Title: Mining, date / block reward table till 2100 (is this correct ?) Post by: Transisto on August 08, 2011, 06:05:40 PM 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 ?

If so, could we add It to the wiki ? 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)]) 50.00000000 0210000 10500000.00000000 25.00000000 0420000 15750000.00000000 12.50000000 0630000 18375000.00000000 06.25000000 0840000 19687500.00000000 03.12500000 1050000 20343750.00000000 01.56250000 1260000 20671875.00000000 00.78125000 1470000 20835937.50000000 00.39062500 1680000 20917968.75000000 00.19531250 1890000 20958984.37500000 00.09765625 2100000 20979492.18750000 00.04882812 2310000 20989746.09270000 00.02441406 2520000 20994873.04530000 00.01220703 2730000 20997436.52160000 00.00610351 2940000 20998718.25870000 00.00305175 3150000 20999359.12620000 00.00152587 3360000 20999679.55890000 00.00076293 3570000 20999839.77420000 00.00038146 3780000 20999919.88080000 00.00019073 3990000 20999959.93410000 00.00009536 4200000 20999979.95970000 00.00004768 4410000 20999989.97250000 00.00002384 4620000 20999994.97890000 00.00001192 4830000 20999997.48210000 00.00000596 5040000 20999998.73370000 00.00000298 5250000 20999999.35950000 00.00000149 5460000 20999999.67240000 00.00000074 5670000 20999999.82780000 00.00000037 5880000 20999999.90550000 00.00000018 6090000 20999999.94330000 00.00000009 6300000 20999999.96220000 00.00000004 6510000 20999999.97060000 00.00000002 6720000 20999999.97480000 00.00000001 6930000 20999999.97690000 00.00000000 7140000 20999999.97690000 (make up your own dates, — any dates are going to be somewhat approximate) Title: Re: Mining, date / block reward table till 2100 (is this correct ?) Post by: bitrick on August 15, 2011, 09:16:20 PM I added a table to the wiki with block #, reward, projected year, total BTC count, yearly increase rate, and more. http://en.bitcoin.it/wiki/Controlled_inflation#Projected_Bitcoins_Short_Term (http://en.bitcoin.it/wiki/Controlled_inflation#Projected_Bitcoins_Short_Term) |
