What is known about Kathmandu? The upgrade increased the potential to support computation with layer 2 (L2) solutions and streamlined the block validation process to improve transaction throughput. The developers also included support for individual management for permanent testnets. The Kathmandu project was proposed in July by Tezos members and development companies Nomadic Labs, Marigold, TriliTech, Oxhead Alpha, Tarides, DaiLambda, and Functori & Tweag. It was later approved by the community through an on-chain governance process.
Tezos is a Layer 1 blockchain ecosystem with support for smart contracts and the Proof-of-Stake (PoS) consensus algorithm. Tokens and DeFi applications can be created on the platform. The network has built-in management mechanisms for upgrades, so it does not require hard forks. Tezos has the native token Tez (XTZ). As of September 24, 10:10 UTC, it is trading at $1,52, up by 3,32% in 24 hours, according to Binance. In June, Tether launched its USDT stablecoin on the Tezos blockchain platform.
