Steem and Golos blocks are now synced and persisted in realtime.

Configuration

Glasnost now requires a PostgreSQL database.

You need to configure the following Postgres database parameters using the Docker ENV variables:

GLASNOST_DB
GLASNOST_DB_HOST
GLASNOST_DB_PORT
GLASNOST_DB_USERNAME
GLASNOST_DB_PASSWORD

Other parameters, such as PORT, STEEM_URL and GOLOS_URL, can be configured in the Docker file.

Changelog

golos_blocks and steem_blocks tables, indexes and schemas were added
blockchain synchronization subsystem and events handling has been improved and now handles block events
sync speed and perfomance was improved
various minor improvements and bugfixes
updated docker image

Development process

Glasnost is a single code base developed simultaneously both for Steem and Golos blockchains. Sustainable Glasnost development is made possible by generous support of Steem and Golos communities and @cyberfund program to support Golos open source ecosystem.
