Let me begin off by acknowledging that Ordinals are superb! Ordinal Idea is a really intelligent technique of tokenizing particular person satoshis and Casey Rodarmor deserves excessive reward and recognition for gamifying the blockchain and Making Bitcoin Enjoyable Once more. For the primary time within the historical past of Bitcoin, we have now NFTs on the heaviest proof-of-work chain, preserved indelibly ceaselessly!
Okay, now that we received that out of the way in which, let’s dive into some “inconvenient” historical past. Ordinals was not the primary — removed from it. Tokens have existed on meta layers on prime of the Bitcoin blockchain for not less than a decade. Most have been flashes within the pan like Coloured Cash; by no means fairly launched, like RGB; or under-the-radar this entire time, like Counterparty.
It’s possible you’ll not have heard of Counterparty — an incredibly excessive variety of Bitcoiners haven’t — which launched in 2014 with a good “proof-of-burn” that despatched 2,130 bitcoin to an irrecoverable burn tackle, however you could have heard of Uncommon Pepe, an early, pioneering “tokenized artwork” assortment on Bitcoin consisting of 1,774 hilarious and dank works revolving round Pepe the Frog. RAREPEPE (Sequence 1, Card 1) generally known as the “Nakamoto Card” bought for upwards of half one million {dollars} throughout peak NFT mania. One other card, HOMERPEPE (Sequence 2, Card 32) was most likely the primary vital NFT sale ever at $38,000 in 2018 after which once more for $320,000 in early 2021.
Oh, did I point out I’m an unique Uncommon Pepe artist? I submitted a bit entitled CHAMPAGNETNT (Sequence 25, Card 38) that poked enjoyable on the then-current ICO increase, and eventual bust. The beauty of the Uncommon Pepe assortment is that it acts as an illustrative time capsule of what was taking place in Bitcoin (and crypto) in the course of the 2016-2018 period, warts and all. However this was all earlier than 2021, earlier than NFTs went bananas, so there actually wasn’t a lot hypothesis or expectation of revenue. It was only a bunch of dudes (principally dudes) hanging out on Telegram and making dank artwork to share with associates. I gave away half the provision of my card with out even stopping to think about if it might be price one thing “sometime”.
Let’s skip ahead a number of years. It’s early 2023 and Ordinals is making waves because the shiny new factor. What makes Ordinals novel? A intelligent technique of FIFO (first in; first out) accounting, which reimagines waves of satoshis as particular person, trackable particles. It’s an abstraction, as a result of satoshis don’t actually exist as particular person, non-fungible items. But when everybody agrees on the FIFO accounting technique, we will all collectively consider that they exist and subsequently they do! The wave-function collapses due to the observer impact of Ordinal Idea. And as soon as they exist, we will additionally fake that proudly owning a sure one corresponds with possession of a selected inscription on the blockchain, very like a star registry provides you a declare on some distant solar. Ordinal Idea is a lens by which to view the blockchain in fascinating new methods. It’s like magic!
So after I first discovered about Ordinal Idea I used to be fully blown away. I at all times thought, “Effectively you possibly can’t simply manifest one thing new into existence just by claiming it to exist utilizing an arbitrary counting technique fully extrinsic to the system itself”. However apparently you possibly can! The bogus partitions in my thoughts that had been constructed up round “loopy concepts that might by no means work” all of a sudden vanished and I might see a transparent path in entrance of me: I could make up stuff too! And that’s how Bitcoin Stamps was born. Effectively, not precisely. Concepts are a dime a dozen, however the implementation of an thought is de facto what brings it to life. I’ve had the privilege of working with some nice coders and engineers which were indispensable in launching and evolving the Bitcoin Stamps protocol: Kevin, Arwyn, Regan, B0B Smith, and lots of others. We had been additionally lucky sufficient to leverage the decade-old Counterparty protocol, maintained by many lean years by stalwarts like JDog and Joe Looney, to rapidly bootstrap Bitcoin Stamps.
So what precisely is a Bitcoin Stamp? Effectively, it’s Safe Tradable Artwork Maintained Completely.
Primarily, a picture file, like a JPEG or GIF, is transformed into a protracted Base64 string — Base64 is a technique to encode binary knowledge as printable textual content — that’s appended to the URI (Uniform Useful resource Identifier) “stamp”: and positioned within the description subject of a Counterparty transaction. Explorers and wallets convert these lengthy Base64 strings again into viewable photos.
Right here is the Base64-encoded string of the very first Bitcoin Stamp (#0):
stamp:iVBORw0KGgoAAAANSUhEUgAAAAUAAAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO9TXL0Y4OHwAAAABJRU5ErkJggg==
An enormous promoting level for Bitcoin Stamps is the preservation of information as soon as minted on the blockchain. How is that this persistence of information achieved? The way in which Counterparty usually operates is to encode knowledge right into a transaction’s OP_RETURN. OP_RETURN’s are restricted to 80 bytes which is sort of restrictive from a “storage” perspective. Nonetheless, OP_RETURN works effectively for conventional NFTs that make use of an HTTPS pointer to a useful resource on a third-party server like AWS. Generally, whenever you inform individuals the artwork isn’t really “on chain” it’s like telling them Santa Claus doesn’t exist. Alas, it’s true: The overwhelming majority of NFTs all through the years are mere tips that could off-chain artwork which makes them very vulnerable to bit-rot. When the AWS invoice stops getting paid, the artwork is gone ceaselessly.
There may be one other means, nonetheless, to encode bigger quantities of information utilizing a normal Counterparty transaction: naked multisig encoding. Primarily, when a transaction’s knowledge exceeds 80 bytes, Counterparty as an alternative chunks and encodes that knowledge right into a naked multisig’s key-strings, utilizing a 1-of-3 quorum the place two of the three keys are utilized to retailer knowledge in a sneaky style. The one precise redemption key within the multisig that may spend the outputs is a burner: The artist doesn’t even have management of a corresponding non-public key. We name this system KeyBurn because it ensures that the information saved throughout the UTXO set can’t be eliminated by spending.
Bitcoin Stamps occur to be extraordinarily SIGOPS (Signature Operations) heavy on account of how the information is saved. Typical transactions don’t comprise so many SIGOPS, which has led some mining swimming pools to chop corners over time, and never rely them when together with transactions in a candidate block. Everyone seems to be conscious of the block dimension restrict, however do you know there may be an 80,000-SIGOPS restrict per block as effectively? I didn’t! I discovered this out when information first broke that F2Pool had created an invalid block that received rejected by the community for exceeding the SIGOPS restrict as a consequence of all of the Stamp transactions in it, which had been tied to very juicy mining charges. Costly mistake! Then they did it once more shortly after. That’s 6.25 BTC misplaced twice, not together with transaction charges.
How does this differ from Ordinal inscriptions? Effectively, I wish to say that Rodarmor got here up with essentially the most accountable answer for inscribing knowledge on-chain by inserting it within the SegWit witness knowledge construction. This can be a knowledge construction that’s been designed with optionality in thoughts: Don’t need it? That’s wonderful, as soon as your node validates the signatures, the information may be simply discarded. In reality, something earlier than an “Assume Legitimate”-marked block doesn’t have to be downloaded in any respect! Inscriptions are designed to respect the needs of node runners, and what did Rodarmor get for being so gracious?
OUTRAGE! HOW DARE YOU STORE YOUR JPEGS ON MY NODE!
Bitcoin Stamps takes a distinct, a lot much less well mannered, method. The information encoded within the bare-multisig will not be solely held in blocks, but additionally within the UTXO set as unspent outputs. This knowledge is rather more troublesome to “prune” as each node, by default, maintains a full copy of the UTXO set. So whereas inscriptions are saved in a blockchain-adjacent knowledge construction known as “the witness” which, by design, makes pruning straightforward, Bitcoin Stamps are saved in precise blocks within the canonical Blockchain knowledge construction in addition to the UTXO set held in reminiscence by each node.
Right here’s the way it breaks down:
Ordinal Inscriptions: saved by post-SegWit, full archival nodes solely. Pre-SegWit nodes won’t ever know that your stunning JPEGs even exist. Unhappy.
Bitcoin Stamps: saved by each node. Interval. Pre-SegWit nodes. Put up-SegWit nodes. Full Archival Nodes. Pruned SPV nodes. All of them get the Bitcoin Stamps. ALL NODES MATTER.
I wish to make this analogy: Ordinal inscriptions are like drawing with chalk on a sidewalk on a sunny day. Bitcoin Stamps is like spraying graffiti on the sidewalk. It’s very impolite and delinquent. It’s additionally very onerous to take away.
Now you is perhaps questioning: This sounds too good to be true, Mike, what’s the catch?
Effectively, there’s a catch: Everlasting storage on the blockchain will not be low cost. Bitcoin Stamps don’t make the most of witness knowledge so that they don’t profit from the witness low cost. As a rule of thumb, Bitcoin Stamps price not less than 4 occasions what Ordinals price to inscribe. However hey, you get what you pay for, amirite? And earlier than you accuse me of fear-mongering, there have been very actual discussions by numerous core contributors about altering the IBD (preliminary block obtain) default in Bitcoin Core in order that newly spun-up nodes by no means see your JPEGs within the first place.
As I write this, Luke Dashjr’s OCEAN mining pool has simply launched to a lot fanfare, and it seems that they’re purposely not relaying knowledge after OP_FALSE as a way of censoring Ordinal inscriptions.
And whereas there are some theoretical strategies of pruning Bitcoin Stamps out of the UTXO set, like UTreeXO, they’re much more invasive than discarding witness knowledge and include their very own trade-offs for full-node operators. Ordinals, magnanimously, make pruning straightforward whereas Bitcoin Stamps make it very onerous.
Bitcoin Stamps are much more costly to mint than Ordinals however we’ve discovered that constraints could make for good artwork. Within the phrases of Leonardo da Vinci: “Artwork lives from constraints and dies from freedom.” The artist group that’s sprung-up round Bitcoin Stamps are likely to gravitate in direction of pixel and SVG artwork as a result of they compress rather more effectively than raster artwork, for lack of a greater time period.
The dimensions/price constraint has additionally led to more moderen innovation by recursion the place a JSON file is minted that factors to numerous beforehand minted stamp “traits”. By repurposing these “traits”, the price of a big assortment is introduced down a number of orders of magnitude by stripping away the redundant knowledge throughout a set. Audio Stamps that mint solely a track’s notes (much like old-school MIDI format) and AI Stamps that mint solely a generative seed immediate are further revolutionary strategies that work across the constraints and ship novel outcomes.
You need fungible degen tokens? Yeah, we received these too within the type of SRC-20.
