Verify blocktivity numbers for Hive and Blurt
@therealwolf was wondering on twitter on the high activity numbers on blocktivity.info for blurt:
https://twitter.com/therealwolf42/status/1340374495899561986
The stats can be seen here:
Lets validate them using [beem](https://github.com/holgern/beem).
I added the script also to my beem github: [blockactivity.py](https://github.com/holgern/beem/blob/master/examples/blockactivity.py).
```
import sys
from datetime import datetime, timedelta
import argparse
from timeit import default_timer as timer
import logging
from beem.blockchain import Blockchain
from beem.block import Block
from beem import Hive, Blurt, Steem
from beem.utils import parse_time
from beem.nodelist import NodeList
log = logging.getLogger(__name__)
logging.basicConfig(level=logging.INFO)
def parse_args(args=None):
d = 'Verify blocktivity by counting operations and trx for the last 24 hours.'
parser = argparse.ArgumentParser(description=d)
parser.add_argument('blockchain', type=str, nargs='?',
default=sys.stdin,
help='Blockchain (hive, blurt or steem)')
return parser.parse_args(args)
def main(args=None):
args = parse_args(args)
blockchain = args.blockchain
nodelist = NodeList()
if blockchain == "hive" or blockchain is None:
max_batch_size = 50
threading = False
thread_num = 16
block_debug = 1000
nodes = nodelist.get_hive_nodes()
blk_inst = Hive(node=nodes, num_retries=3, num_retries_call=3, timeout=30)
elif blockchain == "blurt":
max_batch_size = None
threading = False
thread_num = 8
block_debug = 20
nodes = ["https://api.blurt.blog", "https://rpc.blurtworld.com", "https://rpc.blurtworld.com"]
blk_inst = Blurt(node=nodes, num_retries=3, num_retries_call=3, timeout=30)
elif blockchain == "steem":
max_batch_size = 50
threading = False
thread_num = 16
block_debug = 1000
nodes = nodelist.get_steem_nodes()
blk_inst = Steem(node=nodes, num_retries=3, num_retries_call=3, timeout=30)
else:
raise Exception("Wrong parameter, can be hive, blurt or steem")
print(blk_inst)
block_count = 0
total_ops = 0
total_trx = 0
blocksperday = 20 * 60 * 24
blockchain = Blockchain(blockchain_instance=blk_inst)
last_block_id = blockchain.get_current_block_num() - blocksperday
last_block = Block(last_block_id, blockchain_instance=blk_inst)
stopTime = last_block.time() + timedelta(seconds=60 * 60 * 24)
start = timer()
for entry in blockchain.blocks(start=last_block_id, max_batch_size=max_batch_size, threading=threading, thread_num=thread_num):
block_count += 1
if "block" in entry:
trxs = entry["block"]["transactions"]
else:
trxs = entry["transactions"]
for tx in trxs:
total_trx += 1
for op in tx["operations"]:
total_ops += 1
if "block" in entry:
block_time = parse_time(entry["block"]["timestamp"])
else:
block_time = entry["timestamp"]
ops_per_day = total_ops / block_count * blocksperday
if block_count % (block_debug) == 0:
print("%d blocks remaining... estimated ops per day: %.1f" % (blocksperday - block_count, ops_per_day))
if block_time > stopTime:
break
duration = timer() - start
print("Received %.2f blocks/s." % (block_count / duration))
print("Bocks: %d, duration %.3f s" % (block_count, duration))
print("Operations per day: %d" % total_ops)
print("Trx per day: %d" % total_trx)
if __name__ == '__main__':
sys.exit(main())
```
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:
