Why Bitcoin Unlimited’s “Emergent Consensus” Is a Gamble
The central idea behind Bitcoin Unlimited — specified in “Bitcoin Unlimited Improvement Proposal 001” (BUIP001) — is to hand control of Bitcoin’s block size limit to users and miners. Or perhaps more accurately: to make this control more explicit and easier to handle.
But as explained in “How Bitcoin Unlimited Users May End Up on Different Blockchains,” BUIP001 does not include a technical consensus mechanism as reliable as in Bitcoin’s current consensus rules.
