    A comment from Awabar Fukuoka
    We have acknowledged Nayuta for their high level of contribution to technology as well as our community. So, we were delighted when Nayuta first contacted us with their offer and we naturally agreed to the experimental launch. The role we play in this field experiment is rather small, but we hope it helps familiarize the community with the Lightning Network payment system.
