Topic: Mining, date / block reward table till 2100 (is this correct ?) (Read 1023 times)

I added a table to the wiki with block #, reward, projected year, total BTC count, yearly increase rate, and more.

No. It's not correct, you've used floating point and suffered from numerical precision problems you also started at the wrong point, as you noted. The first block is trivially found, its coded into every copy of bitcoin. http://blockexplorer.com/b/0

Assuming the precision of bitcoin is not increased:

python one liner
print "".join(["%0.8f %d %0.8f\n"%(5000000000/2**x/float(1e8),(x+1)*210000,sum([5000000000/2**y*210000 for y in range(x+1)])/float(1e8)) for x in range(34)])

(make up your own dates, — any dates are going to be somewhat approximate)

I had no idea of the specific date when Bitcoin began so I approximated from today's block #.

Is this table correct ?  If so, could we add It to the wiki ?
