The stats can be seen here:
Lets validate them using beem.
I added the script also to my beem github: blockactivity.py.

Just save the script as blocktivity.py and call it with the blockchain name (can be hive, steem or blurt).
Checking the blockchain activity
I started the script in three terminals to check the activity on hive, steem and blurt:
python3 blocktivity.py hive
python3 blocktivity.py steem
python3 blocktivity.py blurt
Results
The following table shows the obtained:
| Hive | Steem | Blurt | |
|---|---|---|---|
| Blocks | 28756 | 28466 | 28634 |
| Duration | 128.855 | 117.712 | 8016.021 |
| Blocks/s | 223.17 | 241.83 | 3.57 |
| Trx | 883929 | 195892 | 6942 |
| Ops | 894856 | 200968 | 7461 |
| Ratio of Trx to Bitcion Trx | 0.98 | 0.221 | 0.008 |
Hive
It seems that the activity shown at https://blocktivity.info/ counted every operation twice or it sums up the activity for 48 hours.
The block count reaches 99.84% of the maximum block count 28800.
Steem
The block count reaches 98.84% of the maximum block count 28800.
Blurt
The speed for receiving blocks from the API is really slow, it took 62 times longer as on hive.
The shown activity numbers are completely wrong. 549405 operations are reached in around 74 days and not in 24 hours.
The block count reaches 99.42% of the maximum block count 28800.
It seems that the bug was already found and will be fixed soon:
