Ever feel like it's hard to keep up with technical developments in crypto? People ferociously @ each other on X, opining on infinitesimal details, while you just want to properly understand of the issue at hand? (er, rollup wars, hello) Iām starting a content series aimed at the intermediate audience ā š - not pure beginner and not advanced yoda āš¶š„· Explain Again! is where no question is too stupid - as youāll see from my stupid questions š On some episodes I interrogate expert friends, stubbornly digging until we get the fundamentals straight. On other episodes weāll use visual explainers to grok complex dynamics.

We're kicking off Explain Again! with Session, the Signal-like chat app that is web3-native and privacy-first. They're pushing boundaries with their approach to privacy and distributed tech, complemented by a beautiful UI and smooth UX. I'm curious what tradeoffs they made and what the implications are for users. https://www.youtube.com/watch?v=bgIitv3Dmkk

Sneak peek of the Session whitepaper walkthrough: š Metadata Leakage: More Dangerous Than You Think Even if message content is encrypted, knowing who is talking to whom, when, and how often can expose activists, dissidents, and high-value targets. Session mitigates this by removing centralized servers from the equation and using onion routingābut with some key differences from Tor. š āLike Tor, But Double Torā Instead of a single onion route from sender to recipient, Session uses two separate onion circuitsāone for sending and another for retrieving messages. This prevents a single node from learning both ends of the conversation.

ā³ Messages Expire if Not Received Unlike traditional messaging apps, messages in Session are not stored indefinitely. If a recipient doesnāt retrieve a message in time, itās permanently lostāan interesting trade-off between privacy and usability. š° The Tokenomics of Attacks Running a node requires staking tokens, creating a financial cost for Sybil attacks. But could attackers drive up token prices, making it prohibitively expensive for honest users to participate? The economic incentives remain an open question. š§ How Many Layers Should an Onion Have? More hops in an onion route donāt always mean better securityātiming correlation attacks can still deanonymize users. Session sticks with the classic three-hop model, striking a balance between privacy and efficiency.
