Opera Releases ‘Web 3-Ready’ Android Browser With Ethereum, DApp Support

Opera has launched its “Web 3-ready” browser for Android, with crypto wallet integration, support for Ethereum and interactions with decentralized applications.

Opera has launched its “Web 3-ready” browser for Android, with crypto wallet integration, support for Ethereum (ETH) and interactions with decentralized applications (DApps). The launch was announced at the Hard Fork Decentralized event in London Dec. 13, according to a press release shared with Cointelegraph.

Charles Hamel, product manager of Opera Crypto, has outlined that the new product aims to remove the “friction” involved in “using cryptocurrencies online and accessing Web 3 via special apps or extensions,” in a bid to make the emerging technologies more “mainstream.”  

Hamel explained Opera’s choice to support Ethereum and the Ethereum Web3 API as being based on the perception that the protocol “has the largest community of developers building Dapps” and significant “momentum behind it.”

Krystian Kolondra, executive vice president for Browsers at Opera, has said the move is a bid to “accelerate the transition of cryptocurrencies from speculation and investment to being used for actual payments and transactions in our users’ daily lives,” with Hamel adding that:

“[Opera] believe[s] all browsers will eventually integrate some kind of wallet, which will enable new business models to emerge on the web.”

Opera first announced it would be integrating a built-in crypto wallet for its desktop browser in early August, after launching a mobile crypto wallet as part of its beta Opera for Android in July. In September, the firm released an interoperable “Labs” beta version for Android with integrated wallet, Web 3.0 and DApp functionality.

“Web 3.0” is a term that was initially coined to refer to the ambition for the development of a semantic internet, and is increasingly used to refer to the evolution of a more intelligent, open and distributed internet, which could involve the use of blockchain, decentralized computing and cryptocurrencies.

As previously reported, Opera partnered with blockchain advisory and financial services firm Ledger Capital this September to explore possible blockchain applications across its products and ecosystem.

Ethereum Hacks on the Rise Again as Price Remains Below $100

Hackers are continuing to find exposed mining rigs and wallets, which make easy targets for stealing ETH funds.

A fresh wave of hacks targeting Ethereum (ETH) holdings continues, despite the altcoin’s price trailing at 18-month lows, tech magazine ZDNet reported Dec. 10.

Citing research by cybercrime monitoring company Bad Packets LLC, the publication revealed that the downturn in ETH/USD has failed to stop malicious parties attempting to steal funds from miners and investors.

Scanning the network, hackers are trying to identify mining rigs and wallets with an exposed port 8545, which ultimately allows them to gain control and redirect ETH funds elsewhere.

“Despite the price of cryptocurrency crashing into the gutter, free money is still free, even if it’s pennies a day,” Bad Packets co-founder and security researcher Troy Mursch commented.

Cointelegraph originally reported on the Ether scanning phenomenon in June this year after one operation netted a reported $20 million in ETH.

Other incidents had occurred previously, joining a spate of various campaigns to divorce cryptocurrency holders from their wealth.

2018 has been a particularly bad year for so-called ‘cryptojacking’ attacks, which Bad Packets also monitors.

Cryptojackers attempt to remotely commandeer devices in order to mine or steal cryptocurrency, with detections rising almost 500 percent this year. “Because this threat is relatively new, many people do not understand it, its potential significance, or what to do about it,” a dedicated report on the problem by the Cyber Threat Alliance said in September.

Report: Court Ruling to Return Mistakenly Sent Cryptocurrency Could Set Precedent

A blog post from the University of Oxford Faculty of Law highlights the potential impact of a recent Canadian court ruling on lost or stolen crypto claims.

A Dec. 12 Business Law Blog post from the University of Oxford Faculty of Law notes possible repercussions for lost and stolen crypto claims following a case in a Canadian trial court earlier this year.

In the post, SAFE Frankfurt researcher Grygoriy Pustovit notes the case of Copytrack Pte Ltd v Wall. The superior trial court of British Columbia ruled that Ethereum (ETH) tokens, which were mistakenly sent by the plaintiff, Singapore blockchain startup Copytrack, to the defendant, Brian Wall, must be returned to Copytrack.

The defendant mistakenly received 530 Ethereum coins from Copytrack instead of 530 Copytrack (CPY) tokens that he was supposed to receive after participating in Copytrack’s initial coin offering (ICO). The Ethereum amounted to 495,000 Canadian dollars ($370,482), while the value of CPY tokens he intended to purchase was 780 Canadian dollars ($583) at the time.

“This precedent may have major repercussions for the enforcement of claims regarding lost or stolen cryptocurrency,” Pustovit claims, as the ruling allows the plaintiff to trace and recover tokens “in whatsoever hands those Ether Tokens may currently be held.”

As professional services for tracing digital assets develop, the rightful owners of certain assets could trace them on a public ledger and ostensibly recover tokens once they appear in an exchange’s wallet. Pustovit states that blockchains are not only governed by their code, but by the laws of concerned jurisdictions as well.

While noting that cross-border enforcement of varying national laws and regulations could prove difficult, the blog says that crypto businesses will likely comply with judgements in jurisdictions wherein they have strategic interests.

Pustovit also states that the Canadian court “missed the opportunity” to define the legal character of cryptocurrencies because it “could not be handled through summary judgment.” Since the defendant was deceased, “there would be no practical utility in sending this matter to trial.” The court therefore ruled the Ethereum tokens to simply be the property of the plaintiff and that they should be returned. Claims in conversion and detinue were left unsettled.

While the legal status of cryptocurrencies in case law remains hazy, “there is an increasing number of decisions recognizing that other intangible assets, e.g. funds, shares and mineral interests, may be subject to claims in conversion and detinue.”

Canada is reportedly one of the most crypto-friendly countries, with its favorable regulation of the industry, and low energy costs for crypto mining. In the summer of 2018, the Canadian government issued an official draft regulation for crypto exchanges and payment operators.

Ethereum (ETH) Futures Rumors Mount, As CBOE’s Bitcoin Foray Turns One

CBOE’s Bitcoin Foray Turns One

As noted by Tom Hearden, a senior trader at Skylands Capital, subsequently relayed through MarketWatch, one year and one day ago, the Chicago Board Options Exchange (CBOE Global Markets) made history, becoming one of the first financial institutions to launch a fully-fledged Bitcoin (BTC) product.

Now that crypto is in the midst of a bear market, might as well look back and reminisce… right?

This instrument was, of course, a BTC-backed futures contract that became an industry hot topic near-instantly. Still, in Ethereum World News’ original report on the matter, which seems decades old now, community members divulged that they were dissatisfied with the product’s launch, as the Chicago-based institution’s webpage crashes just eight minutes after the launch of the first bonafide BTC futures. Yet, during that day in history, December 11th, 2017, BTC purportedly rose from $14,500 to $15,700 in minutes, presumably due to the influx of interest that speculators expected.

In fact, spot and futures BTC rose so fast that CBOE, likely inundated with queries from investors worldwide, had to halt trading on its market… twice. And now, amid the market lull, catalyzed by the absence of Bitcoin bulls, CBOE’s enamorment with halting trade is as apparent as ever. Case in point, the institution had to adjust its “Lower Price Limit” percentage twice, when the futures price hit $3,160, the year-to-date low.

Mati Greenspan spoke to the aforementioned financial media outlet on the matter of the Bitcoin futures, lauding them as a resounding success: He wrote:

They’ve managed to open up the market to users who otherwise wouldn’t have access, so in that regard, I think they have been somewhat of a success. Not only did they allow people to go long, but it opened up short selling to a wider audience.

While the eToro in-house crypto analyst painted the product in a good light, as it broadened Bitcoin’s horizons, MarketWatch noted that CBOE data indicates that the product failed to catalyze an unparalleled influx of institutional money.

Bakkt, Nasdaq, and ErisX To All Launch Bitcoin Futures

Although CBOE’s in-house crypto instrument might not have garnered boatloads of investment interest, there remain a number of firms looking to unveil futures for Bitcoin, and reportedly even Ethereum.

As reported by Ethereum World News previously, Bakkt, a diverse crypto startup partnered with the Intercontinental Exchange, Starbucks, and Microsoft, has the intent to launch a physically-backed Bitcoin futures product by January 24th, 2019, in an industry first.

ErisX, backed by TD Ameritrade, issued a similar announcement, seemingly aiming to undermine its rival in Bakkt. Not much is known about this venture, but many expect that it will offer a product roster that mirrors or somewhat resembles that of Bakkt.

Most recently, Nasdaq, the world-renowned financial institution, divulged that it is working in collaboration with crypto-friendly VanEck, to bring “crypto 2.0 futures” to market, with the firm presumably looking at Ethereum and Bitcoin as supported assets. Bloomberg has revealed that Nasdaq is planning to publicly embark on its first notable crypto foray by Q1 of 2019, pending a green light from the U.S. CFTC.


Ethereum Product Rumored

Even with all this hype surrounding Bitcoin-centric futures, a new contender is expected, if not slated to emerge into crypto’s alternative investment vehicle scene. This, if you haven’t guessed already, is Ether (ETH), the native asset of the “world computer” that is the Ethereum Network.

Just recently, the U.S. Commodities Futures Trading Commission (CFTC) hinted that it is looking into ETH. In a statement, the prominent American financial regulator claimed that it was seeking the public’s opinion on digital currencies, most notably Ethereum. In a public release, the somewhat crypto-friendly body wrote:

The RFI [Request For Information] also seeks to understand similarities and distinctions between Ether and bitcoin, as well as Ether-specific opportunities, challenges, and risks.

It is believed that the entity is seeking feedback to precede its ruling on an Ether-backed vehicle, such as purported Ethereum futures contracts backed by CBOE. Yet, a number of crypto commentators recently took to Twitter to allude to the theory that if Ethereum-backed futures, even a non-physical instrument, goes live, the aforementioned blockchain’s native asset may actually fall, due to “rehypothecation” — a common sight in traditional financial industries.

Major Ethereum Software Client Upgrades in Preparation for Constantinople Hard Fork

The Go Ethereum software client has published a code upgrade that includes a list of new features, including an activation time for the Constantinople hard fork.


The Ethereum (ETH) Constantinople upgrade appears to be proceeding as planned, as a widely used Ethereum software client has published new code that includes a Constantinople activation time on GitHub Dec. 11.

The post reads that Geth, which stands for Go Ethereum, v1.8.20 is a special release that will “finally” enable the Constantinople hard fork on the Ethereum mainnet at block 7,080,000. Geth is one of the three original implementations of the Ethereum protocol. The description further states:

“It’s also our last planned release of the 1.8 family, meaning that we’ll start merging backwards incompatible changes onto master in preparation of Geth 1.9.0.”

Ethereum core developers agreed to launch the long-awaited Constantinople hard fork at block 7,080,000 on Friday, Dec. 7. The upcoming Constantinople hard fork comprises five separate Ethereum Improvement Proposals (EIPs) in order to soften the transition from proof-of-work (PoW) to the more energy efficient proof-of-stake (PoS) consensus algorithm.

PoS would fundamentally change the Ethereum blockchain by means of a host of new upgrades, which prevent any backwards compatibility. This means that nodes must either update synchronically with the entire system or carry on running as a separate blockchain entity.

The Friday agreement follows a decision to delay the Constantinople hard fork for late January 2019 due to a “consensus” issue that appeared during an upgrade trial on the Ropsten testnet in October.

Yesterday, Ethereum co-founder Vitalik Buterin declared that future blockchains with sharding based on PoS will be “thousands of times more efficient.” Buterin stated that, as scalability advances (driving fees down) and user experience gets better, non-financial applications will become “a bigger part of the story.” He also noted that blockchains are not about “cutting computational costs,” but are instead about increasing computational costs while decreasing “social costs.”

Bitcoin, Ripple, Ethereum, Stellar, EOS, Bitcoin Cash, Bitcoin SV, Litecoin, TRON, Cardano: Price Analysis, Dec. 12

The recent slump in markets has provided traders with a good buying opportunity, but a recovery may not come in the form of a dramatic vertical rally.

The views and opinions expressed here are solely those of the author and do not necessarily reflect the views of Cointelegraph. Every investment and trading move involves risk, you should conduct your own research when making a decision.

The market data is provided by the HitBTC exchange.

When markets were rising, the novice traders believed they can never go down, and one must only have the courage and patience to HODL. However, after this year’s nerve-racking correction, most of those same traders now believe that the cryptocurrencies are going to zero. They were wrong on the way up, and they are wrong again on the way down. The fundamentals are getting better and are pointing to a better future.

Mike Novogratz, former hedge fund manager and Goldman Sachs Group Inc. partner said that the markets are sober now, as the speculative mania is gone. He remains bullish and believes that Bitcoin is not going to zero, it is just in a “methadone clinic.”

The most popular twins in the crypto space, Tyler and Cameron Winklevoss, are also undeterred by the current bear market. They have launched a new mobile crypto trading app with various investment features. Their crypto exchange, Gemini plans to enter the Asian crypto space in 2019.

But not everyone is bullish about the future. Harvard University Professor of Economics and Public Policy Kenneth Rogoff believes that the long-term value of Bitcoin is “more likely to be $100 than $100,000,” as reported by The Guardian.

We, however, believe that the current fall is a good buying opportunity, but the traders should not expect a vertical rally. The markets are likely to form a large base before starting a new uptrend.


Bitcoin is currently trading inside a descending channel. The bulls have been attempting to defend the $3,500 mark for the past three days. A break of this first support will result in a retest of the Dec. 7 low of $3,329.05.


If the bulls hold $3,500, the BTC/USD pair might pull back to the resistance line of the channel, just below the 20-day EMA. We expect this level to act as a stiff resistance.

Though the moving averages continue to fall, the RSI has been forming a positive divergence for the past few days. This is a bullish sign. If the price climbs above the 20-day EMA, we can expect the pullback to reach the next overhead resistance of $5,000.

A failure to break out of the 20-day EMA, and a plunge below $3,329.05 will test the $3,000 threshold. If this support also breaks, the next support is way lower at $2416.52. However, we expect the leading digital currency to hold the $3,000–$3,500 zone, so we had recommended a buy in our previous analysis.


Since breaking down of the support at $0.33108, the bulls have been attempting to keep Ripple above the Dec. 7 low of $0.28600.


A break below $0.286 and the support line of the channel can result in a fall to the Aug. 14 low of $0.24508. If this support breaks, the next support is at $0.15.

If the bulls hold the support and break out of the 20-day EMA, we expect the XRP/USD pair to rally to the 50-day SMA. A sustained move above $0.4 will increase the probability of a rally to the top of the channel at $0.5. Therefore, we suggest traders hold on to their existing long positions.


Ethereum has been trading in a tight range of $83–$102.5 since breaking down of the previous support of $102.2.


The RSI has been forming a positive divergence, which increases the possibility of a pullback. On the upside, any recovery attempt will face resistance at $102.5, the 20-day EMA and at $130.5.

If the ETH/USD pair plummets below $83, the downtrend will resume. Its next lower target is $66. The traders can wait for a bullish pattern to develop before entering any positions.


Stellar is trying to pull back from the lows. It has broken out of the downtrend line, which shows some respite from the incessant selling. The recovery will gain strength if the price breaks out of $0.13427050. On the upside, the 20-day EMA and $0.184 will act as major hurdles.


On the other hand, if the XLM/USD pair turns down from the overhead resistance and breaks $0.10488320, the downtrend can extend to $0.08. The down sloping moving averages and the RSI in the oversold territory suggest that the downtrend remains. We shall wait for a new buy setup to form before proposing any trades in the pair.


EOS has broken out of the downtrend line, which suggests that the intensity of the selling has reduced. But the trend remains headed downward, as both moving averages are still falling, and the RSI is in the oversold zone.


If the bulls break out of the immediate resistance of $2.1733, the pullback can extend to the 20-day EMA, which is likely to act as a stiff resistance. A break above this can carry the EOS/USD pair to $3.8723.

If the next dip doesn’t break the low of $1.55, we can confirm that a bottom is in place. However, if the next dip breaks the Dec. 7 low, the digital currency can fall to $1.2. We suggest traders wait for a reversal pattern to form before entering any long positions.


Bitcoin Cash dipped below the Dec. 7 low of $94 and made a new year-to-date low on Dec. 11 at $92.13. This indicates a lack of buying even at the current levels.


Currently, the bulls are attempting to push the price back above $94. If successful, the BCH/USD pair will continue to trade in the range of $92.13–$115.61. Both moving averages are falling, and the RSI is deep in the oversold territory. This confirms that the trend is down with no signs of a reversal yet.

The first sign of buying will be when the bulls break out and close (UTC time frame) above $116. In such a case, the pullback can extend to the 20-day EMA. Though the digital currency has a history of vertical rallies, we suggest traders wait for buying to resume before attempting a trade in it.


While the other cryptocurrencies are showing signs of bottoming out, Bitcoin SV is facing selling at higher levels.


For the past five days, the BSV/USD pair has been falling gradually and has reached the bottom of the range. A break below the range can result in a retest of $38.528.

On the other hand, if the bulls bounce from the bottom of the range, we can expect the digital currency to reach the top of the range at $123.98. Trading inside a price range can be volatile, so we shall wait for a break out of the range before recommending a trade in it.


Litecoin has been consolidating close to the lows for the past five days. Though the price has stayed above the low of $23.1, it has not been able to move up. This shows a lack of buying at higher levels. The trend remains in favor of the bears as long as the price is below the downtrend line.


A return of buyers will be signaled when the LTC/USD pair sustains above the 20-day EMA. The RSI has formed a bullish divergence, which is a positive sign.

Aggressive traders can wait for the price to close above the 20-day EMA and establish long positions with a short-term target of $40. The stop loss can be placed at $23. The traders should keep the position size at only about 30 percent of usual because it is a countertrend move. If the digital currency slides below $23.1, it can reach $20.


TRON has formed a symmetrical triangle, which is usually a continuation pattern. However, in some cases it acts as a reversal pattern as well.


If the bears break below the triangle, the downtrend might resume. The pattern target of such a breakdown is $0.00554133. It has a minor support at $0.00844479, which can attract some buying.

Conversely, if the TRX/USD pair breaks out and closes (UTC time frame) above the triangle, it has a pattern target of $0.02055867. However, we believe $0.0183 will offer a stiff resistance. If the digital currency doesn’t break down or break out of the triangle within the next few days, the pattern will be invalidated.


Cardano has been consolidating close to the lows. It is currently facing resistance at $0.35. Any recovery is likely to face resistance at the 20-day EMA. If the bulls break out of this resistance, a rally to $0.456 and thereafter to the 50-day SMA is probable.

The RSI is developing a positive divergence, which is a bullish sign. But still, in a downtrend, traders should wait for the price to show an uptick before jumping in to buy because positive divergences turn out to be bear traps.


If the ADA/USD pair turns down from one of the overhead resistances and slides below $0.027237, the downtrend will resume. The next stop on the downside might be $0.025954. We can’t find any reliable buy setups yet, so we are not recommending a trade in it.

Developers Test Cross-Blockchain Protocol for One-Way ERC20-Bitcoin LN Atomic Swaps

An R&D lab at crypto startup TenX has demoed the use of its cross-blockchain protocol to transfer ERC20 tokens for Bitcoin (BTC) using the LN.

An R&D lab at crypto startup TenX has tested the use of its cross-blockchain interoperability protocol to transfer ERC20 tokens for Bitcoin (BTC) using the Lightning Network (LN). The news was reported on R&D lab CoBlox’s blog today, Dec. 12, in reference to the demo on Dec. 7.

As the blog post outlines, the technical challenge was to exchange ERC-20 tokens — which run on the Ethereum (ETH) platform but are not strictly “native” since they rely on invoking a smart contract to transfer ownership — for Bitcoin’s smallest transactable unit, known as “Satoshi,” using the second-layer scalability LN protocol.

Lightning Network is a second-layer solution to Bitcoin’s scalability issue, which uses Hashed Timelock Contracts (HTLCs) to open payment channels between users that keep the majority of transactions off-chain, turning to the underlying blockchain only to record the net results.

CoBlox’s previous Ethereum HTLC, as today’s post explains, was significantly simpler as it involved native assets. CoBlox has outlined their approach to find a solution for an ERC20 case, stating that the developers decided to “split the HTLC setup into two transactions” — “contract deployment” and “ERC20 transfer call” — but that they could not combine the two steps.

The post writes:

“The ERC20 transfer function uses msg.sender for authentication. However, calling transfer from a contract deployment sets msg.sender to the address of the yet to be deployed contract which obviously has no tokens!”

The post goes on to note that using “the Lightning Network for an atomic swap also has its quirks,” given that the solution relies on users creating invoices and paying them without necessarily “knowing about the underlying HTLCs.” However:

“An atomic swap cannot always be expressed through this model of invoices and payments. In LND, which is what we used for our PoC, receiving a payment requires an invoice which requires knowledge of the secret. As a result, we were only able to do ERC20 to Lightning and not the other way around. The invoice used in the swap can be found below.”

CoBlox states it is still “looking at ways” to resolve the limited directionality issue, and has therefore not included the results of its proof-of-concept (PoC) for ERC20 tokens as part of the open-source release of its COMIT network.

This summer, a study conducted by weekly crypto outlet Diar suggested that the Lightning Network may not be as effective at routing payments as believed, in particular when it comes to larger amounts. The report was rebuffed by the LN development team as being “poorly-researched and written,” with the full details of their criticisms outlined in a Cointelegraph analysis piece.
