📝 Original message:To reiterate some of the points here. My problem with proof of stake is
twofold.
1. It requires permission of coin holders to enter into the system. This is
not true of proof of work. You may even attempt (though not successfully) a
proof of work with pencil and paper and submit the block from a regular
laptop if you so choose. Whether this level of permissionlessness is
necessary is up to individual risk tolerance etc. but it is definitely the
default preference of Bitcoin.
2. Proof of stake must have a trusted means of timestamping to regulate
overproduction of blocks. This introduction of trust is generally
considered to be a nonstarter in Bitcoin. Proof of Work regulates this by
making blocks fundamentally difficult to produce in the first place.
Like Jeremy, I’m always interested to learn about new attempts in consensus
algorithms, but the bar to clear is very high and proof of stake to date
has not proposed much less demonstrated a set of properties that is
consistent with Bitcoins objectives.
