Could there be hyperinflation in Bitcoin?
As I understand it, this is by consensus, i.e. all the nodes in the network agree on this protocol.


No. The network doesn't vote to change itself. Read this: What can an attacker with 51% of hash power do?
Arguably, you could try to get a change to the bitcoin client implemented through astroturfing.

Here's how you'd increase monetary inflation.


Find this code:

int64 static GetBlockValue(int nHeight, int64 nFees)
{
    int64 nSubsidy = 50 * COIN;

    // Subsidy is cut in half every 210000 blocks, which will occur approximately every 4 years
    nSubsidy &gt;&gt;= (nHeight / 210000);

    return nSubsidy + nFees;
}

Change 50 to, I dunno, 100.
Convince everybody else to do the same thing. Not just a majority - everybody.
