16 months ago, we APAsia.tech introduced our first basic infrastructure servers to the BitShares network with support from Move Institute (non-profit), DAOStreet, and selected others. Our goal was to provide better global connectivity to users of the BitShares blockchain and its available dapps. For the first 9 months we were privately funded, and finally the first worker proposal was authored, presented to, then voted for by stakeholders in August 2018. We were operating a constant minimum of 20 BitShares publicly available API nodes around the world.

The previous worker provided these outcomes over 6 months (+ 1 month granted additionally):

  • Minimum 80% uptime (our score on the end of the worker: 91.27%)
  • Upgrade and redeploy nodes at the beginning of the worker + DDOS protection where available
  • Proper management of cost optimizations (start $3380/month -> average last 3 months ~$1500/month)
  • 2 status pages (1 was delivered to public, 1 remained in private development)
  • Unspent funds from previous worker (Asked: 25,500.00 bitUSD, Available Balance: 7,994.05 bitUSD /after paid 7th month)

Worker Intent

To continue providing reliable and affordable infrastructure with not less than 25 nodes on the BitShares blockchain for another 12 months, and with the addition of exotic and limited locations to current API infrastructure. In addition, 3 baremetal instances are being deployed to those exotic locations. With this worker BitShares will be better branded and easily recognized, since one suggestion is to move all the API nodes from 3rd party domains to the bitshares.org domain. We also plan to provide more API’s in Canada, Russia and Australia - where we saw increased activitity during the last worker. Locations such as EU and US are already covered.

(re)Launch of Infrastructure requires:

  • Approval of this proposal
  • 5 Business days to shift all 3rd party domains to bitshares.org subdomains, purchase and deploy new SSL certificates for bitshares.org.
  • Acknowledgment from Stakeholders that this worker and its Public API nodes are for non-commercial USE only (limits are configured on some of the nodes).
  • Acknowledgment from Stakeholders that this worker has a management fee.

Status Pages

  • https://status.apasia.tech (production)
  • https://apasia.tech/demo1/ (development)


  • Update domains and bitshares.org dns for presented changes in this worker
  • Maintain uptime tracking/monitoring through status.apasia.tech on all nodes from this Worker with a start date from the date the Worker gets approved.
  • Continue maintenance and weekly backup of fully synced default API blockchain database for easier/faster replay.
  • Target of 90% uptime (avg of all nodes in this worker) on a monthly basis.
  • Provision 3 baremetal instances (property of AP Asia Tech Co., LTD.) to 3 locations (Thailand, S. America, Africa) within 60 business days from the day worker becomes active.
  • Maintain and monitor all nodes through status.bitshares.org (coming as part of the website bitshares.org)
  • Maintain GitHub resources for pre-compiled BitShares API node with default config and backup system.
  • Research on Grafana interface for deployment and possible integration for infrastructure of this worker. (Thanks to @xeroc for initial demo, development and introduction of Grafana to Community this year)
  • Re-deploy master nodes on each continent as load balancers/entry points for improved public usage/access to the API.

More nodes will be added/removed in the most economical manner preserving best functionality and global API availability.
