A Research Perspective on Filecoin
The Filecoin network is launching in the middle of a revolution in internet architecture, where vulnerable centralized services dependent on trusted parties are being replaced with resilient decentralized solutions based on verifiable computation, and internet services are being relocated from inefficient central monoliths to the far reaches of the network by peer-to-peer markets.

"Two ears, one mouth": how to leverage bitswap chatter for faster transfers
As part of ResNetLab’s research endeavour to drive speed-ups on file transfers, Beyond Swapping Bits, we present a new contribution to IPFS Bitswap protocol. We argue that Bitswap is currently discarding a wealth of information that could be used to its benefit, improving retrieval success and minimizing the latency to retrieve content.

A brief history of (re)building the Internet
The Internet began life as a military network engineered for resilience in the face of a nuclear attack. That’s right—the same network you use to check on your friends and share cat photos has at its core a structural pattern intended to survive a nuclear exchange long enough to mutually assure destruction with the USSR.

Hello from the Decentralized Energy Project!
We’re two materials scientists here at Protocol Labs, and we’re working to improve the electricity grid. Why, you may be thinking, does a distributed file storage company have a project related to the energy grid?

SourceCred: an introduction to calculating cred and grain
You may not know that Protocol Labs is a supporter of an open-source governance and sustainability project called SourceCred. As a participant in a small SourceCred meetup last month, I learned enough about the underlying algorithm that I wrote up an explainer for their documentation repo and thought it might be interesting to share it here as well.
