The wind has suddenly brought a chill these days, and I have to close the windows tightly when I sleep at night. Early in the morning, I received a message from my mother: 'It's cooling down at home, what about your place? Remember to wear a thick coat.' In an instant, it felt like I was back to the days when I was told to wear long pants when I was in school. Good morning, the weather has changed, but care never changes. I have been following the progress of @ PortaltoBitcoin (PTB) recently, and it is quietly building a cross chain ecosystem that truly belongs to the native assets of Bitcoin. There are several key trends worth recording: 1/The main network now supports BTC ⇄ SOL atomic exchange No need for bridging, no dependence on encapsulated assets, 100% self managed cross chain The technology has been deployed and is gradually expanding to real-life application scenarios 2/Deflation mechanism has been activated Each cross chain transaction fee is partially used to destroy PTB The more frequent the transactions, the stronger the deflationary effect 3/The token economy model is gradually becoming clearer The current circulation ratio is about 16% -20%, and there is still a large amount that has not been released Staking+validator mechanism promotes long-term locking, LP incentives enhance liquidity 4/The market trend is in a critical range PTB has repeatedly tested the resistance level of 0.065, and the trading volume has significantly increased recently If effective breakthroughs can be made, it may open up new upward space 5/Continuous promotion of ecological construction Swap SDK、 The routing module and wallet plugin have been gradually opened for testing If mainstream wallets and aggregators are integrated in the future, the usage scenarios will be greatly expanded 6/Still need to maintain rational observation The throughput and stability of the main network still require large-scale verification Short term price fluctuations may be more severe Ecology is still in its early stages, and we need to be alert to excessive emotions Summary: PTB has moved from the "conceptual stage" to "practical verification" and is attempting to achieve true Bitcoin cross chain freedom through atomic exchange. If you are interested in the possibility of Bitcoin as the underlying asset of DeFi, this project is worth joining the watchlist. The next key focus is on: Does the main network transaction data continue to grow Can we stand firm at the key resistance level Is there mainstream infrastructure integrated into its SDK
