Answers #

How many Degents are there? #

The Degent Club collection is 10,000 when fully minted: 4,112 inscribed (as of 2026-09-25 23:24:51 UTC). Each Degent is an inscription of a Pepe in a tuxedo. Older pages have shown other counts: the site's rebuild specification records 4,027 minted on the old site and 4,113 in an internal analysis, against the collection list's 4,112.

How much of Bitcoin's blockspace do tokens use? #

In Book A, the widest of BTI's books, tokens are attributed 133.75 GB, which is 17.21 % of the 777.04 GB of chain bytes the books cover (as of block 972,299, 2026-10-20 09:30:48 UTC). The narrowest, Book C, file and message bodies alone, holds 4.68 %. In the July 2026 measurement run, data payload peaked at 45.4% of block bytes, at height 833,000.

What are Book A, B and C? #

They are BTI's three answers to how many bytes back a token. Book C, the content book, counts the artifact bytes alone. Book B, the regional book, adds the structure the token's operations wrote, read or moved through. Book A, the inclusive book, counts whole transactions bought for the token, shared where shared. On every entry, C ≤ B ≤ A.

What are spent sats? #

Here, spent sats means the sat ranges of outputs that have already been spent. blockspace.to, a Blockspace Labs product, runs a fork of ord with --index-spent-sats, so a spent output still answers with its sat ranges; an ord without that flag cannot. BTI's August 2026 handoff notes name CAT-21 as the only normal-operation consumer of those ranges.

What does "as of block H" mean? #

Every block.space figure is bounded by a block height. "as of block H" names the one block, H, that figures are synchronised to; where a ranking or the books sit at another height, pages name those too. A number without its height is not shown. The books stand at block 972,299 and the chain tip at 972,304 (as of block 972,301, 2026-10-20 09:35:17 UTC).

What does "not measured" mean? #

The instrument has no figure for that thing: a book not measured for a protocol, a sat the record has not bound to an inscription, a holder the appendix cannot see. block.space writes these in words, never as 0. A zero is a measured zero, such as a protocol with no artifact body measuring zero in Book C.

What is a rune? #

A rune is a fungible token whose operations are written in an OP_RETURN output called a runestone. Runes began at block 840,000, in April 2024. BTI decodes them natively, with ord only as an audit oracle, and identifies each rune by its etching's block and transaction. UNCOMMON•GOODS is rune #0. blockspace.to's ord counts 216,409 runes (as of block 972,304, 2026-10-20 10:17:29 UTC).

What is a sub-1 sat/vB transaction? #

It is a transaction paying less than 1 sat per vbyte, the default relay floor of Bitcoin Core. Blockspace Labs' node runs stock Bitcoin Core with a minrelaytxfee of 0 sat/vB (as of block 972,304, 2026-10-20 10:17:29 UTC), so it relays and keeps such transactions. This sub-1 sat/vB relay is a Live Labs project, and its mempool explorer is explore.block.space.

What is an inscription? #

An inscription is a file that ord binds to a sat, carried in a witness envelope. To BTI it is not a token: the inscription is content, and the sat it is bound to is the token that claims the bytes. Its size on block.space is its Book C figure, the file alone. blockspace.to's ord counts 128,169,401 (as of block 972,304, 2026-10-20 10:17:29 UTC).

What is Blockspace Holdings? #

Blockspace Holdings is the holding company behind block.space and the projects listed at block.space/projects. Its own site, blockspace.holdings, says: "We acquire & Hodl Blockspace Assets. We serve public Blockspace Infrastructure." As of 2026-10-20 it has 18 properties, from the meter and Blockspace Labs to Scribbit, degent.club and bitmap.holdings.

What is Blockspace Value Theory? #

Blockspace Value Theory (version 3.0, July 2026) is a living document and an untested thesis. It proposes that tokens linked to files committed on Bitcoin, such as runes, BRC-20s and inscribed sats, form one commodity market denominated in kilobytes, with a price floor proportional to the kilobytes consumed. Its central open question is whether markets price kilobytes or fees.

What is blockspace? #

In the block.space documents, blockspace is the capacity of Bitcoin's blocks, consumed by transactions. Blockspace Value Theory calls it "a socially constructed commodity built on top of a protocol-enforced constraint" and argues it exists only while a block is being built. BTI measures what was consumed: every byte of every transaction, counted exactly, from the genesis block forward.

What is BTI? #

BTI, the Blockspace Token Indexer, is the instrument behind every block.space number. It walks every Bitcoin transaction from the genesis block and counts every byte exactly; nothing is sampled or estimated. It reads each token protocol's operations under that protocol's own rules, then writes the three books, the judged attribution of blockspace to every token.

What is BTP? #

BTP, the Blockspace Token Protocol, is a draft, version 0.1 of 2026-07-29, describing a protocol that does not exist. The draft describes an attribution-layer protocol: where other metaprotocols answer who owns which token, BTP would answer which token owns which consumed bytes, and make that ownership transactable. Its first operation, MINT, would issue BYTES against a transaction's bytes.

What is BYTES? #

BYTES is a draft, version 0.2 of 2026-07-29, describing a token that does not exist. The draft describes a fungible token minted by attributing a transaction's consumed blockspace to it, one token per byte, so 1 BYTES equals 1 byte. Its stated aim is to make the price of a consumed kilobyte directly observable: the BYTES price times 1,000.

What is carriage? #

Carriage is the bytes of a transaction a token merely rode: a payment or consolidation that would have happened anyway and carried the token along. BTI measures carriage in full but never counts it as backing. Carriage answers what moved through the blockspace; backing answers what it was bought for.

What is Scribbit? #

Scribbit, at scribb.it, is a planned Blockspace Holdings product, listed as coming soon. Its line is "Write it once. Keep it forever." The owner's design brief, not yet confirmed, describes a non-custodial way to write up to about 400 KB onto Bitcoin, for contracts, records and attestations, paying only the network fee. No app exists yet.

What is the Shared Claim Axiom? #

The Shared Claim Axiom is a proposed refinement of Blockspace Value Theory: when several tokens claim the same consumed bytes, the kilobytes are shared equally, bytes consumed divided by n, where n counts the distinct assets claiming them. The axiom's own text calls "shared equally" a rule of thumb, not a derived result.

What is the witness discount? #

The witness discount is SegWit's rule: a non-witness byte weighs 4 weight units and a witness byte 1, so at f sat/vB a witness byte costs f/4 sats. In the July 2026 measurement run, inscriptions measured 3.374 bytes per vbyte and runestones 1.0000. BVT proposes the discount sells the same resource at a quarter of the price.

Where can I get the data? #

block.space serves its figures as JSON under /api/, readable from any origin: /api/summary for the books' totals, /api/protocols per protocol, /api/frontier for the cursors, and each board's endpoint, such as /api/leaderboard. The boards return their heights and unrounded values. This wiki also publishes llms.txt, llms-full.txt and blockspace.json, with every page's sources.

Why does block.space count bytes and not vbytes? #

BTI's design rule R5 says raw bytes are the measure and vbytes an observable. Blockspace Value Theory argues that every byte, witness or not, is downloaded, validated, propagated and stored by nodes, so weight discounting confuses price with quantity. BTI still carries both everywhere, because the ratio of bytes to vbytes is the witness discount itself.

block.space #

What does block.space measure? #

How much of Bitcoin's blockspace is attributed to tokens, token by token, byte by byte. BTI counts every byte, catalogues each protocol's operations, and writes three books per token: Book A, Book B and Book C.

Why are there three books? #

They answer three different questions about the same token: how much blockspace was consumed by transactions that touched it, how much was consumed for it, and how much of that is substance. No single number answers all three. On every entry C ≤ B ≤ A.

Why does every figure name a block height? #

Every figure is bounded by the height the books are written to, and every ranking carries as of block H. A number without its height is not shown, and a block counted but not yet in the books says so rather than showing zeros.

Does a zero on block.space mean nothing was there? #

A zero is a measured zero. Anything the instrument has not measured is written as not measured, never as 0.

Is the code public? #

The code of the sibling explorer, explore.block.space, is public at BLOCKdotSPACE/blockspace-explorer. It is the only one of block.space's two repositories that is public (as of 2026-10-20).

degent.club #

How many Degents are there? #

The collection is 10,000 when fully minted. Today there are 4,112 inscribed (as of 2026-09-25 23:24:51 UTC). The 10,000 is the size of the finished collection, not a count of Degents that exist.

What does a Degent have to look like? #

The club's minting rules ask for a square JPEG of at least 200KB, a Pepe character in a tuxedo with a mandatory bowtie, and the frame with a placard saying "DEGEN", "DEGENT" or "REGEN". You may mint as many as you want.

Why have older pages shown other counts? #

A review of the site found three conflicting counts: the old site's 4,027 minted and 1,470 MB, 4,112 in the collection list, and 4,113 and 1,508 MB in an earlier analysis. It also calls the old "10K = 3+ GB" a projection presented as fact.

Can I use the Degent art or name in my own project? #

No. The code is Apache-2.0 and the docs CC BY 4.0, but the artwork, the comic, the collection's images, the names and the frame and placard are not licensed. A fork must use its own name and art. Using the names to refer to the project is fine.

Who decides changes to the code? #

Each component's owning team reviews and merges by pull request, under lazy consensus. Significant decisions need an Architecture Decision Record. Licensing, trademarks and the Code of Conduct are decided by Blockspace Holdings.

scribb.it #

Can I use Scribbit today? #

No. The app is coming soon (as of 2026-10-20) and no Scribbit code exists. The scribb.it site describes the planned product only: it connects no wallet, takes no payment and sends no transaction.

Will Scribbit hold my money? #

As planned, Scribbit is non-custodial: your own wallet funds and signs the transactions. This is not yet a confirmed commitment (as of 2026-10-20).

What will it cost? #

As planned, the network fee only, with zero platform fee (not yet confirmed, as of 2026-10-20). For scale, a real 387,641-byte PDF paid 49,842 sats for its whole reveal transaction in block 965,177.

Why about 400 KB? #

Bitcoin Core relays a transaction only up to 400,000 weight units, and a witness byte weighs one unit. So a standard reveal can carry a little under 400,000 bytes of payload.

Can I delete or change what I write? #

No. Once a reveal is mined, nobody can edit or delete its bytes. To correct a record, the site suggests writing a new one that refers to the old one by its inscription id.

counters.fun #

Why are some counters missing from counters.fun? #

Its one rule is that only counters whose file is on Bitcoin are displayed. A pointer counter is a valid counter, but showing it would mean fetching bytes from someone else's server, so counters.fun does not render or trade it.

Which wallets work with it? #

Both Counterparty browser wallets, XCP Wallet and Horizon Wallet, through one adapter. Every flow is signed as a PSBT, because Horizon cannot sign a raw transaction; when a wallet cannot broadcast, the app falls back to Esplora.

What is price per KB? #

Price per KB is the market cap spread over the bytes the asset carries on chain: price × circulating supply ÷ KB, in the price's own unit. It is shown on every pooled card, dispenser card and DEX row.

Can I buy from a dispenser by sending it BTC? #

No. Since block 866,000 a bare BTC payment to a dispenser buys nothing. counters.fun's buy composes a Counterparty dispense, shows the price plus the miner fee, and the wallet signs it.

What can I mint there? #

Three things through one commit and reveal path: a new counter, a reinscription on an asset you own, or a fairminter deploy whose description is the file. The XCP-69 preset follows xcp.fun's template and opens a liquidity pool at soft cap.

counters.gallery #

What is a counter? #

A counter is a file committed to Bitcoin as the description of a Counterparty asset, carried in witness data by a Counterparty taproot envelope, and numbered gap-free in order of creation from #0.

Why do counters start at block 902,000? #

That is where Counterparty's taproot encoding activated. Before it, an asset description could not reach the chain in witness data, so no counter could exist. Counter #0, XDUALS, came five blocks later, at 902,005.

Does the explorer show files hosted somewhere else? #

No. A counters server only shows on-chain files. A pointer counter is shown as its pointer text and never fetched, and HTML and SVG run sandboxed.

Can a counter's number change? #

Numbers are append-only, but numbers near the tip are provisional until confirmations pass, because a reorg rolls back and re-numbers identically. Amendment A1 (2026-09-24) removed one derived event, #163, and every later counter moved down by one.

How can two explorers be sure they agree? #

Each counter extends a rolling hash. Two indexers agree on the whole history if and only if their latest rolling hash matches.

devcash.dev #

What is Devcash? #

In its own words, "Devcash (DEV) is cash for the developer economy. It is the official currency of Blockchain Developers United." It offers a bounty platform and a decentralized exchange. See Devcash.

How does the bounty platform work? #

Users post a task and crowdsource developer talent, or hunt bounties: they perform developer tasks and earn DEV. A bounty can carry an ETH or a DEV reward.

Where is it hosted? #

On its own server, separately from Blockspace Holdings' other projects (as of 2026-10-20).

Is it on blockspace.holdings? #

No. Blockspace Holdings chose on 2026-10-20 to leave it off blockspace.holdings. It stays on block.space/projects.

mintbitbars.xyz #

What is a bitbar? #

A bitbar is a bar-shaped inscription whose size is its name. The 1kB bitbar is exactly 1,024 bytes.

Can I mint a bitbar there today? #

The page answers, but on 2026-10-19 the server behind its Mint button's QR code did not answer, and only the page and image are served. No source says whether payments are being turned into mints.

How was a mint meant to work? #

The page asks you to use an ordinals wallet (it recommends Unisat), send 0.00002 BTC to the address it shows, and wait: the bitbar is minted to the sending address, at a standard fee rate of 3 sats/vB.

Where is its code? #

In the public repository antron3000/Bitbar-Minting-App: the page, a payment-watching server and a minter script.

blockspace.holdings #

What is blockspace.holdings? #

The page of Blockspace Holdings, the company behind block.space and the other projects. It shows every project as a holding, with block.space, degent.club and scribb.it featured.

Why does it say "Hodl"? #

The spelling is deliberate, and it stays. See Hodl.

Where do the cards come from? #

From the same project list that block.space/projects shows. The cards are generated from that list, not kept by hand. Each line comes from the project's own site or its own source.

Why is devcash.dev not on the page? #

Blockspace Holdings chose on 2026-10-20 to leave it off blockspace.holdings. It stays on block.space/projects.

spaceblocks.art #

What is Space Blocks? #

Space Blocks is inscription #83,851,681: one JPEG, 1537 × 1537, of 1,047,584 bytes, inscribed in block 881,188.

Does it really fill a block? #

It fills 1,047,584 of the 1,048,576 bytes of a 1 MB block, 99.9 %.

What are the other works on the site? #

The page "Other works that fill a block" lists the inscriptions block.space classes as whole-block, content over 3,500,000 bytes: 110 of them as of block 972,262, largest first, each linking to its record on block.space.

Who made it? #

No source names an artist or gives a story (as of 2026-10-20), so the site shows only the facts.

blockspace.wiki #

What is blockspace.wiki? #

This site. In Blockspace Holdings' words, "a place to write all information and documentation about blockspace": a page per project with its glossary and FAQ, the concepts, the protocols, and the data.

Where do its facts come from? #

Only from Blockspace Holdings' own documents and the live data of its own Bitcoin node and indexers. Every page lists its sources, a claim with no source is not written, and every live figure carries its "as of".

Is the theory presented as fact? #

No. Blockspace Value Theory is a living document and an untested thesis; BTP and BYTES are drafts describing things that do not exist. Theory pages say so.

Can agents read it? #

Yes. It publishes machine surfaces: a sitemap, robots.txt that welcomes crawlers, llms.txt and llms-full.txt (the whole wiki as Markdown), JSON-LD, an Atom feed and /.well-known/blockspace.json.

litepedia.space #

What is Litepedia? #

Litepedia is a Blockspace Holdings project to upload Wikipedia to Litecoin and let people pay LTC (Litecoin's coin) to make edits, with a robust editing system.

Can I read or edit it yet? #

No. As of 2026-10-20 litepedia.space shows a Coming soon page. Nothing has been uploaded to Litecoin.

What does it need before it can start? #

A Litecoin node and an inscription indexer for Litecoin, to put content on-chain. Blockspace Holdings runs no Litecoin node as of 2026-10-20.

blockspace.loans #

Does blockspace.loans offer loans? #

No. Nothing is built (as of 2026-10-20). The concept under consideration is an information page only, with no lending service and no offer of credit, and it is not confirmed.

What does the domain show now? #

A generated "Coming soon" page, written from the domain's row in the project list.

blockspace.markets #

Can I buy on blockspace.markets? #

No. The page only shows listings. Buying happens at block.space/buy, the one place with the wallet flow, which the page links to.

How is the price per kilobyte worked out? #

The venue's asking price, divided by the blockspace block.space's books attribute to the asset under Book A, as the buy board computes it. See sats per kB.

How fresh is it? #

The page is rebuilt every 10 minutes and every section says the time it is as of. If the board returns nothing, the last page stays, with its own as-of time.

blockspace.news #

Where do the numbers come from? #

Every figure is read from block.space's public API and bounded by the height its books are written to. The site says nothing is estimated, and it makes no prose claims beyond the data.

When does a new edition appear? #

Once a day. A snapshot is taken at 00:15 UTC, and the edition is the difference between that day's snapshot and the one before.

What happens if the books are rewound? #

A rewound or rewritten set of books is reported as "no comparison", never as a negative.

Is there a feed? #

Yes. Each edition has its own page by date, the archive lists them all, and an Atom feed is at /feed.xml.

blockspacelabs.com #

What is Blockspace Labs? #

The research and development arm of Blockspace Holdings, at blockspacelabs.com. Its site lists research projects as cards, each marked Live or Research, with figures measured on Blockspace Holdings' own Bitcoin node and indexers.

Does the Labs node really relay transactions below 1 sat/vB? #

Yes. It runs stock Bitcoin Core with a minimum relay fee of 0 sat/vB (as of block 972,304, 2026-10-20 10:17:29 UTC), so it relays and keeps them. See sub-1 sat/vB relay.

Does it relay 4 MB transactions? #

No. Stock Bitcoin Core treats a transaction over 400,000 weight units (100 kvB) as non-standard, so 4 MB relay needs a patched node. In Blockspace Holdings' words it is "just a research project".

Are the research projects producing results? #

Not yet, as of 2026-10-20. In Blockspace Holdings' words, the Labs projects stay "descriptive research projects for now". The cards say what each study is and what data it uses; nothing is built behind them.

How is blockspace.to related to Labs? #

blockspace.to is a Blockspace Labs product: an ord explorer and indexer that also tracks spent sats.

blockspace.to #

What does blockspace.to do? #

It is an ord explorer and indexer that also tracks which sats have been spent. In its own line: "Tracks spent sats. A Blockspace Labs product." See spent sats.

How many inscriptions does it index? #

128,169,401 inscriptions, as of block 972,304, 2026-10-20 10:17:29 UTC: 127,697,358 blessed and 472,043 cursed.

What are lost sats? #

Sats that coinbase transactions never claimed, so they exist in no output. ord counts 2,895,844,904 of them (as of block 972,304, 2026-10-20 10:17:29 UTC). See lost sats.

Who runs it? #

Blockspace Labs, the research and development arm of Blockspace Holdings. It runs on Blockspace Holdings' own Bitcoin node and indexers, and block.space's inscription content depends on it.

blockspace.space #

What will blockspace.space be? #

Not decided, as of 2026-10-20. The concept under consideration is a view of where the space in Bitcoin's blocks goes. It is not confirmed, and the domain keeps its landing page until then.

What does the domain show now? #

A generated "Coming soon" page, written from the domain's row in the project list.

bitmap.holdings #

What is a Bitmap? #

In bitmap.holdings' own words, "Bitmaps turn each Bitcoin block into a piece of digital land." Each block becomes a coordinate, each coordinate becomes ownable, and each ownership becomes programmable. See Bitmap.

Is bitmap.holdings part of Blockspace Holdings? #

Yes. It is one of Blockspace Holdings' properties, hosted separately from the other projects. Blockspace Holdings counts it among its holdings (as of 2026-10-20).

Is it the bitmap that BTI catalogues? #

No source links the two. BTI's token catalogue has a "bitmap sats" entry, read by its opi-bitmap adapter, where the inscription is a district claim and the district number is a label on the sat. This wiki makes no claim about what bitmap.holdings holds.

How do I get in touch? #

Its site has a contact form and a "Tweet us" link. It asks to hear from people working on Ordinals or Bitmaps, on-chain identity, metaverse or game integrations, or Bitcoin infrastructure.
