Primus and the Difference Between a Visible Payment and a Public Salary A public blockchain can make it easy to confirm that a payment happened. But payroll raises a different concern: salary information should not be public. Employers need auditable records without exposing individual compensation. This tension was put to a practical test through Primus's @primus_labs collaboration with AllScale on Private Payroll, a stablecoin payroll workflow tested on BNB Chain. Going deeper into that 👇 The Business Problem Behind Onchain Payroll When a company pays staff through ordinary onchain transfers, the transaction amount is public alongside wallet addresses, timestamps and transaction hashes. Repeated payments can reveal salary patterns, differences in compensation and bonus activity. Businesses need to reconcile payments, while employees need control over who can see their pay details. What Primus Contributes AllScale provides the payroll application and payment workflow. Primus supplies FHETransform, its privacy layer based on Fully Homomorphic Encryption (FHE). FHE allows supported operations to be carried out on encrypted values without first revealing the original numbers. In this payroll design, the salary amount is encrypted before it is submitted to the smart contract. The chain can record the settlement while the amount itself is not published in plaintext. This does not make the entire transaction invisible. The company wallet, employee receiving addresses, timestamps, transaction count and transaction hashes remain observable. How the Payroll Process Works First, the employer prepares a payroll batch through AllScale. The employer retains its self-custodial wallet and authorizes payment. Next, Primus's FHETransform encrypts each salary amount before it reaches the smart contract. The payment is then recorded on BNB Chain without exposing its amount in readable form. After settlement, an employee can sign a message with their own wallet to access their authorized salary information. No onchain transaction or gas fee is required just to view the details. AllScale manages batch preparation, payouts and reconciliation. Primus protects the salary values. What the Initial Test Demonstrated On September 1, 2026, the two teams completed an initial technical validation involving four fictional employees and sample salary amounts. All four payments were recorded on BNB Chain. The decrypted salary figures and balances matched the original test payroll file. Payroll preparation, encrypted amounts, settlement records and employee-authorized viewing were tested together. The Important Boundaries The test did not hide every detail. Observers could still identify the company wallet, recipient addresses, payment times and transaction hashes. Encryption of salary amounts does not conceal the relationships between wallets or prove that a receiving address belongs to a particular employee. Nor does a blockchain record establish that the salary was calculated correctly or that tax and employment obligations were met. The initial test used only four sample payments. Authorization controls, exception handling and integration with existing payroll systems still require further testing before production readiness can be assessed. The significance is the design choice. Primus and AllScale are exploring how businesses can retain useful settlement records without turning employee compensation into public information. It is a practical example of privacy being applied to a specific financial requirement, rather than treating confidentiality as an all-or-nothing feature. @primus_labs
