To achieve a trustworthy distribution of software, both the binary publisher (e.g., a software developer or company) and the end users play critical roles. Here's a step-by-step breakdown of how this process works, focusing first on the publisher's responsibilities and then on what end users must do to verify the software in a safe manner.

Steps for the Binary Publisher

1. Compile the Source Code: Compile the source code into a binary or build. This should be done in a clean, controlled environment to ensure that the build is reproducible and hasn't been tampered with.

2. Generate a SHA-512 Hash: Use a tool to calculate the SHA-512 hash of the compiled binary. This hash serves as a unique fingerprint of the binary.

3. Sign the Hash: Digitally sign the SHA-512 hash using a private key. The digital signature ensures that the hash hasn't been altered and verifies the identity of the signer.

RFC: Enhanced Collective Contributions

Introduction

This RFC proposes an enhancement to the Referenda Pallet of the Polkadot network to introduce a feature for collective contributions towards decision deposits of referenda. This proposal aims to increase participatory governance by enabling stakeholders to collaboratively fund referenda deposits. A key aspect of this proposal is the inclusion of a configurable feature flag within the pallet, allowing for network-specific activation of this functionality.
