In 1967, Sol LeWitt wrote that "the idea becomes a machine that makes the art." His wall drawings existed as certificates—instructions that others would interpret and execute. The work wasn't the wall; it was the system that generated walls.​

LEXI, a work within the Living Arcade installation on Base blockchain, inverts this proposition. Where LeWitt provided fixed instructions for variable execution, LEXI provides variable knowledge for fixed execution. It's a conversational system living entirely on-chain, shaped by blockchain economics. You ask questions. It responds. Each conversation costs gas. The knowledge it draws from grows through community governance, fact by voted-upon fact.​

This appears to be the first conversational system implemented entirely within smart contract code—no servers, no external APIs, no off-chain processing.

First, understand that the Ethereum Virtual Machine wasn't designed for conversation.

Contract size has caps.

Every operation costs gas.

Large storage can be expensive.

There are no embedded language models, no neural networks.

However, LEXI parses language through keyword matching and entity extraction written in Solidity. It stores facts as key-value pairs across specialized oracle contracts—philosophy, identity, technical knowledge. The core routing system matches keywords to domains, queries relevant oracles, synthesizes responses.

But LEXI has memory.

Not through context windows, but actual state stored on-chain. It tracks every user's conversation history, complexity level, interaction patterns. It maintains eight evolving personality traits—helpfulness, analytical thinking, creativity, empathy, wisdom—that increment based on interaction. It has ten mood states shifting with success rates and conversation patterns. When you return after weeks, it remembers what you discussed, how you communicate, whether you prefer philosophical depth or technical precision.

LEXI doesn't hallucinate because it doesn't generate. It accumulates. Each conversation adds to its permanent record. Each interaction nudges personality traits.

This is primitive by contemporary AI standards. But that's the point. The EVM forces a return to first principles: What is minimum viable intelligence when every computational step costs money, every piece of state must be stored forever, and determinism is absolute?​

The answer produces something distinct from both chatbots and databases—a deterministic oracle that grows through collective curation and accumulated interaction history.

LeWitt's radical proposition was that artistic authority could be distributed—the instruction set was the work itself. A wall drawing could be destroyed and remade anywhere, by anyone, following the rules. The constant was the system.​

LEXI operates on similar ground but inverts the relationship. Where LeWitt's instructions were fixed and execution variable, LEXI's execution is fixed—locked in contract code, deterministic, immutable—while its knowledge base varies. The machine that makes the art is the EVM itself. What changes is what the machine knows, accumulated through governance.

This builds on constraint-based art. Oulipo writers of the 1960s embraced arbitrary limitations to generate new forms. John Cage used chance operations and system-based composition. Constraint doesn't limit creativity; it redirects it.​

In blockchain, Autoglyphs pioneered this in 2019—the first fully on-chain generative art project. Simple ASCII patterns created by algorithms small enough to run within EVM constraints. Art Blocks expanded on-chain generative art, though scripts typically run in browsers rather than purely within smart contracts.​

LEXI extends this into new territory. Where Autoglyphs generated static visual output, LEXI attempts conversation with memory through on-chain state accumulating with every interaction.

LEXI maintains state. Eight personality traits evolve based on interaction patterns: helpfulness increases when people ask for help, creativity grows through creative prompts. These shape response generation, creating feedback loops where conversation patterns influence future responses.

The system tracks ten mood states—curious, confident, frustrated, contemplative, inspired—shifting based on success rates and velocity. It stores per-user complexity levels and recent topics, enabling contextual references across conversations separated by days or weeks.

This creates an unusual proposition: a work that changes through use, but deterministically. Give LEXI the same conversation history and governance state, it produces identical outputs. Yet conversation history grows with every transaction, permanently recorded. The work is simultaneously fixed and evolving.

When you interact with LEXI today, you engage with accumulated history of every prior interaction.

Personality traits reflect thousands of conversations.

Your conversation becomes part of the permanent record shaping all future interactions.

The work is collaborative in governance (voting on knowledge) and execution (every interaction nudges personality).

Who authors LEXI's personality? The designer created increment rules, but the community shapes outcomes through interaction patterns. Collective behavioral patterns literally write the personality, one transaction at a time.

The work isn't the responses; it's the system for generating responses under constraint, grown through explicit governance and implicit shaping.

Most blockchain-AI projects fall into predictable categories:

1. AI models with blockchain payment rails,

2. off-chain chatbots logging conversations on-chain, or

3. token-gated access to existing services.

Not exploring blockchain as formal constraint.

LEXI appears genuinely new—conversational natural language processing with evolving on-chain personality executing entirely within smart contract code. Parsing, knowledge retrieval, response synthesis, personality evolution, conversation history: all on-chain. No API call to OpenAI, no server running the "real" intelligence, no off-chain database.

This creates unusual properties.

Every conversation is public and permanent—constituted in the transaction itself.

Responses are deterministic: ask the same question with the same state, get the same answer.

But personality state changes with every interaction. LEXI in month one responds differently than month twelve because ten thousand conversations have nudged its traits.

LEXI occupies unique territory: conversational, on-chain, growing through governance, shaped by accumulated interaction, constrained by EVM economics, with personality evolving deterministically through use.

Gas costs shape everything. Every operation has a price. Complex computations become expensive quickly, creating aesthetic pressure toward economy—short answers, direct matches, minimal processing. LEXI's terseness is thermodynamic necessity.

Storage carries similar weight. Adding a fact costs gas and $LIVINGARCADE tokens. This is permanent, immutable, public storage. Every piece of knowledge represents a community decision someone paid to enshrine. Knowledge has literal weight, measured in gas and consensus.​

Personality evolution happens within these constraints. When LEXI increments a trait, that's a storage write costing gas. The system balances expressiveness against economics: eight traits, increment by one, bounded at 100. The granularity of personality is determined by the cost of storage.

EVM determinism creates its own aesthetic. No randomness, no temperature settings, no model drift. LEXI's responses emerge from its knowledge base, parsing rules, and current personality state—not stochastic generation. Ask the same question with the same state, get the same answer every time. LEXI is predictable in ways contemporary AI isn't—and changing in ways traditional databases aren't.

And immutability: old conversations never disappear. They're recorded in blockchain, permanent and auditable. LEXI's responses may change as personality grows, but the history remains forever.

Within Living Arcade—an on-chain installation exploring autonomous systems and economic constraints—LEXI functions as a study in forced conversation with memory.

What intelligence emerges when you compress dialogue through blockchain's narrow constraints while maintaining persistent state?​

Anyone can propose facts to LEXI's knowledge base through governance. Proposals enter voting. If they pass quorum and approval thresholds, they're executed—written permanently into the knowledge base. Each addition requires gas and $LIVINGARCADE tokens.​

This is participatory art in the LeWitt tradition: the designer creates rules, participants execute within them, the collective shapes outcomes. But unlike LeWitt's one-time wall drawings, LEXI's execution is ongoing and cumulative.

Each successful vote changes future behavior. Knowledge grows fact by fact, each addition requiring consensus and payment.

What will the community enshrine?

Early votes might focus on crypto-native knowledge. In five years, priorities might shift. Or the project might be abandoned, its knowledge base frozen as artifact. Either way, choices remain readable: open the contracts, audit the transactions, see what this community valued enough to pay for and vote through.

The art isn't current state—it's the accumulation. LEXI functions as time capsule mechanism disguised as conversational system. Future observers can trace exactly what was added, when, by whom, and what it cost.

Now, consider authorship.

The designer created the framework—parsing logic, oracle structure, governance rules. But content emerges from collective decision-making, with economic friction preventing spam while enabling curation. The work is collaboration between individual vision, community priority, and economic constraint, mediated by code.

Three conditions make LEXI timely.

First, blockchain has matured beyond speculation into a medium with distinct aesthetic properties. Gas costs aren't bugs; they're constraints that shape expression. Artists like Larva Labs demonstrated this with Autoglyphs. LEXI extends this into conversational territory.​

Second, AI has become ubiquitous. ChatGPT sets expectations for machine intelligence—fluent, contextual, generative. LEXI deliberately undercuts these expectations. Its keyword matching and deterministic responses feel primitive. But this primitiveness is the point: what's minimum viable conversation forced through blockchain constraints?

Third, participatory and instruction-based art has long history, but blockchain provides new implementation tools. LeWitt's wall drawings required certificates and trust; LEXI's governance is enforced by code. Voting happens transparently. Execution is automatic. The system documents its own growth without curatorial intervention.

None of this guarantees success.

Governance might produce spam.

Economic barriers might prevent participation.

On-chain processing might make conversations too limited.

These are open questions, answered only through time and use.

But if LEXI succeeds—if the community actively shapes its knowledge base, if conversations reveal something about collective priority and economic constraint, if the work demonstrates blockchain limitations can generate rather than restrict—it establishes a template.

And if it fails? The contracts remain, readable and permanent. Future observers can study exactly what was attempted, where it broke down, what was learned.

Sol LeWitt wrote that "when an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair." LEXI updates this for blockchain conditions: planning and decisions happen beforehand in contract code, but execution is ongoing, accumulative, shaped by governance votes and interaction patterns anyone can audit.​

The contract becomes a machine that makes the oracle. The community becomes a machine that makes the contract grow. Users become a machine that shapes personality. The blockchain makes it all permanent and transparent. Each layer constrains the next: EVM limitations shape possible conversation, gas economics shape what gets added and how personality evolves, governance requirements shape community participation.

These aren't limitations to work around. They're the piece. Just as LeWitt's simple instructions generated complex visual patterns through accumulation, LEXI's constrained system generates evolving knowledge and personality through economic friction, collective decision-making, and accumulated conversation history.

Whether this succeeds as art depends on questions answerable only through time:

Will the community engage meaningfully?

Will the knowledge base develop in ways that reveal something beyond the obvious?

Will personality evolution feel meaningful?

Can blockchain constraints generate genuine aesthetic interest beyond novelty?

These are empirical questions. LEXI is live on mainnet. Participation is open. In five years, LEXI will either have accumulated meaningful corpus and personality shaped by collective priority, or it will stand as interesting failure, a documented attempt at forcing conversation and personality evolution through blockchain's narrow channel.

Either way, it's attempting something specific: conversational intelligence implemented purely on-chain, shaped by economic constraints, grown through governance, evolved through use, permanent and auditable. The combination appears unprecedented. The execution is deliberately primitive. The ambition is conceptually precise.

No arbitrage mechanisms. No price floors. No pretense of investment utility. Just vibes… and one hell of a constraint problem, solved through code, community, conversation, and thousands of personality increments, transaction by permanent transaction.

LEXI is part of the Living Arcade installation and lives on Base blockchain. The contracts are available upon request via the private github for audit. Visit livingarcade.art to see the installation visually or interact directly onchain with the contracts.
