The researchers from MIT Media Lab Digital Currency Initiative (DCI) report on the vulnerability found in IOTA cryptographic hash function. IOTA team provides its customers with this information via their social media:

As reported, the IOTA developers themselves agree with the conclusions of DCI only partially. At the same time, the report says that the creators of the cryptocurrency have already released a corresponding patch, eliminating the identified shortcomings. 

Neha Narula, Director and Digital Currency Initiative at the MIT Media Lab, believes that thanks to the newly discovered vulnerability of IOTA, attackers could destroy or steal users' funds.

You might think that IOTA, a cryptocurrency worth over a billion dollars, and working with organizations like Microsoft, University College London, Innogy, and Bosch, BNY Mellon, Cisco, and Foxconn (through the Trusted IOT Alliance) would not have fairly obvious vulnerabilities, but unfortunately, that’s not the case.

Blockchain-based New Zealand-based research firm Brave New Coin (BNC) has unveiled a new system for measuring the mood of the Bitcoin community based on Twitter messages.

According to BNC, the new Twitter Sentiment rating system analyzes over 34 million BTC-related Twitter posts each week. The company uses artificial intelligence (AI) algorithms that look for records containing the words bitcoin, $ BTC and BTC and others.

BNC notes that user sentiment continues to be a “significant” factor in the price and dynamics of digital assets, and a new technique has been developed to track these sentiments. According to the BNC, it took 18 months to launch the Bitcoin Twitter Sentiment. The data obtained is divided into seven categories - Opinion, Technical Information, Inside the Network, Advertising, Bots, Macros and Hacking.

For the week ending January 17, the most common entries were in the Opinion category - their number was 30.42% of all data received. In second place was the category Technical Information, and in third inside the network (includes information on mining and hashrate).

BNC spokeswoman Pierre Ansaldi said that during the first quarter of this year, the company will also launch community sentiment analysis tools for other crypto assets.
