Solana infrastructure company Helius has acquired Light Protocol, a developer of Zero-knowledge privacy technology on Solana, as the blockchain industry increases investment in privacy-focused infrastructure.
The acquisition brings Light Protocol’s engineering team into Helius and marks a return to the startup’s original focus on blockchain privacy after spending the past two years developing ZK Compression, a data-compression framework designed to reduce Solana state storage costs.
Light Protocol said the acquisition would allow the team to return to its original focus on privacy infrastructure while continuing to maintain the ZK Compression protocol and related developer tools.We’re joining @helius to build the most used privacy protocol in crypto.
Helius is the leading infrastructure company on Solana, and having worked together closely in the past 2 years, we know them to be an elite team with the distribution power to make privacy go mainstream.… https://t.co/PVzj4trLgNpic.twitter.com/pfi2txesDw

Founded in 2021, Light Protocol initially focused on bringing privacy-preserving technology to Solana through zero-knowledge cryptography. The company later shifted its attention toward scalability infrastructure, co-developing ZK Compression with Helius and launching the framework in 2024.
According to the companies, future development efforts will focus on building a privacy layer for Solana that supports confidential payments, encrypted balances, and privacy-enabled decentralized finance applications. The acquisition does not affect existing ZK Compression users, and the protocol will continue to be maintained.
Beyond ZK Compression, Light Protocol contributed several cryptographic primitives that expanded Solana’s ability to support zero-knowledge applications.
Among the technologies credited to the team are:
These additions enabled developers to build more advanced cryptographic applications directly on Solana’s runtime. Light Protocol later applied similar cryptographic techniques to create ZK Compression, which uses zero-knowledge proofs to significantly reduce the amount of state data that applications must store on-chain.
For Helius, the deal expands its role beyond infrastructure services such as APIs, validator support, and developer tools. The company is increasingly positioning itself around protocol-level infrastructure, including privacy technology that could support institutional blockchain applications.
Privacy remains one of the major challenges for public blockchains because transaction and account activity are typically visible to anyone on the network. While scalability improvements have reduced costs and increased throughput, many enterprises continue to require confidentiality for financial operations. Industry participants have increasingly explored privacy solutions that preserve compliance requirements while limiting public exposure of transaction data.
The acquisition comes amid renewed interest in privacy technologies across the digital asset sector. Alongside ongoing web3 fundraising updates, investors and infrastructure providers have continued allocating capital toward privacy-enhancing technologies, reflecting growing demand for secure blockchain applications across institutional and decentralized markets.
Recent developments include:
The deal also reflects a broader consolidation trend within crypto infrastructure, where larger companies are acquiring specialist teams with cryptography expertise rather than developing those capabilities internally.
As blockchain adoption expands into payments, tokenization, and financial services, privacy infrastructure is increasingly being viewed as a requirement rather than an optional feature.
