BNB Attestation Service's Positioning and Significance

In 2025, BNB Chain introduced the BNB Attestation Service (BAS), aiming to address identity verification and reputation challenges in the blockchain space.

As the native verification and reputation layer on BNB Chain, BAS plays a crucial role in DeFi, RWA, and AI agent sectors.

As of 2025, BAS has become a key component of the BNB Chain ecosystem, with 197,152 holders and an active developer community. This article will delve into its technical architecture, market performance, and future potential.

Origin and Development History

Birth Background

BAS was created by BNB Chain in 2025 to solve the need for composable on-chain KYC, identity, and asset verification.

It emerged in the context of growing demand for reliable identity and reputation systems in blockchain, aiming to build verifiable Human Reputation Profiles to change the status quo.

BAS's launch brought new possibilities for RWA, DeFi, and AI agents in the blockchain space.

Important Milestones

• 2025: Mainnet launch, achieving composable on-chain KYC and identity verification.
• 2025: Adopted by the BNB Chain ecosystem, driving the price to reach $0.17051.

With support from the BNB Chain community, BAS continues to optimize its technology, security, and real-world applications.

How Does BNB Attestation Service Work?

Decentralized Control

BAS operates on a decentralized network of computers (nodes) spread across the globe, free from control by a single entity.

These nodes collaborate to verify transactions, ensuring system transparency and attack resistance, empowering users with greater autonomy and enhancing network resilience.

Blockchain Core

BAS's blockchain is a public, immutable digital ledger that records every transaction.

Transactions are grouped into blocks and linked through cryptographic hashes, forming a secure chain.

Anyone can view the records, establishing trust without intermediaries.

Ensuring Fairness

BAS adopts the BNB Chain consensus mechanism to validate transactions and prevent fraudulent behaviors like double-spending.

Participants maintain network security through running nodes or staking, and receive BAS tokens as rewards.

Secure Transactions

BAS uses public-private key encryption to protect transactions:

• Private keys (like secret passwords) are used to sign transactions
• Public keys (like account numbers) are used to verify ownership

This mechanism ensures fund security, keeping transactions pseudonymous.

BAS's unique feature is its ability to aggregate KYC data, asset proofs, on-chain behavior, social activity, and community contributions to build a comprehensive reputation profile.
