The Shanghai Upgrade, which was initiated at epoch 56832 and completed at 4:17 UTC, is the most recent testnet upgrade of the Ethereum blockchain. It will signal the transition to a proof-of-stake network that is fully functional and enable validators to cash out rewards they have earned by adding or approving blocks to the blockchain. The purpose of the test on Sepolia was to provide developers a chance to practice withdrawals that will take place on the leading Ethereum network. Sepolia is the second of three testnets to go through this simulation, however, unlike the first, this testnet was closed, meaning that only the Ethereum core developers were responsible for running the validators there. The last testnet upgrade on Goerli is expected to happen in the upcoming weeks, possibly delaying the mainnet Shanghai Upgrade until April.
To further develop the “Japan Metaverse Economic Zone,” several significant Japanese technology, manufacturing, and financial companies are working together to build the interoperable metaverse structure RYUGUKOKU (TBD). The metaverse alliance wants to assist in creating the infrastructure that will allow businesses to take advantage of Web3 marketing, work reform, and consumer experience efforts. In addition to implementing “Auto-Learning Avatars,” “Pegasus World Kit,” and “Multi-Magic Passport” to enable identity and payment methods, the platform will act as a virtual world to connect users to various Web3 services developed by businesses and governmental organizations. The Digital Ministry of Japan has plans to establish a decentralized autonomous organization (DAO) to assist government agencies in accepting Web3 technology. Japan is working to include Web3 technology into its national agenda.
