Privacy, Security, & the Future of On-Chain B2B Payments (Google Cloud & Aleo)

Let’s talk about something every enterprise finance leader thinks about: privacy and security. 

Now, on-chain transactions are transparent by default. That’s a feature, not a bug. But that can also create real concerns for enterprise teams. 

For a number of perfectly legitimate reasons, businesses may not want their payment history available on a public ledger. Whether it’s vendor payments, payroll, or internal transfers, companies need confidentiality as an option before they fully adopt digital asset payments.

At On-Chain B2B Payments Day, experts from Google Cloud and Aleo joined Bitwave for a deep dive into:

• Why privacy can be a major barrier to enterprise crypto adoption
• How businesses can protect sensitive payment data on-chain
• What’s next for security, compliance, and digital asset finance operations

And as a special bonus… 

They dropped some major news on our stage: Google Cloud and Aleo are teaming up with an official integration to build enterprise-ready privacy solutions for crypto payments.

Here’s what you need to know.

The Problem? Public Blockchains Are… Public

On-chain transactions are fully transparent. That’s great for accountability, but problematic for enterprise payments.

Here’s an example. If Google paid a vendor in USDC, competitors could track those transactions on-chain and extract competitive business insights. So, while there are several fantastic reasons to move payments on-chain, businesses require a certain degree of payment confidentiality. 

And it’s not just businesses. 

Consumers demand confidential payments, too. Not everybody wants their Venmo history visible to the world. (But, that’s exactly how crypto payments work today.)

And that doesn’t even mention regulatory controls. Businesses need to share data selectively. They need to prove compliance without revealing sensitive financial details to the public.

That’s why privacy-preserving payments are the next big unlock. 

Enter: Aleo and Provable

The Big Announcement: Google Cloud x Aleo Integration

Live on the Bitwave stage – Google Cloud and Aleo announced a strategic partnership to bring confidential payments and zero-knowledge proofs (ZKPs) to enterprise finance!

Here are the key details: 

• Google Cloud will run an Aleo validator to boost network security & scalability.
• Aleo blockchain data is now live on Google Cloud’s Web3 portal. And the best part? The datasets are available right now for developers. (Free!)
• Together, they’re collaborating on ZK-powered private payment solutions to help enterprises adopt stablecoin payments securely.

This is a huge step toward enterprise-ready blockchain payments. Google Cloud and Aleo are balancing privacy, compliance, and transparency.

Zero-Knowledge Proofs: Delivering Crypto Privacy in Crypto

So, how does on-chain privacy actually work?

Zero-Knowledge Proofs (ZKPs) allow you to prove something is true without revealing any details.

For example, instead of exposing your entire bank balance to prove you have $10,000, a ZKP lets you simply prove, “I have more than $10,000.” All without revealing the exact number.

This solves a critical transparency problem for enterprise adoption of on-chain payments:

• Vendors can accept payments without exposing revenue data
• Payroll can be processed without employees seeing each other’s salaries
• Enterprises can comply with regulations without over-sharing financial info

In the same way HTTPS encrypted the internet, ZKPs will encrypt crypto transactions, while still enabling the benefits of blockchain.

Security & Compliance Matter

But privacy alone isn’t enough. Businesses need security and regulatory clarity.

• Custody is critical: Enterprises can’t just spin up a wallet and start transacting in crypto. A serious payments strategy requires an enterprise-grade custodian.
• Regulatory compliance is evolving: – Stablecoin payments are growing fast, but regulatory clarity is still catching up. Businesses need solutions that ensure tax reporting, AML compliance, and audit readiness.
• On-Chain Ops Must Mirror Traditional Finance: Today, wire transfers and ACH payments include metadata for tracking and reconciliation. On-chain payments need to incorporate similar standards for enterprise adoption.

The good news? The tech stack is maturing fast, and companies like Bitwave, Google Cloud, and Aleo are leading the charge.

Key Predictions for 2025

To wrap up, here are the biggest predictions made on stage: 

1. Confidential stablecoin payments will become the standard. Just like HTTPS transformed the internet, private smart contracts will secure on-chain business transactions.
2. Smart contract automation will replace outdated finance processes. Invoicing, payroll, and vendor payments will move from manual processes to programmatic, on-chain execution.
3. Traditional finance will have to adapt—or be left behind. Banks, payment processors, and legacy SaaS finance tools will need to integrate on-chain payments or risk losing business to more efficient blockchain solutions.

The bottom line? On-chain B2B payments are going to completely change the way businesses transact. They’re faster, cheaper, and programmable than traditional payment rails. 

And with privacy solutions like ZKPs, they’re finally enterprise-ready.
