<a href="https://evmcrispr.com" rel="noopener noreferrer" target="_blank">EVMcrispr</a> is a tool that simplifies interacting with smart contracts on EVM-compatible chains. It allows users to send transactions using intuitive, UNIX-like commands, making it easier to write complete scripts that encode complex transactions. This comprehensive tool can be used to improve almost all day-to-day blockchain operations, such as:<ul><li>Creating more efficient Decentralized Autonomous Organization (DAO) votes.</li><li>Launching DAOs and managing their configuration.</li><li>Performing DeFi strategies.</li><li>Running simulations on drafted on-chain actions.</li><li>Creating, sending and managing tokens.</li></ul> EVMcrispr effectively reduces the technical hurdles for web3 users to engage and carry out complex tasks using smart contracts. For instance, our domain-specific language is handy for expressing and transforming transaction data. In addition, we can combine different commands, so we can insert the command for managing Superfluid flows within the command to make an Aragon DAO vote or the command of sending a Giveth donation within the command to bridge tokens to the Gnosis Chain. It feels like modifying DNA when changing many parameters of a DAO all at once or when performing complex deployments that we must do in one transaction. EVMcrispr is the smart-contract gene-editing tool that has reduced the cost of operating DAOs and other blockchain protocols by orders of magnitude. It has been used by organizations such as <a href="https://curve.fi/" rel="noopener noreferrer" target="_blank">Curve</a>, <a href="https://aragon.org" rel="noopener noreferrer" target="_blank">Aragon</a>, <a href="https://nftx.io" rel="noopener noreferrer" target="_blank">NFTX</a>, <a href="https://1hive.org" rel="noopener noreferrer" target="_blank">1Hive</a>, <a href="https://giveth.io/" rel="noopener noreferrer" target="_blank">Giveth</a>, <a href="https://tecommons.org/" rel="noopener noreferrer" target="_blank">TECommons</a>, <a href="http://brightid.org/" rel="noopener noreferrer" target="_blank">BrightId</a> and <a href="https://agave.finance" rel="noopener noreferrer" target="_blank">Agave</a> to conduct complex votes within their DAOs. The tool has a terminal-like interface but <a href="https://docs.evmcrispr.com" rel="noopener noreferrer" target="_blank">clear documentation</a> with many examples, making it easy to start. By supporting the ongoing development and maintenance of EVMcrispr, Giveth donors can help to advance cutting edge blockchain technology and to enable the creation of more powerful and practical applications on EVM-based networks, such as Ethereum Mainnet and Gnosis Chain. You can find the source code in <a href="https://github.com/1hive/evmcrispr" rel="noopener noreferrer" target="_blank">this 1hive repository</a> under the GPLv3 license.

Welcome to the Giveth House! ﻿🦄﻿ A beautiful home, office, and community space located in Barcelona. The Giveth House has been available since 2017 to accommodate the greater Giveth community. When Giveth was founded in 2016, we knew it would be important to have a physical space to help facilitate the growth of Giveth. We also wanted the Giveth house&nbsp;to give the greater Web3 community a real location for events, gatherings, coworking, hack sessions and just a place to rest your weary head. Why Barcelona? Impassioned by first hand experiences of the Catalan struggle for independence, Giveth founders wanted to establish a local haven that represents freedom of thought and choice, and serve as a physical space to exercise that freedom. We are open to and inclusive of all walks of life that have equality, safety, comradery, freedom from tyranny, hierarchy and subservience in their philosophy.&nbsp; Until now we have sustained the Giveth House successfully through a revenue stream that has unfortunately recently diminished due to changes in the Ethereum network and market. We are asking for the support of the community at large to keep this wonderful IRL solar punk nexus alive! Centrally located near Plaça d'Espanya with easy access throughout the city and beach, the Giveth House welcomes anyone in the blockchain4good ecosystem who needs a place to stay, work or just hang out while in town. We want the space eventually to grow into an increasingly dynamic and regenerative locale where we can hold events for the different projects and become a strategic point to exchange ideas,&nbsp;create, and contribute to the community. Please support the Giveth House and help us maintain this gentle and warm, and open-door safe haven for the solar punk community that connects&nbsp;the greater Giveth ecosystem!

The <a href="https://wayback-machine.eth.limo/" rel="noopener noreferrer" target="_blank">ENS Wayback Machine</a> is a Web3 version of&nbsp;<a href="https://web.archive.org/" rel="noopener noreferrer" target="_blank">Internet Archive’s Wayback Machine</a>, allowing users to&nbsp;view historical versions of IPFS content associated with ENS domains. Users can search for specific ENS domains or URLs and view archived versions of those sites as they appeared on different dates in the past. This can be useful for researchers, historians, and anyone interested in tracking changes to websites over time or retrieving lost content.&nbsp; <a href="https://wayback-machine.eth.limo/" rel="noopener noreferrer" target="_blank"><img src="https://i.imgur.com/iDOAhbo.png"></a> Unlike the Wayback Machine maintained by the Internet Archive, the ENS Wayback Machine does not crawl the web or store archived web pages. Instead, it relies on the fact that the&nbsp;IPFS links are stored in the blockchain&nbsp;and can be accessed to view the content associated with a particular domain. This means that the service is only useful for ENS domains that have associated IPFS content. For example, you can use the ENS Wayback Machine to&nbsp;view the changes made to Vitalik’s website over the years. Just visit the ENS Wayback Machine website and navigate to&nbsp;<a href="https://wayback-machine.eth.limo/#/vitalik.eth" rel="noopener noreferrer" target="_blank">vitalik.eth</a>&nbsp;to see the different versions of the site through the top bar. You can also search for any other ENS domain in the&nbsp;<a href="https://wayback-machine.eth.limo/" rel="noopener noreferrer" target="_blank">search box</a>&nbsp;provided. <img src="https://giveth.mypinata.cloud/ipfs/QmeMF5PWQmGGrZETUh37TVnsEPEcDigu8UWPw5fmRscwYL"> Our team is steadfast in enhancing the functionality and user-friendliness of the ENS Wayback Machine. Our next step?&nbsp;Incorporating significant milestones into the timeline, such as the domain’s initial registration, renewals, and transfers.&nbsp;As we refine the design and evolve our service, we deeply value your insights.

Vocdoni Association

TL;DR: Vocdoni leads the way in opensource decentralized voting technology, with hundreds of thousands of votes processed for +300 organizations, including City councils, Political parties, Cooperatives, Football clubs, Associations, opposition groups under repressive regimes and more! We accomplished this using a custom L1 blockchain designed specifically for voting. Now, we are building DAVINCI, a new public good voting protocol that ensures anonymous, anticoercion, verifiable, and accessible elections using zkSNARKs and Homomorphic Encryption. DAVINCI is the first solution that meets all the criteria for a universal voting protocol, covering a wide range of use cases: from gasless and anonymous offchain voting for DAOs, with the same guarantees as onchain voting, to national-level official elections. <h2>Introducing DAVINCI: The future of voting on Ethereum</h2>Modern voting systems (whether paper-based, centralized digital voting, or onchain) suffer from significant flaws, including high costs, limited accessibility, and vulnerabilities to manipulation, bias, and vote buying. Achieving the highest standards of election security and fairness remains costly and complex, leaving billions without a secure digital participation option. Recurrent, low-cost voting is crucial for democratic resilience, but the existing systems lack the necessary technological infrastructure to support it. <h3>What is DAVINCI?</h3>DAVINCI (Decentralized Autonomous Voting Infrastructure for Non-Coercive Inclusion) is a new neutral and unstoppable voting protocol designed for privacy, scalability, and security. It enables high-frequency, low-cost elections while ensuring transparency, censorship resistance, anti-coercion, and integrity. Built as a Layer 2 solution on Ethereum, DAVINCI ensures votes remain tamper-proof and trustless, eliminating central points of failure. <h3>How DAVINCI Works</h3>DAVINCI leverages zkSNARKs and threshold homomorphic encryption (ElGamal) to provide end-to-end verifiability, anticoercion and anonymity, allowing voters to participate without compromising privacy. A distributed key generation (DKG) system, coordinated via smart contracts, secures encryption key creation while preventing manipulation. This ensures trustless election integrity without relying on any single entity. <h3>Technology &amp; Implementation</h3><ul><li>Privacy-Preserving Voting: Utilizes zkSNARKs for secure, anonymous voting with on-chain verifiability.</li><li>Scalable &amp; Efficient: Implements Gnark cryptographic libraries using BLS12-377 &amp; BW6-761 curves for fast recursive vote aggregation.</li><li>Ethereum Integration: Produces BN254 proofs, ensuring vote validity onchain with minimal computational overhead.</li><li>Accessible &amp; Decentralized: Designed to run on widely accessible hardware (64 GiB RAM), making it easy for anyone to join the sequencer network without requiring specialized infrastructure.</li><li>Flexible &amp; Gasless: Supports various governance models, including DAO voting, national elections, and community polls, with an efficient off-chain computation model.</li></ul> <h3>Why DAVINCI?</h3>DAVINCI is the only voting protocol that outperforms paper-based, centralized digital, and onchain voting. It meets the requirements for a universal voting solution.<a href="https://vocdoni.io" rel="noopener noreferrer" target="_blank"><img src="https://tomato-giant-grasshopper-196.mypinata.cloud/ipfs/bafybeihp67w6hzoog2e2ufgn44wqpin7i7l54wvin2sew2xxa3f36n3giu"></a><h3> </h3><h3>Roadmap &amp; Next Steps</h3><a href="https://vocdoni.io" rel="noopener noreferrer" target="_blank"><img src="https://tomato-giant-grasshopper-196.mypinata.cloud/ipfs/bafkreigqsitln2filgaid2s2kzmjorwxkamjs2bdfxjr4zcnqyauj3wiyy"></a> DAVINCI has completed its proof-of-concept phase and is now moving towards a testnet launch in Q2 2025. Our next milestones include:<ul><li>Testnet launch with a single sequencer</li><li>Audits</li><li>User Testing &amp; Pilots</li><li>Migration of current users of the Vocdoni protocol to DAVINCI</li><li>Community building around DAVINCI</li><li>Mainnet Deployment</li></ul>To achieve these milestones, we need funds to cover our running costs.<h3>Extended info &amp; repos:</h3><ul><li><a href="https://whitepaper.vocdoni.io/" rel="noopener noreferrer" target="_blank">Whitepaper</a></li><li><a href="https://ethresear.ch/t/vocdoni-protocol-enabling-decentralized-voting-for-the-masses-with-zk-technology/21036" rel="noopener noreferrer" target="_blank">Ethresearch thread</a></li><li><a href="https://vocdoni.io" rel="noopener noreferrer" target="_blank">Success stories:</a></li><li class="ql-indent-1"><a href="https://blog.vocdoni.io/new-belarus-vocdoni" rel="noopener noreferrer" target="_blank">New Belarus</a></li><li class="ql-indent-1"><a href="https://thefintechtimes.com/fc-barcelona-reaches-milestone-in-blockchain-tech-adoption-immortalising-johan-cruyff/" rel="noopener noreferrer" target="_blank">Football Club Barcelona</a></li><li class="ql-indent-1"><a href="https://blog.vocdoni.io/referendum-bellpuig" rel="noopener noreferrer" target="_blank">First official digital referendum in Spain</a></li><li class="ql-indent-1"><a href="https://x.com/vocdoni/status/1868017937212162093" rel="noopener noreferrer" target="_blank">One of the biggest political parties in Spain</a></li><li>All our code is opensource and we build in public, you can visit our github repositories here:</li><li class="ql-indent-1"><a href="https://github.com/vocdoni/vocdoni-circuits-artifacts" rel="noopener noreferrer" target="_blank">https://github.com/vocdoni/vocdoni-circuits-artifacts</a></li><li class="ql-indent-1"><a href="https://github.com/vocdoni/circom2gnark" rel="noopener noreferrer" target="_blank">https://github.com/vocdoni/circom2gnark</a></li><li class="ql-indent-1"><a href="https://github.com/vocdoni/davinci-node" rel="noopener noreferrer" target="_blank">https://github.com/vocdoni/davinci-node</a></li><li class="ql-indent-1"><a href="https://github.com/vocdoni/contracts-z" rel="noopener noreferrer" target="_blank">https://github.com/vocdoni/contracts-z</a></li><li class="ql-indent-1"><a href="https://github.com/vocdoni/gnark-crypto-primitives" rel="noopener noreferrer" target="_blank">https://github.com/vocdoni/gnark-crypto-primitives</a></li></ul><h3> </h3><h3>Get Involved</h3>We’re building DAVINCI as an open-source and neutral protocol and invite the Ethereum and governance communities to contribute.

VOCDONI - A public good for secure decentralized voting

Barcelona is more than beaches and Gaudí, it’s becoming a living lab for decentralization. Here, community hubs, open-source software, and grassroots nonprofits join forces to solve real problems: fragile democracies, exclusion, and lack of opportunities for vulnerable groups. This cause highlights Barcelona-based initiatives that prove decentralization is a practical tool for democracy, community, and dignity. They show how technology and solidarity can reinforce each other. Projects in this cause include: Community Hubs<ul><li>Giveth House, a physical hub for Web3 dreamers since 2017, providing space for hack sessions, gatherings, and community building right in the heart of Barcelona.</li><li>Akasha Hub, a decentralized, self-managed space that connects social impact projects with the Ethereum community, hosting free events and local innovators. (This project will be included once verified by Giveth.)</li></ul> Software &amp; Governance Tools<ul><li>Vocdoni &amp; DAVINCI, an open-source voting technology that has already powered elections for city councils, political parties, cooperatives, and even FC Barcelona. Their next step, DAVINCI, brings anonymous, verifiable, anti-coercion voting to DAOs and national elections alike.</li><li>EVMcrispr &amp; ENS Wayback Machine, two open-source tools incubated in the Giveth House. EVMcrispr makes advanced DAO and DeFi operations as simple as UNIX commands; ENS Wayback Machine brings transparency to decentralized web history.</li></ul> Social Impact Organizations<ul><li>Homeless Entrepreneur, a project that leverages civic partnerships and now Web3 philanthropy to help people out of homelessness through work, empowerment, and community.</li><li>Aprenem Autisme, a local NGO supporting autistic children and their families, offering guidance, therapy, and community activities to reduce isolation and stress.</li></ul><h3> </h3><h3>Guiding Principles of this Cause</h3>Barcelona is proving that decentralized infrastructure is not only for finance. The goal is simple but powerful: strengthen democracy, foster inclusion, and prove that decentralized tools can improve lives far beyond finance. Supporting these projects means helping Barcelona show the world how technology and solidarity together can create a lasting impact.
