Hi,

I'd like to revisit the discussion of the digest algorithm used in hashcash.

I believe migrating to new hashing algorithms as a policy would
significantly increase decentralization and hence security.

I believe the impact on existing miners could be made pleasant by gradually
moving the block reward from the previous hash to the next (such that both
are accepted with different rewards).  An appropriate rate could possibly
be calculated from the difficulty.

You could develop the frequency of introduction of new hashes such that
once present-day ASICs are effectively obsolete anyway due to competition,
new ones do not have time to develop.

I'm interested in hearing thoughts and concerns.

Karl Semich
