How Many Blocks and Total Rewards for a Steem Witness in the Past 24 Hours?

The blockchain is a public database, this shouldn’t be hard to find out. In this post we know how to call the Steem API to find out the witness that procduce each block and the reward (in VESTS) he/she collects for generating the block (mining).

Let’s create a database in SQLite - with the schema:

sqlite> .schema
CREATE TABLE witnessblocks (
witness text,
number integer,
vests real,
time text,
block integer,
constraint pkey primary key (block)
);
CREATE INDEX index_block on witnessblocks(block);
CREATE INDEX index_witness on witnessblocks(witness);
CREATE INDEX index_time on witnessblocks(time);
CREATE INDEX index_vests on witnessblocks(vests);
CREATE INDEX index_number on witnessblocks(number);

Then, we can run a SQL to find out the number of blocks and total rewards for each witness. Results are sorted by total rewards in SP (which can be computed by simply roughly divided by 1943 SP) - see this number at: https://steemyy.com

Query:

1	sqlite> select witness,count(1), sum(vests/1943.761) as total from witnessblocks where time >= date('now', '-24 hour') group by witness order by total desc limit 30;

Result (a bit surprising, more than expected, different than what the steemworld says @steemchiller): I double check the data and everything seems correct. My understanding is that a lot of misses are re-scheduled and that is why the TOP witnesses get more turns to produce blocks.
