Google reported on a new API reCAPTCHA v3, which will help to protect websites from bots. The system evaluates the user's key actions on a scale from 0.0 to 1.0 (the lowest rating means a bot, and the highest - a person) and provides data to the owner for making a decision. Google experts recommend adding it to several pages of the site, as reCAPTCHA v3 does not interfere with the user.

Google developers used the “Action” method in reCAPTCHA v3. Detailed statistics of user interaction with the site are represented in the admin panel. The site owner independently decides on actions with respect to users. The grading system allows you to:

  • set the period of time after which the API will require the user to verify from the user using the phone or two-factor authentication;
  • combine actions based on them with manually specified parameters for users;
  • use machine learning to train AI, which distinguishes a bot from a person.

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.
