Ethereum Classic’s 51 Percent Attack a Lesson For Altcoins

The now confirmed 51 percent attack on Ethereum Classic has put altcoins on notice. While reorg attacks are part and parcel of the risk of decentralized systems, a number of altcoin communities have taken steps to avoid such attacks on their digital assets. For others, the ETC attack should be a lesson for altcoins to secure their network before they suffer a similar fate.

As is well-documented, a 51 percent attack occurs when a malicious actor gains control of the majority of the hash power of a network. The majority rules in decentralized Proof of Work blockchains. As Coinbase reminded us, Satoshi Nakamoto’s original bitcoin whitepaper asserts that: “If a majority of CPU power is controlled by honest nodes, the honest chain will grow the fastest and outpace any competing chains.” The need for an honest majority is considered a known weakness of Proof of Work blockchains. Litecoin’s Charlie Lee, however, sees things differently, defending 51 percent vulnerability as a feature of decentralized blockchains, not a flaw: This is a thought-provoking observation. By definition, a decentralized cryptocurrency must be susceptible to 51% attacks whether by hashrate, stake, and/or other permissionlessly-acquirable resources. If a crypto can't be 51% attacked, it is permissioned and centralized. https://t.co/LRCVj5F0O1 — Charlie Lee [LTC] (@SatoshiLite) January 8, 2019 Alts Have Been Hit in the Not-too-Distant Past Within days of the ink drying on its May 2018 Pornhub deal, Verge XVG was hit with a 51 percent attack, losing $1.9 million USD through excessive mining by a bad actor. That came within about a month of an attack in early April when a malicious actor rapidly mined Verge blocks with spoofed timestamps–exploiting the same vulnerability. A week after that first attack, they were targeted again. All in all, the spring of 2018 saw 35 million XVG coins created ahead of schedule and sold off. May 2018 also saw controversial bitcoin fork Bitcoin Gold attacked, with exchanges stung for around $18 million after the double-spending was accomplished. And Vertcoin was hit in October last year–16 orphaned blocks suggesting a chain reorg had been accomplished through a 51 percent attack. Altcoins Strike Back Against 51 Percent Attack After a tumultuous June 2nd, on which it suffered three double-spend attacks for losses in excess of $120,000, Horizen–the crypto formerly known as ZenCash–upgraded its network to prevent miners from broadcasting long chains, which had caused the vulnerability. Komodo uses the bitcoin blockchain to store backups of its own blockchain. It also deploys a system it calls Delayed Proof of Work. In DPoW, it has 64 elected notary nodes who record a block hash from a block onto the bitcoin-held backup every ten minutes. Komodo aside, the ETC incident remains a lesson for altcoins. But the Threat Remains Real If two blockchains use the same algorithm, then the smaller one will always be susceptible to risk of an attack. And as crypto51 shows, sometimes hashrates are too low and prices sufficiently high for there to be an incentive to perform an attack. Defending and securing their blockchains is up to altcoin communities. Komodo’s creative approach to resolving security problems preemptively has been mimicked by five other blockchains. Perhaps it is time the entire altcoin ecosystem made a stronger effort to secure their blockchains and avoid more carnage. Have your say. Does the ETC 51 percent attack provide a lesson for altcoins to get organized before they get reorganized?

Coinbase Suspends Ethereum Classic Following 51 Percent Attack

Coinbase has ceased interactions with the Ethereum Classic (ETC) blockchain after the exchange detected a 51 percent attack on the network. Following the discovery of a “deep chain reorganization” of the ETC blockchain, Coinbase suspended Ethereum Classic withdrawals and deposits. Also Read: Major Mining Pools Have a ‘High Die-Off Rate’ Study Reveals Coinbase Stops Interacting With ETC Blockchain After Deep Chain Reorganization Coinbase has published a blog post titled “Ethereum Classic ETC is Currently Being 51% Attacked” detailing a malicious attack on the ETC network. The post states that on Jan. 5, 2019, Coinbase detected “a deep chain reorganization of the Ethereum Classic blockchain that included a double spend.” In order to safeguard customer funds, the exchange “immediately paused interactions with the ETC blockchain.” The exchange was alerted to the attack by its automated systems, after which the company’s on-call engineers responded and worked to confirm the report. Coinbase chose not to publicly post analysis pertaining to the attack earlier in order to avoid creating a “false alarm” that could have created premature or unnecessary market instability. The company also notes that traders who attempted to send or receive ETC using Coinbase’s platforms were unable to complete said transactions as a result of the response. Coinbase Yet to Re-Enable ETC Transactions Since the incident, Coinbase claims to have detected “12 additional reorganizations that included double spends,” totaling 219,500 ETC valued at approximately $1.1 million. The exchange notes that “a full blockchain analysis is beyond the scope” of its blog post, adding that further examination into “the addresses sending the double spend transactions, the history of sends/receives from the addresses, the block fields such as timestamp, and the subsequent movement of miner rewards from attack blocks may shed light on the threat actor or actors behind these attacks.” Coinbase is currently assessing the “safety” of re-enabling ETC transactions and will communicate with customers regarding updates to the exchange’s support for Ethereum Classic. The post asserts that “Coinbase was not the target of this double spend and no funds were lost.” What is your response to the recently increased prevalence of 51 percent attacks targeting altcoins?

Vertcoin Suffers A 51 Percent Attack

Vertcoin is a lesser known project, but it’s becoming more familiar for all the wrong reasons. You might not know it by looking at the price action, but Vertcoin (VTC) is currently under  a 51% attack, with  a wave of reorgs and double-spend activity currently unfolding. Coinbase Security Engineer Mark Nesbitt published a blog post about an ongoing investigation into nearly two dozen “deep chain reorganizations” in Vertcoin, more than half of which included “double spends of VTC” worth more than $100,000. Chain reorganizations are akin to the blockchain version of alternate timelines you see in superhero movies, only in real life, no one saves the day. The biggest reorg had a “depth of 307 blocks and a length of 310 blocks.” Vertcoin isn’t the first cryptocurrency to suffer a 51% attack, and it probably won’t be the last. Bitcoin Gold and Verge came under similar attacks this year, exposing the vulnerabilities in the Nakamoto consensus algorithm. As for Vertcoin, Nesbitt outlines four separate attacks, the most recent of which began on Nov. 29 and continues today.  The incident is comprised of four reorgs and double-spends were part of all of them. Some in the VTC community were quick to blame the developers, volunteers who are feverishly trying to fix the problem with an upcoming hard fork and who want to eliminate rented hash power and ASIC-fueled mining on the network. Vertcoin devs aren’t aware of any “culprit” or “victim.” Some people have complained that we have not said anything about the 51% attack. Well, some of us have been working on the solution. The rest of our team was taking time to create a response to help educate the public on such attacks. Below is that response. $VTC #Vertcoin https://t.co/QaQZibBmXv — Canen (@Canen01) December 4, 2018 Plenty of Blame to Go Around Coinbase’s Nesbitt, meanwhile, went for the jugular, linking ASIC resistance with the security of a cryptocurrency like Vertcoin. But as Satoshi Nakamoto stated in the white paper: “The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes.”  Nesbitt pointed to the ASIC resistant nature of Vertcoin: While a full exploration of ASIC resistance is out of scope of this article, the observations above strongly suggest that pursuit of ASIC-resistance in a coin is counterproductive to the coin’s security. Vertcoin is an ASIC-resistant project, but according to one of the developers VTC “is mined with public ASICs now,” which the team plans to fight with an upcoming hard fork dubbed Lyra2REv3. Vertcoin developer Eric Kubik disagreed with Nesbitt’s characterization of the facts, saying rather than “ASIC resistance” the issue is tied to NiceHash, which if true has been anything but nice to the project. NiceHash is a Slovenian marketplace for buying and selling hash power. The Reddit community was quick to blame ASICs, suggesting the ASIC-resistant project should have removed ASIC-powered hash power. Meanwhile, Vertcoin shares software developers with the MIT-DCI Lit Lightning Network, including Gert-Jaap Glasbergen, who explained on social media: This isn’t caused by the ASICs but by Nicehash. There’s too much hashrate for rent at too low a price resulting in zero capex and low opex to do attacks. Vertcoin devs are close to launching the fork, which is designed to “temporarily stop mining outsourceability.” The devs argue that while ASICs may bolster the security of the Bitcoin network, they have the opposite effect on smaller networks like Vertcoin. The team is sold out and say they “will NOT compromise on decentralization by implementing centralized controls and…will not give up on fighting ASICS.” In the interim, they’re urging investors to “protect yourself against double spends.” Vertcoin recently dedicated a podcast to a website that attaches the cost of a PoW 51% attack including VTC, which may have placed a target on the coin’s back.   The author is not invested in any digital currency mentioned in this article but is invested in other cryptocurrencies.    The post Vertcoin Suffers A 51 Percent Attack appeared first on Crypto Briefing.

It Costs $20 to Launch a 51 percent Attack on Einsteinium and Less than $200 to Force a Hard Fork in Feathercoin

There is this other side of crypto. It’s dark and full of dead coins. It keeps piling up every time ETH or BTC print lower. Though the market is expecting a rally with Ran Neur listing a couple of indicators to justify his bullish stand, Einsteinium coin creators and “community” should be having a hard time. Last year,around this time,BTC went from $6691 (Nov 11) to $20000 (Dec 17) in 5 weeks.This on the back of the expectation and launch of a cash settlement BTC futures contract. An ETF is a way bigger deal & requires actual purchase of BTC.2 looming SEC decision deadlines ahead. — Ran NeuNer (@cryptomanran) October 7, 2018 A daring user by the name Piracy1 is planning to launch a 51 percent attack on the network for demonstration purposes. His reasons he says is to “to show people how easy it is and maybe prompt developers to implement mitigations”. He adds saying “I also just want to talk about 51 percent attacks because I think they’re neat”. What’s more? The attack will be available for all to witness via Twitch. Einsteinium is gullible because it is a Bitcoin hard fork but uses Scrypt for hashing. There is deep corrosion of its value and hash rate. As it is, to attack the network for one hour will cost $20. Controversy Around the 51 percent Attack As controversial as it is, the user Piracy1 plan to raise collect donation and could launch another attack on Vertcoin. However, this wasn’t received well by user Ersiees who inquired about his overall motive. In a thread Ersiees asks: “What these attacks are about is stealing money, right? Is that your plan? Why do you want donations to steal something or if you don’t steal anything how will you change the chain?” Piracy1 said he his announcing this attack in advance for educational purposes and “people can choose to not accept any transaction as confirmed until the attack is over”. As usual, users didn’t take this lying down. Some elucidated their feelings saying Piracy1 action is pure fraud, outright theft and illegal. A user Chris_mc1 was particularly vocal saying: “Isn’t this massively illegal? You’re basically DoSing a network. Possibly theft as well!” But a user Koolba interjected saying: “On the contrary, you’re contributing to the success of the coin by dedicating your personal resources to increase the total hash rate. It’s not a denial of service, it’s explicitly providing the mining service that the coin is asking its participants to provide. Now using that temporary hash rate imbalance to issue an explicit double spend attack could be considered fraud. But that’s a totally separate.” Litecoin Cash and Others are Susceptible Despite the emotions, the hack will happen on Oct 13 but it could open up a Pandora’s box. Data from Crypto51 theorizes what it will cost to launch a 51 percent on a blockchain network. Should users buy hash rates from NiceHash and dedicate salvos at Bitcoin Interest, Litecoin Cash, PACcoin and Feathercoin, then it will cost them less than $200 to completely hard fork these chains. Do you think the attack will be successful? Is Piracy1 acting Maliciously? Let’s know in the comment section below.

‘Real Risk’: Blockstream Exec Warns Over Bitcoin Cash 51 Percent Attack

Bitcoin Cash (BCH) average hashrate over the past week has fallen below 8 percent of Bitcoin’s (BTC), while Blockstream compares the altcoin to a five-year-old Litecoin hard fork.  Feathercoin? Is That You? In comments on Twitter today, Blockstream VP solutions lead Warren Togami sounded the alarm over BCH — warning its low average hashrate placed investors at risk of double spend attacks from malicious parties. According to Togami, there currently exists a “real risk” of double spending, which would have a paralyzing effect on exchanges and buckle BCH’s already low liquidity. Togami had previously issued admonitory words on the altcoin in May, when hashrate circled 12 percent of Bitcoin and exchanges were crediting BCH transactions after just one network confirmation, a move he described as “terribly dangerous.” Now, the state of the BCH network is reminiscent of Feathercoin — a project which forked off from Litecoin in April 2013, only to lie dormant for several years afterward. Launching with a price just under $0.50 per token, after a 51 percent attack in June the same year, FTC collapsed, becoming worth less than one cent for the next three years. Historic parallel from 2013https://t.co/jUXqar7fzO1/ FTC forked from LTC, competed for scrypt hashes.2/ Like BCH, incompetent dev.3/ Experienced crippling diff swings, added difficulty smoothing.4* Huge reorg attack.5* "Solved" problem with centralization.* = Next for BCH? — Warren Togami (@wtogami) September 4, 2018 Centralization And ‘Incompetent Dev’ For Togami, the “parallels” with BCH are clear. “FTC forked from LTC, competed for scrypt hashes,” he continued, adding that “like BCH,” FTC had an “incompetent” developer. The difficulty volatility BCH has also grappled with marks a further similarity, along with the fork’s increased centralization relative to its genesis. A double spend attack, Togami considers, could be next. Well-known figures at Blockstream have often taken an active stance in rebuking Bitcoin Cash developers and proponents for their claims of superiority over Bitcoin itself. As Bitcoinist reported, CTO Samson Mow took US exchange Coinbase to task in July when it emerged an internal investigation into insider trading of BCH had found no evidence of wrongdoing.

Strike Three? Verge Suffers Third Suspected 51 Percent Attack

Verge (XVG), the privacy-focused cryptocurrency is the news once again as unconfirmed reports suggest that it has fallen victim to another 51 percent attack. If proven to be true, it will be the third of such attacks on the crypto’s blockchain since April. The previous two attacks resulted in the theft of $1 million and $1.8 million respectively. Details of the Suspected Hack On May 27, a Bitcointalk forum poster with the moniker “CHIEF56” called attention to a Verge blockchain address with some “odd” transactions. Upon closer examination, these transactions appeared to have strange timestamps that couldn’t be found on other explorers, signaling the possibility of an ongoing double spend attack. Other members of the forum posted addresses tied to the first hack, with some of them showing negative balances. According to CHIEF56, one of the addresses holds a total of 142,853,089 stolen XVG tokens. On May 29, “Ocminer,” the forum poster who identified the first attack in April, confirmed that there was indeed an attack. However, a look at the data provided by the Verge network shows no drop in difficulty for any of the five mining algorithms. The previous two attacks have taken control of mining algorithms to hijack the mining of blocks on the blockchain. XVG proponents point to the absence of abnormal block production rates in the last one week as proof that there hasn’t been any attack since May 22. At the time of this writing, no smoking gun evidence other than the assertions of a few Bitcointalk users has been provided. Bitcoinist will continue to monitor the situation. A Multitude of Problems Even if the reports of a third 51 percent attack turn out to be untrue, XVG is already facing a multitude of problems. Two confirmed high profile attacks using essentially the same method in the space of two months does not inspire confidence. After the second attack, the Verge development team created a patch to prevent further exploits. However, reports indicate that the patch was allegedly copied from Shield Currency, a little-known coin launched in November 2017. Some commentators say the “fix” is inadequate to solve the hacking problem. Weiss Cryptocurrency Ratings recently scored XVG a D+ and C- in both commercial and technical parameters, respectively. The price of XVG has dropped by more than 50 percent in the past month. Has Verge fallen victim to yet another 51 percent attack?  Can the beleaguered cryptocurrency recover from its latest travails? Let us know what you think in the comments below. Images courtesy of Verge Network, CoinMarketCap, AdobeStock The post Strike Three?

51 Percent Attack: Hackers Steals $18 Million in Bitcoin Gold (BTG) Tokens

Murphy’s Law states that “whatever can go wrong, will go wrong.” For Bitcoin Gold (BTG), this epigram appears to be spot on as the network recently fell victim to the dreaded 51 percent attack. Forensic Analysis of the BTG hack On May 18, Edward Iskra, the BTG communications director alerted the crypto community to the attack via a blog post on the Bitcoin Gold forum. According to Iskra: An unknown party with access to very large amounts of hashpower is trying to use ‘51% attacks’ to perform ‘double-spend’ attacks to steal money from Exchanges. We have been advising all exchanges to increase confirmations and carefully review large deposits. A 51 percent attack is no mean feat, even on a small blockchain as a significant amount of computing power is required to pull it off successfully. However, if an attacker were able to hijack a blockchain, combining it with a double-spend would monetize the effort, and this is precisely what the suspected BTG hacker did. The image above is the Bitcoin Gold address of the suspected hacker. The attacker sends a particular number of BTG tokens to an exchange, trades them for another coin and makes a withdrawal. The hacker then returns those same coins in his/her wallet, hence the double-spending problem. Thus, the attacker can spend and hold the same coins at the same time. Looking at the image above, if all 76 transactions were indeed part of the hack, then the hacker has stolen about $18 million based on the current BTG price. 51 Percent Attacks are All the Rage Now There have been no transactions since May 19. However, the hacker could theoretically continue the attack, especially if they still control 51 percent of the blockchain. According to Iskra, the onus is on exchange platforms to be vigilant against such attacks. He also urged them to increase the number of confirmations for large deposits. The BTG communications director also added: There is no risk to typical users or to existing funds being held. The only parties at risk are those currently accepting large payments directly from the attacker. Exchanges are the primary targets. Bitcoin Gold joins Verge and Monacoin as blockchains hacked within one crazy week for cryptocurrency networks. The Verge attacker gained control of two of the five mining algorithms, successfully mining 35 million XVG tokens valued at $1.75 million in only a few hours. Can BTG overcome its present predicament? Let us know your thoughts in the comment section below.

Researches from MIT, Stanford Set to Replace Bitcoin with Their Groundbreaking Crypto Project

CoinSpeaker Researches from MIT, Stanford Set to Replace Bitcoin with Their Groundbreaking Crypto Project Until now, everybody has been talking about Bitcoin, the most popular and widely used digital currency. However, Bitcoin is unable to process thousands of transactions a second. Researchers from the Massachusetts Institute of Technology (MIT), UC-Berkeley, Stanford University, Carnegie Mellon University, University of Southern California, and the University of Washington have decided to fix such a weakness and develop a crypto asset better than Bitcoin. The researchers are working together as Distributed Technology Research (DTR), a non-profit organization based in Switzerland and backed by hedge fund Pantera Capital. The first initiative of Distributed Technology Research is the Unit-e, a virtual coin that is expected to solve bitcoin’s scalability issues while holding true to a decentralized model and process transactions faster than even Visa or Mastercard. Babak Dastmaltschi, Chairman of the DTR Foundation Council, said: “The blockchain and digital currency markets are at an interesting crossroads, reminiscent of the inflection points reached when industries such as telecom and the internet were coming of age. These are transformative times. We are nearing the point where every person in the world is connected together. Advancements in distributed technologies will enable open networks, avoiding the need for centralized authorities. DTR was formed with the goal of enabling and supporting this revolution, and it is in this vein that we unveil Unit-e.” According to the press release, Unit-e will be able to process 10,000 transactions per second. That’s worlds away from the current average of between 3.3 and 7 transactions per second for Bitcoin and 10 to 30 transactions for Ethereum. Joey Krug, a member of the DTR Foundation Council and Co-Chief Investment Officer at Pantera Capital, believes that a lack of scalability is holding back cryptocurrency mass adoption. He said: “We are on the cusp of something where if this doesn’t scale relatively soon, it may be relegated to ideas that were nice but didn’t work in practice: more like 3D printing than the internet.” The project’s ideology is firmly rooted in transparency, with a belief in open-source, decentralized software developed in the public interest with inclusive decision-making. The core team of the project is based in Berlin. To solve the scalability problem, DTR has decided to develop the Unit-e with parameters very close to Bitcoin’s design, but many things will be improved. Gulia Fanti, DTR lead researcher and Assistant Professor of Electrical and Computer Engineering at Carnegie Mellon University, commented: “In the 10 years since Bitcoin first emerged, blockchains have developed from a novel idea to a field of academic research. Our approach is to first understand fundamental limits on blockchain performance, then to develop solutions that operate as close to these limits as possible, with results that are provable within a rigorous theoretical framework.” The launch of the Unit-e is planned for the second half of 2019.
