Constantinople Hard Fork to Activate in Late February

In his announcement, Szilagyi explains that the activation will take place at block number 7,280.000, which is expected to be mined on Feb. 27, 2019. The upgrade will reportedly be implemented as “a single fork on mainnet and a post-Constantinople-fixup fork on the testnets to get them back in line feature wise with the main network.”The vulnerability purportedly allows a potential attacker to steal cryptocurrency from a smart contract on the network by repeatedly requesting funds from it while feeding it false data about the malicious actor’s actual ETH balance. In order to patch the loophole, the launch of the upgrade had been postponed until further notice.Once implemented, the improvements would purportedly fundamentally change the Ethereum blockchain, preventing any backwards compatibility — meaning that network nodes must either update synchronically with the entire system or carry on running as a separate blockchain entity.

10335 users upgraded their Parity Ethereum nodes, says core developer

The whole cryptocurrency community has been waiting for the Constantinople hard fork since 2017. Recently, the team announced that the update has been postponed for the second time. This is because of a potential attack that can take place after the hard fork occurs the Parity team and the Geth team released a new emergency version and asked all the node operators to updated to the new version immediately. The emergency version released by the Parity team is Parity Ethereum 2.2.7 – stable and Parity Ethereum 2.3.0 – beta. The emergency version released by Geth team is Byzantium Revert v1.8.21. This update, according to the initial announcement by Ethereum Foundation, is required to be done by miner, exchanges and node operator. They also stated that people only interacting with the Ethereum need not do anything including Ledger, Trezor, MyEtherWallet, MyCrypto, and Parity Signer.

ETH Buyers Not Out of Woods Yet

ETH price is currently struggling to settle above the $124-125 resistance area against the US Dollar.ETH price dropped towards the $118 support against the US Dollar. The ETH/USD pair found a lot of buyers near the $117-118 zone, resulting in a decent upside correction. The price jumped sharply above the $120, $124 and $127 levels. Buyers were successful in piercing the 50% Fib retracement level of the recent decline from the $130 swing high to $117 swing low. There was a spike above the 100 hourly simple moving average and $128. However, the price failed to stay above the $127 resistance and later declined. There was a rejection near the 76.4% Fib retracement level of the recent decline from the $130 swing high to $117 swing low. The price is currently trading below the $125 resistance and the 100 hourly simple moving average. Moreover, there is a new connecting bearish trend line formed with resistance at $127 on the hourly chart of ETH/USD.

After the two years of price-centric action in the cryptocurrency industry, 2019 might shift the focus towards the fundamentals. Until the community puts an emphasis on the foundational aspects of crypto, we believe that a sustained recovery is unlikely.The Winklevoss twins believe that stablecoins and tokenized securities will give a boost to the crypto space. Remaining positive on Bitcoin (BTC), they continue to hold the view that it is a better investment than gold.Vontobel bank, Switzerland’s third largest financial custody provider, has launched a digital custody product for institutional players. Large players like Vontobel don’t get into a space without studying it extensively. That leads us to believe that it is only a matter of time until institutional money starts trickling into the market.

The Ethereum Classic Attacker Has Sent a Bigger Message

One of the more disturbing side effects of the crypto market’s downturn is it has made it easier for malicious actors to launch 51-percent attacks, making that most fundamental of blockchain security breach more frequent.Crypto enthusiasts debate ad nausea about the principles of this or that chain’s design, and those debates are important. But if a permissionless blockchain doesn’t have a large enough community of users, developers and miners operating in a self-reinforcing manner of value creation and protection, they’re vulnerable.That was the takeaway this week when crypto exchange Coinbase announced it had detected a series of deep chain reorganizations within ethereum classic (ETC). Someone had accumulated a majority of the ETC network’s hashing power and had used that dominant position to alter past transactions, resulting in double spends of 219,500 ETC, which Coinbase estimated to be worth $1.1 million at the time.

Why NEO Co-Founder Erik Zhang Says Ethereum Will Overtake Bitcoin

NEO appears to be losing ground in the popularity contest, at least lately. In the glory days of 2017, the “Chinese Ethereum” was a top 10 cryptocurrency with unstoppable potential. NEO was touted as being faster, better, and capable of handling way more transactions than other major networks. The hype surrounding the project was palpable.Despite his reduced share of time in the spotlight, Zhang isn’t just the co-founder of NEO; he’s also a core developer. And he’s completely disinterested in the NEO price and the crypto market fluctuations in general.
“NEO’s vision of smart economy is composed of ‘smart contract,’ ‘digital identity,’ and ‘digital assets,’ of which ‘digital identity’ is a prerequisite for compliance and a feature of NEO,” he adds. “Digital identity is also the area NEO wishes to focus on to facilitate the development of the formal economy using blockchain technology.”

Bitcoin (BTC) May Bottom Soon, But Bull Run Unlikely

After a holiday hiatus, Ran NeuNer, the founder of OnChain Capital and the host of CNBC Africa’s “Crypto Trader” segment, brought on a number of leading crypto investors, who all did their best to forecast where Bitcoin (BTC) and this industry would be heading next.In the CNBC Africa segment, Pomp went on to add that while a bottom is likely inbound, there’s a low chance that BTC and other cryptocurrencies will embark on a drastic recovery during 2019. The decentralist, who has been overtly skeptical of banks, noted that instead of falling further, BTC may begin to range trade, potentially between $2,500 and $4,500 for much of 2019.He went on to draw attention to the Lightning Network, which many believe will single-handily catalyze global adoption of cryptocurrencies, most notably Bitcoin. Pomp noted that the scaling solution is one of the fastest-growing protocols regarding scalability and usability. The in-house Morgan Creek crypto bull then noted that Lightning will be one of the big stories of 2019, along with the growth of a strong retail product and the arrival of institutional participation.

Ethereum Price Weekly Analysis: ETH Could Accelerate Losses Below $121

This past week, ETH price tumbled below the $146 and $140 support levels against the US Dollar. The ETH/USD pair even traded below the $130 support and the 100 simple moving average (4-hours). The decline was such that the price tested the last swing low of $120-121. Later, the price started consolidating losses and traded in a range above the $121 level. An initial resistance is near the $128-129 zone (the previous support).Besides, the 23.6% Fib retracement level of the last decline from the $153 high to $121 low is also near the $128 area. Therefore, it won’t be easy for buyers to clear the $128-129 resistance zone. If there is an upside break above $128, the price may climb towards the $138 zone. The 100 simple moving average (4-hours) is positioned near the $138 area to prevent further gains. Moreover, the 50% Fib retracement level of the last decline from the $153 high to $121 low is at $137. Finally, there is a crucial bearish trend line formed with resistance at $138 on the 4-hours chart of ETH/USD. Therefore, the $128 and $138 levels are the main hurdles for buyers in the coming days.

ConsenSys Founder Joe Lubin Says The Next Killer App (Ethereum) is Already Here

Ethereum Devcon, the annual Ethereum developer meeting, has been a congregating spot for the industry’s brightest and most forward ideas since its conception. The conference’s fourth iteration, held in Prague, Czech Republic, saw some of the biggest names in the game talking about the industry’s future.One of them was Joe Lubin, the current CEO of ConsenSys and co-founder of Ethereum. In his speech, Lubin reviewed the state of the Ethereum ecosystem and brought forward some of the accomplishments made by its developers.While one could argue that Lubin’s praise for Ethereum is nothing short of biased, decentralization is the next killer app—one that’s meant to stay. Just as the Internetexperienced its ups and downs in the early 2000s, the blockchain industry is going through the cycle, ready to change the world as we know it.

Researchers Find Vulnerability for Bitcoin, Ethereum, and Ripple Digital Signatures in Faulty Implementations

Researchers recently identified vulnerabilities in cryptographic signatures for Bitcoin, Ethereum, and Ripple, that allowed attackers to calculate private keys and, consequently, steal any crypto in that wallet. In total, the researchers calculated hundreds of Bitcoin private keys and dozens of Ethereum, Ripple, SSH, and HTTPS private keys using this unique form of cryptanalytic attack.It is critical that the software signs each transaction with a different nonce, otherwise hackers can (rather easily) find and calculate the signers’ private key. There is even evidence that hackers continuously monitor the blockchain for these kinds of repeated nonces, extracting money from compromised keys.As stated in the paper, any non-uniformity in the generation of these signature nonces can reveal private key information. Given a sufficient number of signatures, hackers can compute private keys and gain access to a user’s wallet and drain its funds.
