Сейчас 10 лет Яндекс.Такси. Кажется, именно Яндекс первым привел Uber-модель в Россию. Пишут, что мой первый заказ был в мае 2013-го. Целая вечность назад, но я помню — был где-то в районе Лесной, нужно было в точку, удалённую от метро. Как раз крутили рекламу нового сервиса от Яндекса, я скачал, запустил поиск. Ждал минут 15, потом ещё искал, где водитель припарковался. Быстрее было бы дойти.
Сейчас уже стало ясно, что сервисы такси — одна из важнейших технологических вех нового времени. Сложно представить себе что-то ещё, что настолько фундаментально поменяло наши жизни. Ни роботы-пылесосы, ни сервисы доставки, ни даже каршеринг — ничто из этого настолько сильно не поделило мир на "до" и "после". Процесс вызова такси по телефону действительно был неприлично труден: следовало знать адрес, где находишься, знать номер таксопарка, а затем ждать неопределенное время, после чего платить весьма немалые деньги водителю налом. К такси прибегали в крайних случаях, когда обойтись другим способом было невозможно.
Сокращение такого значительного числа издержек в столь необходимой для людей услуге — перемещение — сопоставимо с изобретением интернета или электричества. Да, и без электричества мы могли обогревать и освещать свои дома, готовить пищу, вращать мельницы. Но на этом примере становится видно, что время и усилия на получение результата очень важны. Такси стало полноценным вариантом повседневного транспорта, а не редкой вынужденной мерой для богатых. Я заказываю такси десяток раз в месяц, и уже всерьез не способен вспомнить, как в принципе возможно было жить без этих сервисов. Что я делал в таких же ситуациях 10 лет назад? Ждал автобус полчаса, шел пешком час? Или даже просто отменял своё намерение добраться в какую-то точку? Лучше, наверное, и не вспоминать.

🚀 StarkWare Researcher Proposes Complex Bitcoin Transaction Scheme
StarkWare researcher Avihu Mordechai Levy has introduced a Bitcoin transaction scheme that aims to circumvent the need for a protocol change. According to NS3.AI, the proposed method involves solving a pre-broadcast puzzle, which would necessitate approximately 70 trillion attempts. Levy characterized this design as a last-resort solution due to its significant computational demands, large transaction size, and potential relay-policy challenges, all of which could hinder scalability.

🚀 Zcash Open Development Lab Unveils Strategic Direction Focused on Post-Quantum Security
On April 13, Zcash Open Development Lab (ZODL) founder Josh Swihart announced the latest developments for Zcash, emphasizing a strategic direction centered on post-quantum security, scalability, and user experience. According to BlockBeats, Swihart likened the initiative to the Artemis II lunar mission, highlighting the pursuit of seemingly impossible goals through technological breakthroughs. The ZODL team revealed that Zcash is entering the 'Zcash IV' phase, aiming to build infrastructure akin to a 'lunar base' to support the protocol and applications' secure expansion to billions of users, while advancing the vision of privacy transactions without large-scale financial surveillance.
On the product and technology front, ZODL continues to iterate, with its 3.3.x version now available on iOS and Android, featuring new hardware wallet connection management, SDK upgrades, and multiple user experience enhancements. Key developments include advancing Keystone wallet functionality and upgrading the address system (ZIP 316, UIVK/UFVK). Meanwhile, the Zcash core team has addressed several system issues and is progressing with the Zallet alpha version development, strengthening unified address standards and wallet interaction experience to lay the foundation for future scalability and performance improvements.
Additionally, ZODL disclosed ongoing growth in application data and participation in a stablecoin privacy summit to enhance industry collaboration. However, due to increased regulatory and network restrictions, ZODL has temporarily removed its app from Russian app stores. The team emphasized that privacy is not optional but a fundamental need in the digital age, and they will continue to accelerate delivery pace to promote ZEC adoption and ecosystem development.
The core of Zcash Open Development Lab is to develop an open, self-custodial private financial platform, aiming to expand ecosystem interoperability through collaboration and bring protected ZEC transactions to the global mainstream market.
