Subject: [Bitcoin-development] Punishing empty blocks?
Date: Thu, 24 May 2012 12:33:12 -0400 [thread overview]
Message-ID: <CA+8xBpdBe4yR6xkCODL6JQ41Gyx9eWcGGGvcQVt7DCmaEnAhbg@mail.gmail.com> (raw)
There appears to be some non-trivial mining power devoted to mining
empty blocks. Even with satoshi's key observation -- hash a fixed
80-byte header, not the entire block -- some miners still find it
easier to mine empty blocks, rather than watch the network for new
transactions.
Therefore I was wondering what people thought about a client
implementation change:
- Do not store or relay empty blocks, if time since last block < X
(where X = 60 minutes, perhaps)
or even stronger,
- Ensure latest block includes at least X percent of mempool
unconfirmed TXs
The former is easier to implement, though there is the danger that
no-TX miners simply include a statically generated transaction or two.
The latter might be considered problematic, as it might refuse to
relay quickly found blocks.
Comments? It wouldn't be a problem if these no-TX blocks were not
already getting frequent (1 in 20).
