Is there a library to know the number of bitcoin mined at a given block number ?

There is a fixed rate for how many bitcoins are mined each block. The block reward halves every 210,000 blocks, see Controlled Supply.

Here is a short term bitcoin distribution projection from the Bitcoin Wiki:

To calculate the total coins for a given block, try:

coins.py

block = 210000 * 10
totalCoins = 0

subsidy = 50.0
for i in range(1,block):
    if(i%210000 == 0):
        subsidy = subsidy / 2
    totalCoins += subsidy
    #print i, subsidy, totalCoins

print totalCoins

  • Thanks for you answer, I'm looking for the (pseudo) code that would generate this array. – franck Aug 10 at 7:02
  • Just added some code and a project that might be helpful – JBaczuk Aug 10 at 13:12
