New and updated pageshttps://blockspace.wiki/2026-10-20T00:00:00ZBlockspace Holdingshttps://blockspace.wiki/timeline/2026-10-20T00:00:00Z

Dated, sourced events, the estate's launches and Bitcoin's own milestones.

https://blockspace.wiki/sources/2026-10-20T00:00:00Z

The bibliography, every document, spec and data source the wiki cites, and which pages cite it.

https://blockspace.wiki/research/witness-discount-by-protocol/2026-10-20T00:00:00Z

Research: each token family's split of base and witness bytes, and what the discount saved it in fees.

https://blockspace.wiki/research/who-holds-blockspace/2026-10-20T00:00:00Z

Live: the holders of every token's bytes, ranked by address. It powers the block.space leaderboard.

https://blockspace.wiki/research/testing-the-bvt/2026-10-20T00:00:00Z

Research: does the price per kilobyte track attributed bytes? A proposed empirical test of Blockspace Value Theory, an untested thesis.

https://blockspace.wiki/research/sub-1-sat-vb-share/2026-10-20T00:00:00Z

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.

https://blockspace.wiki/research/sub-1-sat-vb-relay/2026-10-20T00:00:00Z

Live: the Blockspace Labs node relays and keeps transactions paying less than 1 sat/vB, on stock Bitcoin Core with minrelaytxfee=0.

https://blockspace.wiki/research/policy-observatory/2026-10-20T00:00:00Z

Research: count the transactions mined each block that standard relay would refuse, and how much blockspace reaches miners off the standard relay path.

https://blockspace.wiki/research/permanent-bytes/2026-10-20T00:00:00Z

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.

https://blockspace.wiki/research/low-fee-propagation/2026-10-20T00:00:00Z

Research: which sub-1 sat/vB transactions the Labs mempool keeps actually get mined, by which pools, and how long they wait.

https://blockspace.wiki/research/lost-sats/2026-10-20T00:00:00Z

Research: sats that coinbase transactions never claimed, so they exist in no output: where and when they were lost.

https://blockspace.wiki/research/litecoin-and-dogecoin-blockspace/2026-10-20T00:00:00Z

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.

https://blockspace.wiki/research/inscription-permanence/2026-10-20T00:00:00Z

Research: how often inscribed sats are spent or move, and where they go.

https://blockspace.wiki/research/full-rbf-in-practice/2026-10-20T00:00:00Z

Research: count the replacements the Labs mempool sees with full-RBF on, and which of them reach blocks.

https://blockspace.wiki/research/fork-and-reorg-watch/2026-10-20T00:00:00Z

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.

https://blockspace.wiki/research/envelope-taxonomy/2026-10-20T00:00:00Z

Research: every way data is carried on Bitcoin (ord envelopes, Counterparty, OP_RETURN protocols, stamps), by bytes over time.

https://blockspace.wiki/research/cursed-inscriptions/2026-10-20T00:00:00Z

Research: which rules cursed each inscription, by height, and how the books bind them to sats.

https://blockspace.wiki/research/byte-census/2026-10-20T00:00:00Z

Live: every block's bytes, counted by region: base, witness and envelopes.

https://blockspace.wiki/research/blockspace-value-theory/2026-10-20T00:00:00Z

Research: the thesis behind the meter, in its own words a living document and an untested thesis.

https://blockspace.wiki/research/blockspace-token-indexer/2026-10-20T00:00:00Z

Live: every byte of every block attributed to the tokens that bought it, in three books. It powers block.space.

https://blockspace.wiki/research/blockspace-to-spent-sats/2026-10-20T00:00:00Z

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.

https://blockspace.wiki/research/blockspace-price/2026-10-20T00:00:00Z

Live: asking prices per kilobyte of blockspace across marketplaces, from every listing that can be read. It powers blockspace.markets.

https://blockspace.wiki/research/blockspace-expansion-policy/2026-10-20T00:00:00Z

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.

https://blockspace.wiki/research/4mb-transaction-relay/2026-10-20T00:00:00Z

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.

https://blockspace.wiki/research/2026-10-20T00:00:00Z

Blockspace Labs projects, one short page each, linked to blockspacelabs.com.

https://blockspace.wiki/protocols/tap/2026-10-20T00:00:00Z

TAP ticks and DMT, catalogued through tap-reader, a mirror of Trac's feed, with two hops of derived trust.

https://blockspace.wiki/protocols/src-20/2026-10-20T00:00:00Z

SRC-20 ticks written in the Stamps carriers, and SRC-101 names, both catalogued by the stamps adapter.

https://blockspace.wiki/protocols/spool/2026-10-20T00:00:00Z

ascribe's edition registry in OP_RETURN, from 2014 to 2017: editions are tokens, pieces are labels, and fuel transactions are enablers.

https://blockspace.wiki/protocols/runes/2026-10-20T00:00:00Z

Fungible tokens whose messages, runestones, ride an OP_RETURN output. BTI decodes them itself; ord is only its audit oracle.

https://blockspace.wiki/protocols/pipe/2026-10-20T00:00:00Z

A September-2023 OP_RETURN token protocol, the Runes precursor, with art in tapscript; no indexer has ever existed, so BTI's replay is the record.

https://blockspace.wiki/protocols/ordinal-sats/2026-10-20T00:00:00Z

The sat family: inscribed sats, bitmaps, sat names and CAT-21 sats. How ord binds files to sats, how BTI books them, and the family's live share.

https://blockspace.wiki/protocols/open-assets/2026-10-20T00:00:00Z

An asset protocol of coloured outputs that BTI decodes itself with a coloured-UTXO walk; B/A 0.72 in the July 2026 measurement run.

https://blockspace.wiki/protocols/op20/2026-10-20T00:00:00Z

BRC-20's JSON shape on OP_RETURN plus a required credit address; no indexer has ever existed, so BTI's replay is the record.

https://blockspace.wiki/protocols/omni/2026-10-20T00:00:00Z

The Mastercoin-lineage ledger, TetherUS included. BTI decodes Class C messages in OP_RETURN itself; a ledger token's bytes are its operations.

https://blockspace.wiki/protocols/mezcal/2026-10-20T00:00:00Z

Runes-lite JSON mezcalstones in OP_RETURN from block 898,750; BTI's decoder transcribes the author's reference indexer, quirks and all.

https://blockspace.wiki/protocols/epobc/2026-10-20T00:00:00Z

Colours written into the nSequence field every input already has: zero carrier bytes, the limiting case of the free-ride index.

https://blockspace.wiki/protocols/counterparty/2026-10-20T00:00:00Z

XCP assets, the first blockspace tokens (2014), with Stamps and Counters as subsets: one asset, one claim, however many sources sight it.

https://blockspace.wiki/protocols/colu/2026-10-20T00:00:00Z

Colored Coins 2.0: a coloured-UTXO protocol over two carriers, OP_RETURN and bare multisig, whose identity is a pure function of chain data.

https://blockspace.wiki/protocols/coinspark/2026-10-20T00:00:00Z

A coloured-output asset protocol whose default route moves units with no CoinSpark bytes at all: the most extreme free-ride measurement recorded.

https://blockspace.wiki/protocols/charms/2026-10-20T00:00:00Z

A zero-knowledge token protocol whose spells state the resulting charms in the clear; it moved from witness to OP_RETURN, and its Bitcoin-side supply is a lower bound.

https://blockspace.wiki/protocols/brc-20/2026-10-20T00:00:00Z

Tick ledgers written as JSON inscriptions, and since 2026-08-11 also on bare OP_RETURN. A BRC-20 mint has two claimants, the sat and the tick. BRC-100 is covered here too.

https://blockspace.wiki/protocols/brc-100/2026-10-20T00:00:00Z

An inscription-borne tick ledger with a two-step transfer; its only mirror died, so BTI was ruled its indexer on 2026-08-11.

https://blockspace.wiki/protocols/bitmap/2026-10-20T00:00:00Z

Bitmap districts are labels on inscribed sats: BTI's opi-bitmap adapter adds a source under Ordinal Sats, never a family of its own.

https://blockspace.wiki/protocols/arc-20-and-atomicals/2026-10-20T00:00:00Z

Atomicals' fungible ARC-20 tickers, whose units ride sats, and its NFTs (containers and dmitems). One definitional indexer, one quarantine, one named gap: realms.

https://blockspace.wiki/protocols/alkanes/2026-10-20T00:00:00Z

Contract tokens called through protostones inside a runestone. metashrew's trace is the record; every contract that ran claims the bytes.

https://blockspace.wiki/protocols/2026-10-20T00:00:00Z

One page per token family BTI measures: how it writes to Bitcoin, how its bytes are attributed, and its live share.

https://blockspace.wiki/projects/spaceblocks.art/2026-10-20T00:00:00Z

Space Blocks: one image that fills a 1 MB block, inscription #83,851,681, 1,047,584 bytes.
