В книге и фильме «Чарли и шоколадная фабрика» владелец фабрики Вилли Вонка решает найти себе преемника, поэтому приглашает нескольких детей на экскурсию, где они подвергаются разного рода проверкам на соответствие нужным человеческим качествам: отсутствие жадности, эгоизма, честолюбия, гордыни итд.
Но есть проблема. Изначально дети должны были быть выбраны случайно: в выпускаемых фабрикой шоколадках спрятали 5 билетов. Но по факту такой способ как раз приводит к отбору наиболее нерелевантных кандидатов: один билет получает мальчик-обжора из-за того, что ест слишком много шоколада, другой билет попадает к избалованной дочке миллиардера, потому что он просто покупает ей очень много пачек, третий достается самовлюблённой тщеславной спортсменке, помешанной на победах по всём, четвертый вычисляет геймер, который не любит шоколад.
На мой взгляд это хорошая задачка для собеседования HR-специалисту: каждая итерация отбора должна приближать выборку к цели, а не отдалять. Что мог сделать Вонка, чтобы изначально к нему попала пятерка добрых и честных детей?
Второй важный момент это разница между гипотетическим и реальным функционированием той или иной системы. Такого в жизни очень много: например, в голосованиях на каких-нибудь конкурсах теоретически предполагается, что люди не будут накручивать, а ПДД не предполагают, что на слишком широкой полосе люди будут ехать в два ряда абсолютно всегда (см. Выборгское шоссе). Бюрократия так вообще вся построена на отрицании реальности, что приводит, например, к существованию понятия «Итальянская забастовка».
Считаю, что способность адекватно дозировать формализм с поправкой на реальность это ценное свойство, например, для руководителя.

🚀 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.
