Como Configurar Uma Carteira Multi-assinatura

As carteiras com várias assinaturas são contratos inteligentes que exigem o acordo de várias pessoas para realizar uma ação. Eles podem ser úteis para proteger ativos (usando separação de funções) ou para garantir que certas ações sejam tomadas apenas de acordo com os desejos do proprietário da multisig ou da maioria dos proprietários.

Este artigo se concentra em como fazer as melhores escolhas de design ao configurar um multisig e como evitar erros comuns. Veremos demonstrações de várias configurações multisig diferentes. Depois de configurar sua carteira multi-assinatura, você pode adicioná-la ao seu aplicativo .

Por que precisamos de multisigs?

Há muitos casos em que queremos que as ações sejam aprovadas por várias pessoas. Aqui estão alguns exemplos:

Propriedade dividida

Se um ativo pertence a várias pessoas em comum, especialmente um ativo on-chain, um contrato inteligente pode verificar se ele é usado apenas de acordo com os desejos dos proprietários. A blockchain também fornece uma trilha de auditoria que mostra quais proprietários aprovaram qualquer ação, portanto, é impossível para os proprietários fingirem posteriormente que não aprovaram.

Separação de deveres

Mesmo quando um ativo pertence a uma única entidade, as multisigs podem ser úteis para implementar a separação de funções . Quando várias pessoas são obrigadas a aprovar uma ação, tanto a fraude quanto os erros inocentes são muito menos prováveis. Nesses casos, a compensação é entre segurança (mais assinantes significam que você está mais seguro) e velocidade (mais assinantes significam que leva mais tempo para fazer qualquer coisa).

Trilha de auditoria

Há casos em que várias pessoas têm permissão para realizar uma ação, e só queremos saber quem executou a ação. Ao usar um multisig que requer apenas uma assinatura, podemos cobrir esse caso de uso sem os riscos de segurança associados a uma conta compartilhada.

Como funciona um multisig?

Entidades na blockchain, como um contrato multisig, só podem afetar diretamente outras entidades blockchain. As ações que um multisig pode controlar são, portanto, aquelas que podem ser realizadas chamando um contrato inteligente, como a transferência de tokens ERC-20 ou um NFT.

Multisigs têm vários endereços de assinatura que estão autorizados a realizar uma ação, individualmente ou quando aprovados por um grupo de tamanho específico. Cada endereço de assinatura é um endereço Ethereum diferente, normalmente derivado de uma frase de recuperação diferente e de propriedade de uma pessoa diferente. Mais adiante neste artigo, discutiremos as circunstâncias em que você pode querer dar a uma única pessoa o controle de mais de um endereço de assinante.

Tipos de multisigs

A maioria dos multisigs implementa um requisito M-of-N. Isso significa que há um total de N signatários, dos quais M precisa aprovar e assinar antes que a ação ocorra. Isso é chamado de multisig M/N; a razão de M para N é chamada de quorum quorum. Por exemplo, um multisig 3/5 teria cinco signatários, três dos quais precisariam concordar ou aprovar uma ação.

As compensações na configuração dos parâmetros de um multisig se resumem a compensações entre segurança, por um lado, e facilidade e disponibilidade, por outro.

Quanto mais sinalizadores você tiver (N alto) e quanto menos sinalizadores forem necessários (M baixo), mais fácil será encontrar as pessoas necessárias para realizar uma ação
Se você tiver menos signatários (baixo N), a chance de um erro ou um hack total ser aprovado deve ser reduzida
Exigir mais assinantes (M alto) pode se traduzir em mais supervisão e segurança aprimorada, mas se M for muito alto, você terá difusão de responsabilidade ; os principais atores podem presumir que outra pessoa está cuidando se uma aprovação deve ser feita

Demo: Criando uma carteira multisig

Para saber mais sobre o quorum multisig e comparar diferentes casos, vamos criar uma carteira para uma empresa com quatro gerentes. Em nosso exemplo, o multisig precisará ser acessado para alterar uma saudação. Veremos três configurações: sem multisig, 1/3 multisig e 2/4 multisig.

Obviamente, o objetivo deste exemplo é simplesmente demonstrar o multisig, não o contrato que ele controla. Em aplicações do mundo real, os contratos geralmente executam funções mais valiosas do que alterar uma saudação e geralmente limitam o número de indivíduos que podem fazer uma alteração.

Sem multiassinatura

Antes de chegarmos ao multisig, devemos configurar nosso ambiente de laboratório e o contrato de destino (o contrato que o multisig controla). O ambiente de laboratório é executado em cima da rede de teste Goerli . Se você precisar de Goerli test ETH, você pode obtê-lo nesta torneira .

Para nossa demonstração, usaremos um contrato inteligente simples chamado Greeter.sol , que implantei com o Hardhat . Você pode vê-lo aqui .

Para ver a saudação atual, abra Contrato > Ler contrato e expanda saudação .

Para modificar a saudação atual, abra Contrato > Gravar contrato . Em seguida, clique em Conectar ao Web3 para conectar-se à carteira. Depois de selecionar uma carteira das opções listadas, clique em setGreeting e digite a nova saudação. Em seguida, clique em Escrever e aprove o contrato na carteira.

Observe que, devido ao armazenamento em cache, depois de alterar a saudação, pode ser necessário recarregar o contrato algumas vezes antes de poder ver a nova saudação.

1/4 multisig (é necessária uma assinatura)

A demo multisig foi criada com Gnosis Safe , que é provavelmente a plataforma multisig mais comum.

Os endereços que estão autorizados a usar o multisig são todos derivados da senha: “dumb cart rally entry iron band man demise record moon erode green”

Os endereços são os seguintes:

0x3646468082813B33BF7aab1b8333Aa01fEe8a386
0x8c262b009B05e94D3ffF1Ce4cEa8Da0ba450c793
0x126FE1acDB5A5101B80Dc68A0b0dc882BFeEe5A6
0x0C48dfb3FAaFBCECF21f0D1F4e75E1fE6e731Ad6
0x934003bC77b9D427c4a441eBef2086AA089Ed0C5
0x9D5f666b29D0dd2397fDbc093fdaCAa0EF6e7377

Em cenários do mundo real, os endereços vêm de senhas exclusivas quando pertencem a pessoas diferentes. No entanto, fazer isso aqui exigiria que você (como leitor) saísse continuamente de uma senha e entrasse em outra ou usasse vários dispositivos. Para este treinamento, decidi que a conveniência supera a segurança, portanto, omitiremos as senhas exclusivas nesta demonstração.

Agora, vejamos um exemplo em que apenas os proprietários podem alterar a saudação. Neste exemplo, apenas uma assinatura é necessária para fazer uma alteração.

Vamos usar o mesmo Greeter.solcontrato. Em um aplicativo do mundo real, provavelmente implementaríamos Ownablee definiríamos o proprietário como multisig, mas o objetivo aqui é tornar as coisas o mais simples possível, não tão seguras quanto possível.

Quando um único signatário é necessário, você precisa propor e confirmar a transação.

Navegue aqui com um navegador que tenha uma carteira com a senha especificada acima e conecte-se a um dos quatro primeiros endereços listados acima
Clique em Nova transação e interação do contrato
Cole o endereço do contrato com o qual você está tentando interagir:0x8A470A36a1BDE8B18949599a061892f6B2c4fFAb
Observe que a ABI com as definições de como entrar em contato com o contrato é importada automaticamente; o código do contrato está disponível no Etherscan, então o Gnosis Safe pode recuperar o código
Selecione o setGreetingmétodo e digite uma nova saudação
Clique em Revisar e Enviar ; em seguida, aprove a transação na carteira
Espere
Depois que a transação for executada, vá para o contrato e expanda saudação para ver que a saudação foi alterada

2/4 multisig (duas assinaturas necessárias)

A seguir, vejamos um exemplo em que dois dos quatro proprietários devem assinar. Para esta demonstração, precisaremos fingir ser um segundo gerente e aprovar a transação para ter as duas assinaturas necessárias para que a transação ocorra.

Primeiro, siga as etapas do exemplo anterior, mas use este arquivo .

Mude para um endereço diferente na carteira (um dos outros três aprovadores)
Navegue aqui novamente; talvez seja necessário desconectar e reconectar no aplicativo para que o endereço correto apareça
Clique na transação em Fila de transações
Expanda a transação, clique em Confirmar para aprovar a transação e clique em Enviar
Aprovar a transação na carteira

Agora, visualize a transação e verifique se a ação solicitada ocorreu (se a saudação realmente mudou):

Navegue aqui e expanda saudação para ver que a saudação realmente mudou
Para ver a transação, clique em Internal Txns e localize a transação mais recente entre o multisig (0x8f760d2fd9999d407b3c4b67555bf037ed5eb832) e o saudador (0x8a470a36a1bde8b18949599a061892f6b2c4ffab)
Clique em Parent Txn Hash para ver a transação que alterou a saudação
Observe que o segundo signatário está listado como a origem

Problemas potenciais com multisigs

As carteiras Multisig destinam-se a fornecer segurança adicional, mas ainda podem surgir problemas. Vejamos alguns exemplos.

Recursos bloqueados

A grande vantagem do blockchain é que não há uma autoridade central. No exemplo acima, ninguém pode aprovar uma transação do multisig, exceto pelo menos dois desses quatro endereços de gerente.

A grande desvantagem do blockchain é que não há uma autoridade central para substituir os contratos nos momentos em que isso se justifica. Por exemplo, no caso da morte de três signatários de um multisig 2/4, não haveria como o multisig liberar nenhum de seus ativos. Os ativos da carteira permaneceriam bloqueados para sempre.

Uma opção para fornecer um backup para esse tipo de cenário é fazer com que alguém em quem a empresa confie completamente (por exemplo, o proprietário) gere dois endereços adicionais e armazene suas senhas em envelopes invioláveis em um local seguro. Um local fora do local, como o cofre do advogado ou da conta da empresa, geralmente é uma boa opção.

Substituição do proprietário

Em um multisig, todos os signatários são iguais. O problema é que às vezes queremos signatários mais iguais que os outros. Por exemplo, podemos querer que os gerentes de negócios possam fazer algo com uma assinatura adicional, mas que o proprietário possa fazer qualquer coisa.

Uma solução seria permitir que o endereço do proprietário acesse o contrato de destino diretamente, sem passar pelo multisig. Esta solução tem a melhor usabilidade, mas significa que não podemos confiar totalmente no multisig para auditoria.

Uma segunda opção é o proprietário gerar dois endereços a partir da senha e usar os dois endereços como signatários. Esta solução tem usabilidade mais limitada, mas pode ser uma opção melhor se parte do propósito do multisig for reduzir a chance de um erro por descuido e se as substituições do proprietário forem usadas como uma medida de emergência, em vez de parte do processamento diário.

Demo: Criando uma carteira multisig compartilhada

Agora, vejamos um cenário mais complexo, em que duas empresas colaboram e a função da carteira exige a aprovação de pelo menos um gerente de cada empresa.

Como todos os signatários são iguais em um multisig, precisamos escrever alguma lógica no contrato para atingir esse objetivo. Clique aqui para ver o contrato Solidity .

Vamos ver o que acontece quando a empresa A propõe uma nova saudação.

Vá para o contrato e verifique a saudação atual
Mude a carteira para um dos endereços do grupo A:
- 0x3646468082813B33BF7aab1b8333Aa01fEe8a386
- 0x8c262b009B05e94D3ffF1Ce4cEa8Da0ba450c793
- 0x126FE1acDB5A5101B80Dc68A0b0dc882BFeEe5A6
Navegue até o grupo A multisig
Clique em Nova transação > Interação do contrato
Digite o endereço do contrato:0x3e55E2DBDE169Fbf91B17e337343D55a7E0D728e
Clique em proporGreetingA e proponha uma saudação
Clique em Revisar e depois em Enviar
Confirme a transação na carteira
Vá para o contrato novamente e veja que a saudação não foi alterada

A seguir, vamos ver o que acontece quando a empresa B propõe uma saudação diferente. Essa etapa é necessária porque não basta ver que o contrato inteligente se comporta corretamente quando as pessoas seguem os procedimentos adequados. É igualmente importante garantir que o contrato permaneça seguro quando as pessoas não seguem um procedimento adequado.

Mude a carteira para um dos endereços do grupo B:
- 0x0C48dfb3FAaFBCECF21f0D1F4e75E1fE6e731Ad6
- 0x934003bC77b9D427c4a441eBef2086AA089Ed0C5
- 0x9D5f666b29D0dd2397fDbc093fdaCAa0EF6e7377
Navegue até o grupo B multisig
Clique em Nova transação > Interação do contrato
Digite o endereço do contrato:0x3e55E2DBDE169Fbf91B17e337343D55a7E0D728e
Clique em proporGreetingA e proponha uma saudação
Veja se a revisão informa que a transação falhará (porque você não é membro do grupo correto); clique em Voltar
Selecione a opção adequada para seu endereço atual, propGreetingB , e proponha uma saudação (certifique-se de selecionar uma saudação diferente daquela proposta pela empresa A)
Clique em Revisar e depois em Enviar
Confirme a transação na carteira
Vá para o contrato novamente e veja que a saudação ainda não foi alterada

Agora, vamos ver o que acontece quando a empresa B propõe a mesma saudação que foi proposta pela empresa A.

Tente proporGreetingB novamente, desta vez com a mesma saudação que você propôs como membro do grupo A
Volte ao contrato, pela última vez, e veja se a saudação finalmente mudou

Vamos dar uma olhada no código do Solidity para ver como isso funciona:

/**
 *Submitted for verification at Etherscan.io on 2022-05-08
*/

//SPDX-License-Identifier: Unlicense
pragma solidity ^0.8.0;


contract AB_Greeter {
  string greeting;

Aqui estão os endereços dos multisigs:

  address multisigA;
  address multisigB;

Essas variáveis contêm os hashes das saudações propostas.

Usar os hashes tem duas vantagens.

O armazenamento Ethereum é um recurso caro, dessa forma usamos menos
Quando armazenamos o hash só precisamos escrever uma palavra de 32 bytes por proposta

Se tivéssemos que armazenar cordas, elas poderiam ser muito mais longas e mais caras. Além disso, o Solidity não possui uma expressão embutida para comparar strings, portanto, a maneira mais fácil de comparar duas strings é comparar seus hashes. Usando hashes, calculamos o hash apenas uma vez para cada vez que chamamos proposeGreeting[AB].

  bytes32 proposedGreetingA = 0;
  bytes32 proposedGreetingB = 0;

Para começar, precisamos da saudação, bem como dos endereços dos dois multisigs:

  constructor(string memory _greeting, 
              address _multisigA, 
              address _multisigB) {
    greeting = _greeting;
    multisigA = _multisigA;
    multisigB = _multisigB;
  }

As funções greete setGreetingsão as mesmas do Greeter.solcontrato que usamos anteriormente.

  function greet() public view returns (string memory) {
    return greeting;
  }

  function setGreeting(string memory _greeting) internal {
    greeting = _greeting;
  }

Esta é a função de propor uma nova saudação.

  function proposeGreetingA(string calldata _greeting) public {

Só multisigAé permitido propor saudações como empresa A; qualquer outra fonte será rejeitada.

    require(msg.sender == multisigA, "Only for use by multisig A");
    bytes32 _hashedProposal = keccak256(abi.encode(_greeting));

Se a empresa B já propôs o que a empresa A está propondo agora, atualizamos a saudação assim:

    if(_hashedProposal == proposedGreetingB)    
      setGreeting(_greeting);

Caso contrário, registramos isso como saudação proposta pela empresa A:

    else
      proposedGreetingA = _hashedProposal;
  }

É importante perceber que essa não é a maneira ideal de atingir esse objetivo porque multisigAé 1/3, portanto, qualquer um dos gerentes da empresa A poderia mudar o multisig e tirar a capacidade dos outros dois signatários de propor ou aprovar qualquer coisa.

Uma política mais sensata seria ter outro multisig, talvez um 2/3, para esse tipo de operação sensível. No entanto, o objetivo deste exemplo é ensinar, então vamos optar pela simplicidade sobre a segurança.

No código abaixo especificamos que multisigApode mudar para um novo multisig se isso for necessário.

  function changeMultisigA(address _newMultiA) public {
    require(msg.sender == multisigA, "Only for use by multisig A");    
    multisigA = _newMultiA;
  }

As funções da empresa B são a imagem espelhada das da empresa A.

 function proposeGreetingB(string calldata _greeting) public {
    .
    .
    .
  }

  function changeMultisigB(address _newMultiB) public {
    .
    .
    .
  }
}

Aviso sobre o desenvolvimento de contratos inteligentes

O desenvolvimento de contratos inteligentes é relativamente fácil, mas o desenvolvimento seguro de contratos inteligentes não é. A menos que você tenha muita experiência em segurança, é altamente recomendável que alguém com conhecimento revise sua lógica e código antes de confiar em um aplicativo de missão crítica.

Por exemplo, quando escrevi o AB_Greetercontrato, primeiro usei apenas uma única variável para a saudação proposta e meu código ficou assim:

  function proposeGreetingA(string calldata _greeting) public {
    require(msg.sender == multisigA, "Only for use by multisig A");
    bytes32 _hashedProposal = keccak256(abi.encode(_greeting));

    if(_hashedProposal == proposedGreeting) {
      setGreeting(_greeting);
    } else {
      proposedGreeting = _hashedProposal;
    }
  }

Você consegue identificar o problema?

De fato, são necessárias duas aprovações para alterar a saudação. No entanto, a empresa A pode ligar proposeGreetingAduas vezes com a mesma saudação. A primeira chamada coloca o hash da nova saudação como proposta. A segunda chamada vê que o hash da nova saudação é idêntico à proposta e atualiza a saudação.

Se a proposta tivesse vindo da empresa B, tudo bem, mas aqui a proposta veio da empresa A, então isso é uma violação dos termos.

Para resolver essa questão, decidi utilizar duas propostas distintas, uma sob controle da empresa A e outra sob o controle da empresa B.

Não estou dizendo que a lógica do contrato atual é 100% segura. Se eu fosse usar isso em produção, pediria a outras pessoas para olharem primeiro. Os contratos inteligentes existem para permitir a cooperação sem confiança. Ao escrevê-los, você deve assumir que eles serão usados em um ambiente hostil. A despesa de executar um contrato inteligente em vez de um programa mais convencional só se justifica se o ambiente for potencialmente hostil.

Conclusão (quando multisigs é a solução certa?)

Multisigs são uma solução simples para um problema simples – como obter permissões de um grupo quando todos os membros do grupo são iguais e a associação do grupo raramente muda.

Neste artigo, revisamos alguns mecanismos para estender essa funcionalidade, seja usando o multisig de maneira incomum (o proprietário com dois signatários) ou adicionando nossa própria lógica em um contrato inteligente separado (o cenário de duas empresas).

Se sua população de assinantes for dinâmica ou se você tiver muitas funções diferentes, cada uma com suas próprias permissões, um multisig pode não ser a solução ideal. Em vez disso, uma organização autônoma descentralizada pode ser uma opção melhor.

No entanto, se os requisitos de negócios que você precisa implementar forem tais que um multisig seja suficiente, essa é uma solução muito mais simples do que criar um DAO. Observe em nosso primeiro exemplo que não precisamos escrever nenhum código. Você também pode integrar multisigs em seus próprios aplicativos usando o SDK .

Multi-cloud Spending: 8 Tips To Lower Cost

A multi-cloud approach is nothing but leveraging two or more cloud platforms for meeting the various business requirements of an enterprise. The multi-cloud IT environment incorporates different clouds from multiple vendors and negates the dependence on a single public cloud service provider. Thus enterprises can choose specific services from multiple public clouds and reap the benefits of each.

Given its affordability and agility, most enterprises opt for a multi-cloud approach in cloud computing now. A 2018 survey on the public cloud services market points out that 81% of the respondents use services from two or more providers. Subsequently, the cloud computing services market has reported incredible growth in recent times. The worldwide public cloud services market is all set to reach $500 billion in the next four years, according to IDC.

By choosing multi-cloud solutions strategically, enterprises can optimize the benefits of cloud computing and aim for some key competitive advantages. They can avoid the lengthy and cumbersome processes involved in buying, installing and testing high-priced systems. The IaaS and PaaS solutions have become a windfall for the enterprise’s budget as it does not incur huge up-front capital expenditure.

However, cost optimization is still a challenge while facilitating a multi-cloud environment and a large number of enterprises end up overpaying with or without realizing it. The below-mentioned tips would help you ensure the money is spent wisely on cloud computing services.

Deactivate underused or unattached resources

Most organizations tend to get wrong with simple things which turn out to be the root cause for needless spending and resource wastage. The first step to cost optimization in your cloud strategy is to identify underutilized resources that you have been paying for.

Enterprises often continue to pay for resources that have been purchased earlier but are no longer useful. Identifying such unused and unattached resources and deactivating it on a regular basis brings you one step closer to cost optimization. If needed, you can deploy automated cloud management tools that are largely helpful in providing the analytics needed to optimize the cloud spending and cut costs on an ongoing basis.

Figure out idle instances

Another key cost optimization strategy is to identify the idle computing instances and consolidate them into fewer instances. An idle computing instance may require a CPU utilization level of 1-5%, but you may be billed by the service provider for 100% for the same instance.

Every enterprise will have such non-production instances that constitute unnecessary storage space and lead to overpaying. Re-evaluating your resource allocations regularly and removing unnecessary storage may help you save money significantly. Resource allocation is not only a matter of CPU and memory but also it is linked to the storage, network, and various other factors.

Deploy monitoring mechanisms

The key to efficient cost reduction in cloud computing technology lies in proactive monitoring. A comprehensive view of the cloud usage helps enterprises to monitor and minimize unnecessary spending. You can make use of various mechanisms for monitoring computing demand.

For instance, you can use a heatmap to understand the highs and lows in computing visually. This heat map indicates the start and stop times which in turn lead to reduced costs. You can also deploy automated tools that help organizations to schedule instances to start and stop. By following a heatmap, you can understand whether it is safe to shut down servers on holidays or weekends.
