RGB and Taro, two protocols capable of putting tokens like stablecoins on Bitcoin, have taken different approaches to solving similar problems.
This is an opinion editorial by Kishin Kato, the founder of Trustless Services K.K., a Japanese Lightning Network research and development company.
Demand for stablecoins on Bitcoin is returning as the Lightning Network offers massive scalability advantages. Currently, users in emerging markets who want to transact and save in USD will settle for stablecoins on other chains, according to proponents. Putting my personal feelings about these other blockchains aside, I must acknowledge that bitcoin received in cheap, cross-border remittances cannot easily be sold for dollars while they reside in non-custodial Lightning channels.
