According to the recent continuous threat intelligence monitoring of EOS DApp encountering transaction crowding attacks: EOS.WIN, FarmEOS, Shadow Dice, LuckBet, GameBet, Fishing, EOSDice, STACK DICE, ggeos and other well-known DApps have been breached one after another. The attack group ( floatingsnow, etc.) attacks are still going on. Before the EOS mainnet fundamentally solves such defects, SlowMist recommends that all DApps that use the random number scheme on the chain be suspended urgently and upgrade the risk control mechanism. For the sake of safety, it is strongly recommended that all competitive DApps adopt the off-chain random seed random number generation scheme recommended by EOS officials long ago.

Xiao Lei: The news that Russia is preparing to invest in Bitcoin is worthy of attention. Bitcoin is very much in line with the needs of the Russian government

Recently, Xiao Lei, a financial writer, issued an article saying that I personally think that the news that Russia is preparing to invest in Bitcoin is worthy of great attention. Although the entire Bitcoin pool currently has a market value of less than 100 billion U.S. dollars, it can still be used as an emergency for Russias important international trade. After ten years of operation, Bitcoin has become a super-sovereign currency similar to gold. Although there is no news about the purchase and holding of Bitcoin by the governments of major countries in the world, if you want to predict who will be the first among the governments of major countries in the world Will buy bitcoin, I think, this country must be Russia. Due to Russias single economic structure and aggressive diplomatic strategy, many solutions to problems are simple and crude. From the perspective of its problem-solving and strategic goals, Bitcoin is very much in line with the needs of the Russian government. As previously reported, Vladislav Ginko, a professor at the Russian Presidential Academy of National Economics and Public Administration, stated that the Kremlin will soon start investing heavily in Bitcoin as a way of avoiding new U.S. sanctions, and that this could happen within a few weeks. .
