A decentralized marketplace for zero-knowledge proofs. Apps and chains request a proof, independent provers generate it off-chain, and the chain only has to check the small proof instead of redoing all the heavy work. ZKC is its native token.

What is Proof of Verifiable Work?

It is how provers get paid on Boundless. Instead of burning energy on a race like Bitcoin mining, provers earn ZKC only for real proofs that clients actually use, scored by volume, speed, and how complex the job was.

Where did Boundless come from?

It was incubated by RISC Zero, the team behind a general-purpose zero-knowledge virtual machine, then spun out as its own decentralized protocol. So it is a spin-out of RISC Zero, not a fork of another coin.

Does ZKC have a supply cap?

No. It launched with 1 billion ZKC and keeps minting new tokens, about 7% in year one and tapering toward 3% by year eight. Those tokens reward and secure provers, so the supply is uncapped, unlike Bitcoin's fixed 21 million.

ZKC launched in late 2025 and was listed on Binance, with an airdrop of 15 million tokens around launch, and it trades on other major exchanges too. It is a new token and moves a lot, so only try a small amount. (Information only, not an exchange or investment recommendation.)

Boundless ZKC

the tireless proof-smith of every chain

🎭 part blacksmith, part bookkeeper: forges heavy math into tiny proofs, and bills only for honest work

🌱 PoS🌉 Bridge📜 Smart Contract

💬 “Hand me the heavy computation. I will hammer it into a proof small enough for any chain to check in a blink, and I only ask to be paid when the work was honest and useful. That is the whole craft.”

💬 TL;DR

The job: a marketplace for zero-knowledge proofs. Apps ask for a proof, independent provers make it off-chain.
The trick: a chain checks one tiny proof instead of re-running the heavy work on every node.
Pay: provers earn ZKC through Proof of Verifiable Work, only for proofs people actually use.
Roots: built on RISC Zero's zkVM and spun out as its own protocol. Mainnet went live on Base in September 2025.

📖 The Story

Every blockchain has the same tired habit: when something needs checking, every single computer in the network does the whole job again. It is safe, but it is slow and wasteful, like a town where a hundred clerks each re-add the same bill by hand. Boundless was built to break that habit.

The idea grew inside RISC Zero, a team that had built a general-purpose zero-knowledge virtual machine, a kind of computer that can run ordinary code and then hand you a short mathematical receipt proving it ran correctly. Co-founder Jeremy Bruestle and his crew realized this receipt could be sold as a service. In 2025 the project spun out as its own decentralized protocol, with Shiv Shankar stepping in as Boundless CEO around May, backed by reported funding near $52–54M led by Blockchain Capital and Bain Capital Crypto.

The plan came together fast. Prover incentives went live in July 2025, the ZKC token claim opened around August 25, and on September 15, 2025 mainnet launched on Base, an Ethereum Layer 2. Binance listed ZKC with a 15-million-token airdrop. Suddenly the proof-smith had a shop, customers, and a queue of work.

Today the craft is simple to say and hard to do: take the heaviest computation a chain can throw at it, and forge it down into a proof tiny enough to verify in a blink. No drama, no mascot. Just a steady hammer.

💎Scarcity No cap, inflationary

🧩 How it works

Think of it as a workshop with two doors. Through one door, a developer walks in and requests a proof for some heavy task. Through the other, independent provers pick up the order, do the math off-chain, and deliver a small proof. To take an order, a prover must stake ZKC as collateral, so cutting corners costs them. Pay only flows for proofs a client genuinely uses, that rule is called Proof of Verifiable Work.

🧑‍💻 Requestors post an order → 🏪 the market matches it → 🔨 a prover stakes ZKC and forges the proof → ✅ the chain checks the tiny result, and 💰 Proof of Verifiable Work pays the prover only for a proof that was used.

🌗 Light & Shadow

🌕 Light

Solves a real bottleneck, off-loading heavy work so chains can scale without making every node redo it
Built on RISC Zero's general-purpose zkVM, so it can prove arbitrary code, not just one narrow task
Pay is tied to useful work. Proof of Verifiable Work rewards real proofs by volume, speed and complexity, not energy burned in a race

🌑 Shadow

Very young. Mainnet only launched in September 2025, so its long-term demand is unproven
No supply cap. ZKC keeps inflating (about 7% in year one, easing toward 3% by year eight), which can dilute holders if usage lags
Crowded field. Other ZK proving networks are chasing the same job, and provers face real costs and slashing risk if they stake and underdeliver

🧬 Evolution lineage

Boundless is not a fork of any coin. It is a spin-out of RISC Zero: the same team's zero-knowledge virtual machine, productized into a standalone protocol with its own token. Its closest cousins are other ZK proving networks like Succinct and Lagrange, same craft, different workshops.
