INTRODUCTION

English translation pending.

CORE DEFINITION

A technique from computer architecture in which the processor stays in a low-power state and accumulates pending interrupts, waking once to handle them together instead of servicing each request immediately. Its core proposition is that batching scattered interruptions into fixed windows preserves long stretches of focused attention and removes the context-switching cost of responding as each message arrives. The qualifier is that genuinely urgent items must bypass the batching rule, otherwise the delay defeats the purpose.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

- Window setting: fix two daily windows in which all messages and approvals are handled. - Silent default: stay in a focused and unreachable state outside those windows. - Urgency exception: define in advance what may interrupt the batching rule and what may not.

Anchor fast decisions

Handling every message as it arrives forces a context switch each time, and the cost of reloading the working state is paid repeatedly. Batching the requests into fixed windows removes most of those switches, so the processor and the person stay in one state for long stretches, which is what preserves the deep work that frequent interruption destroys.

The Pomodoro Technique

The Pomodoro Technique is a time management method developed by Francesco Cirillo in the 1980s. The technique uses a timer to break down work into intervals, traditionally 25 minutes in length, separated by short breaks. These intervals are named pomodoros, the Italian word for 'tomato'.

Zero-Knowledge Proof

In cryptography, a zero-knowledge proof or zero-knowledge protocol is a method by which one party (the prover) can prove to another party (the verifier) that a given statement is true, without conveying any information apart from the fact that the statement is indeed true. Thus, it can be understood as a 'zero-leakage proof'.
