Ord Alpha bitcoin · ordinals

We just released ord version 0.1.0!

ord is an ordinal number wallet and the index that serves ordinals.com.

This release of ord is by no means complete, but it now supports making ordinal-aware transactions on mainnet using the ord wallet send command thanks to @raphjaph, and boasts much faster indexing thanks to @callmeier.

ord wallet send

The ord wallet commands interact with an existing Bitcoin Core wallet using Core's RPC interface, and this release features a new send subcommand that constructs an ordinal-aware transaction to send a particular ORDINAL to a recipient's ADDRESS:

ord wallet send ORDINAL ADDRESS

We write extensive tests alongside every feature, but bugs can always slip through, and the project as a whole is still immature, so restrictions apply when using ord wallet send with Mainnet wallets.

ord wallet send will refuse to interact with a Mainnet wallet with a name other than ord, which does not start with ord-, to encourage users to explicitly mark wallets as being intended for use with ord.

Using bitcoin-cli wallet commands with an ord wallet risks spending your rarest and most exotic sats, and using ord wallet commands with your main wallet risks doxing your main stash if you assocaite a spicy ordinal with your identity.

Index Optimization

ord must build and maintain an index that maps transaction outputs to ordinal ranges. ord 0.1.0 now exploits the fact that many UTXOs are spent soon after they're created, and uses an in-memory cache to avoid huge numbers of database insertions and retrievals. ord uses the redb database, which is already quite fast, but using an in-memory cache avoids reads from and writes to redb's B-tree, which are more expensive than the in-memory cache's hashmap.

Backwards Compatibility

ord is still alpha-quality software, so breaking changes are inevitable, but starting with version 0.1.0, we'll indicate when breaking changes are included in a release by bumping the minor version number (0.x.0).

Try it out!

Check out ord 0.1.0 and let us know what you think! ord is CC-0-licensed open-source software developed on GitHub.

Ideas for a new Bitcoin testnet:

One of Bitcoin's core features is that coins have real-world value. A testnet with coins that have no value doesn't reproduce dynamics essential to Bitcoin, and doesn't encourage real-world use.


Competitive Governance markets · governance

I've been thinking about competitive governance, trying to dissect what, exactly, its desirable properties might be, and how to achive them. It strikes me that there are two separate desriable properties that governments have under competition, which, for lack of a better word, I'll call incentives and constraints.

Good incentives encourage governments to do useful things. Whereas constraints prevent them from doing harmful things, or cause governments to cease to exist if the do harmful things, or at least limit the harm that they can do.


Sending Ordinals on Signet bitcoin · ordinals

Raph and I have been working hard on ord, the ordinal block explorer and wallet, and have just finished the initial version of the ord wallet send ORDINAL ADDRESS command, which makes a transaction sending ORDINAL to ADDRESS.

Ordinal-aware Bitcoin transactions are rather tricky, and must attend to a number of considerations:

This requires a great deal of stressful fiddling with transaction input and output size and order, and a great deal of checks for edge cases. You can see all the gory details in the transaction builder.

All that fiddling has paid off, and today we made three transactions on signet:

ord wallet send will hopefully be much easier to use compared to using bitcoin-cli to manually construct ordinal-aware transactions. Give it a shot and let us know what you think!


Ordinal Theory bitcoin · computers · internet · cryptocurrency · ordinals

I've been working on a numbering scheme for satoshis that allows tracking and transferring individual sats. These numbers are called ordinals, and constitute a numeric namespace for Bitcoin. Satoshis are numbered in the order in which they're mined, and transferred from transaction inputs to transaction outputs in first-in-first-out order. More details are available in the BIP.

Ordinals don't require a separate token, another blockchain, or any changes to Bitcoin. They work right now.

Ordinals can be represented in a few ways:

With raw notation, like so 1905530482684727°. The number is the ordinal number, and the "°" is the Romance language ordinal symbol.

With decimal notation, like so 738848.482684727°. The first number is the block height, and the second is the index of the ordinal within the block.

With degree notation, like so 0°108848′992″482684727‴. We'll get to that in a moment.

A block explorer is available at ordinals.com. You can explore recent blocks, and look up ordinals by number, decimal, degree, or name.

Arbitrary assets, such as NFTs, security tokens, accounts, or stablecoins can be attached to Ordinals.

Ordinals is an open-source project, developed on GitHub. The project consists of a BIP describing the ordinal scheme, an index that communicates with a Bitcoin Core node to track the location of all ordinals, a wallet that allows making ordinal-aware transactions, a block explorer for interactive exploration of the blockchain, and functionality for minting ordinal NFTs.

Rarity

Since ordinals can be tracked and transferred, people will naturally want to collect them. Ordinal theorists can decide for themselves which sats are rare and desirable, but I wanted to provide some hints.

Bitcoin has periodic events, some frequent, some more uncommon, and these naturally lend themselves to a system of rarity. These periodic events are:

This gives us the following rarity levels:

Which brings us to degree notation, which unambiguously represents an ordinal in a way that makes rarity easy to see at a glance:

A°B′C″D‴
│ │ │ ╰─ Index of sat in the block
│ │ ╰─── Index of block in difficulty adjustment period
│ ╰───── Index of block in halving epoch
╰─────── Cycle, numbered starting from 0

Ordinal theorists often use the terms "hour", "minute", "second", and "third" for A, B, C, and D, respectively.

Now for some examples. This ordinal is common:

1°1′1″1‴
│ │ │ ╰─ Not first sat in block
│ │ ╰─── Not first block in difficutly adjustment period
│ ╰───── Not first block in halving epoch
╰─────── Second cycle

This ordinal is uncommon:

1°1′1″0‴
│ │ │ ╰─ First sat in block
│ │ ╰─── Not first block in difficutly adjustment period
│ ╰───── Not first block in halving epoch
╰─────── Second cycle

This ordinal is rare:

1°1′0″0‴
│ │ │ ╰─ First sat in block
│ │ ╰─── First block in difficulty adjustment period
│ ╰───── Not the first block in halving epoch
╰─────── Second cycle

This ordinal is epic:

1°0′1″0‴
│ │ │ ╰─ First sat in block
│ │ ╰─── Not first block in difficulty adjustment period
│ ╰───── First block in halving epoch
╰─────── Second cycle

This ordinal is legendary:

1°0′0″0‴
│ │ │ ╰─ First sat in block
│ │ ╰─── First block in difficulty adjustment period
│ ╰───── First block in halving epoch
╰─────── Second cycle

And this ordinal is mythic:

0°0′0″0‴
│ │ │ ╰─ First sat in block
│ │ ╰─── First block in difficulty adjustment period
│ ╰───── First block in halving epoch
╰─────── First cycle

If the block offset is zero, it may be omitted. This is the uncommon ordinal from above:

1°1′1″
│ │ ╰─ Not first block in difficutly adjustment period
│ ╰─── Not first block in halving epoch
╰───── Second cycle

Supply

Total Supply

Current Supply

At the moment, even uncommon ordinals are quite rare. As of this writing, 745,855 uncommon ordinals have been mined - one per 25.6 bitcoin in circulation.

Names

Each ordinal has a name, consisting of the letters A through Z, that get shorter the larger the ordinal is. They could start short and get longer, but then all the good, short names would be trapped in the unspendable genesis block.

As an example, 1905530482684727°'s name is "iaiufjszmoba". The name of the last ordinal to be mined is "a". Every combination of 10 characters or less is out there, or will be out there, some day.

Exotics

Ordinals may be prized for reasons other than their name or rarity. This might be due to a quality of the number itself, like having an integer square or cube root. Or it might be due to a connection to a historical event, such as ordinals from block 477,120, the block in which SegWit activated, or ordinal 2099999997689999°, the last ordinal that will ever be mined.

Such ordinals are termed "exotic". Which ordinals are exotic and what makes them so is subjective. Ordinal theorists are are encouraged to seek out exotics based on criteria of their own devising.

Archaeology

A lively community of archaeologists devoted to cataloging and collecting early NFTs has sprung up. Here's a great summary of historical NFTs by Chainleft.

A commonly accepted cut-off for early NFTs is March 19th, 2018, the date the first ERC-721 contract, SU SQUARES, was deployed on Ethereum.

Whether or not ordinals are of interest to NFT archaeologists is an open question! In one sense, ordinals were created in early 2022, when I finalized the Ordinals specification. In this sense, they are not of historical interest.

In another sense though, ordinals were in fact created by Satoshi Nakamoto in 2009 when he mined the Bitcoin genesis block. In this sense, ordinals, and especially early ordinals, are certainly of historical interest.

I personally favor the latter view. This is not least because the ordinals were independently discovered on at least two separate occasions, long before the era of modern NFTs began.

On August 21st, 2012, Charlie Lee posted a proposal to add proof-of-stake to Bitcoin to the Bitocin Talk forum. This wasn't an asset scheme, but did use the ordinal algorithm, and was implemented but never deployed.

On October 8th, 2012, jl2012 posted a scheme to the the same forum which uses decimal notation and has all the important properties of ordinals. The scheme was discussed but never implemented.

These independent inventions of ordinals indicate in some way that ordinals were discovered, or rediscovered, and not invented. The ordinals are an inevitability of the mathematics of Bitcoin, stemming not from their modern documentation, but from their ancient genesis. They are the culmination of a sequence of events set in motion with the mining of the first block, so many years ago.

There are a lot of things that I wish would happen, but don't have the time to actually do myself. I complain about such things all the time to basically anyone who will listen. Such efforts are all well and good, and sometimes actually pay off, but additionally, I'd like to materially support people who might actually do these things.

This post, which I'll try to keep up-to-date, if I remember, documents the projects which I wish some talented go-getter would take on, and in which I would invest money in if given the opportunity.

Upgrading Email computers · internet

Why?

Return email to its rightful place as the one true messaging protocol. It's this or use a dozen messaging apps for the rest of your life, there is no other realistic option.

How?

Add the features that make people use other messaging protocols to email.

Which features?

Contacts

Description: Chat, mobile notifications, read receipts, and other features, should not be available to arbitrary addresses. User approves addresses who can use these features.

Implementation: Add-to-contacts UI in client.

Degredation: N/A.

Chat

Description: Dedicated chat UI. No subject line. Return to send.

Implementation: Add dedicated chat UI to client. Messages sent from chat UI have header chat: true. Messages received with chat: true are shown in chat UI. Only chat from contacts appear in chat UI. Chat from non-contacts appears in message request UI.

Degradation: Message desplayed in inbox UI.

Mobile Notifications

Description: Some messages trigger mobile notification. User configurable.

Implementation: Mobile app has notification category for mail from contacts with header urgent: true.

Degradation: No mobile notification.

Read Receipts and Typing Indicators

Description: See read receipts and typing indicators on sent mail.

Implementation: Add receipt-endpoint: <URL> header to outgoing mail. Display read receipts and typing indicators sent to own receipt-endpoint. Only send read receipts and typing indicators to contacts.

Degredation: No read receipts or typing indicators.

Voice Calling

Description: Initiate voice calls from within client.

Implementation: Query MX server for voice call endpoint. Display voice call button next to conversations where MX server supports voice calls.

Degredation: No voice call button displayed when not supported.

Video Calling

Same as voice calling.

Message Requests

Description: Email from arbitrary senders should go into a message request folder, instead of in the inbox, to prevent phishing attacks, and encourage users to whitelist contacts which enables richer features.

Implementation: Email from senders who are not contacts goes into message request folder. Message request folder is distinct from spam folder.

Degredation: Email appears in main inbox.

Emoji

Description: Mail consisting of a small number of emoji is displayed in a larger font.

Implementation: Display mail consisting of a small number of emoji in a larger font.

Degredation: Emoji appear smol and sad.

Stickers

Description: Users can send "stickers" which are scaled appropriately.

Implementation: Display mail consisting of a single image scaled to UI.

Degredation: Images appear at fixed size.

Improved Rich Text Support

Description: Allow rich formatting without breaking plain text readers or using arbitrary HTML.

Implementation: Messages can indicate that they are formatted as markdown. Format messages for graphical clients and display with added line-breaks for plain text readers.

Degredation: Messages appear as plain text markdown, which is highly readable.

End-to-end Encryption

Description: Messages between users are end-to-end encrypted to avoid being read by third parties.

Implementation: Query MX server for public key of receipient, encrypt mail for recipient with pubkey.

Degredation: Messages are not encrypted. This is strict improvement to not encrypting any email. Once email E2EE is widespread enough, refuse to send mail to recipients that don't support it.

Prevent Replies Leaking Information

Description: Including messages in replies bloats messages, can accidentally leak information, and has is not necessary due to threaded clients.

Implementation: Don't include original message in reply by default. User may use dedicated quote reply UI to include quotes of original message.

Degredation: None.

Faster Message Delivery

Description: Deliver email instantly without any delay.

Implementation: Define mapping of email symantics over HTTP/3 as email/2, providing persistant connections and an efficient binary encoding. Query MX server email/2 support and use it if available, using persistant connections and binary encoding for instant message delivery.

Degredation: Messages are delivered at normal speed.

Disappearing Messages

Description: Messages can be configured to dissappear after some amount of time.

Implementation: Query if recipient MX server supports disappearing messages. If so, let sender set amount of time before messages disappear. Enforced by recipient, not sender, since sender enforcement is impossible.

Degredation: Option to turn on disappearing messages is not available when not supported by recipient.

Group Chats

Description: It should be possible to easily add and remove addresses from group chats.

Implementation: Email already supports group emails, but configuring adding and removing addresses from group chats is difficult. Query MX server for group chat support endpoint. Dedicated API for creating and updating group chats, referenced by ID. Group chat emails are associated with ID, instead of just being arbitrary lists of addresses, allowing any participant, if they have the permissions, to add and remove members from chat.

Degredation: Group chats are received as ordinary multi-address emails.


The Path to Email World Domination computers · internet

A letter to Maalika Manoharan, Product Manager, Gmail. Sent via LinkedIn Inmail, which is palpably ironic.

Hi Maalika,

My name is Casey Rodarmor, and I am a former Google SRE and SWE.

I am writing you today because you may be one of the few people that can deliver us from the multi-messenger hell that the human race finds itself in today. Everyone needs to use six or more messaging apps, and everyone hates it.

However, there is an easy way out of this. Email is a federated, decentralized, standards-based messaging platform that everyone already uses. The only reason people use other messaging protocols is because those messaging protocols have features that email doesn't have.

Here is the path to email world domination. It is very simple:

Add the features that email is missing, one by one, in a backwards compatible way.

These features include:

These features can all be implemented in backwards compatible ways that gracefully degrade when they aren't supported.

These features should be designed and implemented in an open process, involving the internet community, public RFCs, and implementations by multiple clients and service providers.

This is a major undertaking, but the benefit is huge, both for Google, Gmail, and the internet community.

Every single non-email protocol will fall by the wayside, and we can return to a simpler, more productive, and more secure world, one where everyone just uses email to communicate, an open, standards-based, internet native protocol.

This could be, without exaggeration, the most important work of your life.

Do you have time to discuss this with me? I have no agenda, just someone who thinks that this is possible, and ultimately very achievable.

With best regards, Casey Rodarmor


The Terrestrial Dividend markets · politics

Tax the land, pay the people.

The Terrestrial Dividend consists of a tax and a dividend. Revenue is generated with a tax on the unimproved value of land and distributed as a cash dividend to all citizens.

Why?

If You're in Favor of Wealth Redistribution

If you are in favor of wealth redistribution, you should want to raise as much money as possible, as fairly as possible, and get as much as possible into the hands of those who need it.

The Terrestrial Dividend accomplishes all of these goals.

If You are Against Wealth Redistribution

If you are not in favor of wealth redistribution, you should want revenue generation to be as efficient as possible, and to minimize the negative economic impact of distribution. Additionally, you should want wealth redistribution to be done in such a way that if it is harmful, incentives align to reduce it.

The Terrestrial Dividend accomplishes all of these goals.

The Terrestrial Tax

The Terrestrial Tax is economically efficient. The supply of land is fixed, so a tax on the unimproved value of land does not prevent the production of more land. A tax on widgets, on the other hand, reduces the incentive to produce widgets.

The Terrestrial Tax is progressive. Land is owned by the wealthy, so the wealthy would pay a much greater share of the tax. Due to the fixed supply of land, the tax cannot be passed on to tenants.

The Terrestrial Tax respects privacy. The government does not need to know who owns what land, or what they are doing with it. The tax can be collected with anonymous payments, and only in the case of non-payment must the government involve itself.

The Terrestrial Tax cannot be avoided. It is impossible to hide land or disguise use of land.

The Terrestrial Tax encourages productive economic activity. Since the tax is levied on the unimproved value of land, under-utilized land is a liability, and will be brought into productive use or sold, not held as a speculative asset.

The Terrestrial Tax is simple. Income, sales, value-added, and corporate taxes require enormously complex and err-prone reporting. The details of these taxes are the source of endless political litigation. Under the Terrestrial Tax, the only complexity is in fairly valuing the unimproved value of land, clearly an easier task.

The Terrestrial Tax is legible. The negative effects of a too-low or too-high tax rate can be observed and the rate corrected.

The Terrestrial Dividend

The Terrestrial Dividend is beneficial. Cash is more useful in all circumstances than in-kind payments of the same value. The people who need help will get the most benefit possible.

The Terrestrial Dividend is fair. All citizens receive equal-sized cash payments. There is no need to exclude certain recipients, since the wealthy will already pay more tax than they receive as dividend.

The Terrestrial Dividend is efficient. Cash payments avoid the overhead of defining the details of and administering in-kind benefits.

The Terrestrial Dividend is what people want. People prefer cash over in-kind benefits of the same value.

The Terrestrial Dividend is unobtrusive. It is not means tested, nor does it require an application. The poor are the least equipped to fill out applications and submit documentation of income, so this ensures that even the very worst off have the best chance of receiving benefits.

The Terrestrial Dividend is legible. The negative effects of a too-low or too-high dividend can be observed and the amount corrected.

Together

The Terrestrial Tax and Dividend are good policies on their own, but even better together due to aligning incentives.

If you want to increase the amount of the dividend, you should want to increase the value of all land, so that the dividend can be increased.

If you want to reduce the amount of the tax, you should want to increase the value of all land, so the tax rate can be reduced without reducing the divided.

Under the Terrestrial Dividend, everyone should care about reducing government overhead and waste, because it comes out of their own pockets.

Also, everyone should care about removing bad policies and implementing good ones, because they increase the value of all land and make everyone better off.

Tax the land, pay the people.


Coin IDs cryptocurrency

Good evening list,

This mail is inspired by Chia's coin IDs. Chia coin IDs consist of:

sha256(parent id, sha256(scriptpubkey), amount)

One consequence of this is that outputs in Chia have a dedicated textual ID. This seems beneficial, separate from any larger technical consequences, and made me wonder if we couldn't replicate that in Bitcoin.

Outputs, a.k.a. outpoints, are commonly represented as TXID:INDEX. For example, the first output of transaction c7dd35a4f81977feac0d235d0e77265cacd362bfc2f0246e384a80d3b0a53a9b is represented as c7dd35a4f81977feac0d235d0e77265cacd362bfc2f0246e384a80d3b0a53a9b:0.

I find this representation unsatisfying:

I propose a dedicated representation of outputs using Bech32m. Bech32m is especially legible, due to its human-readable part, and is compact, and easy to type and verify. Although having error correction doesn't seem absolutely necessary, it doesn't seem like a downside. The representation uses "coin" as the human-readable part, with the payload being the transaction ID, followed by the 4 byte index.

For example:

c7dd35a4f81977feac0d235d0e77265cacd362bfc2f0246e384a80d3b0a53a9b:A0

Becomes:

coin1clwntf8cr9mlatqdydwsuaextjkdxc4lctczgm3cf2qd8v9982dsqqqqqqqenjt7

Anacdotally, I find that many non-expert users I talk to think and talk about Bitcoin as if it were an account-based system, and tend to think in terms of transactions. I wonder if having coin IDs, in the form I propose or in some other form, would help remedy this, similar to how transaction ids, block hashes, and addresses help reify those concepts. The particulars of the representation are of secondary importance.

Best regards,
Casey Rodarmor

Configuration computers

Conventional software configuration is backwards.

If you want an HTTP server to listen on port 80 and serve some directory full of files, you tell the service to bind to port 80 and pass it the path of the files to serve:

$ http-server --port 80 --files /srv/www
Serving `/srv/www` via HTTP on port 80.

This is backwards. Let's call this kind of configuration "internal configuration", because it's configuration that happens inside programs.

Instead, processes should declare a namespace of resources that they consume or produce:

$ mount http-server /http
Mounted `http-server` instance at `/http`.
$ tree /http
/http
  /socket
    /listen
  /imports
    /files

After mounting, resources would be mapped as you see fit, from outside the process, without having to stop or reconfigure the service:

$ listen 80 /http/socket/listen
Connections to port 80 are being forwarded to socket `/http/socket/listen`.
$ export /srv/www /http/imports/files
Filesystem `/srv/www` exported to `/http/imports/files`.

Let's call this "external configuration", because it's configuration that happens outside programs.

External configuration has a number of benefits:


Wound Care medicine

Got some minor cuts and scrapes while doing water sports (not the fetish kind you perv), was curious about the optimal way to dress them, which lead to reading at least a dozen papers and articles on wound care and dressing selection.

It is a complex and interesting topic! Here is my probably-inaccurate summary:

The four stages of wound healing are hemostasis, inflammation, proliferation, and maturation.

Hemostasis is the body's immediate reaction to and stabilization of the wound. Blood clots and stops flowing from the wound. Or doesn't, in which case hemostasis is the first and last stage of wound healing.

Inflammation comes next, which includes processes that prevent infection and initiate healing. Injured blood vessels leak transudate (water, salt, and protein) white blood cells head to the wound, tissue turns red and swells, and bacteria and dead cells are removed from the wound.

Proliferation is the phase where the bulk of tissue reconstruction and healing takes place. Lost tissue grows back, and the wound closes. In the final phase of proliferation, epithelial cells regrow and cover the wound.

Maturation, also called remodeling, is the finalization and cleanup phase. The plumbers, electricians, and carpenters leave the building site, and all the loose ends are tied up. Temporary cells die off via apoptosis, and the new tissue reorganizes and strengthens.

The appropriate dressing depends on the characteristics of the wound, and so, as you might imagine, there exists a rich terminology for wound description.

A sloughy wound is with a layer of infected gunk, usually yellow, You've probably noticed this when you've had an infected scrape. Slough is dead tissue that must be removed for the wound to heal, and a sloughy wound should be covered with a moist dressing that allows the slough to liquefy. I gather that mechanical debridement of slough, e.g. the use of wet-to-dry dressings, although still widely used, is no longer a standard of care.

A necrotic wound has some amount of dead skin or flesh covering or surrounding the wound, usually of a ghastly black color. If necrotic tissue is badly infected, it should be surgically removed. However, since this is invasive and destructive, the preferred alternative for the removal of non-infected necrotic tissue is the use of a moist, occlusive dressing promoting autolytic debridement, the natural separation of viable and non-viable tissue.

A granulating wound wound in the process of healing. It has a nice bright, healthy red color, and should be covered in a moist occlusive dressing and left to heal.

An epithelial wound is in the final stages of healing, with new skin growing over and covering the wound.

Interesting tidbit, if a wound is deep, it should be packed with some kind of dressing, to prevent premature wound closure before the wound void fills in with new tissue.

For my own rather boring although mildly sloughy wounds, I went with hydrocolloid dressings. Hydrocolloid dressings are occlusive dressings which create a moist environment for wound healing. As they transition from sloughy wounds to granulating wounds, I might switch to just using a film dressing, which are more flexible, comfortable, and durable.

After all this, I'm a little bummed that I don't have much weirder, graver, more complicated wounds that would demand more complex and interesting care. 😂


Lightning Mints cryptocurrency · internet · computers · markets

Federated blind mints have attractive privacy, scaling, and security properties that are highly complementary to those of Bitcoin and the Lightning Network.

I originally became interested in blind mints while thinking about Lightning Network wallet usability issues. When Lightning works, it is fantastic, but keeping a node running and managing a wallet present a number of challenges, such as channel unavailability due to force closes, the unpredictability of the on-chain fee environment, the complexity of channel backup, and the involved and often subtle need to manage liquidity.

All of these problems are tractable for a skilled node operator, but may not be soluble in the context of self-hosted wallets operated by non-technical users, hereafter normies. If this is the case, then normies may have no choice but to use hosted Lightning wallets, compromising their privacy and exposing them to custodial risk.

Chaumian mints, also known as Chaumian banks, or blind mints, offer a compelling solution to these problems, particularly when operation is federated. Chaumian mints, through the use of blind signatures, have extremely appealing privacy properties. The mint operators do not know the number of users, their identities, account balances, or transaction histories. Additionally, mint transactions are cheap and can be performed at unlimited scale.

Mint implementations, typified by eCash, have hitherto been centralized, and thus, like all centralized, custodial services, expose users to custodial risk in the form of operator absquatulation and mismanagement. To fix this, mint operation can be federated, with all operations performed by a quorum of nodes controlled by different parties.

Despite these interesting properties, Chaumian mints have largely been forgotten. This post gives an excellent overview of the phenomenon. I believe that Chaumian mints are currently severely underrated in general, and in particular deserve consideration as a potential avenue for improving custodial Lightning Network wallets.

Compared to a naïve hosted Lightning Network wallet, a service operated as a federated Chaumian mint offers excellent privacy, usability, security, and scaling.

Privacy: Privacy leaks from a Lightning mint come in two forms, internal and external, when a mint operator or an outside actor, respectively, observes sensitive information.

Blind signatures protect against internal privacy leaks, making them a strict improvement in that respect over custodial Lightning wallets.

When compared to a single-user Lightning network wallet, Lightning mints also protect against external privacy leaks. If the activity of a single-user Lightning Network wallet can be observed, which is possible but non-trivial, all such activity is preemptively that of the owner of the wallet. However, similar to a standard custodial Lightning Network wallet, any observable Lightning Network activity of a Lightning mint is the aggregate activity of its users, who thus form an anonymity set. If the number of users, and thus the anonymity set size, is large, external privacy leaks are also prevented.

Usability: Compared to a self-managed Lightning Network wallet, and similar to a standard custodial Lightning Network wallet, Lightning mint wallets offer superior usability. A user need not be concerned with the details of node operation or channel management, and can deposit to and withdraw from their account with standard Lightning Network invoices.

Security: The security of a Lightning mint is weaker than that of a self-hosted wallet. A quorum of federation members can abscond with funds. However, compared to a standard custodial Lightning Network wallet, security is greatly improved. Additionally, federation members might be located in different jurisdictions, making the mint robust to regulatory interference. Furthermore, members might be entities with online reputations, such as anonymous Bitcoin Twitter users with an established history of productive shitposting, providing further assurances against mismanagement and fraud.

Scaling: Mint operations are extremely lightweight, similar to Lightning Network transactions, so scaling properties are similar to the Lightning Network itself. Additionally, users need not manage their own channels, so a well-capitalized federation can open channels efficiently, lowering the per-transaction channel management overhead.

Interoperability and market dynamics: Additionally, my hope is that such systems will be developed with a standardized protocol for communication between wallet interfaces and mint backends. This would allow users to use different backends with the same local wallet interface, encouraging competition in the market.

For more discussion of Chaumian mints and their applicability to Bitcoin, see fedimint.org. Elsirion, the author, is also at work on MiniMint, a federated Chaumian mint with Bitcoin and eventually Lightning Network support.

To close with a bit of speculation, I believe that Chaumian mints were never of particular interest or importance because they were limited to interoperating with the fiat currencies of the time. With the ascendance of Bitcoin, mints now have access to a powerful, decentralized, and uncensorable currency , made economical and fast by the Lightning Network.

I believe this layering of Chaumian mints on top of Bitcoin and the Lightning Network will, in the fullness of time, be demonstrated to be enormously powerful, and make Chaumian mints themselves worthy of renewed study and consideration.

Bitcoin will greatly reduce the power of the state, which rests entirely on its capacity for violence. This capacity is maintained by paying and equipping people to commit violence on its behalf, and it acquires the resources to do so by printing money, collecting taxes, and issuing debt.

Symmetry fiction

I don't do as much deep thinking as I used to. When I was a kid, I remember imagining what it would be like if the universe was symmetrical, mirrored right down the middle. I imagined a white room, floating in space, right on the plane that separates the two halves of the universe. If you parked your spaceship outside and opened the door, you would see yourself in front of you, opening the same door. It would be the you from the other side of the universe.

Wanko Manko fiction · shitpost

Thought of a hilarious idea for a manga and eventually anime when it inevitably gets super popular.

It takes place in Japan, but only because that seems like the only appropriate setting for an anime.

The story is about a twenty-something bachelor. He wants a dog, so he adopts a beautiful female malamute from a shelter.

However! When he gets home, he realizes that the dog has the most beautiful human-looking vagina he has ever seen. Like, all-time-top-voted-post-on-r/godpussy tier. Of course, since it's an anime, you only ever see it pixelated.

Then, basically the entire show revolves around him trying to resist the temptation to fuck his dog, and situations that make it hard to resist temptation. His catchphrase is "Inu ni makemasen!" / "I won't lose to the dog!"

Like, for example, in one episode he leaves out a jar of strawberry jam, and the dog gets into it, and then when the dog is done eating the jam, it pulls its snout out of the jar, and there's strawberry jam on its mouth in the exact shape of sexy lipstick. This of course sends him into a fit of desire, and he has to like, I dunno, take a cold bath, or watch sumo wrestling or something to resist.

In the final episode, he's taking the dog for a walk in a dog park, and he sees another dog running around, and notices that it has a huge, beautiful human penis. (Pixelated, natch.) He then look over and sees its owner, who's a beautiful woman his age. They lock eyes and instantly fall in love.

I can't decide if it's a happy ending, where he gets this great girl and the two dogs with beautiful junk get each other. Or if it's a darker ending, where he has sex with the woman for the first time and her pussy is absolutely ruined, and he realizes that she hasn't resisted temptation and has been getting railed on the reg by her dog and its huge human cock. Or afterwards he asks her how it was, and she says "It was okay…" in a super wistful voice, and then looks over at her dog, while the color drains from his face as he realizes the truth.

I'm not sure whether it should be called Wanko Manko, which means "Dog Pussy" in Japanese but rhymes, or Venus in Fur, as a play on Venus in Furs by Leopold von Sacher-Masoch.


For some reason I'm fascinated by the debris in this vacuum product photo. If you look closely, you can see that it's several specific kinds of debris. Uncooked grains of rice, sunflower seeds, maybe coffee beans, and clumps of hair. I'm imagining some intern getting just the right debris ready for the photo.

Policy For Manufacture politics

The complex priority system that the state is using in many countries to roll out the covid vaccine is reminiscent of this plane boarding algorithm:

Yes, it is optimal. No, it won't work in real life.

The state, of course, ignores this. Its reach exceeds its grasp, and we are left with fragile, sub-optimal, poorly implemented plans that are, without exaggeration, worse than a free-for-all, and much worse than market allocation.

The state makes the same mistake in all spheres, because it makes no distinction between designing policy and implementing policy.

The opposite of this is design for manufacturing, where designers of a product modify a design with manufacturing constraints in mind, even if it makes the design worse on some axes. The final outcome, of course, is substantially better.

The product is subject to fewer delays, costs less, and can be made in higher quantities.

However, we cannot expect the state to grasp this simple wisdom, for it is utterly bereft of the incentive to do so.


Haircut Numbers internet

I was trying to find an image reference for what different clipper guard lengths look like. Every single reference I found had different models with different hairstyles, or used illustrations instead of photographs.

After searching a bit, I found this video, which shows the same person with different hair lengths, with the hair uniformly short over the whole head.

I think it's quite interesting that a random YouTuber may have created a best-in-the-world reference, even if it's for something as mundane as haircut lengths.

Sex Sells markets

As an unrepentant degenerate and fan of microeconomics, it should come as no surprise that I find the online sexual economy endlessly fascinating.

Most of what happens there isn't surprising to me, with the exception of pricing for online sexual services, which is much higher than I would have expected.

As an example, take private, one-on-one cam shows. Browsing reddit.com/r/sexsells, the going rate seems to be between $2.50 and $5.00 per minute, or $150 to $300 per hour.

This is mysterious to me.

Looking at ads on eros.com, offline prostitutes seem to charge $300 an hour. This isn't the amount advertised for a one hour session, but the marginal difference in price between a one hour and two hour session, and thus a reasonable estimate of the hourly rate, when preparation and travel are factored out.

Given that private cam shows are legal, can be done at home, and require minimal equipment; while offline prostitution is physically dangerous, illegal, unpleasant1, and highly taboo, it seems strange that they are priced roughly the same.

A priori, I would have expected a price difference of 10× or more, like $300 per hour offline and $30 per hour on cam.

Advice For Programmers programming

In an October 1935 article in Esquire. Hemingway offers this advice to a young writer:

The best way is always to stop when you are going good and when you know what will happen next. If you do that every day when you are writing a novel you will never be stuck. That is the most valuable thing I can tell you so try to remember it.

Reformulated for programmers and equally valuable:

The best way is aways to stop when you are going good and you have just written a failing test. If you do that every day when you are writing a program you will never be stuck. That is the most valuable thing I can tell you so try to remember it.

If you start programming for the day, a failing test to fix will get you right back on track.

Instead of having to muster willpower to get started and brainpower to figure out what you were doing and what to do next, you can mindlessly do whatever it is that will fix the test.

After that, you'll be much more likely to be in the flow of things, and be able to keep going in good spirits.


Equitable Auction markets

The PS5 was released about a week ago, and, predictably, it is impossible to get one. All retailers, online and IRL, are sold out. Of course, consoles are available on Ebay at ruinous prices, so at least the scalpers are doing well.

Economists, of course, are wringing their hands and mumbling about Vickrey auctions. What Sony should do, they mutter, is to hold a daily auction for PS5s, and let the market decide the price.

The economists are, of course, quite right. If Sony auctioned off PS5s there would be no lines, no scalpers, and no uncertainty. You could put in a bid at the price that you wanted to pay, and then simply wait until demand had died down for your bid to be filled. As a bonus, Sony would make more money for producing something that people wanted to buy, and more capital to ramp up production.

Unfortunately, the economists don't get their say here, because of their arch enemy, non-economists. Non-economists, or, normal people, as they are otherwise known, as far as I can tell, don't understand that there is such a thing as an inescapable trade-off. They want everyone to get a PS5, everyone to pay MSRP for it, there to be no scalpers, nobody to ever make a profit from demand exceeding supply, and all things to be fair, based on confused and self-contradictory conceptions of unfairness.

So, companies can't hold auctions for scarce goods, and have to set an MSRP, produce whatever they can, and hope for the best.

I wonder though, if there might be some way for a company to hold an auction for their products, but in a way that would be perceived as fair.

Here is one possible setup for such an auction, using Sony as the example company, and the PS5 as the example product:

Essentially, any time someone pays over MSRP for a PS5, they ensure that eventually, someone will get a PS5 for less than MSRP. If someone rich or impatient buys a PS5 for $1000, two less impatient people can eventually buy PS5s for $250.

I think, perhaps, this would be perceived as fair. But, with real people, you never know.

Just: How I Organize Large Rust Programs programming

One of the things that I personally struggled with when learning Rust was how to organize large programs with multiple modules.

In this post, I'll explain how I organize the codebase of just, a command runner that I wrote.

just was the first large program I wrote in Rust, and its organization has gone through many iterations, as I discovered what worked for me and what didn't.

There are some things that could use improvement, and many of the choices I made are somewhat strange, so definitely don't consider the whole project a normative example of how to write rust.

Lexiclean programming

I just published a simple crate that performs lexical path cleaning: lexiclean.

Lexical path cleaning simplifies paths by removing ., .., and double separators: //, without querying the filesystem. It is inspired by Go's Clean function, and differs from the Go version by not removing . if that is the only path component left.

I implemented this for a command line utility I'm working on, but split it off so others could use it.

There are a few reasons I prefer lexical path cleaning to fs::canonicalize:

There are some reasons you might prefer fs::canonicalize:

Are there any other reasons to prefer one over the other? I'd love to hear them!

It is very lightly tested! If you intend to use it, I encourage you to submit additional tests containing paths you might encounter, if you think the existing tests don't cover them. In particular, I haven't thought about all the exotic prefixes that Windows paths might be adorned with, so there might be bugs there.

I don't expect to modify the crate or add features to it beyond what I need for my own purposes, so if there are additional features you want, please consider opening a PR! Of course, if you find a bug, I will happily fix it.


Uninsurance markets

From Scott Alexander on the Amish health care system:

The Muslims claim Mohammed was the last of the prophets, and that after his death God stopped advising earthly religions. But sometimes modern faiths will make a decision so inspired that it could only have come from divine revelation. This is how I feel about the Amish belief that health insurance companies are evil, and that good Christians must have no traffic with them.

The post is about the advantages of the Amish health care system, which seems to have much lower costs and equal effectiveness when compared to conventional American health insurance centered health care.

The post is gripping (well, at least if you're interested in why American health care is so expensive), so I recommend reading it. But briefly, the Amish seem to have much lower costs with the same quality of care due to:

I wonder if much of this could be replicated with, not an insurance plan, but, something else… an "uninsurance plan":

I suspect that such a plan would be very cheap, to make a number up, perhaps no more than $10 per month. If it were only $10 per month, and members got an HSA, they might want to join just for that. And, if they got insurance-negotiated rates when paying out-of-pocket while being uninsured, the would almost certainly be willing to pay for it.

Such an uninsurance plan would encourage consumers to plan ahead, shop around, and save for medical expenses in their HSA, maybe giving them health care approaching that of the Pennsylvania Dutch.

Intermodal sharing · programming

TL;DR

Intermodal is a new command-line BitTorrent metainfo1 utility for Linux, Windows, and macOS. The binary is called imdl.

It can create, display, and verify .torrent files, as well as generate magnet links.

demonstration animation

It has lots of features and niceties, is easy to install and run, and is hopefully just the beginning of an ambitious project to make decentralized content sharing better.

Features include:

You can install the latest version of imdl to ~/bin with:

curl --proto '=https' --tlsv1.2 -sSf https://imdl.io/install.sh | bash

Development is hosted on GitHub, where you can find the code, the issue tracker, and more installation options.

Give it a try and let me know what you think!

I'm eager to hear what works, what doesn't, and what features you'd like to see added. I'll be working on novel functionality—more on that below—and I'd love to hear your critical feedback and ideas.

You can get in touch by open an issue, joining the discord server, or sending me an email.

Happy sharing!

Popcorn Time Should Become a Browser programming

I am not a lawyer. This is not legal advice.

Popcorn Time-style video streaming apps seem to be vulnerable to legal action by rightsholders.

For example, the popcorntime.sh domain was recently suspended, and the operator of a site which merely provided information about how to obtain and use Popcorn Time was sentenced to prison.

Although given that Popcorn Time's servers do not themselves host infringing content this may seem a bit unfair, it is simply the reality of the world we live in.

It is interesting to note, however, that although web browsers can be used in exactly the same way as Popcorn Time, namely searching for and viewing copyrighted movies, the developers of web browsers have thus far not faced successful legal challenges.

Structural Heterogeneity cryptocurrency

Investing in cryptocurrencies is not the same as buying simple equity in a company.

Although each company has a different business model, they and the equity they issue are largely structurally homogeneous. They hold their monies in banks, pay for their expenses with wire transfers and cheques, follow prescribed rules of accounting, and issue stock that operates according to well understood rules. This is not to say that said practices are good or bad. They are simply a known factor.

Cryptocurrencies and tokens, however, are structurally heterogeneous. They have different codebases, modes of operation, levels of complexity, and security models. Although broadly lumped into the same category, they can, by the nature of these differences, have almost nothing in common.

Investing in one is like buying stock in a company with novel business models, banking practices, and accounting methods, and furthermore whose stock is issued under a bespoke scheme and follows unique trading rules.

Accordingly, a much, much greater level of care is required when making such investments. If any one of these novel mechanisms fail, your investment may go up in billowing smoke and flames overnight.

This is not to say that you should completely avoid cryptocurrencies and tokens, just, you know, do your homework.

Delinearization programming

Programs first crawled from the murky oceans as simple lists of instructions that executed in sequence. From these humble beginnings they have since evolved an astonishing number of ways of delinearizing.
