This week, Elastos launched multiple upgrades around BeL2, BTCD, and PGP Chain. The BTCD stablecoin was successfully deployed to the ESC mainnet, and the arbitration process test was completed and public testing was launched. The PGP chain uses a dynamic BPoS consensus to ensure the continuity of blocks, and a Gas allocation mechanism is formulated. In terms of main chain upgrades, the "zero penalty" strategy was verified and multiple node synchronization issues were fixed to enhance system stability. The Elacity platform also iterated synchronously, launching a smart account system that supports Web2 operations, and fully optimizing the front and back ends to improve user experience. The overall ecosystem is showing a steady expansion trend.
