by a central authority or a majority of validators belong to one individual essentially open up the possibility of censorship. This goes against the grain of what most blockchains represent in 2019. If blockchains of the future are more centralized, this could make it even easier for bad actors (i.e. hackers) to gain control of sensitive data. While centralized blockchains would probably still be more secure than older database technologies, they would not be able to reach the level of inherent security provided by decentralized ones.  The post Blockchain Security Issues and Legislative Challenges appeared first on CoinCentral.

Ethereum [ETH] and Tron [TRX] Price Analysis: Ethereum’s bullish momentum wanes while bears control Tron

Ethereum, the second largest cryptocurrency in the world, has been consistently facing competition from Tron. Ethereum has been struggling to scale, which has contributed to a lot of users migrating to Tron, even after Ethereum’s Constantinople update. Tron has been doing well, with several developments in the ecosystem like, Tron and USDT partnership, the launch of Sun Network etc. Ethereum 1 day chart Source: TradingView Support 1: $80.72 Resistance 1: $181.63 Resistance 2: $248.64 Resistance 3: $318.18 Resistance 4: $478.76 Bollinger Bands showed a widening of the band, indicating the influx of volatility into the market. The price was moving closer to the simple moving average, which indicated that bullish momentum was waning. The Chaikin Money Flow indicator crossed the 0.2 line and was dropping, nearing the zero-line. This indicated a reduction in the money flow. The Stochastic RSI indicated a bearish crossover after reaching an oversold zone. Tron 1 day chart Source: TradingView Support 1: $0.0119 Resistance 1: $0.0267 Resistance 2: $0.0396 Bollinger Bands showed a similar scenario to that of Ethereum’s i.e., widening of the bands which indicated the influx of volatility in the Tron market. The price for TRX moved below the simple moving average, indicating bearish momentum. The Chaikin Money Flow indicator crossed the zero-line, implying a reduction in the money flow and transfer of power from the buyers and into the hands of the sellers. The Stochastic RSI for Tron showed an extended drop of the bearish crossover, about to hit the oversold zone. Conclusion The technicals for Ethereum looked like they might follow Tron’s lead. The indicators for Ethereum were lagging. Ethereum was partially bullish, when compared to Tron, as indicated by the Bollinger Bands, CMF, and Stochastic indicators.

Ethereum vs EOS: The Neverending Battle

The rivalry between Ethereum and EOS has been inevitable from the start. The idea behind EOS was to outstrip Ethereum, in one way or another. EOS aims to become a solid foundation layer for developing dapps and, at the same time, promises to solve the issues Ethereum has been struggling with. However, Ethereum is steadily holding its ground and has no intention of ceding. Although both blockchains are clearly contributing to a similar purpose, their fundamental premises are not the same. And as both competitors have their fair share of pros and cons, it is not that easy to establish which one is better. Major Differences Bitcoin paved the way for everyone. The Ethereum creators saw an alternative path in the smart contract. The new blockchain offered an ecosystem to make the work of developers easier and allowed them to build on top of it. EOS, in turn, is focused on perfecting that ecosystem and making it way more comfortable and secure. But what’s actually different? Decentralization is the cornerstone of Ethereum. Its community is driven by the sole idea of decentralization, but, as it often happens, the main advantage gives rise to some serious problems. Ethereum’s initial Proof of Work consensus algorithm is of a probabilistic type, meaning that we have no idea when and what node will confirm the next block. The network relies on miners and this causes major scalability issues. Think of this: it only took one cute little cat game to challenge the entire network. At the beginning of 2019, on February 29th, Ethereum activated its long-awaited Constantinople and St. Petersburg updates. This will eventually lead to fully adopting Proof-of-Stake algorithm, cheaper transactions and has already resulted in reduced mining awards. EOS took a different approach. Rather than focusing on decentralization, the blockchain made the scalability problem their number one priority. EOS designers implemented a Delegated Proof of Stake consensus deterministic algorithm. This way, we know exactly when and which node confirms the next transaction. The algorithm suggests that only 21 block producers will be in charge of confirming new blocks. The users ‘delegate’ their votes to BPs, that act as nodes. The nodes take their turns in a timely and strict order. And that’s how the network cuts the time of transaction confirmation significantly. The Mining Crisis EOS claims it doesn’t have miners, but has Block Producers instead. Technically, BPs are just remastered version of miners. Although they are not motivated directly by the amount of reward, they do the work to get their votes and be selected as one of the top 21 who get to solve the blocks. And, eventually, get their reward. Users vote for Block Producers and their voices value according to the amount of EOS token they hold. And EOS transactions are conditionally free. The network uses a bandwidth system, so it all comes down to how many tokens you hold. On the other hand, Ethereum runs on gas and each transaction requires a fee. The problem is that gas is limited and the transactions can be pricey, especially if you want to make a few of them (let’s say while playing a crypto game). For now, by activating Constantinople, Ethereum has managed to reduce block reward issuance from 3 to 2 ETH. As you might have guessed, miners were not thrilled by this update and some of them had to give up mining ETH, as it had turned into a bad bargain. Ethereum mining is going through some tough times. As it utterly and completely depends on the price of electricity and is still profitable in specific locations like Ukraine or China, but for US miners, the numbers haven’t been matching up very well. Some miners had no choice but to look elsewhere. Embracing Them Both However, some mining pools can take the liberty of being flexible. One case is MinerGate, a large mining pool that has decided to broaden their experiences and enter a poll to become an EOS block producer. The company is not abandoning Ethereum completely, but is willing to give the EOS network a shot. Claude Lecomte, the CEO of MinerGate, made it clear that the company has a clear vision of their role within the EOS community: “The more Block Producers with different ideologies, the more developmental options for the EOS network. We think it stands to reason that people who believe that EOS needs specialists in high-load services, DApps support, and organic community growth should vote for us. You simply aren’t going to find a better option.” On its way to change the realm of dapp development, MinerGate has partnered with Lumi, a crypto wallet known for its involvement in the Ethereum dapp community. A newly-hatched block producer has been in need of a “private, productive, well-designed, visually attractive and easy to use, besides being secure” EOS wallet. And that’s when they noticed Lumi Wallet, who fit that bill, and decided to embark on the EOS journey together. Diana Furman, the CEO of Lumi, explained why her team immediately bought the idea, added EOS support, and focused on the dapp market: “We want to engage with the EOS community and become an integral part of it. Lumi has always been into DApps, so we’re more than excited to play our part in the EOS DApp development. We are ready to listen and act. We want to become experts in terms of what the community needs and providing it with what is necessary.” This partnership illustrates that with a positive and open-minded approach, businesses don’t even have to choose between the platforms, and can work with both of them at the same time. Other Technical Features As we mentioned earlier, EOS was created to ease the life of developers and they are free to choose their preferred programming language as they please. In theory, Ethereum allows the same but in practice, everyone’s using Solidity. The model of Ethereum-based smart contracts is pretty obvious: there’s an address and there’s a transaction, users and smart contracts have equal rights to initiate transactions. With EOS it’s slightly more complicated. To initiate certain transactions you have to get permission first. This way, you can be really flexible when it comes to establishing levels of access, it also contributes to security, and modernizes the update system. Ethereum has a delegate call function that allows access to the resources from one smart contract to another. In EOS you can design a whole system of which contract, address, or account has access to the storage. To fix Ethereum bugs you need a fork. EOS allows block-producers to ban certain contracts and fix the bugs with no forks involved. EOS Critics For some, it might seem that EOS is leading the developers’ race. However, its centralized model is often criticized. Nick Szabo, a famous cryptographer known for his research in the area of smart contracts, called the EOS protocol into question: “In EOS, a few complete strangers can freeze what users thought was their money. Under the EOS protocol, you must trust a ‘constitutional’ organization comprised of people you will likely never get to know. The EOS ‘constitution’ is socially unscalable and a security hole.” Moreover, EOS’ unique ability to execute multiple transactions in parallel has yet to be proven in practice and, for now, the only option that we have is to trust what the whitepaper says. And, frankly, just saying it doesn’t mean much. Hopefully, with the $4 billion that EOS managed to raised via its year-long ICO campaign and the talented people working on the project a real-life solution will be delivered. Market and Community As for the market, Ethereum-based dapps are the ones that generate greater volume. The platform has been around for longer and people tend to trust it more.    Ethereum market capitalization, at the time of writing, is almost $15 million, while EOS’ looks rather modest with its $3.7 million. The 24-hour volume of ETH is $4.6 million vs EOS’ $1.7 million. And, finally, social media engagement which, in a way, indicates the level of community involvement – Ethereum’s Reddit counts 433k subscribers vs EOS’ 63.7k. The Bottom Line Ethereum has to get rid of the ICO-related vibe and once and for all figure out its scalability issue. EOS must yet prove itself, and its founders should start delivering what they have promised. Both blockchains have complicated problems to solve and the resources to do so. Both blockchains have skilled developers and enthusiastic communities behind them. Healthy competition is a massive motivation for Ethereum and EOS to speed up the process of working out their separate issues. The platforms can even co-exist and find their own niches on the wayward path of the blockchain’s evolution. The post Ethereum vs EOS: The Neverending Battle appeared first on ZyCrypto.

Ethereum Predictions for 2019: Will the Bulls or the Bears Win Out?

2019 could be a big year for Ethereum. The Constantinople hard fork eventually went through with barely a hitch. The first projects using Joseph Poon’s Plasma scaling technology will go live in a matter of months. There are still more developers and dapps on Ethereum than on any other blockchain platform. For these reasons, many Ethereum predictions for 2019 err on the bullish side. However, when Ethereum launched back in 2015, it had the advantage of being the first of its kind. This is no longer the case. Vitalik Buterin’s creation is now jostling for space between up-and-coming dapp platforms such as Tron, EOS, and Zilliqa. Pretty much every new launch claims to knock spots off Ethereum in terms of scalability and ease of use. We’ve been out trawling Twitter, Reddit, and the crypto news-scape to round up some of the current thinking on Ethereum predictions – bulls and bears alike. Ethereum Predictions: The Bulls Nick Cannon of makes a pretty credible bull case for the price of Ethereum, based on increasing scarcity. The Constantinople upgrade reduced the block reward for miners from three to two Ether. The next significant update is Serenity, currently set for implementation in 2020. At that time, Ethereum will move to the proof-of-stake (PoS) consensus model, and the block reward will be removed altogether. Cannon also points to the high value of ETH staked in decentralized finance projects such as Maker, creating further scarcity in the supply. His Ethereum predictions state that while the bull run may not happen this year, the increasingly scarce supply means it will happen eventually. ETH staked in DeFi, mostly Maker. Source: $2500 by Year’s End? Adam Todd of soon-to-launch futures exchange Digitex is even more bullish. His Ethereum predictions for 2019 include the price going up to around $2000-$2500. Of course, Digitex is developed on Ethereum so that would be great news for his company if it proves to be the case. Todd argues that the current low price of ETH is due to manipulation and points to EOS as being part of the problem. He claims that because the $4 billion EOS ICO was held on Ethereum, it drove the price down once the EOS main net went live. Now that it has a chance to recover, he believes it could skyrocket. Wall Street appears to be backing up Todd’s view. Tom Lee of Fundstrat Global Advisers reportedly told his clients late last year, “We believe Ethereum is about to stage a trend reversal and rally strongly.” Nigel Green of the deVere Group also threw his hat in the ring of Ethereum predictions. He too believes that the price will go up to $2500, driven by more platforms using Ethereum and the rise of cloud computing. He also predicted further regulation is on the way, leading to greater protection for investors, which would increase confidence in the markets. Ethereum Predictions: The Bear Case Crypto journalist Matthew Da Silva leads the bears. He’s an outspoken critic of Vitalik Buterin, stating that “it’s hard to see how his invention has made any difference, beyond inflating the crypto bubble.” His Ethereum prediction is that the ETH value is approaching its rightful price: zero. Harsh. For context, here is what I wrote: — Matthew de Silva (@matthewde_silva) September 12, 2018 Crypto website Wallet Investor is a little more generous, although less than reassuring for anyone all-in on ETH. Their analysis is that the price will more than halve from its current value of around $140 to about $63. It doesn’t explain why this is though, just stating that their predictions are based on “smart technical analysis.” Blockgeeks founder Ameer Rosic is similarly bearish, stating his belief on Twitter that we can expect another “80% haircut” for the crypto market overall. He’s also pretty scathing about Ethereum’s dapp user base. Presumably, this is the reason for his bearish outlook. If you think the bear market is bad now, just wait… Prediction: We will see another 80% haircut. Reality will soon set in. Ethereum. $20B MCap. Really? only 1200 Dapp users lol EOS: $4B Mcap. Based on what? zero adoption. Tron $1.8B Mcap. Where do I even begin!! — Ameer Rosic (@AmeerRosic) October 18, 2018 What Do the Ethereum Experts Think? Buterin himself has been famously uninterested in price hype, preferring instead to focus on the potential of blockchain technology. However, in a recent episode of the Unchained podcast, he conceded that the ETH price does matter. He elaborated that if it goes to zero, network security inevitably becomes compromised. He also admitted that Ethereum has lost some of its market share to newer entrants. However, as always, he didn’t make any specific price predictions. If Ethereum has lost out on market share, Joe Lubin appears to be less than concerned. Back in December, the founder of ConsenSys unleashed an epic tweetstorm of facts and statistics to back up his view that blockchain is “more than a market. It’s a movement.” Market cap doesn’t reflect activity. Decentralized networks are growing. -10B+ daily API requests served by @infura_io -1M+ @trufflesuite downloads -1M+ @metamask_io downloads -12K+ live @Ethereum nodes -48M+ unique #Ethereum addresses -3x @LinkedIn #blockchain job openings — Joseph Lubin (@ethereumJoseph) December 1, 2018 Our Two Cents For what it’s worth, here are our two cents. Ethereum’s biggest weakness has always been scalability. That mattered less when it was still the dominant platform; however, there are new kids in town now. If the Plasma protocol achieves what it aims to, and Ethereum can compete with rivals like EOS on transaction speed, then it could retain its position as the developer platform of choice. The Serenity upgrade and the decentralized finance movement also make the bull case a fairly credible one. Plus, crypto markets overall have been showing more positive movements of late. Although $2500 may be a tad ambitious, our overall prediction is that Ethereum still shows plenty of potential for a bright and bullish future.

BTC and ADA Are Showing Positive Signs With Strong Bullruns and Weaker Corrections

The cryptomarket is going through some good times, recovering from the sharp fall it had during 2018. The recovery of the global marketcap, and the high number of developments around cryptos and blockchain technologies has led many analysts to claim that we are close to witnessing not only a stabilization of the markets but also a bullish trend in the short term. Of all the crypto currencies on the ecosystem, BTC has always been the reference token, not only for holding the most powerful position in the top 10 but also for having the highest number of users and software developments. BTC is Having a Great Week BTC has experienced a significant price increase. After a period of constant “Bart Simpsons”, it finally seems that the most important cryptocurrency in the world broke the 5k resistance. This marks an a crucial milestone as it is a a value that could not be reached for months. However, during the last few hours BTC was curiously bullish. The token easily broke the 5.4K to flirt with the 5.6K band. If this trend continues, it could be said that BTC has been bullish for the entire past week, winning between 500 to 600 Dollars per token. BTC. 30 minute candles. After the big green candle, 5580 has become a new support Bitcoin (BTC) 1day candles. courtesy Tradingview Cardano (ADA) Also Shows Some Positive Signs Another token that has been specially bullish is Cardano (ADA) The project that promises to solve the “blockchain trilemma” experienced a a surge of about 10% in less than 24h, standing at one point almost at $0.08 per token. One of the reasons for this rise is the positive reaction of the market to the announcement by Charles Hoskinson (head of the project) saying that IOHK managed to close a an association with the Ethiopian government to popularize the use of Cardano in that region. According to Mr. Hoskinson, thanks to this partnership the Ethiopian authorities, the government will allow its citizens to use ADA to make payments as if it were fiat. Also, residents of Addis Ababa, the capital of the country, will be able to use ADA to pay for public transport services in the city. Right now, Cardano (ADA) experienced a correction that placed the token back to the support at 0.074 USD. The token then went up again to 0.075 with signs of another possible bullish trend in the short term Currently the bullish trend seems to be solid in most of the markets. The signs of a trend reversal are not strong enough to be frightened, however it is important to follow the charts, remembering that cryptocurrencies are extremely volatile.
