Using Bit Torrent for internal release management

We currently abuse our version control system and use it... pretty much as an FTP to store big release binaries (4+ GB). We are seeking to move away from this horrendous practice which has and continues to devolve and take more and more of IT's…

What logic is used to control Lock and Update actions in P2P networks? (similar to Bitcoin)

Bitcoin relies on Proof of Work (hashing) to control the writing to a central repository (the blockchain). It also relies on a set of rules for these updates, and defines what happens if a conflict is found (longest chain wins) Using that as an…

How does a pure P2P node connect to other nodes

I'm working on my first P2P app using C# core and gRPC and I'm finding it difficult to understand the concepts of how nodes find each other and build a routing table. For my design I'd like to only have nodes and no listener/directory/discovery…

How can I architect P2P discovery?

I've never really done network programming so this is all new to me. What I'm attempting to make is a Peer to Peer "chat" client. The idea is that anyone can connect to someone whose IP they know. All chat messages are to be distributed to…

How do I bootstrap a P2P service so that users can locate each other?

My P2P app needs to locate peers, but I don't want to hard-code a DNS address... One example I've seen is bootstrapping via IRC, but I'd like to do this over HTTP/s if possible. What are my options and techniques for bootstrapping a P2P app?

Is it possible to implement a robust 2 node P2P protocol?

I am thinking about how to implement a P2P protocol with only two nodes. At first I read about different DHT implementations in the hope that this scenario would be feasible. Turns out most intrinsically expect more than a few nodes to be…
