TLA+ -- формальный язык, предназначенный для спецификации всех видов
компьютерных систем. Системные архитекторы применяют TLA+ для описания
параллельных, распределенных и отказоустойчивых протоколов. Такие системы
обычно описываются на полуформальных языках в виде псевдокода или диаграмм
состояний. Мы применяем TLA+ для описания протоколов в экосистеме блокчейнов
Tendermint/Cosmos.

В первой половине доклада мы рассмотрим принципы спецификации протоколов на
примере протокола обмена криптотокенами в системе Cosmos IBC. На основе примера
показывается подход к итеративной разработке протоколов с применением
верификатора моделей Apalache.

Во второй половине доклада мы рассмотрим принципы работы Apalache. Apalache
транслирует спецификацию на языке TLA+ в систему логических ограничений на
языке SMTLIB и вызывает решатель Z3 для проверки ограничений..

In this video, we will check out flow from Github, install the required dependencies Python, OpenJDK and Haxe, and then compile and run flow programs. We will also install the VS Code extension for flow, and show how to get syntax highlighting, a compile server, and other nice features.
This video shows how to do this for Windows, but the same basic process also works for Linux and Mac.
