Verify blocktivity numbers for Hive and Blurt

@therealwolf was wondering on twitter on the high activity numbers on blocktivity.info for blurt:

The stats can be seen here:

blocktivity on 20.12.2020

Lets validate them using beem.
I added the script also to my beem github: 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
