I can't remember who I saw discussing this idea. Might have been Vitalik
Buterin?
Yes, he described it in an article a couple of months ago:
http://blog.ethereum.org/2014/01/15/slasher-a-punitive-proof-of-stake-algorithm/
but it is an old idea.
For example, I've mentioned punishment of this
Please be aware that your emails are being spamfoldered by Gmail. This is
because Yahoo has enabled DMARC enforcement for mail sent from Yahoo and
that renders it incompatible with Sourceforge mailing lists.
There are two fixes:
1) Don't use Yahoo.
2) The real fix which is, we should stop using
There's no need to be confrontational. I don't think anyone here objects
to the basic concept of proof-of-stake. Some people, myself included,
have proposed protocols which involve some sort of proof of stake
mechanism, and the idea itself originated as a mechanism for eliminating
checkpoints,
What about using fraud proofs? Your coinbase only matures if nobody publishes
proof that you signed a competing block.
Then something is at least at stake. When it's your chance to sign a block,
attempting to sign and publish more than one at the same height reliably
punishes you (you
That makes double-spends trivially easy: sign two blocks, withholding
one. Then at a later point in time reveal the second signed block
(demonstrating your own fraud) and force a reorg.

Who said anything about a re-org? The original block remains valid, your block
reward is just zero, upon maturity, in light of a valid fraud proof.
ie. the coinbase confiscation that I was just arguing against in another
thread :P but of course here based on cryptographic proof, not human
Do it. Someone will scream harm. The loudest voices screaming how it would
be harmful are doing the most harm.
The only way to know is build it, and test it. If the network breaks, then
it is better we find out sooner rather than later.
My only suggestion is call it 'bitstake' or something to
My understanding is that sidechains require merged mining support and that
sidechains create no coinbase transactions themselves. When Bitcoin Core
supports the two-way peg then I would update my source code branch to
incorporate that or any other change that is released. Ideally, when
Hello all.
I understand that Proof-of-Stake as a replacement for Proof-of-Work is a
prohibited yet disputed change to Bitcoin Core. I would like to create a
Bitcoin branch that provides a sandboxed testbed for researching the best PoS
implementations. In the years to come, perhaps
