The Tor Project

What is congestion control? Instead of using a fixed speed limit, congestion control lets Tor adapt how much data moves through a circuit based on available capacity. For users, the goal is simple: improved speed and lower latency. blog.torproject.org/congestion-con…

What is Counter Galois Onion? A new encryption design for Tor circuit traffic. The main goal: stronger protection against tagging attacks, where an attacker tries to modify traffic in one place and recognize the change somewhere else on the network. blog.torproject.org/introducing-cg…

🚨🔃 Arti 2.5.0 is out. This release marks Counter Galois Onion as stable, enables Congestion Control by default for improved speed, and includes fixes for two medium-severity DoS security issues. Read the full changelog: blog.torproject.org/arti_2_5_0_rel…

@roxananasoi thank you for adding Tor VPN beta. :)

New addition to VPNscorecard: The @torproject VPN 👉 vpnscorecard.com/vpn/tor-vpn Protocol: Tor onion routing (3-hop circuits) via Arti, Tor's Rust implementation; per-app circuit isolation and pluggable transports for censorship circumvention. ⚠️ Notes: Experimental stage.

Huge thanks to everyone who supported us during the internet freedom quadratic funding campaign! Your support means a great deal to us 🙏❤️🐙 Special thanks to @torproject and @FundingCommons for organizing the campaign, to @web3privacy for the media partnership, and to @cakewallet, @ZcashCommGrants, @Logos_network, @OctantApp, and @ethereumfndn for their generous matching funds 🙏❤️ x.com/OpenObservator…

The funding round is now closed. Thank you to everyone who showed up to #FundInternetFreedom. We’re tallying donations and matching allocations, and will share results soon. Support is still encouraged, but new donations won’t count toward this quadratic funding round.

The Internet Freedom funding round by @torproject and @FundingCommons closes today.

Thank you for supporting projects like @SecureDrop, @BPFreeSpeech, @open_archive, @OpenObservatory, @PasKoocheh, @unredacted_org, @guardianproject, and many more! #FundInternetFreedom

@_franzihei thank you!

Long live internet freedom! ✊ Our community is used to quadratic funding rounds quite a bit already, but this must be the first time (?) that such a funding mechanism actually branches out of our Ethereum bubble. Exciting! Let's support them - I just participated 🖤

【网络审查研究者王一言回中国后失联近2年】中国人权对网络审查研究者王一言持续失联深表关切，并呼吁中国政府立即说明其下落和现状，保障其人身安全和基本权利。根据公开资料，王一言（Yiyan Wang，又名 Gaukas Wang）是一位网络安全研究者和开源社区贡献者，长期从事中国互联网审查、防火墙技术以及反审查工具的研究。他于2018年前往美国，就读于科罗拉多大学博尔德分校（University of Colorado Boulder），并于2021年以最高荣誉（summa cum laude）获得电子与计算机工程学士学位。此后，他继续在该校攻读硕士和博士学位，师从网络审查研究专家 Eric Wustrow。 王一言长期活跃于国际开源社区。他曾表示，自2017年以来一直致力于开发帮助用户突破互联网审查的技术工具。在其个人主页首页，他引用了一句中国互联网发展史上的著名话语： “Across the Great Wall we can reach every corner in the world.”（跨越长城，走向世界。） 这句话诞生于1987年中国与国际互联网建立首次电子邮件连接的历史时刻，象征着开放互联网、自由交流与连接世界的理想，也体现了他长期关注信息自由与开放网络的理念。 王一言的研究重点包括中国防火墙（Great Firewall）、网络审查测量、翻墙协议分析以及审查规避技术。他参与国际学术合作和开源项目，为理解互联网审查机制及其影响作出了重要贡献。 据朋友和同行反映，王一言于2024年夏季返回中国。此后不久，他与外界失去联系。自2024年7月以来，外界无法确认其行踪，也无法通过其惯常渠道与其取得联系。迄今其具体处境仍然不明。 中国人权目前无法独立核实王一言失联的原因。然而，鉴于中国政府长期以来对人权捍卫者、记者、律师、学者以及从事敏感议题研究人员的打压记录，我们对其安全状况深感担忧。 中国人权呼吁： 中国政府立即说明王一言的下落和法律状态； 如其被限制人身自由，应允许其与家属和律师联系； 保障其人身自由、学术研究自由和表达自由； 国际学术界、网络安全研究界、开源社区和人权组织持续关注王一言案件； 欢迎任何了解王一言近况或掌握相关信息的人士与中国人权联系，以便核实情况、推动国际社会关注并开展有效声援。 互联网自由和学术研究不应成为被惩罚的理由。我们呼吁中国政府保障王一言的人身安全，并尽快让外界获知其真实情况。 中国人权同时欢迎任何知情人士提供与王一言有关的信息，包括其近况、法律状态或其他可核实线索。任何信息都可能有助于外界了解其处境，并推动国际社会采取行动予以关注和声援。 Human Rights in China（中国人权） 2026年6月15日

@xeovo @FundingCommons amazing! thank you! 💜

Xeovo contributed to Tor × Funding the Commons (@torproject & @FundingCommons). The campaign helps projects that build privacy, anti-censorship and secure journalism tools. hub.xeovo.com/posts/198-xeov…

@ANAST_Crypto @torproject @girlgone_crypto @RoxomTV @WalkerAmerica The X spaces has ended, but the actual campaign is still live! Here is the link for more information. internetfreedom.torproject.org

true, not 'new', but still and always relevant. Internet freedom has declined for 15 consecutive years. We wish we'd be talking about something 'new'. :)

@ethereum @torproject that’s an old story talk about something new

Ethereum is inspired by tools that keep the internet open under pressure. @torproject protects freedom online by routing traffic through distributed relays, reducing tracking, surveillance, and censorship.
