Here is a brief summary of Sia and its history with the Blake2b hashing algorithm.

🤖 What Sia Does

Sia is a decentralized cloud storage platform that uses blockchain technology to create a marketplace for data storage . You can think of it as a peer-to-peer alternative to services like Amazon S3 or Google Cloud, where users rent out their unused hard drive space to others and earn Siacoin (SC) in return .

How it works:

  • Your files are encrypted on your own device before they are uploaded .
  • The encrypted data is split into many pieces using erasure coding and distributed across multiple independent storage providers around the world .
  • This ensures no single provider can read your files, and your data remains available even if some providers go offline .
  • Storage contracts and payments are enforced by the Sia blockchain, which uses a Proof-of-Work consensus mechanism .

📜 Brief History of the Blake2b Fork

The history of Sia's adoption of the Blake2b hash function for its Proof-of-Work is a story of community defense against ASIC monopolization .

  • The ASIC Arms Race: The Sia network initially used the Blake2b hashing algorithm . In 2017, the Sia team announced Obelisk, a community-funded project to create ASIC miners specifically for the network .
  • External Threats: Before Obelisk could deliver, Bitmain and Innosilicon secretly developed and released their own more powerful Sia ASIC miners, threatening to dominate the network's hashrate and undermine the community's investment .
  • The Fork Decision: To protect the network from this centralization, the Sia core developers decided to reset the Proof-of-Work algorithm in a hard fork on October 31, 2018 . This software upgrade effectively "bricked" the Bitmain and Innosilicon machines, making them obsolete on the Sia network, while allowing the new Obelisk miners to continue operating . The hard fork was controversial but was seen as a necessary step to maintain the network's decentralization and protect the community's interests .
