Privex Launches Steem Blockchain Database Service

in dev •  2 years ago 

What is SBDS?

SBDS stands for Steem Blockchain Database Service. It allows importing data from the STEEM blockchain into a MySQL database for fast and easy querying of data.

We did not create SBDS. It is an open source project created by Steemit Inc. developers (@sneak @layz3r @recrypto) and is available at

We run a PUBLIC SERVER, on high quality hardware for developers to use. SBDS requires fast SSDs, and over 400GB of space, making it moderately expensive to run for a small project.

Why should I use it?

As you can see, SBDS is much faster for querying large sets of data from the blockchain.

We recommend a hybrid approach to your application (as is done by Steemit Inc's Jussi system), take recent/realtime data from RPC via websockets, while querying older data via SBDS.

Server Specs

CPUIntel(R) Xeon(R) CPU E3-1270 v3
RAM32gb DDR3
DISKS2x480gb SSDs in RAID 0 (for epic speeds)

Connection Details



SBDS is BETA SOFTWARE. This means that it is not stable, and may sometimes stop syncing, or provide bad data. Please do not rely on it for anything mission critical. We'll do our best to keep it online, however it has hung randomly several times over the past few days.

We've found certain queries such as querying witness blocks extremely slow, and some tasks such as calculating post rewards are currently not possible. We hope that the SBDS developers work to improve these kind-of issues and make SBDS more versatile.

Connect to SBDS

We use MariaDB, which is mostly compatible with MySQL clients and libraries. In some cases you may experience issues, if you do, please try to use a MariaDB compatible client.

$ mysql -u steem -psteem -h steem

Nice to see that companies are paying attention to Steem ecosystem and are willing to make it even better.
In most cases you don't have to parse entire chain to get data you want and can query RPC methods ( but it is still pretty slow (700-1000ms) and not very flexible.
SBDS is way faster (100ms at most) and you can do basically everything with it.
Looking forward to using it at Busy!
Keep up the great work!

Good work.
I have local instances but IMHO it's still not ready to make it publicly available, but such pre-release as yours is still valuable as people would have time to get used to using it.
( @furion's node is no longer following a head block AFAIK )

This is amazing. Thanks for putting an updated SBDS instance public, it will be really useful and it a good showcase of what is coming from the official team

Interesting post, Can anyone explain what the program can do for a noob?

Is this server still working? Can't get a connect.
ERROR 2003 (HY000): Can't connect to MySQL server on '' (110 "Connection timed out")

Wow! This is so cool.

wow, this is huge. i will absolutely be coming to use for a witness server next year.

Nice post..this is helpful

Good work. Saved in the bookmarks to use it!! Very nice. Thanks

I have a problem to consult.
How to get the payout of each post?

Good job! I was waiting for mysql compatible service like years!

I noticed that the most recent transactions seems to be at 16th April.

Is that temporary, and the node is still being maintained, or is it proving too unreliable to keep up to date?

From what I heard sbds base simply sucks :( and gets desynced often, it is a huge problem for me to maintain my app because of that.

Thanks... I'm sticking with internal databases until SBDS and Hivemind are stable.
