Why 1BTC should equal 10^8 satoshi ?

[KingOfTrolls]

This is the current GetBlockValue, providing a total money supply of 2099'9999'9769'0000 satoshis, halving the subsidy every 21'0000 blocks:

Code:

CAmount GetBlockValue(int nHeight, const CAmount &nFees) {
    int64_t nSubsidy = 50 * COIN;
    int halvings = nHeight / Params().SubsidyHalvingInterval();

    // Force block reward to zero when right shift is undefined.
    if (halvings >= 64)
        return nFees;

    // Subsidy is cut in half every 210,000 blocks which will occur approximately every 4 years.
    nSubsidy >>= halvings;

    return nSubsidy + nFees;
}

This is a proposed GetBlockValue, providing a total money supply of 2099'9999'9769'0000 satoshis, halving the subsidy every 21'0000 blocks, smoothly:

Code:

CAmount GetBlockValue(int nHeight, const CAmount &nFees) {
    int nHalvingInterval = Params().SubsidyHalvingInterval();
    int nHalvings = nHeight / nHalvingInterval;

    // Force subsidy to zero when right shift is undefined.
    if (nHalvings >= 64)
        return nFees;

    // Subsidy is cut in half every 210000 blocks which will occur approximately every 4 years.
    int64_t nSubsidy = COIN * 50 >> nHalvings;

    // Subsidy decreases linearily, beginning with 4/3, ending with 2/3 of the nominal value.
    nSubsidy *= nHalvingInterval * 4 - nHeight % nHalvingInterval * 2 - 1;
    nSubsidy += nHeight * 2 / nHalvingInterval % 2 * (nHalvingInterval * 3 - 1);
    nSubsidy /= nHalvingInterval * 3;

    return nSubsidy + nFees;
}

This is the corresponding hard fork proposal, with switchover scheduled for block 42'0000:

Code:

CAmount GetBlockValue(int nHeight, const CAmount &nFees) {
    int nHalvingInterval = Params().SubsidyHalvingInterval();
    int nHalvings = nHeight / nHalvingInterval;

    // Force subsidy to zero when right shift is undefined.
    if (nHalvings >= 64)
        return nFees;

    // Subsidy is cut in half every 210000 blocks which will occur approximately every 4 years.
    int64_t nSubsidy = COIN * 50 >> nHalvings;

    // Smoothened subsidy commences after the second halving, i.e. at block 420000.
    if (nHalvings >= 2) {
        // Subsidy decreases linearily, beginning with 4/3, ending with 2/3 of the nominal value.
        nSubsidy *= nHalvingInterval * 4 - nHeight % nHalvingInterval * 2 - 1;
        nSubsidy += nHeight * 2 / nHalvingInterval % 2 * (nHalvingInterval * 3 - 1);
        nSubsidy /= nHalvingInterval * 3;
    }

    return nSubsidy + nFees;
}

Edit: This is the final version.

This explanation is quite thorough. Maybe I should download the source myself and check it out. Thanks

I think this patch is probably a good idea.  I have no idea how to get community support for it though.

That remains to be seen
