I found an interesting public chain - Aeternity (ae), which has been continuously developed on GitHub for 7 years, and has completed 99.99% of the White Paper's functions. It supports multi-signature and GA, as well as domain name system, Oracle Machine, and State Channels natively integrated into the underlying system. The hyperchain has been 90% completed. After the hyperchain is launched, it may become the best and only L2 network on the BTC network and will surely shine in the future. #AE eos#AE
