Tackling Privacy Management with Aline Deparis, CEO of Privacy Tools

Our online privacy is at stake these days. Big companies are trying to get our personal information everywhere, and that could lead to data leaks, blackmailing, spam emails, phishing, scams, etc. Not protecting our data isn’t protecting ourselves. So, this time, we’ll talk about five open-source and free-to-use privacy tools that you can support via Kivach. As we’ve mentioned in previous articles, is a powerful and user-friendly charity platform based in Obyte. It’s designed to donate cryptocurrencies to open-source projects on GitHub. Besides, it possesses a unique feature: This way, the crypto donation would flow like a cascade, and expensive middlemen fees (e.g., Patreon or PayPal) would be eliminated. Kivach the recipients have the option to donate a percentage of donations to other open-source projects, automatically. Let’s look into some interesting privacy tools that you can use for free, and that may receive your . support via Kivach 1. Signal This is a highly regarded open-source messaging app known for its commitment to user privacy and security. It was launched in 2014 by cryptographer Moxie Marlinspike and Brian Acton, a co-founder. The app's user base has steadily grown over the years, reaching around 40 million users worldwide by 2022. WhatsApp Signal's standout feature is its It offers text messaging, voice, and video calls, as well as the ability to send multimedia messages. Signal also provides features like disappearing messages, group chats, and support for voice and video conferences. Its commitment to open-source development and privacy-focused design has earned Signal a loyal and expanding user base, including individuals, activists, journalists, and those concerned about their online privacy. end-to-end encryption, which ensures that only the intended recipient can decrypt and read messages. Currently, Signal is maintained by the nonprofit Signal Technology Foundation. The app is completely free to download and use on mobile devices (Android & iOS) or desktop machines (Windows, Linux, and macOS). They welcome donations in numerous national currencies and also in cryptocurrencies. You can donate to them using Kivach, where they appear as , and signalapp/signal-android signalapp/signal-desktop, signalapp/signal-server, signalapp/signal-ios. 2. GrapheneOS GrapheneOS is a privacy-focused and security-centric open-source operating system designed for mobile devices. It was created in 2014 by Daniel Micay, a highly regarded security researcher and developer. GrapheneOS places a strong emphasis on enhancing the security and privacy of Android smartphones and has gained popularity among users seeking a more secure mobile experience. includes features such as a security-hardened kernel (the connection between hardware and software), fine-grained permission controls, enhanced encryption, and regular security updates. , . For this reason, it doesn’t offer Google apps or services natively. They’re only available through a sandboxed compatibility layer. GrapheneOS It provides a more secure environment for smartphone users and aims to protect against a wide range of potential threats including surveillance and unauthorized data access Funding for GrapheneOS primarily comes from user donations, sponsorships, and community support, allowing it to remain independent and focused on user privacy and security. They accept PayPal, wire transfers, GitHub Sponsors, and several cryptocurrencies. You can help them with Kivach too: grapheneos/vanadium. 3. Pi-hole This is an ad-blocker software specially designed for small, energy-efficient devices like Raspberry Pi. It was initially created by Jacob Salmela in 2014 and has since grown into a widely used project with contributions from the open-source community on GitHub. Besides Raspberry Pi, it’s also available for Ubuntu, Debian, Fedora, and CentOS Stream. Unlike other ad-blockers, Pi-hole can block ads and tracking domains in a whole network, like a firewall. It maintains an extensive blocklist of known ad-serving domains and can be customized to filter additional content. Pi-hole's user base spans tech-savvy individuals, families, and organizations seeking to reduce the intrusion of online ads and protect against potential malware. After installation, it’s necessary to set Pi-hole as the computer’s DNS server, and it’s also possible to pair it with a VPN to use it remotely —for instance, in a smartphone. The project runs entirely on donations. They accept funds via Patreon, GitHub Sponsors, Google Play, PayPal, and several cryptocurrencies. You can use the latter option through Kivach, where you’ll find them as pi-hole/pi-hole. 4. WireGuard A VPN (Virtual Private Network) is a technology that creates a secure, encrypted connection over the Internet, That’s what WireGuard does as a completely free-to-use app for Windows, macOS, Linux, Ubuntu, Android, iOS, and other operating systems. protecting your online privacy and data by masking your IP address and routing your traffic through a remote server. It was created by Jason A. Donenfeld and first released in 2015. WireGuard has rapidly gained popularity for its simplicity, robust security, and speed, making it a go-to choice for individuals and organizations seeking a reliable VPN solution. It is known for its minimalistic codebase, making it easier to audit for security vulnerabilities. That’s why a long list of commercial VPN brands have chosen it as a connection protocol. The WireGuard team accepts donations via PayPal, GitHub Sponsors, Patreon, Liberapay, Bitcoin, and Stripe. You can also send them more cryptocurrencies through the and Kivach, where they’re available as Counterstake Bridge wireguard/wireguard-go. 5. Cryptomator CryptoMator is an open-source encryption software that provides secure, client-side encryption for cloud storage services. It was created in 2014 by Sebastian Stenzel for personal use and later launched to the public with the German company Skymatic GmbH. CryptoMator's user base comprises individuals, professionals, and organizations looking to enhance the privacy and security of their files stored in the cloud. Key features of CryptoMator include end-to-end encryption, which ensures that The software is available on various platforms, including Windows, macOS, Linux, iOS, and Android, making it versatile for users across different devices. However, it’s important to note that only desktop versions are free to use. files are encrypted on the client side and remain private even when stored on third-party cloud services like Dropbox or Google Drive. The only thing you’ll need to get started is installing the software and creating a password. No more complex steps are required. To support the free version, they accept donations via PayPal, credit card, bank transfers, and CoinPayments. If you want to avoid all the middlemen fees involved on these platforms, you can use Kivach to send them cryptocurrencies. They appear as cryptomator/cryptomator. Bonus: Blackbytes To reach a good level of privacy, you’ll need to combine several privacy tools. We offer you another one in Obyte: its privacy coin, . . To make private transactions, GBB divides the internal data of its transactions into two parts. One part is publicly available and registered in the DAG as an undecipherable hash. Blackbytes (GBB) This is an asset designed to be used exclusively for P2P, anonymously, and outside centralized cryptocurrency exchanges The rest of the related information (amount, involved addresses, dates, parent transactions, etc.) is sent directly to the recipient(s) via end-to-end encrypted private message. Therefore, only the involved users have this data on their own devices (in the form of a digital file), offline. Blackbytes can also be sent online. You can buy and sell Blackbytes through the and several integrated chatbots . Additionally, just to increase your privacy level, you can enable the browser Tor from your wallet, by adjusting your Global Preferences (Settings). Obyte wallet (Chat Tab – Bot Store – Blackbytes.io Exchange) Remember to tell them! If you’re going to send some cryptocurrencies via Kivach to any open-source project of your preference, don’t forget to tell them about the donation. Initially, they may not know that they received something. If they don’t have an Obyte wallet yet, they’ll need to download it and pass through a (Chat Tab – Bot Store – GitHub Attestation Bot) to verify their GitHub account and claim the funds.

Updated - 01/13/20 The universal access to the Internet and advancements in technology lead to the necessity of the reinterpretation of such notions as privacy and personal data. The government's attempts to regulate and take control of the "network" life in all its manifestations, even with good intentions, turn out to be ineffective, ill-conceived and somewhat inadequate, which causes extremely negative reactions from the public and even resistance. That's why we can find so many products that offer a solution for those who tend to preserve their rights for anonymity. This article aims to provide you with an analysis of 10 best Internet privacy tools existing thus far: private Web browsers, messengers with encrypted file storages, DNS, and Emails. What are the best Internet privacy tools? 1. Utopia p2p Utopia p2p is an ecosystem developed right for the sake of total security and anonymity on the Web. It includes browser Idyll, uMail, instant messenger, uMaps, a wallet and own digital currency Crypton and other builts-in. It is a decentralized peer-to-peer network. It means that there is no single data warehouse for users’ data storage. Now, each client is a peer. The ecosystem creates his personal server for data storage. Access to it opens a personal key that is generated during the anonymous registration. Each user participates in the transmission of data, but only the recipient has a key to decrypt and see the content of the message. Also, Utopia applies the most advanced and multilevel encryption method, including a high-speed Elliptic Curve25519 and 256-bit AES. Such a method allows protecting and saving all confidential data of the users. Utopia p2p is a multifunctional ecosystem where the registration, communication, files transfer are anonymous and highly protected. API allows automating financial transactions, invoicing, receiving payment, transfer, receiving, and sending order information to their customers. That's especially beneficial for businesses. I consider it to be anew level of privacy and convenience. Besides, the ecosystem is available for free, there are no functional errors and it is famous for its stability of using. 2. Tor Tor browser is a modified version of Mozilla Firefox. Using this web browser allows you to hide your location, IP address, and other identifying information from regular websites. Earlier, in order to connect to Tor, you needed special knowledge that the average computer user did not have. Now, the situation has changed. Tor Browser simplifies the process of protecting personal data, but at the cost of reduced performance. The browser works according to the principal of the Onion Router.The data is encrypted several times with the transmission from server to server (3 randomly chosen servers of Tor network) and then transferred through the virtual channel. The decryption is processed the same way. Traffic between the Tor network and the target resource is not encrypted. Therefore, if the user wants to transmit sensitive information over the Internet, you still need to take care of confidentiality through the use of https or another pass-through encryption protocol, as well as authentication mechanisms. In addition, when using the Tor network, the user still has the opportunity to visit blocked sites. 3. Wire The former Skype vice president left the company when Microsoft bought it and decided to develop another one. This is how Wire appeared. It is a messenger with end-to-end encryption for making calls, exchanging images, videos, documents, GIFs, and so on. Wire promises not to publish or send your information to anyone and doesn't contain ads. That's great. The registration is anonymous, you just need to provide your username. The messenger is available on three platforms and is equipped with a message synchronization system. Wire is great for private and secure group conversations with up to 128 people. 3. ProtonMail ProtonMail is an email with encryption and setting message lifetime. The service quickly encrypts mail between ProtonMail users. You can send encrypted messages to users of other mail systems. Moreover, you can specify the lifetime of the message (after which the letter will be automatically deleted). ProtonMail claims that the devs do not have access to your messages due to end-to-end encryption. When registering, you do not need to indicate your real first and last name. However, during the registration, a "check for bots" is performed: you will have to specify an email or phone number. Thus, the condition of anonymity is not fulfilled. At the same time, the service rejects some of the entered email addresses, which is also disappointing sometimes. 4. Tails Tails is a Debian-based distribution for Linux that ships with Tor anonymizer, encryption and security software. The Tails system can be downloaded to any computer from a regular flash drive or SD card, which makes it convenient to use for safe Internet surfing. All Internet connections are made via TOR, and messages are encrypted with modern cryptographic means. Tails does not save any traces of your Internet activity. Tails also has support for the anonymous I2P network, which provides anonymous use of applications. The network is based on IP-style messaging, but there is also a library for creating reliable TCP-style streaming connections. Tails supports the mode of saving user data between downloads; a separate encrypted partition is created to store data on a USB drive, TrueCrypt is used for encryption. Tails also provides protection against the analysis of amnesic in the computer's memory, in the process of shutting down and removing the media, all RAM is automatically cleared. 5. Brave browser Brave browser is Firefox's child. It is an open-source product based on Chromium. Its distinguishing feature is a high level of visualization of effects from the use of security mechanisms. Brave's home page displays visual statistics in the form of special counters for blocked trackers, ad modules, redirects from http to https, as well as time saved as a result (the creators of Brave promise to load web pages 2 to 8 times faster than Chrome and Safari). Regarding the collection of personal data, Brave implements Anonize technology, which allows transactions based on the principle of "anonymous accounting." To apply this technology, cryptographic methods of evidence with zero disclosure are used. Moreover, the browser is free. 6. Signal Signal Private Messenger is Edward Snowden's favorite messenger with not so bright reputation. It gives users the ability to exchange messages and files, make calls. All transmitted messages, files, and calls are protected by end-to-end encryption, and the messages can be stored only on the user's device if he/she decides to make a copy. As for metadata, this is the only thing that service owners can know - the date when a particular user was online. But as it turned out, there are situations when all efforts to encrypt Signal information are in vain. During the process of migrating from the Chrome extension to a full-fledged desktop client Signal exports user messages to unencrypted text files. 7. Threema Threema is also secure services because it performs E2EE of all the data exchanged by the users, whether it is messages, chats, media files, etc. Threema uses an open-source cryptographic NaCl library for encryption. The keys are created and stored in protected folders on users' devices. It excludes private data access or copying. In addition, you do not need a phone number or email address to use the app. This allows you to use Threema entirely anonymously. In terms of functionality, Threema is in no way inferior to the market leaders. The messenger can send text messages, photos, and short videos, share its location, record voice messages. In addition to individual communication, group chats with several contacts are allowed. The main disadvantage of it is it's a commercial product, and you have to pay for the usage - $3.07. 8. MailVelope Mailvelope is a free browser add-on which uses the OpenPGP standard and is designed for webmail. No additional programs are required to download or install. With Mailvelope, you can Create encryption key pairs, export your public key (then you can share it with others), import other people's public keys. You can create, encrypt and sign emails, decrypt and verify letters, encrypt and decrypt attachments. Your interlocutors do not need to install Mailvelope. Any OpenPGP-compliant program is enough. Unfortunately, Mailvelope lacks many of the features Thunderbird, Enigmail, and GnuPG have, but today this is probably the easiest way for a webmail user to start using E2EE. Conclusion Each of these services serves the noble aim - your security and anonymity on the Web. Whatever tool you would choose, use it right - not for the sake of suspicious and illegal activity. I hope this article helped you to clarify the situation on the market of Internet privacy tools. Stay safe!

Internet Privacy Tools for 2019

This Year's Top 7 Online Privacy Tools

The cypherpunk movement started with a mailing list in 1992, but there were pioneers of online privacy even before that. David Chaum, an American computer engineer and talented cryptographer, is likely the pioneer of all this. He wasn’t on the mailing list back then (to our knowledge), but he was definitely creating new software with cryptography to preserve our anonymity and improve older systems. He’s known to be the inventor of digital cash, long before Satoshi Nakamoto. That’s why he deserves a mention as an honorary cypherpunk, or, just like Bloomberg called him, “The Godfather of Crypto.” After all, Chaum provided a lot of pieces that would come together to create Bitcoin, eventually. He was born to a Jewish family in Los Angeles, California (USA) in 1955, and got a doctorate in computer science from the University of California, Berkeley in 1982. The same year, he launched a whole conference about cryptography and its potential uses, and that was actually the kind of bold move a cypherpunk would make since the US government was paying close attention to these systems —in a bad way. In the early 1980s, cryptographic technology was classified as a munition under the International Traffic in Arms Regulations (ITAR), which meant that exporting (even creating or sharing) strong encryption technology was heavily restricted. Chaum avoided being legally targeted for this by creating the International Association for Cryptologic Research (IACR) at the same time, securing protection as an international scientific association by the United Nations. The IACR still exists today, and it organizes several annual conferences on cryptography across the globe. After that first Crypto conference, Chaum landed as a professor at the University of New York and the University of California. Ecash In 1983, Chaum published a paper called “Blind Signatures for Untraceable Payments”, in which he described a new privacy-preserving financial technology built with cryptography. That’s the groundwork of Ecash, the first privacy-oriented electronic cash system in the wild, that would come to life when Chaum founded the company DigiCash in 1989. This system allowed users to store money in a digital format on their computers and spend it anonymously at any shop that accepted Ecash. It aimed to protect their privacy by ensuring that transactions didn't require opening accounts with vendors or transmitting credit card numbers. As we mentioned, the core technology behind Ecash was the use of blind signatures. They are digital signatures where the message content is hidden (blinded) before being signed. This technique ensures that the signer can’t see the message content, providing unlinkability between the withdrawal and spending of the digital currency. As a result, the bank couldn’t trace individual transactions, preserving the user's anonymity. However, the bank was still necessary as a middleman, and the money's ultimate origin was still a central bank. Ecash was a system, not a currency by itself, and, of course, it wasn’t as decentralized as modern cryptocurrencies. That’s maybe why, despite initial interest from large banks, DigiCash ended up declaring bankruptcy in 1998. The concept, however, opened the path for future developments in digital currency and cryptographic privacy solutions. More Than Ecash The cryptographic and privacy-oriented efforts by David Chaum didn’t end with Ecash or the blind signatures. One of his notable achievements was the development of mix networks in 1981, an anonymous communication system. Mix networks work by encrypting and batching messages from multiple senders, reordering and obfuscating them at each server until they reach their final destination. This concept is foundational to modern anonymous browsing tools like Tor, emphasizing Chaum's pioneering role in enhancing Internet privacy. Chaum also introduced undeniable signatures in 1989, which allow the signatory to control who can verify the signature through an interactive process. This ensures that signatures are considered valid unless actively disavowed by the signer. Additionally, in 1991, he developed group signatures, enabling a group member to sign messages on behalf of the group anonymously, with a group manager capable of revoking anonymity if necessary. Another significant area of Chaum's work is in trustworthy voting systems. Starting in 1981, he proposed a voting system that maintains voter privacy while ensuring verifiable tallies using mix networks. His later work included SureVote in 1991, which allowed secure voting from untrustworthy systems, and a series of cryptographically verifiable voting systems like Prêt à Voter, Punchscan, and Scantegrity. These systems have been employed in some real-world elections. More recently, Chaum has been working on the XX Network, “a high-speed privacy-protected blockchain with quantum-resistant consensus and currency with metadata shredding via mixing”. In other words, this network is designed with robust encryption for a variety of privacy-centric use cases, including secure messaging, anonymous transactions, and protecting user metadata from surveillance. Tools for Privacy As Chaum and other cypherpunks have pondered, the use of privacy tools today is even more important than in the last century. According to the “Zimmerman Law” (another remarkable cypherpunk), “The natural flow of technology tends to move in the direction of making surveillance easier (…) the ability of computers to track us doubles every eighteen months.” The sad truth is that surveillance is only the first step to abuse —from cybercriminals, corporations, and governments. We need to protect our information and our funds to the best of our ability. Luckily for us, there are numerous tools and decentralized ecosystems that will let us do it just by using them, and one of them is Obyte. This decentralized ecosystem offers a compelling solution for those seeking to protect their online privacy and financial freedom. Its Directed Acyclic Graph (DAG) structure sets it apart from blockchains by providing a more decentralized and censorship-resistant framework. Since there are no miners, "validators", or other middlemen, only users are in charge of their own transactions and data. This architecture allows for secure and immutable operations, ensuring that no single entity can control, censor, or somehow manipulate the network. With Obyte, users can conduct their digital activities with greater confidence, knowing that their information and financial transactions are protected. The platform’s robust security measures and decentralized nature make it an ideal choice for anyone looking to maintain their privacy and autonomy in the digital age. By leveraging Obyte’s technology, individuals can safeguard their data and assets, enjoying a higher level of freedom and security online —just like cypherpunks have wanted.

That’s maybe why, despite initial interest from large banks, DigiCash ended up declaring bankruptcy in 1998. Ecash was a system, not a currency by itself, and, of course, it wasn’t as decentralized as modern cryptocurrencies. The concept, however, opened the path for future developments in digital currency and cryptographic privacy solutions. More Than Ecash The cryptographic and privacy-oriented efforts by David Chaum didn’t end with Ecash or the blind signatures. One of his notable achievements was the development of mix networks in 1981, an anonymous communication system. Mix networks work by encrypting and batching messages from multiple senders, reordering and obfuscating them at each server until they reach their final destination. This concept is foundational to modern anonymous browsing tools like Tor, emphasizing Chaum's pioneering role in enhancing Internet privacy. Chaum also introduced undeniable signatures in 1989, which allow the signatory to control who can verify the signature through an interactive process. This ensures that signatures are considered valid unless actively disavowed by the signer. Additionally, in 1991, he developed group signatures, enabling a group member to sign messages on behalf of the group anonymously, with a group manager capable of revoking anonymity if necessary. Another significant area of Chaum's work is in trustworthy voting systems. Starting in 1981, he proposed a voting system that maintains voter privacy while ensuring verifiable tallies using mix networks. His later work included SureVote in 1991, which allowed secure voting from untrustworthy systems, and a series of cryptographically verifiable voting systems like Prêt à Voter, Punchscan, and Scantegrity. These systems have been employed in some real-world elections. Chaum's work Chaum's work Starting in 1981, he proposed a voting system that maintains voter privacy while ensuring verifiable tallies using mix networks. More recently, Chaum has been working on the XX Network , “a high-speed privacy-protected blockchain with quantum-resistant consensus and currency with metadata shredding via mixing”. In other words, this network is designed with robust encryption for a variety of privacy-centric use cases, including secure messaging, anonymous transactions, and protecting user metadata from surveillance. XX Network XX Network Tools for Privacy As Chaum and other cypherpunks have pondered, the use of privacy tools today is even more important than in the last century. According to the “Zimmerman Law” ( another remarkable cypherpunk ), “The natural flow of technology tends to move in the direction of making surveillance easier (…) the ability of computers to track us doubles every eighteen months.” The sad truth is that surveillance is only the first step to abuse —from cybercriminals, corporations, and governments. another remarkable cypherpunk another remarkable cypherpunk We need to protect our information and our funds to the best of our ability. Luckily for us, there are numerous tools and decentralized ecosystems that will let us do it just by using them, and one of them is Obyte . We need to protect our information and our funds to the best of our ability. Obyte Obyte This decentralized ecosystem offers a compelling solution for those seeking to protect their online privacy and financial freedom.

Commonly, we only consider the members of a famous mailing list initiated by Tim May, John Gilmore, and Eric Hughes in 1992 as ‘cypherpunks’. Satoshi Nakamoto was around, too, and that’s partly why the mailing list became famous later. But cypherpunks are much more than people who just happened to be there. They’re skilled coders and privacy activists dedicated to creating new digital tools to foster online freedom and social change. Sometimes, sadly, they even pay a high price for it. That was the case with Julian Assange, and that’s also the case now with the Tornado Cash founders: Alexey Pertsev, Roman Semenov, and Roman Storm. Unlike Assange, they weren’t there for the mailing list in the 90s (they were far too young), but they can be considered cypherpunks for their considerable contribution to online privacy. Also, as with many other cypherpunks, we don’t know a lot about them beyond Tornado Cash and its legal intricacies. We know some things, though. All of them are of Russian origin, and their ages range between 31 (Pertsev) and 35 (Semenov). Pertsev was based in the Netherlands, and his co-founders were in the United States. The latter is also the country in which they registered PepperSec Inc. in 2018. This is a cybersecurity company staffed by white hat hackers —including the founders. Before this, they were doing different projects inside and outside the crypto world —and around Ethereum, specifically. For instance, Storm was a developer in the POA network, an Ethereum-based platform that offers a framework for smart contracts, and it’s now part of the Gnosis ecosystem. Pertsev was an independent security consultant in the meantime. And their lives would change in 2019 when they released Tornado Cash. What is Tornado Cash? Well, it’s apparently a headache for authorities, but it wasn’t done on purpose. In essence, Tornado Cash is a privacy tool on Ethereum that helps users keep their transactions mostly anonymous. When you send Ethereum-based tokens through Tornado Cash, it mixes your coins with those of other users, making it difficult for anyone to trace where your money came from or where it’s going. This way, your financial activities stay private. Here’s how it works: you deposit your cryptocurrency into Tornado Cash, which gives you a secret note. Later, you can use this note to withdraw your funds to a different address. Since your coins get mixed with others in the pool, the connection between your original deposit and the final withdrawal is broken, ensuring your privacy. It’s like putting your coins into a blender with others and then taking it out in a way that no one can tell whose money is whose. Does that sound harmless? It is, in theory. It could work to protect yourself against surveillance, to keep a business transaction secret, or to safely fund a project or group in a hostile territory. Sadly, it also worked for the malicious hacking team dubbed Lazarus Group to launder around $625 million in crypto from a robbery to the Ronin Network in 2022, and likely other illegal endeavors. That’s assuredly the worst use case for the tool, and the creators of this tool are being blamed for it. Money Laundering Accusations The same year of that really big hack and money laundering operation by the Lazarus Group, in August, the U.S. Office of Foreign Assets Control (OFAC) blacklisted Tornado Cash, alleging it was used for laundering billions in virtual currencies. This led to the suspension of developer accounts and the takedown of their domains. The blacklisting resulted in severe restrictions, including asset freezes and transaction bans, impacting anyone associated with Tornado Cash, even outside the U.S. Shortly after, Alexey Pertsev was arrested in Amsterdam, accused of money laundering through Tornado Cash. Pertsev faced significant legal hurdles, spending over nine months in prison before being placed under house arrest. His trial concluded in May 2024 with a sentence of 64 months in prison, which he is currently appealing. Pertsev's legal team is actively working on the appeal, but it may take several months before a new hearing is scheduled. Roman Storm and Roman Semenov were similarly accused in the U.S. in August 2023. Roman Storm was arrested in Washington but was released on a $2 million bond pending his trial. His trial is set for September, where he will face charges similar to those against Pertsev. Roman Semenov is also under investigation, but he’s said to remain at large. Despite these legal challenges, the Tornado Cash community and various advocacy groups have shown strong support for the developers. Organizations like Coin Center, DeFi Education Fund, and the Electronic Frontier Foundation have voiced their support and are assisting in the legal battles. The crypto community continues to rally behind the developers, emphasizing the importance of privacy tools in the digital age. What’s next? Tornado Cash itself remains operational as a decentralized protocol on the Ethereum network, with significant funds still deposited in the platform. However, all the services related to it that aren’t decentralized (domains, node providers, webpages, user-friendly interfaces) are being blocked by a lot of companies that aren’t willing to face the OFAC blacklisting. Also, if a centralized crypto exchange or stablecoin relates your tokens with Tornado Cash, they may freeze your funds, for the same reasons. In the end, despite it being a decentralized platform available for everyone, there are feasible ways to censor this and other similar services on blockchains. That doesn’t mean the work of Pertsev, Semenov, and Storm was for naught. Besides the fact there are other numerous crypto mixers around, the ongoing legal proceedings against Tornado Cash developers are a wake-up call that highlights the complex intersection of privacy, technology, and regulation around decentralized services. Our online privacy is something worth fighting for, and no centralized party seems really interested in letting us have that right. Creating code for it shouldn’t be a crime. As cypherpunks say in their manifesto, “We must defend our own privacy if we expect to have any.” Obyte, as a Directed Acyclic Graph (DAG) crypto network, offers a higher level of censorship resistance than any blockchain, and that translates to a higher level of privacy as privacy tools like Tornado Cash cannot be censored. It offers a decentralized, autonomous platform that operates independently of centralized intermediaries such as block producers in blockchains. Unlike blockchain services that can be censored or blocked by block producers due to regulatory pressures, Obyte's decentralized nature ensures that users retain control over their transactions without the risk of third-party interference.

The famous cypherpunk mailing list from which Bitcoin (and other privacy tools) came was founded in late 1992 by the activists Eric Hughes, Tim May, and John Gilmore. However, this is far from being the only merit attributed to Gilmore. Indeed, while that specific mailing list isn’t active anymore, other important projects launched or supported by Gilmore are still around, always helping to keep our privacy and digital rights. Born in 1955 in Pennsylvania (US), . Gilmore's journey as a programmer began in 1982 at Sun Microsystems (now Oracle), where he was the fifth employee. John Gilmore is a pioneer in software development and cryptography, who made significant contributions that continue to shape the digital landscape He focused there on further developing Berkeley Software Distribution (BSD), an open-source operating system. In 1985, he also co-authored the Bootstrap Protocol, which evolved into DHCP, a fundamental mechanism for assigning IP addresses on networks. This essentially ensures that devices connected to a network can communicate with each other, forming the backbone of modern Internet connectivity. his efforts Likewise, Gilmore is a frequent collaborator in free software and has been involved in various GNU projects. They include maintaining the GNU Debugger and initiating GNU Radio, demonstrating his commitment to fostering open-source solutions. Besides, his entrepreneurial spirit led him to found Cygnus Solutions in 1989. This was a company dedicated to supporting free software and was sold to Red Hat in 1999. Electronic Frontier Foundation (EFF) In 1990, Gilmore took another step to fight for privacy and freedom online. Along with John Perry Barlow (author of the ), and Mitch Kapor (creator of Firefox), they founded the Electronic Frontier Foundation ( ). Declaration of Independence of Cyberspace EFF This is an NGO with a mission to safeguard online rights, whether it entails combatting mass surveillance or defending freedom of expression worldwide. Not only do they advocate for these causes, but they also equip people with the requisite tools and insights to fortify their online defenses. Through legal advocacy, the EFF takes on cases involving privacy violations, government surveillance, and free speech issues. They also work to shape policies and legislation that protect digital rights, promote Internet freedom, and develop technologies to enhance online privacy and security. One notable example is HTTPS Everywhere, a browser extension created in collaboration with the Tor Project. HTTPS Everywhere automatically switches websites from insecure HTTP to secure HTTPS, enhancing users' security and privacy while browsing the web. Other significant EFF software projects are Privacy Badger, a browser extension designed to block online trackers and advertisements; and Let's Encrypt, a free, automated, and open certificate authority that enables website owners to obtain and install SSL/TLS certificates for secure HTTPS connections. Cypherpunks and Activism Gilmore didn’t create any form of digital money himself, but he supported as a movement from the very beginning. The first physical meetings were held between Eric Hughes’s house and Cygnus Solutions headquarters in California, whereas the mailing list was originally hosted on toad.com, a domain owned and maintained by Gilmore. The mission of cypherpunks is protecting privacy and freedom by using cryptographic tools, something fully shared by : the cypherpunks Gilmore too “I want a guarantee—with physics and mathematics, not with laws—that we can give ourselves things like real privacy of personal communications. Encryption strong enough that even the NSA can’t break it.” Additionally, Gilmore has been a vocal advocate for digital rights and civil liberties. such as the creation of the FreeS/WAN project for IPsec encryption and sponsorship of the EFF's Deep Crack DES cracker. Both projects worked towards making digital communication more secure by either enhancing encryption standards or demonstrating weaknesses in existing ones. He’s also been involved in the development of numerous software projects aimed at enhancing digital security and privacy, Gilmore's commitment to promoting Internet freedom has also led him to support initiatives aimed at increasing transparency and accountability in government surveillance practices. He has been involved in legal battles challenging unconstitutional surveillance and censorship, demonstrating his dedication to defending civil liberties in the digital age. A remarkable case was , where he challenged the requirement to show identification for domestic air travel, arguing it violated his constitutional rights to travel. He also objected to the lack of transparency regarding the directive mandating ID checks, which is fair: although the courts reviewed the Security Directive privately, its contents remain undisclosed to the public. This is deemed an unconstitutional “ .” Sadly, despite Gilmore's claims, the court ruled against him for now. Gilmore v. Gonzales secret law Against Censorship Gilmore, as much as other cypherpunks, has a firm position against censorship. He’s still active in the fight for privacy by like Freedom Box, a small device that works as an independent server to avoid surveillance; and Freedom of Movement, the legal battle against secret laws. , censorship is a social weakness, and it doesn’t offer any advantages. supporting projects For him “Censorship is a counterproductive social policy and weakens the national security, by suppressing the flow of useful information among the honest citizenry. Widespread use of encryption also enhances the national security, by making private information more truly private, and by making systems and networks harder for dishonest people to penetrate.” In these days of censorship and surveillance, we need decentralized and privacy tools more than ever. Luckily, developers and activists like Gilmore keep working to deliver them free to use. One of them is the . Obyte crypto network is structured as a Directed Acyclic Graph (DAG) to achieve consensus and record transactions. This decentralized approach ensures greater transparency, security, and resilience against censorship and surveillance. Its architecture enables peer-to-peer transactions without the need for intermediaries. Moreover, its open and permissionless nature fosters innovation, allowing developers to build decentralized applications (Dapps) and smart contracts on the platform. Obyte Besides, relying on the , users have the option to verify their personal information, such as their real name, while ensuring it remains securely stored in their wallet and nowhere else. This verified information can then be shared selectively with trusted parties, allowing others to check its authenticity using the Obyte DAG. Self-Sovereign ID features Importantly, users retain full control over what information they share. By decentralizing control and empowering users with sovereignty over their data and assets, Obyte paves the way for a more inclusive and equitable digital economy. Just like John Gilmore and other cypherpunks have dreamed of.

Have you ever paused to consider just how much of your personal life is floating around in the digital world? And what exactly are faceless companies and dubious people doing with it? It could be an unsettling thought, indeed. That's precisely why safeguarding your digital privacy is so crucial in today's interconnected age. It's all about ensuring your security and maintaining your autonomy —financial autonomy, data autonomy, etc. In this era, where every digital move you make is being monitored. Countries like North Korea, China, and Iran are notorious for their stringent Internet censorship policies, modifying the truth to their convenience. It's not merely about restricting access to certain websites; there are regions it's about overseeing virtually every aspect of your online presence and even manipulating your thoughts and money. Fortunately, there are initiatives aimed at addressing these concerns and championing your digital rights. Several organizations and projects worldwide are already there, aiming to use new technologies to reach freedom and privacy for everyone. And you could even collaborate with some of them. Let’s find out more below. Free Software Foundation (FSF) This organization is dedicated to preserving the ethos of free and open-source software (FOSS). They firmly believe in affording you the freedom to utilize, examine, adapt, and distribute software as you see fit. Moreover, they're fervently committed to disseminating knowledge and raising awareness about the significance of these principles. ** ** It was created in October 1985 by Richard Stallman and has been supported from its inception by digital freedom enthusiasts. Over the years, the FSF has achieved remarkable milestones, —ideated by Stallman in 1983. This initiative seeks to develop a fully free and open-source operating system. The GNU Project is considered the beginning of the FOSS movement, inspiring countless developers and users worldwide. with one of its most significant accomplishments being the coding and support of the GNU Project According to the published by Stallman: GNU Manifesto “I consider that the Golden Rule requires that if I like a program I must share it with other people who like it. Software sellers want to divide the users and conquer them, making each user agree not to share with others. I refuse to break solidarity with other users in this way. I cannot in good conscience sign a nondisclosure agreement or a software license agreement." With unwavering dedication, the FSF continues to strive towards its overarching goal: to foster a world where all software respects the fundamental freedoms of its users. They accept support in the form of donations . You can join the FSF community team, participate in campaigns, attend local events, or even organize activities in your own community. or volunteering Additionally, you can contribute through writing, blogging, or assisting with technical tasks such as maintaining websites or contributing to the GNU Project itself. Electronic Frontier Foundation (EFF) This NGO was founded in 1990 by John Gilmore, also a founding member of cypherpunks, along with John Perry Barlow (author of the ), and Mitch Kapor (creator of Firefox). Their mission revolves around safeguarding online rights, whether it entails combatting mass surveillance or defending freedom of expression. Not only do they advocate for these causes, but they also equip people with the requisite tools and insights to fortify their online defenses. Declaration of Independence of Cyberspace ** ** They also work to shape policies and legislation that protect digital rights and promote Internet freedom, and develop technologies to enhance online privacy and security. Education and awareness efforts are part of their job as well while offering support and assistance to individuals and organizations facing digital rights issues, providing guidance, referrals, and legal resources to navigate challenges such as censorship and surveillance. They operate worldwide. Through legal advocacy, the EFF takes on cases involving privacy violations, government surveillance, and free speech issues. It’s possible to donate to them, but also with your own skills. If you're a technologist, you can volunteer your skills to support software projects crucial to EFF's work. Additionally, you could also help with translations and mailing lists as an attorney, researcher, or artist. Every collaboration is welcomed. volunteer Privacy International (PI) Founded in 1990 by privacy activist Simon Davies, the primary goal of this charity is to restore agency over personal data. They tirelessly strive to ensure that neither governmental bodies nor corporate entities encroach upon personal online activities without explicit consent. Their efforts extend beyond rhetoric since they're actively developing tools to empower people to monitor who's tracking them online. It’s based in London but operates globally. ** ** Through research, advocacy campaigns, and strategic litigation, PI advocates for policies and practices that safeguard people's privacy in an increasingly interconnected digital environment prone to intrusion, from digital content to biometrics. Their work has had quite an impact, indeed. As we can see , Additionally, PI's advocacy efforts have led to 20 court decisions against exploitative practices in more than 50 countries and advancements in privacy legislation in 20 countries. They also have published numerous studies and research exposing abuses and supported public campaigns to build pressure against problematic conduct by companies and governments. on their website PI has influenced significant changes in business practices, with 39 companies adjusting their models or products since 2019, affecting over 3 billion people worldwide. To support their goals, you could donate, subscribe to their community, learn from them how to protect your online privacy, or join their privacy campaigns. The latter might involve to local authorities asking for accountability about privacy issues. sending letters Freedom Tech Not to be confused with TechFreedom ( interesting NGO, by the way), Freedom Tech involves cryptocurrencies more actively. Something that was to be expected since it’s an initiative in 2023 by Foundation, a crypto hardware wallet manufacturer. , activism, and real use cases of technology to avoid authority oppression. another launched This is a content hub for learners and experts alike to share their knowledge and resources about cryptocurrencies, privacy, open-source tools ** ** The platform was also made to promote and support software projects designed for freedom and privacy. Their ethos is fully aligned with crypto-anarchism and cypherpunk principles, empowering individuals through technology while championing privacy, decentralization, and cryptographic solutions to enhance personal freedom and autonomy. Inspired by the legacy of crypto-anarchists and cypherpunks who sought to use technology to enable individual sovereignty and resist oppressive control, Freedom Tech embraces the belief that technology should serve as a tool for liberation rather than surveillance. Individuals can contribute by sharing their unique narratives and perspectives, amplifying diverse voices, and establishing connections with like-minded individuals and projects. Additionally, backing freedom tech projects financially and raising awareness about them helps sustain and expand initiatives aimed at empowering users and safeguarding their privacy. They’ve shared of freedom tech software projects in need of support. their own list Open Technology Fund (OTF) This NGO was established in 2012 by privacy activist Libby Liu, then president of Radio Free Asia, an entity of the United States Agency for Global Media (USAGM). It operates internationally with a mission to promote freedom of expression and access to information by funding and supporting open-source technology projects. Through its initiatives, empower individuals and communities worldwide, particularly those living under repressive regimes, by providing them with tools to circumvent censorship and surveillance. It supports projects that develop and maintain technologies such as Tor, a decentralized network that enables anonymous communication and bypasses Internet censorship, as well as various encryption tools and digital security resources. OTF aims to Additionally, OTF advocates for Internet freedom through research and collaboration with civil society organizations and tech communities globally. including but not limited to OpenVPN, Global Surveillance Tracker, Filezilla, Digital Democracy, FreeWeChat, and Lantern. Any project aligned with their ethos could apply for funding. So, in this one, you could actually receive some help instead of giving it. Besides Tor, they financially support numerous open-source projects against surveillance and censorship, Bonus: Obyte We can say that the initiatives above support several software projects, and by collaborating with them (either with funds or time), we could make a difference. However, it’s also important to use privacy tools to protect your own data, funds, and online activities against surveillance, manipulation, censorship, or even robbery. could help you with it as much as the tools under the umbrella of these organizations. Obyte Our DAG-based and decentralized network aligns with the principles of and movements by providing a neutral, ownerless space that enhances individual privacy, security, freedom, and autonomy online. , without relying on traditional banking institutions, centralized companies or blockchain miners, and without fear of being censored or blocked. crypto-anarchism cypherpunk By using Obyte's decentralized platform, users can circumvent local limitations and securely chat and transact with anyone, anywhere in the world Moreover, Obyte's smart contract capabilities enable users to create and execute self-enforcing agreements without the need for intermediaries, further empowering people to exercise their autonomy and freedom online. Overall, Obyte network offers a means to preserve online rights and financial freedom anytime, anywhere. ** Featured Vector Image by Freepik
