Generated using ChatGPT DeepResearch TL;DR: Taiwan’s eID Project (2019–2023) – A Costly Failure Taiwan’s electronic ID (eID) project aimed to replace traditional paper IDs with a chip-based smart card integrating multiple government services. Launched in 2019, it faced immediate criticism over security vulnerabilities, privacy risks, and lack of legal safeguards. Civil society groups, cybersecurity experts, and lawmakers warned that the eID could enable mass surveillance, data breaches, and even foreign interference, especially given reports that key contractors had ties to China. Technical flaws, including a centralized data structure creating a “single point of failure” and potential biometric tracking, raised red flags. Politically, poor public consultation and rushed implementation fueled distrust. By early 2021, local governments refused to participate in trials, and the project was indefinitely suspended by Premier Su Tseng-chang, citing privacy and security concerns. Over NT$1.4 billion was spent on development, but by 2023, the government paid NT$280 million in compensation to contractors, effectively terminating the project. Officials admitted that privacy laws and independent oversight were lacking, and future digital identity efforts would require stronger safeguards. In response, Taiwan is now establishing a Personal Data Protection Commission and shifting towards a “digital ID wallet” model—a smartphone-based system expected by 2025. The failure of the eID project serves as a cautionary lesson on the need for transparency, public trust, and robust legal frameworks before implementing national digital ID systems.

Kevin(host), Vitalik, Sejal, and Devansh https://www.youtube.com/watch?v=ygaEBHYllPU Methodology: Feed Youtube subtitles to ChatGPT Intro Hello and welcome to the Green Pill Network podcast! If you're just joining us, we're building a coordination network society of thousands of hackers, streamers, and doers focused on using crypto to bring positive-sum digital systems to the world. This podcast features the people who are making it happen. If you want to learn more, visit our website at greenpill.network, where you can download the Green Pill book for free, join the Discord, or become a member of your local Green Pill Network chapter. Now, on with the show! This is part two of my special series with Vitalik Buterin about public goods funding at the end of 2025. In part one, we talked about Vitalik's broad view of the design space as we transition from 2024 to 2025, discussing what Builders should focus on. In this second episode of the series, we dive into deepfunding.org, a new experiment that the Gitcoin ecosystem is building with Vitalik's guidance. I should clarify that it's not just Gitcoin but the general public goods funding ecosystem coming together.

Rio Li 發明了一個遊戲： 剛剛開車回家的路上想到了一個類似今際之國方塊或者賭博默示錄的策略遊戲，分享給大家，看有興趣的臉友會不會想到最好的策略 「空頭支票」 遊戲前置： 兩個玩家，分別有兩張紙跟一支筆 遊戲規則 ： （1）兩個玩家一起分別執行，在其中一張紙寫上存單以及一個1-1000之間的整數，並在另外一張紙寫上支票以及一個1-1000之間的整數（兩場紙寫的順序不限），請勿窺視另外一人寫的數字，也努力不要讓另外一人窺視。 （2）雙方確認彼此寫完後，同時揭露兩張紙，並進入提領的程序，如其中一人A寫的支票數字a等於或者小於對方B寫的存單數字b，則A 提領並獲得分數a，B獲得差額分數b-a，而如果A寫的支票數字a大於B寫的存單數字b，則提領失敗，A獲得0分數，B獲得分數b ，雙方誰先提領不限 （3） 雙方結算提領的分數與保留的分數加總為一回合的總分

Thank Onur, Jannik, and Mikerah for the review and the advice published version https://ethresear.ch/t/bls-signatures-in-solidity/7919 [TOC] Who should read this? This article targets developers who want to perform BLS signature verification in Eth1 contracts. For readers interested in the BLS signature in Eth2, I highly recommend "BLS12-381 For The Rest Of Us"^ben-bls by Ben Edgington, which provides long but not too long answers to common questions.

在資料分片的環境底下，我們不能讓全節點去完整下載其他分片上所有的資料，否則就失去分片的意義了。 但我們仍然要顧慮一種情況：某個分片上的惡意節點，發佈了承諾，卻窩藏承諾背後的資料沒有發布。如果說在其他分片上的全節點，都乖乖收下了帶有這個承諾的區塊，這會是個危險的情況。相當於整個系統產出了一個區塊，但區塊上屬於該分片上的資料，除了惡意節點外沒有人知道是什麼。 要解決這個問題可以引入兩個機制：抽樣挑戰和糾刪碼。 抽樣挑戰是我們可以把該分片需要發布的資料切成幾等份，並要求全節點對其抽樣。例如切為 256 份，並對其抽取 75 份。全節點必須在抽樣的 75 份的資料都有正確回應的情況下，才能收下區塊。注意這時候惡意節點的選擇變成到底 256 份的資料中要發布幾份和窩藏幾份。抽樣挑戰的好處是全節點只要少少的抽樣，惡意節點必須發布很大比例的資料（例如 250 份），才能讓全網大部分的全節點完成挑戰並收下區塊。 但發布很大比例的資料仍然不夠，只要惡意節點能夠窩藏一份資料，這區塊就是一個資料不完整的不合格區塊。所以我們除了抽樣挑戰外還需要糾刪碼。

Thanks to Kobi Gurkan and Wanseob Lim for the reviews and the feedback [TOC] We're not talking about "An item purchasable at the Main Shop, under Magical." When I first looked into the zero-knowledge proof applications, the term nullifier confused me a lot. Many projects use nullifiers and define them differently depending on the context. In this post, we review those projects and extract the abstract idea that works for all. A Single-Use Gadget Nullifier is a piece of data that ensures a message only takes effect once. When we see the term nullifier, we can first restrict our attention to this primary function and take care of other details later.
