We have retired orbiter.musicoin.org for it’s scalability issue. Now https://explorer.musicoin.org is up for public access but seems not enough. Anyone loves to run up an explorer instance, please reply here and we’d love to have a bounty for you. You can have customized domains by yourself, but must assure you have basic maintenance capability.
The bounty will be a reward for up-running continuously(2000MC/month). You will get a certificated badge to market with the endorsement from Musicoin Project.
