⚖️ Decentralization is a legal tactic used alongside activism
⌛ Decentralizing the wrong things is a waste of time
☠️ Decentralizing everything is suicide by bad UX

Thread! 👇

Decentralization should shadow the law it is trying to avoid. Chronology of popular p2p file sharing apps:

1999: Napster
2002: Kazaa
2005: BitTorrent

Each app degraded its UX and altered its protocol for better legal protection.

Decentralization for legal protection at the expense of UX:

• Napster used p2p to avoid central hosting
• Kazaa decentralized file search, hurting results and quality control
• BitTorrent left search to others (The Pirate Bay). Terrible onboarding but better legal positioning

Decentralize your tech until activists can takeover:

• The Pirate Bay founders have gone to the ends of the earth to keep it online
• Tor depends on activist exit node operators

Activists *will* come! Coppersurfer runs a Tor relay, Bitcoin node, and a BitTorrent tracker!

What should we decentralize? Look for hacks you can formalize:

• Link-only mp3 sites → Napster skirting hosting
• User hosted Napster servers → eDonkey architecture
• Coin tumblers → privacy coins
• "No logs" VPNs → Tor
• Anonymous domain purchasing → hidden services

Tech vs. law starts w/ decentralized protocols, but is continued by activists, businesses, and OSS

• Pirate Bay was stronger w/ Sweden's copyright law
• Their servers are "raid-proof"
• Pirate Bay proxy sites help w/ ISP bans
• Protocols evolve via OSS communities

Recipe for a successful decentralized protocol:

• Enable a valuable, legally suppressed use case
• Company's products avoid sensitive use case. Let 3rd parties do that
• Tech should be useful outside sensitive use case

BitTorrent checked these boxes. @AugurProject might too!

Decentralize to stay alive, users don't want more.

Open sourcing your decentralized protocol can provide legal insulation. There were dozens of OSS BitTorrent clients, what good does killing the company do?

Decentralization is part of a larger legal playbook. More doesn't always help: BitTorrent was less decentralized than Kazaa but more legally resilient.

Their use of OSS, marketing, PR, and implicit reliance on 3rd parties (The Pirate Bay) mattered more

BitTorrent won the legal war by being thorough:

• Website talked about hosting not downloading
• @bramcohen only talked about legal uses. Claimed no profit motive
• Prominent free speech defense on website
• Redundancy via OSS clients
• Outsourced liability to Pirate Bay

Decentralized protocols don't absolve the company of responsibility, it just shifts to the client:

• Limewire had a copyright filter, disabled by default. Court reaction: "What? Make it mandatory!"
• Kazaa had a NSFW filter. Court reaction: "So you could filter copyright too!"

Passing the buck to activists buys room to decentralize. While Hollywood fought Pirate Bay, the BitTorrent community added

• Multitracker support (takedown resilience)
• DHTs (decentralized torrent metadata storage)
• PEX (peer discovery w/o trackers)

Helping The Pirate Bay!

Some look at the file sharing movement and say "BitTorrent didn't win, Netflix+Spotify did!"

Decentralization exploits legal boundaries, exposing rent seeking in anti-competitive industries. BitTorrent created the conditions that allowed Netflix and Spotify to exist

We all won!

The political framing for decentralization is "censorship resistance." The market framing is "anti-competitive market resistance."

P2P file sharing corrected anti-consumer markets for music and movies. Imagine what we can unlock with Bitcoin and Ethereum!

The chronology of the "most popular file sharing app" is roughly:

Napster
Limewire
Kazaa
eDonkey
BitTorrent

Reflecting "minimum viable decentralization" over time. Limewire was early, Kazaa more usable. BitTorrent's UX was bad, but won legal long game medium.com/@jbackus/minim…

When decentralizing, half measures bite you in the ass:

🙈 Aimster obscured searches and user IPs from its protocol
💪 BitTorrent disowned search and left IPs in the clear

Courts argued Aimster's conduct was "willful blindness." BitTorrent's choices made its position stronger

Boiling down decentralization movements, we build technology to resist governments installing filters:

💿 Copyright (BitTorrent)
💰 Anti-money laundering (Bitcoin)
💌 Content/communication (Tor)

Legal battles and tech evolution continues until its too hard to install a filter

Once legal pushback enters a decentralized product space, evolutionary pressures start filtering:

• Weaker willed torrent search engines closed
• BitTorrent's protocol evolved
• The Pirate Bay doubles down

Expect same when the US government takes on real crypto companies!

Decentralized technologies mixes legal and objectionable streams together:

• Can't separate darknet market traffic from anti-censorship on Tor
• BitTorrent protocol is unaware of content

You can't throw out the bath water without throwing out the baby, by design.

In a decentralized product market, recklessness buys early growth. Many companies grew by marketing to pirates.

I call BitTorrent an "ugly duckling." It didn't seem like a winner until late in the game.

Here's how to spot ugly duck investments: medium.com/@jbackus/inves…

What parts of our tech should we decentralize? How do we know when we're done?

I think a lot of people in crypto are struggling with these questions. I think history provides an answer. Find your "minimum viable decentralization" medium.com/@jbackus/minim…

This thread focused on decentralization as a legal tactic to be used sparingly, pulling from the history of p2p file sharing.
