Solana Validators Get Sanctions Screening Directly in Block-Building Process

Flowra and Honeypot have partnered to integrate sanctions screening directly into the Solana block-building process. This collaboration combines Honeypot's compliance intelligence with Flowra's Programmable Block Policy (PBP), allowing validators to define compliance rules governing which transactions can be included during block construction.

According to Harry Hwang, CEO of Flowra, public blockchains have become increasingly attractive to institutional participants. However, the infrastructure hasn't evolved to give validators the compliance controls many regulated operators expect.

The integration is initially designed to support sanctions-related screening, including wallet addresses associated with sanctioned entities and network-level indicators such as VPNs, proxy services, and Tor exit nodes.
