Every chain aspires to be the hub for real users. Every ecosystem claims to be building the “onchain economy.” However, without a system for reputation, all chains begin to resemble one another—battlegrounds for mercenary capital, Sybil farming, and farm-and-dump cycles. It’s a pattern the space has seen repeatedly over the past decade.
Base is different. With a focus on real-world adoption from Day 1, Base has inspired builders to solve the problems of modern society through blockchains, cryptography and AI rather than boxing themselves in a “crypto-only” paradigm.
Zeru recognizes the importance of this. In launching the universal reputation primitive, the mission is to solve real problems such as undercollateralized loans, credit-backed money markets, employment verification, and societal reputation rather than restricting to a “crypto-only” paradigm that has led to earlier attempts over the last 10 years being largely unsuccessful.
With zScore now live, Base introduces reputation-as-a-service—empowering apps to differentiate between real users and extractive actors. It also allows users to build a verifiable, omnichain reputation that can move across ecosystems and into the modern society that we live in.
zScore brings a new layer of verifiability to Base. Apps can now assess users based on onchain behavior; not just on Base, but also across Ethereum, Arbitrum, Optimism, and other networks.
This reputation is portable, so users aren’t forced to start from zero when exploring new ecosystems. They can bring their existing onchain activity and reputation with them to Base.
zScore also integrates zkTLS via Reclaim Protocol, allowing users to prove offchain credentials—like credit scores, Uber ratings, professional track record or residency—onchain, without giving up privacy or undergoing KYC. This unlocks new possibilities for lending, consumer credit, NFT whitelists, employment verification and more—now made possible through reputation on Base.
With zScore, Base becomes a network where real users are recognized, loyalty can be built, and new models of credit and value creation can emerge.
While other chains focus on transactions, Base is developing an ecosystem that includes identity, trust, and reputation.
zScore makes Base a network where reputation plays a foundational role.

The Airdrop Efficiency Crisis
How Behavior-Based Distribution Can Save Billions in Wasted Token Value

The Airdrop Game is Changing. Is Your Wallet Ready?
If you've been farming airdrops the same way for the past few years, you need to read this.

zPass: Your Passport to Onchain Privileges
Building and growing blockchain-based apps is entering a new phase where behavior matters more than balance, and where users can unlock rewards, yields, and access based on how they act onchain. This shift has a name: reputation. And now, there is finally a way for everyday users to quantify and use that reputation across the entire ecosystem.
