Research

Blockspace Labs is the research and development arm, at blockspacelabs.com. These pages describe its projects.

• Sub-1 sat/vB relay
  Live: the Blockspace Labs node relays and keeps transactions paying less than 1 sat/vB, on stock Bitcoin Core with minrelaytxfee=0.
• blockspace.to: spent sats
  Live, a product: an ord explorer and indexer that also tracks which sats have been spent, running a fork of ord with --index-spent-sats.
• Blockspace Token Indexer (BTI)
  Live: every byte of every block attributed to the tokens that bought it, in three books. It powers block.space.
• The byte census
  Live: every block's bytes, counted by region: base, witness and envelopes.
• Who holds blockspace
  Live: the holders of every token's bytes, ranked by address. It powers the block.space leaderboard.
• The blockspace price
  Live: asking prices per kilobyte of blockspace across marketplaces, from every listing that can be read. It powers blockspace.markets.
• 4 MB transaction relay
  Research: relaying transactions up to 4 MB, the whole block weight. Stock Bitcoin Core stops at 100 kvB, so it needs a patched node; none relays them here today.
• Blockspace expansion policy
  Research: the relay and consensus levers that change how much blockspace is usable and who can reach it, each measured effect beside the arguments for and against. Descriptive; it takes no side.
• Permanent bytes: what to store on Bitcoin, and how
  Research: every byte on Bitcoin is permanent and costly. What deserves that, and how is each byte best spent? Seven questions, each tied to the data that could answer it.
• Policy observatory
  Research: count the transactions mined each block that standard relay would refuse, and how much blockspace reaches miners off the standard relay path.
• Low-fee propagation
  Research: which sub-1 sat/vB transactions the Labs mempool keeps actually get mined, by which pools, and how long they wait.
• The sub-1 sat/vB share
  Research: hour by hour, how much of a mempool with no fee floor pays below 1 sat/vB, and what it would have paid at the default floor.
• Full-RBF in practice
  Research: count the replacements the Labs mempool sees with full-RBF on, and which of them reach blocks.
• The witness discount, by protocol
  Research: each token family's split of base and witness bytes, and what the discount saved it in fees.
• The envelope taxonomy
  Research: every way data is carried on Bitcoin (ord envelopes, Counterparty, OP_RETURN protocols, stamps), by bytes over time.
• Inscription permanence
  Research: how often inscribed sats are spent or move, and where they go.
• Lost sats
  Research: sats that coinbase transactions never claimed, so they exist in no output: where and when they were lost.
• Cursed inscriptions
  Research: which rules cursed each inscription, by height, and how the books bind them to sats.
• Testing the BVT
  Research: does the price per kilobyte track attributed bytes? A proposed empirical test of Blockspace Value Theory, an untested thesis.
• Blockspace Value Theory (Labs card)
  Research: the thesis behind the meter, in its own words a living document and an untested thesis.
• Fork and reorg watch
  Research: detect indexers that follow a stale tip or a fork, from the experience of an atomicals indexer stuck on an orphan at block 966,500.
• Litecoin and Dogecoin blockspace
  Research: Litecoin's and Dogecoin's blockspace measured the way block.space measures Bitcoin's. No Litecoin or Dogecoin node runs yet; the study starts when one does.
