General Proof-of-Work chain for tests and stuff
I was inspired by one of the assignments in the below reference lecture from MIT Open Courseware:
The basic idea was students had to submit a message which included
any message they want, the previous message's hash, and a nonce
such that when you has the input info it would produce some leading zeros.
Exactly how mining blocks in Bitcoin works.
How To Use
API_URL = "https://www.madebyozzy.com/powchain/api"
hash the data:
height + hash + message + nonce
Current difficulty: "1f0000f0"

message = "https://twitter.com/coolshoeshine2"
bits = 0x1f0000f0
# calculate difficulty from bits
exponent = bits >> 24
mantissa = bits & 0x00FFFFFF
diff = mantissa << (8 * (exponent - 3))
diffInBytes = diff.to_bytes(32, 'big')
# request last block info from url
API_URL = "https://www.madebyozzy.com/powchain/api"
response = requests.get(API_URL)
json_string = response.text
block = json.loads(json_string)
# get data from last block
height = block['height'] + 1
prev_hash = block['hash']
# loop through all nonces to find one below difficulty
nonce = 0
startTime = time.time()
while nonce <= 0xFFFFFFFF:
# construct new header
header = (struct.pack(" 0):
currTime = time.time()
timeDiff = currTime - startTime
hashesPerSecond = nonce / timeDiff
print('nonce: %d \t hashesPerSec: %f' % (nonce, hashesPerSecond))
# check if digest is below difficulty
if (reversedDigest < diffInBytes):
print(nonce)
print('Success!')
# send this info to the server
payload = {
"nonce": nonce,
"message": message,
}
response = requests.post(API_URL, data=payload)
print(response.text)
# print how long it took
currTime = time.time()
timeDiff = currTime - startTime
print("elapsed time (seconds):", timeDiff)
break
# increment nonce
nonce += 1
GET returns a json string with parameters height and hash.
Example:
{"height": 5, "hash": "00000b7dfca2b1654932e8afa2a816c7b22ffa4847e4985a13c8651c17caec21"}
message can be any string you want (max 160 characters).
nonce is any 32 bit integer which allows the above hash to
be below the target difficulty.
Once you find a suitable nonce:
POST that data to the API_URL with a json string.
Example:
{"nonce": 0, "message": "your custom message here"}
If your data meets the target difficulty then it will be added to the chain!
