Os componentes necess\u00e1rios para compilar o navegador Chrome para o sistema operacional Fuchsia foram removidos do reposit\u00f3rio do projeto Chromium. \u00c9 observado que o suporte ao Fuchsia no Chrome era um experimento, agora encerrado. Foi especificado que a raz\u00e3o para o t\u00e9rmino do suporte \u00e9 a suspens\u00e3o do programa de desenvolvimento do Fuchsia para esta\u00e7\u00f5es de trabalho. O suporte aos componentes de navegador WebEngine e WebRunner para o Fuchsia continuar\u00e1, mas um navegador Chrome completo n\u00e3o ser\u00e1 fornecido. Provavelmente, o desenvolvimento futuro do Fuchsia ser\u00e1 focado apenas em dispositivos de consumo, como sistemas de automa\u00e7\u00e3o residencial, molduras inteligentes e alto-falantes. <\/p>\n

O Fuchsia \u00e9 baseado no microkernel Zircon, que se baseia nos desenvolvimentos do projeto LK, ampliado para uso em v\u00e1rias classes de dispositivos, incluindo smartphones e computadores pessoais. O Zircon expande o LK com suporte a processos e bibliotecas compartilhadas, n\u00edvel de usu\u00e1rio, sistema de gerenciamento de objetos e modelo de seguran\u00e7a baseado em capabilities. Os drivers s\u00e3o implementados como bibliotecas din\u00e2micas que operam no espa\u00e7o do usu\u00e1rio, carregadas pelo processo devhost e gerenciadas pelo gerenciador de dispositivos (devmg, Device Manager). <\/p>\n

Para o Fuchsia, foi preparado um gr\u00e1fico interface pr\u00f3prio, escrito na linguagem Dart utilizando o framework Flutter. O projeto tamb\u00e9m desenvolve o framework Peridot para a constru\u00e7\u00e3o de interfaces de usu\u00e1rio, o gerenciador de pacotes Fargo, a biblioteca padr\u00e3o libc, o sistema de renderiza\u00e7\u00e3o Escher, o driver Vulkan Magma, o gerenciador de composi\u00e7\u00e3o Scenic, os sistemas de arquivos MinFS, MemFS, ThinFS (FAT na linguagem Go) e Blobfs, assim como o gerenciador de parti\u00e7\u00f5es FVM. Para o desenvolvimento de aplica\u00e7\u00f5es, suportam-se as linguagens C\/C++, Dart, e nos componentes do sistema \u00e9 permitido o uso de Rust, no stack de rede Go, enquanto na constru\u00e7\u00e3o do sistema, utiliza-se a linguagem Python. <\/p>\n

Durante o processo de inicializa\u00e7\u00e3o, utiliza-se um gerenciador de sistema, que inclui o appmgr para criar o ambiente de programa inicial, sysmgr para configurar o ambiente de inicializa\u00e7\u00e3o e basemgr para definir o ambiente do usu\u00e1rio e organizar o login no sistema. Para garantir a seguran\u00e7a, \u00e9 oferecido um avan\u00e7ado sistema de isolamento sandbox, onde novos processos n\u00e3o t\u00eam acesso aos objetos do kernel, n\u00e3o podem alocar mem\u00f3ria e n\u00e3o podem executar c\u00f3digo, e para acesso a recursos \u00e9 aplicada uma sistema de espa\u00e7os de nome, determinando as permiss\u00f5es dispon\u00edveis. A plataforma fornece um framework para a cria\u00e7\u00e3o de componentes, que s\u00e3o programas que s\u00e3o executados em seu pr\u00f3prio sandbox e podem interagir uns com os outros atrav\u00e9s de IPC.
