A major upgrade is definitely of great significance for a public chain, so I will summarize the latest updates of polkdot @ Polkadot. Similarly, it is of great significance for other private chains such as @ Arbitrum @ Aptos @ NEARProtocol @ 0xPolygon @ peaq @ injection. I will write a special article later to introduce other public chains: one ⃣ Frequency @ frequency_xyz parallel chain data explosion Frequency is a Polkadot parallel chain that provides support for decentralized social networks. Recently, its data has been very good, with over 400000 active users per month, which is much better than the user data of many projects! What makes frequency different from others? ① Running on Polkadot, inheriting shared security ② Separate identity from application ③ Quiet operation in the background without generating noise ④ Realize a scalable and interoperable social network two ⃣ SubWallet @ subwalletapp now supports native cross chain support SubWallet is the most widely used wallet in the polkdot ecosystem and now supports: BTC native ⇄ DOT native BTC native ⇄ USDC/USDT (Asset Center) One click redemption "makes SubWallet an integrated platform similar to MetaMask+cross chain aggregator, simplifying Polkadot ecosystem asset management and transaction processes three ⃣ Peaq @ peaq Ecological Major Update AquaSave has completed the second milestone of Peaq's DePIN funding program: ① Build a decentralized identity system for devices on the network using peaq ID ② Enable each device to sign its data transmission on Peaq using its identifier Peaq @ peaq Pledge Update: http://portal.peaq.xyz/portal/staking ① Reduce your staking without canceling all token staking ② Distinguish between active validators and reserve validators ③ The upper limit is 42 Summary: Polkdot's major update is coming soon, including significant changes in the token economy and underlying technology, which will definitely radiate Polkdot's ecological projects and be a great benefit. Stay tuned and there should be good opportunities!
