Foundations of Decentralization Vocabulary Flashcards

A comprehensive set of vocabulary flashcards covering the historical, technical, and governance foundations of decentralization, based on the provided lecture notes.

Lebombo bone

A tally stick from 40,000 BCE that represents one of the earliest forms of information storage.

Maat

The Egyptian system of virtue where autonomous priests interpreted transcendental values over rigid rules to maintain political stability.

Rule of Virtue

A legal approach, often associated with Confucianism, where society informally supports moral precepts more than explicitly defined legal precedent.

Legalism (Fajia)

A Chinese school of thought advocated by Shang Yang that emphasized rigid laws, known as the "letter of the law," based on the belief that people are basically evil.

Qin Dynasty

A centralized state (350–221 BCE) that implemented standardization of language and currency but collapsed 15 years after unification due to the brittleness of its rigid hierarchy.

Nant'án

Leaders within the Apache Resistance who led by example rather than coercion, facilitating a politically decentralized structure.

Principal-Agent Problem

A challenge faced by the 11th-century Maghribi Traders regarding how to manage agents over vast distances without modern technology, solved through a decentralized reputation system.

Metcalfe's Law

A principle stating that a network's value grows proportionally to the square of its users: $n^2$.

Wisdom of crowds

The process of collecting and analyzing data from millions of ordinary users to identify trends and solutions that would be invisible to centralized systems.

PageRank

Google's revolutionary algorithm that ranks web pages based on their link structure and authority, interpreting links as "votes."

Access Over Ownership

A core shift in consumer behavior within the sharing economy where individuals temporarily access assets through digital platforms rather than purchasing them.

Platform Company

A business that provides a technical foundation enabling direct interactions between customers, such as Substack or eBay, rather than following traditional linear supply chains.

Faustian bargain

A deal where users trade ownership and control of their data for the convenience and "free" services provided by Web 2.0 platforms.

Copyleft

A legal mechanism used in the GNU General Public License (1989) to ensure software remains free and open for users to modify and distribute.

P2P (Peer-to-Peer)

An architecture where users share resources directly between each other without relying on centralized servers, such as BitTorrent or Tor.

Immutability

A core principle of blockchain stating that the recorded history of transactions never changes.

Proof of Work (PoW)

A consensus mechanism where nodes compete to find a hash output with enough leading zeros by trying different "nonces," requiring approximately $18 \times 10^{12}$ attempts per win.

Proof of Stake (PoS)

A consensus alternative where validators lock money in smart contracts to be selected for block creation, eliminating energy-intensive mining.

Zero-knowledge proofs (ZKP)

Cryptographic tools that allow users to prove they know specific information without revealing the information itself.

Sharding

A network partitioning technique where nodes only process a subset of total transactions to improve blockchain scalability.

Path Dependencies

The tendency for technologies to remain in use due to institutional inertia or switching costs even after more efficient alternatives emerge.

Rational choice

A choice made by an agent with complete and transitive preferences who aims to maximize utility.

Condorcet's Paradox

A phenomenon where majority rule voting leads to non-transitive collective cycles (A>B>C>A) even if individual preferences are rational.

Arrow's Impossibility Theorem

A 1951 proof stating that it is mathematically impossible to design a perfect voting system that satisfies all fairness criteria simultaneously.

Nash Equilibrium

A set of strategies in game theory where no player can improve their outcome by unilaterally changing their choice.

Pareto Efficiency

An outcome where no individual can be made better off without making someone else worse off.

Grim Trigger Strategy

A strategy in a repeated Prisoner's Dilemma where a player cooperates until the partner defects, after which the player defects forever.

Code is Law

An ethos where smart contract outcomes are considered final and "legal" regardless of the author's original intent or the presence of bugs.

Sockpuppet attack

A situation where a single entity creates multiple anonymous identities to gain disproportionate influence in a decentralized system.

ZKRollups

A Layer 2 scaling solution that bundles transactions anonymously off-chain and distills them into a single transaction for Layer 1 verification.

Chit Funds

Traditional rotating savings and credit associations that served as a real-world inspiration for decentralized lending models.

Oracle

A trusted information source that provides external data to blockchain networks and smart contracts.

Condorcet's Jury Theorem

A theorem suggesting that if each individual has a probability p > 0.5 of being correct, the probability of a group reaching the correct decision approaches $1$ as the group size increases.

Transcendental Unifying Values (TUVs)

Integral, coherent ideals that provide stability to decentralized organizations by guiding behavior beyond rigid protocols.

Quadratic voting

A decision-making procedure where the cost of votes increases quadratically with the number of votes ($cost = n^2$), allowing minorities to express preference strength.

Conviction voting

A mechanism where voting power accumulates over time as participants maintain their tokens staked on a specific proposal.

Liquid democracy

A hybrid governance model where participants can vote directly or delegate their voting power to representatives on an issue-by-issue basis.

Futarchy

A governance model that uses prediction markets to determine which policies are most likely to achieve community-defined goals.
