After MIT Find Vulnerabilities, Medici Ventures Defends Blockchain Voting App Voatz

Jonathan Johnson, CEO of Overstock and president of Medici Ventures, has issued a statement supporting blockchain in voting in response to the technology’s vulnerabilities claims published on Feb. 13.

Emerging technologies got in the crosshairs of regulators when a mobile software application that had been devised to help calculate the total number of votes in the recent Iowa Democratic caucus reportedly malfunctioned, resulting in the Democratic Party having to delay its public reporting of last Monday’s results.

But does blockchain really fail when it comes to elections?

Following the Iowa caucus scandal, blockchain-based voting apps fell under scrutiny, which resulted in a Massachusetts Institute of Technology’s security analysis of Voatz, the self-styled first Internet voting application used in United States federal elections. 

The researchers claimed that they had found vulnerabilities in Voatz that enable “different kinds of adversaries to alter, stop, or expose a user’s vote, including a sidechannel attack in which a completely passive network adversary can potentially recover a user’s secret ballot.” 

As such, the authors of the analysis concluded that the app is not secure, adding that “our findings serve as a concrete illustration of the common wisdom against Internet voting, and of the importance of transparency to the legitimacy of elections.”

In the meantime, Voatz carried out its own analysis through the CISA Hunt and Incident Response Team (HIRT) to determine if there was evidence of targeted malicious activity in the app’s network. HIRT concluded:

“HIRT analysts did not detect threat actor behaviors or artifacts of past activities on the in-scope portions of the Voatz networks. HIRT identified some areas where defense-in-depth protections and configurations could be improved to help Voatz’s IT security personnel defend their enterprise network. HIRT commends Voatz for their proactive measures in the use of canaries, bug bounties, Shodan alerts, and active internal scanning and red teaming.”

Tech discussions run to extremes

In his Feb. 13 statement, Johnson backed Voatz, saying that it prevents voting fraud and safeguards the privacy of each voter. He outlined that recent speculations around technology in elections had run to extremes turning to an anti-technology and anti-learning stance. Johnson said:

“I firmly believe this undermines American progress. This false premise is shutting down our pursuit of piloting, testing and developing technologies that not only mitigate risks, but makes voting accessible for populations who cannot physically get to the polls.”

Earlier in February, another major blockchain-powered voting firm, Votem, pointed out that it is still not completely clear what function the app provided for the Iowa Caucus. Pete Martin, CEO of Votem, said in an email to Cointelegraph:

“Our assessment is that this was not truly mobile voting where a verifiably authenticated voter is casting a verifiable and auditable electronic encrypted ballot that is shuffled and publicly tallied. The Caucus is unique in that the voter’s identity is known, but in most cases the voters identity is separated from their ballot to protect their identity, all of which we detail in our “Proof of Vote” protocol.”

Binance CEO Changpeng Zhao believes that the upcoming Bitcoin halving has not been priced in to the digital asset’s current price action. The reduction in miner rewards will increase the cost of mining each Bitcoin, meaning, miners are unlikely to sell below their cost of production. 

Bitcoin’s supply will decrease with the halving but its demand has also been increasing, creating a situation where prices are likely to driven higher. Although CZ’s statement can be interpreted as bullish, the CEO personally believes that Bitcoin’s price might gravitate around $10,000 levels for a few more days as round numbers are known to act as psychological barriers.  

The traded volumes in major cryptocurrencies have skyrocketed in the past year and this shows greater participation by the traders. Currently, Tether (USDT) is the most frequently traded crypto asset, followed by Bitcoin and Ether (ETH). Liquidity…

Irish Drug Dealer Tells Police That Keys to $56M in Confiscated BTC Are Lost

Dubliner Clifton Collins, who was recently imprisoned for drug trafficking, claims that robbers took the keys to the $56 million in Bitcoin (BTC) Irish High Court had ruled should be confiscated.

After obtaining more than 6,000 BTC by 2017, Collins decided to insure himself against hackers by distributing the cryptocurrency across 12 newly created accounts. Thus, he transferred 500 BTC into each of them, the Irish Times reported on Feb. 21. As of press time, that would leave each wallet worth roughly $4.87 million.

A punishment for his own stupidity?

Collins then printed out the keys for all of his 12 BTC accounts onto a piece of paper, which he says he stored in an aluminium cap of his fishing rod case. This he stored in a house which he rented in County Galway, Ireland. However, when he was arrested for…

The Lightning Network’s (LN) configuration is becoming increasingly centralized, with multiple hubs being formed. This is the finding of a yet-to-be-reviewed research paper, released on pre-print site arXiv on Feb. 7.

A team of academics from Switzerland, France, Italy and Canada authored the paper. Jian Hong-Lin and Kevin Primicerio conducted the analysis, while others, including Blockstream Inc. researcher Christian Decker, designed the research.

Core-periphery model

The team gathered Lightning Network information for a period of 18 months from Jan. 18, 2018 to July 13, 2019. Researchers then analyzed the payment network in terms of its node and wealth distribution.

They discovered that the network showed high Gini coefficients both in terms of node centralization and wealth distribution. Notably, the values were found to rise as more nodes were added.

The distributions of Bitcoin (BTC) across every node in the network was found to be extremely…

Riot Blockchain, a Nasdaq-listed crypto firm in the United States, plans to sell its exchange to focus on Bitcoin (BTC) mining ahead of the halving.

According to an official announcement on Feb. 20, Riot has “opted to sunset further development of Riot’s U.S.-based digital currency exchange” in order to focus on cryptocurrency mining as part of its updated strategic priorities for 2020.

Following the announcement to shift its focus on Bitcoin mining, the company’s shares dropped more than 5%, trading at $1.40 at press time, according to CNBC data.

Industry experts disagree on the potential price impact of May 2020 Bitcoin halving — an event which will decrease block rewards on the Bitcoin blockchain. Changpeng Zhao, the CEO of major crypto exchange Binance, recently predicted that, since miners will have to…

Expert Says New Blockchain Regulation Should ‘Nudge’ Rather Than Push

single-image

bitbond bitcoin lending

Regulators should aim to influence public behavior rather than rule with an iron fist when it comes to emerging industries such as blockchain.

Two Israel-based academics, Hada Jabotinsky and Nassim Cohen argued this point in a new paper and accompanying brief, published to the University of Oxford Law Department blog on Feb. 21.

The paper proposes an approach that would result neither in an under-regulated free-for-all that leaves consumers vulnerable, nor in heavy-handed prohibitions that stifle technological progress.

Complex new technologies such as blockchain, cryptocurrencies, Internet of Things, and automated cars require ever higher levels of technological literacy. The paper states that, as the pace of innovation gathers speed, regulators struggle to grasp the implications of the products and inventions brought before them. 

What does a “nudge” involve?

The authors argue, “A nudge is ‘any aspect of the…

Bitcoin Price Drop Mirrors Last Golden Cross Which Led to 170% Gains

single-image

bitbond bitcoin lending

Bitcoin (BTC) may not see a 170% increase after its fifth “golden cross” price event, historical data suggests as markets stay down 8%.

Analysis of price movements since 2009 shows Bitcoin has had a total of ten “golden cross” and “death cross” moments in its lifespan. 

BTC price dip challenges December 2017

A “golden cross” is when BTC/USD sees its 50-day moving average rise to cross over its 200-day moving average. A “death cross” is the opposite. 

As Cointelegraph reported, hopes are currently high that the most recent golden cross will spark an identical reaction to the previous one — a 170% price surge in just two months. 

Overall, however, two out of four golden crosses have resulted in gains, while the other two in fact saw price losses. Similarly, some death crosses were followed by price gains.

Bitcoin traders continue to dig for answers after BTC/USD abruptly dropped $1,000 in…
