AI Agent Bitcoin Block Explorer and Block Paint: the Bitcoin side and the real people

Ten lifelike people, 350 things to wear, 30 emotes, and a way of standing, looking and moving that never plays the same twice. This is what the update does, how it works, and how to use it.

What it is

AI Agent Bitcoin Block Explorer is a 3D Bitcoin block explorer you walk through, with a common room where a crew can meet. Block Paint is its spray-paint city. Both follow the Bitcoin blockchain live, and the part called The Bitcoin side shows how to use that, step by step. Until now everyone in both was a blocky figure. This update replaces them with real-looking people: the same ten in both games, wearing the same clothes, doing the same moves.

• Ten people, five men and five women, with five skin tones to choose from.
• A wardrobe of 350 pieces in seven sections, each with colours and patterns.
• 30 emotes and dances with matching faces.
• Townsfolk in Block Paint are real people too: skaters, ball players, a busker, a gardener, people on benches.
• Natural movement: each of the ten stands, breathes, looks about and reacts in their own way, and they notice you.

Getting started

AI Agent Bitcoin Block Explorer

1. Open the "play together" page.
2. Type a name and pick one of the ten. Pick an outfit and a skin tone.
3. Scroll to Wardrobe and choose what to wear. Your portrait redraws as you pick.
4. Start a crew, open a hall, or join one with a code. You can also explore alone.

Block Paint

1. Open Block Paint, or walk through the warehouse door in AI Agent Bitcoin Block Explorer.
2. Tap the person button at the top to open Your painter.
3. Pick one of the ten, colours, a skin tone and your wardrobe. Press V (or pinch on a phone) to see yourself.

Your choice is remembered on your device. Other players see it.

The Bitcoin side: how to use it

AI Agent Bitcoin Block Explorer is a Bitcoin block explorer you can walk through. What you see comes from the Bitcoin blockchain, live: blocks, fees and the next block from mempool.space, ordinal tags from ordpool.space, and inscriptions from ordinals.com. Every picture in this part was taken on the live portal on 12 November 2026, with real blocks.

1. The newest block, and the one being made

Open AI Agent Bitcoin Block Explorer and you start on the next block: the block being put together right now from transactions waiting to be mined.

• The tiles along the top are the chain. On the left are the blocks still waiting (+3, +2, +1 and NEXT). On the right are blocks already mined, newest first. Each tile shows its fees, size and number of transactions. Click a tile to open that block.
• LIVE (at the bottom) takes you back to the next block. ‹ and › beside it step one block back or forward.
• Fee weather is the band under the tiles: the middle fee of each of the last 144 blocks (about a day). 1D, 1W, 1M and 3M change how far back it goes.
• FEED (top right) shows or hides the live feed: blocks as they are found and who found them, big moves, and transactions joining the next block.

2. Read a block: fees or ordinals

Every little box in the cube is one transaction.

• The button at the bottom names the view you are in. FEES colours each box by the fee it paid; the colour key is under the block number. Click it to switch to ORDINALS, which shows what the block carries: inscriptions, BRC-20 and other tokens, runes and more.
• The eye button is X-ray: it lets you see inside the cube.
• Parcel types (bottom left): hover over a type to light it up, click it to keep it lit. The tabs switch between inscriptions, tokens and transactions.
• Click a box to open its card: its place in the block, fee rate, fee, size, the total it sends, any ordinals and its ID. With a type kept, ‹ and › on the card step through every parcel of that type.

3. Walk into the block

Press the round button at the top left (walk into the block). Inside, the block is a hall of shelves. Each transaction is a parcel on a shelf, sorted by kind, with a sign giving the count. Pictures show on their parcels and tokens show their names. The door at the far end leads to the next block.

• Computer: click to look around, W A S D to walk, Shift to run, click a parcel to hold it, Esc to let go.
• Phone: pad to walk, drag to look, tap a parcel to hold it.

When you hold a parcel, its card shows what is inside it: the picture, the text, or a token's details, with the transaction under it. Then you can:

• VIEW BIG (V): see it large on a big tablet, with FULL SCREEN and OPEN buttons. CLOSE goes back.
• SHOW IN COMMON ROOM (C): put it on show in the common room (see part 5).
• FOLLOW IT BACK (F): a gold line leads from the parcel to where the inscription was made and each place it has moved. The bar at the top names each step (MADE, a move, or PAID TO A MINER); ◀ and ▶ step along it and × ends it.

4. Search and fast travel: the tablet

Inside, press T (on a phone, tap the tablet button) to open the tablet.

• Fast travel: COMMON ROOM, NEWEST BLOCK or GENESIS BLOCK.
• Search: type, press FIND, then GO. Its help line lists what it can find: a block (840000 or 840000.bitmap), a parcel (12.840000.bitmap), an inscription (#1000 or its ID), a transaction ID, an address, or a name (satoshi.sats).
• After GO, an arrow shows the way, with the distance. CLEAR ARROW takes it away.

5. The common room's live screens

The big screen in the Forum (the sunken floor in the Grand Hall) shows the chain as it happens. Walk up and click it, or press E, to see it up close; FULL SCREEN fills your screen with it. It shows:

• Waiting to be mined: the next three blocks as they stand, with their fees.
• Just mined: the last four blocks, how long ago, and which pool found them.
• Next halving: the block it happens at and how many blocks to go.
• Next block · usual wait: the average time between blocks over the last day, and the time 9 in 10 blocks came within.
• Best time to get in: the lowest fee getting into the next block now, set against the last 144 blocks. NOW IS CHEAP, FAIR or DEAR says how it compares.
• Low fee · scored on today: fees to pay, each tested on the last day's blocks: cheap gets in within about 3 hours, patient within about 1 hour, and next block in the next one. The numbers say how often each would have worked.
• Block weather: the fee for the next block over the last day, and whether it is busier or quieter than usual now.

On show: a parcel you put on show floats large over the middle of the Forum. One is on show at a time. In a crew everyone sees the same one, and it is kept on your device for next time. The button at the top takes you back to the block it came from.

The rare sats board in The Mempool, the neon bar, lists kinds of rare sats, how many of each exist, and a price for one sat. The prices come from ordiscan.com, with the day they were read at the bottom. It moves on to the next kinds every few seconds.

6. Block Paint's Bitcoin side

Block Paint City follows the chain too. On the portal it reads the newest block from mempool.space, with backup sites if that is down.

• Block screens on the rooftop and in the subway show BITCOIN BLOCK, the newest block's number, and a GMT clock that runs on from that block's time stamp.
• The subway departures board lists the Downtown & Sats Bay train, the Block train ("with the next block") and the last block.
• When a new block is found the place you are in reacts: in the subway the next train in is an orange block train, in the train yard an orange train runs through, and on the rooftop fireworks go up.
• The skate park scoreboard counts down the blocks to the next halving.
• Paint apps: the Paint menu has "Look for paint apps". On the portal it says paint apps are found once the game is inscribed. Until then, "Try a paint app file…" loads one from your device.

The ten

Each person has a name, a body, and a way of carrying themselves. The ways are small, but they are why a room of them does not look like copies of one figure.

LeoEasy-going

A slight slouch, settles from foot to foot, folds his arms when left standing.

KofiSure of himself

Upright, slow to blink, holds your eye.

RenCurious

Eyes always going somewhere, quick to nod.

MarcoComposed

Stands still longest, checks his watch.

SamRestless

Shifts his weight often, big hands when he talks.

MiaWarm

Head a little to one side, quick to smile.

ZaraPoised

Tall posture, steady gaze, few movements.

YukiShy

Looks away more than she looks at you, small gestures.

ElenaMeasured

Upright, hand to her chin when thinking.

NiaLively

Always on the move, quick to smile, talks with both hands.

The wardrobe

Seven sections, fifty pieces in each. Every piece can take a colour, a second colour and a pattern (hoops, stripes, checks, plaid, dots, camo, tie-dye, zigzag, pinstripe).

Every piece fits all ten bodies, because each one is built from the person's own shape. The pieces also know about each other:

• Close tops tuck into high waists; loose ones hang over.
• Trouser legs go into boots or over them, depending on which has room.
• Sleeves go into long gloves or over them the same way.
• Hair is pressed in under a hat.
• Skin under clothes is not drawn, so nothing pokes through.

The other six sections are below. Open one to see all fifty of its pieces; tap a picture to see it full size.

Trousers all fifty

Shorts all fifty

Skirts and dresses all fifty

Shoes all fifty

Hats all fifty

Gloves all fifty

Emotes and dances

There are thirty, in four groups, and every one is pictured below. In AI Agent Bitcoin Block Explorer, with a crew, press Q or the smiley button to open the emotes. Tab changes group and 1 to 9 picks one. Each has its own face to go with it. A dance keeps going until you walk off.

How they move

The aim was simple to say and hard to do: nothing a person does on their own should look like a loop.

Standing

Nobody stands frozen. Each person settles from one foot to the other at uneven times and by different amounts. Posture changes a little now and then. Breathing has its own pace that wanders, with a deeper breath once in a while, and the shoulders rise with it.

Eyes and faces

Blinks come at each person's own pace and never on a beat, sometimes twice together. Eyes often blink as they move, and they reach a thing before the head does. The resting face is not fixed: a small smile comes and goes, brows lift, a little more on one side than the other.

Noticing each other, and you

• When someone comes near, people look at them, with a smile or a lift of the brows.
• That includes you. Walk up to someone and they look at you.
• They hold your eye for a while, look away, and come back. How long depends on who they are.
• When someone talks, the people near them nod now and then, and after a moment turn their body to face the speaker.
• Stand too close and they lean back a little.
• Someone busy with a phone, a guitar or a spray can keeps their eyes on what they are doing.

Talking with the hands

When a person talks, one hand or both come up in front and move as the words go. Which hand, how high and how wide changes every second or two.

Left standing

After a while a person finds something to do: fold their arms, check a watch, put a hand to their chin, or just change stance. Each has their own favourites and never does the same thing twice running.

Walking

Walking leans into the step, more at a run. Arms swing by different amounts for different people, and one arm a little more than the other.

Feet, shoes and skirts

Soles stay on the ground: the lowest point of each shoe is kept at floor height, whatever the shoe. A standing foot lies flat, and when the heel lifts the foot bends at the ball. Sitting, a shoe that would be in the floor is lifted by the knee coming up a little.

Full skirts hang from the hips, so a raised leg pushes a skirt out instead of carrying it up. Sitting, a skirt lies over the lap.

Where you meet them

The common room in AI Agent Bitcoin Block Explorer

Your crew meets here. People sit properly on what is there: the sofa by the fire, a bench in the garden, the steps of the Forum, a stool at the bar. They hold things the way a hand does: a pint glass, a parcel shown as a tablet.

Block Paint City

Six places: the rooftop, the skate park, the subway, the alley, the warehouse and the train yard. Three of them have townsfolk, who are the same ten in everyday outfits:

• Rooftop: a gardener tending the plants, and someone on a bench.
• Skate park: skaters, ball players, and people sitting.
• Subway: a busker with a guitar, and people waiting with their phones.

How it works

Everything is drawn by a small engine written for these games. It uses the browser's own 3D (WebGL2) and no outside game library.

• One body, ten people. All ten share one base body. Each person is a set of changes to it, so a piece of clothing made once fits everyone.
• Clothes follow the body. Every point of a garment is tied to a few points of the body underneath, plus a small distance out. Change the body and the clothes change with it.
• Fabric without pictures. Wardrobe pieces are coloured by a small program on the graphics card: cotton, denim, knit, fleece, leather, satin, metal and nylon, with stitching, seams and patterns. That is why 350 pieces come to about 20 MB instead of hundreds.
• Moves in layers. A person's pose starts from standing or walking. On top go sitting, holding things, an emote, then the natural layer described above, then rules that keep feet on the floor and hands where they should be.
• Chance with a character. Every timing in the natural layer is drawn by chance, shaped by who the person is. Slow wandering values are made from three waves whose lengths share no beat, so they never come round again.
• Only what you need. A player downloads the files for the people and clothes actually in view, not the whole wardrobe.
• Loading. Nobody is drawn half-arrived. In Block Paint a place stays covered until its people are ready. A name tag never shows before the person does.

Resources

• Bodies, skins, hair, eyes and the ready-made outfits: MakeHuman assets released as CC0 (free for any use).
• Walking and standing: the Carnegie Mellon University motion capture database. The data used in this project was obtained from mocap.cs.cmu.edu. The database was created with funding from NSF EIA-0196217.
• Wardrobe pieces, emotes, dances and the natural movement: made for this project.
• Bitcoin data: mempool.space (blocks, fees, the next block), ordpool.space (ordinal tags), ordinals.com (inscriptions) and ordiscan.com (rare sat prices).
• Where it lives: the Ordinal Portal on GitHub Pages. The pages are block-cube.html, block-cube-together.html and block-paint.html, with the people's files in a people folder beside them.

Limits to know

• Emotes are in AI Agent Bitcoin Block Explorer, not yet in Block Paint.
• In Block Paint up to 32 townsfolk are drawn at once (12 on a phone), nearest first, within 80 metres. No place has that many today.
• A device that cannot run the people at all still shows the old figures, so players there see somebody.
• In AI Agent Bitcoin Block Explorer, crewmates connect after you arrive, so they appear a moment later.
• The games set how fast people walk, so walking speed itself does not vary.
• A seated full skirt is simple: it sits like a short tube round the thighs.
• There is no squinting in bright light, and hair does not move on its own yet.
• The two main pages are each larger than a single 360 KB inscription.

Update log

• 12 November 2026Block Cube is now called AI Agent Bitcoin Block Explorer. Pictures taken before then still show the old name.
• 12 November 2026The blog now covers the Bitcoin side of AI Agent Bitcoin Block Explorer and Block Paint, as a how-to with pictures taken on the live portal. Two pictures that showed test block numbers (the seats and the Your painter panel) are replaced with pictures from the live portal.
• 12 November 2026The blog gains moving pictures, a picture of every emote and a picture of every wardrobe section. The play together page and Block Paint's help card now link here. Four sharp dance moves (in the Robot, the Woah, B-T-C and Mind blown) used to jump in a single frame; they now take about a tenth of a second. Elbows no longer pinch thin when an arm is raised high or a thumb is turned down: the turn is shared between shoulder, forearm and wrist, as in a real arm.
• 12 November 2026This blog goes up, with a Blog button on the portal's AI Agent Bitcoin Block Explorer card.
• 11 to 12 November 2026Natural movement: shifting weight, breathing, each person's own blink, noticing each other and you, nodding along, talking with the hands, skirts that hang and sit.
• 11 November 2026Shoes and feet rest flat on the ground. The old block figures no longer show while people load, and Block Paint waits behind a short loading cover.
• 11 November 2026The real people go live in AI Agent Bitcoin Block Explorer and Block Paint: ten people, 350 wardrobe pieces, 30 emotes and dances.
