Blockchain, Crypto, NFTs etc

This is a public Zettelkasten overview (see FAQ) on the blockchain and adjacent concepts.

Created 12/11/2021. Last updated: 20/11/2021.

A long overdue overview, just getting started. Stimulus: the idea of managing the MyHub data union and associated services using a DAO and utility token. Currently I'm curating a few articles every day, then summarising the most interesting ones here every week (cf progressive summarisation).

Related ideas not in this Overview: decentralised, p2p.

How to explain Bitcoin to your grandmother :

  • banks are simply "intermediaries that 'keep score' of e-money" by maintaining a time-stamped ledger.
  • "we have to trust in the banking system in order to trust in the money." Bitcoin is a decentralised intermediary that we don't have to trust: people can't copy/paste bitcoin.
  • Everyone has a Public Key, linked to bitcoins. To send someone bitcoins, I broadcast to the Bitcoin network: "I am Public Key M; I wish to transfer X Bitcoin to Public Key N. Please check and record it on the ledger",
  • that ledger is "the Blockchain... a computer file that gets constantly updated, and it is held on the computers of everyone in the Bitcoin network... built and maintained by ... Miners", who (competitively) earn bitcoins in return for validating and recording transactions. So Bitcoin is "a currency that grows in the process of people trying to maintain its integrity".
  • Recording to the blockchain "makes the transaction real... coins [exist] in the historical record of the blockchain... a collaboratively-built knowledge bank ... All I have on my computer is a public key which says that I am the rightful owner to a part of that history" - so dont lose access to your Key!

Ethereum is a platform and a programming language ... to build and publish next-generation distributed applications.... Ethereum can be used to codify, decentralize, secure and trade just about anything... Ethereum borrows the concept of decentralized consensus that makes bitcoin so resilient, yet makes it trivial to build on its foundation

Based on charters taking the form of code on a peer-to-peer network, these are entities that could automate many of the tasks of a conventional organization with varying levels of human input.

Blockchain + private key cryptography allow for “self-sovereignly”: full possession of digital assets without having to trust a third party. Wallets can be multi-signature: have as owners multiple keys (incl. other wallets), & require multiple key signatures to confirm a transaction. They allow cooperatives to hold resources in common, and liquid democracy (through delegation). Multi-sig accounts = operating system for DAOs, presuppose groups or identity collections as their primary unit -> composable identity. Web 3.0 accounts will underpin #metaverse interoperability: provide wallets, identity, login functions and in-game inventories (holding assets, including identities), complete with cross-platform narratives & reputations. Inventories can be cooperatively shared - Inventories, Not Identities


blockchains encourage data sharing among traditional silos, if there is enough up-front benefit ... AI with blockchains unlock the possibility for AI DAOs - an AI that owns itself... can accumulate wealth, that you can’t shut off... an AGI-style control system running on a decentralized processing & storage substrate. Its feedback loop continues on its own, taking inputs, updating its state, actuating outputs, with the resources to do so continually... AI gets its missing link: resources. DAO gets its missing link: autonomous decision-making.
Blockchains for Artificial Intelligence


"Scarcity — the quality that gives offline art its value — was hard to replicate online. An NFT is a digital collectible item stamped with a unique bit of code that serves as a permanent record of its authenticity and is stored on a blockchain... can be bought and sold ... can’t be deleted or counterfeited. That makes it useful for artists... to create limited edition digital goods... Creators can even attach a royalty agreement to their NFTs, entitling them to a cut of the profits every time their assets are resold".

Brave, the blockchain-based browser initiative that raised $35 million in an ICO earlier this year, is making its first major move to build an ecosystem that rewards publishers in a new kind of way.

An ecosystem of micropayments... the holy grail for online journalism...

an ad-free publishing economy on Civil’s Ethereum-based platform... accountable to its readers ... impervious to the interests and agendas of advertisers or other intermediaries or “influencers” ... Readers, and readers alone, provide our community, our platform, and the funding ... Commenters can earn tips on the Civil platform, so there will be a point to being smart and careful about what you write... Imagine adding information to a news story you’re interested in, and not just getting thumbs up or ‘likes’ for it, but getting paid for it

The same arguments regarding scarcity and digital that apply to media, above, also apply to digital art, with artists getting a share of resale, creating a perpetual revenue stream for successful artists and their descendants. But artists push things further than turning a newspaper column into a NFT: "The Fingerprints DAO collection is composed of NFTs that revolutionized the use of smart contracts as art" - including art which is created algorithmically, using the minting tmestamp among other datapoints as an input, and which can evolve over time.

Interesting #defi play by investors who bought 20 of beeple's "Everyday" NFT pieces for $2.2m, built virtual 3D museum galleries to display them, created 10 million B20 tokens, each representing a fractional ownership of the nfts: 10% went to the museum artists, 2% to Beeple, they kept 50% and put some up for sale. B2O peaked at $27m.


OP Arcadeis a HTML5 game platform, with tournament competitions, to which game developers contribute games which are transformed into fractionalized NFTs. Buyers collect them to co-own games. Players can play for free (?) - via the DAO, "game owners make proposals, vote for game updates, fund additional development". Overall, a community: "players, game owners and developers working together to shape the future of their collectively owned games."

Social media / Fediverse

The model proposed in Protocols, Not Platforms: A Technological Approach to Free Speech (Nov. 2020) puts content moderation at the network edge, not the platform-owned centre. This edge could be the servers running the protocol according to rules the server owners' set up (classical fediverse model); the users themselves (fiddling with client preferences), and/or third parties, where users "subscribe to moderation filters or even add-on services ... let a million content moderation systems approach the same ... content—each taking an entirely different approach—and see which ones work best " (cf the "market of competing indicators" in We need a credibility indicator marketplace to fight disinformation, May 2018).

As for user dataprivacy: "just as the filtering decisions could move to the end users would simply build their own “data stores” [and] "offer up their data in exchange for access or deals" - cf Solid. And now add in cryptocurrency-based equity: the more you use, the greater your share of "the value of the overall network... As more people use the protocol [it] increases in value... an organization in charge of the protocol retains some percentage of the currency while distributing the rest".

Crypto-anarchists are mostly computer-hacking, anti-state libertarians ... believe that digital technology, provided citizens are able to use encryption themselves, is the route to a stateless paradise... build software – think of it as political computer code – that can protect us online... Most of us chase their latest shiny toys and have no real understanding of what we’re doing... an entire nation could one day be provided online via an uncontrollable, uncensorable digital network, where groups of citizens could club together to privately commission public services.

Finance: DeFi

Decentralised Finance: DeFi.

Ohm is a crypto reserve currency. Owners set policy via the OlympusDao. Ohm tokens are backed by a treasury of other cyrptocurrencies. The DAO mints & sells more to increase supply if the value of ohm rises above the treasury value, and buys back and burns Ohm if its value drops. Hence a stable floating value which never dips below the value of the backed assets in the treasury. It also buys bonds for its treasury in return for ohm at a discounted price.
