But what are they, exactly?Simply put, smart contracts are tiny programs that run on a blockchain and automatically execute when certain conditions are met. They can be used to facilitate transactions between two or more parties without the need for a third party to mediate the transaction. Table of Contents<pre>How do smart contracts work? ⚙️

Risks and downsides ⚠</pre><h3>How do smart contracts work? ⚙️</h3>Smart contracts are a critical component of the decentralized web 3.0 ecosystem, as they provide a way for two or more parties to facilitate transactions without needing a mediator or other third party to oversee and verify the transaction.At their core, smart contracts are simple programs that run on a blockchain network. These programs contain statements that define specific conditions, or "if/then" statements, for example. When certain conditions are met, the program will automatically execute the associated task or function.This unique property of smart contracts makes them ideal for a wide range of applications and use cases, from home sales to financial transactions to supply chain management. Because they run on a blockchain network, these contracts are also immutable, meaning they cannot be tampered with or altered once they have been created. In this way, smart contracts provide a secure and highly reliable means of automating transactions between multiple parties.As the popularity of blockchain technology grows, so too does the potential for smart contracts to revolutionize many areas of our economy and society.Furthermore, smart contracts are distributed via blockchain. It means that every node in a blockchain network validates the contract output. As a result, no one can force the contract to release funds because the nodes will detect such an attempt and mark it as invalid.<blockquote>👉 Smart Contracts 101: Farewell outdated middlemen!</blockquote> <h3>Do all smart contracts run on Ethereum?</h3>Although Ethereum is the most popular platform for creating smart contracts, there are others that provide the same security and efficiency, including <a href="http://solana.com/" target="_blank">Solana</a>, <a href="https://cardano.org/" target="_blank">Cardano</a>, <a href="https://decrypt.co/resources/cosmos" target="_blank">Cosmos</a>, <a href="https://decrypt.co/resources/hyperledger" target="_blank">Hyperledger</a> and <a href="http://binance.com/" target="_blank">BNB chain</a>.Regardless, keep in mind that Ethereum smart contracts are public and can be viewed as open APIs. This means that users can use other smart contracts, broadening their options for creating new ones. <h4>A tip if you want to write your own smart contract</h4>With <a href="https://dappkit.dev/" target="_blank">dappKit</a>, you can start building your own smart contracts. It is a free and open-source web3 SDK that enables developers to create web3 applications and products.What's most fascinating about dappkit is that developers don't need to start coding from scratch. This simplifies development down to only three lines of code. Also, the dappKit transpiler allows developers to generate a typescript/javascript SDK for custom smart contracts.<blockquote>👉 Learn more about dappKit</blockquote><h3> </h3><h3>Smart Contracts Benefits 🎉</h3>Smart contracts can be used for a variety of purposes other than sales. They are used in supply chains, object registration, and fund release, among other things, as we will see later in this article.This flexibility is one of the most significant benefits of smart contracts, and it is one of the reasons why they are increasingly being used by a variety of industries, which are paying close attention to the following smart contract benefits:<ul><li>Trust and Transparency: Once all terms and transactions are visible and accessible, and no third party is involved, no one can change the agreements for personal gain.</li><li>Security: Because blockchain is the most secure way to encrypt data, smart contracts are virtually impossible to hack. Remember that each record is linked to a chain of nodes, so to defraud the contract, a malicious person would need to hack the entire chain.</li><li>Accuracy and efficiency: when a predetermined condition occurs, the contract is automatically executed, and all terms are saved and recorded explicitly.</li><li>Guaranteed Outcomes: Because of the benefits mentioned above, smart contracts are quick while also not raising questions. Contracts that self-execute significantly reduce the need for litigation.</li></ul><blockquote>👉 <a href="https://taikai.network/en/blog/cefi-vs-defi" target="_blank">CeFi vs DeFi</a>: what you need to know</blockquote><h3> </h3><h3>Applications of smart contracts ✏️</h3>Smart contracts can be used for more than transactions- they have different applications in various industries. For example, banks could use smart contracts for loans and automatic payments. Also, insurance DAOs are already taking advantage of smart contracts to handle certain claims. The community of the DAO would need to approve the insurance claim before it is given out, similar to how a board or commission approves a request.Furthermore, smart contracts can also be used in crowdfunding, for example, when people bring money to a project and, if the project manager fails to meet the goal, the money is automatically returned.Let's look at some smart contract examples and some case studies to see how they work in practice. <h4>Supply Chain Management</h4>There are four entities in a supply chain management flow: a manufacturer, a supplier, a retailer, and customers.Smart contracts may improve efficiency, speed and reduce disruptions to this process. Farmers, for example, could enter their food details on smart contracts, such as origination, crop type, and storage information, using blockchain, so that the information stored is accessible to all involved stakeholders.Following that, food processing companies can bid on crops using the smart contract, and once a bid is accepted, they enter refining information on the blockchain.The following step is for processing companies to transport the food to wholesalers, update transportation details on the blockchain, and wholesalers to begin bidding via the smart contract.Finally, the end consumer tracing the food items from the supply chain blockchain can ensure that every piece of information captured on the smart contract is accurate.In other words, since the rules are incorporated into the smart contracts, food compliance is maintained at all stages of processing. This assists consumers in determining quality and origin. <h4>Trade</h4>Smart contracts provide a secure decentralized platform that ensures accountability, transparency, and traceability when conducting trade operations.For example, IBM Blockchain has created <a href="https://we-trade.com/" target="_blank">we.trade</a> with the goal of creating a trustworthy ecosystem for trade with standardized rules and simplified trading options. The goal is to reduce trading friction and risk while also streamlining information exchange and increasing trading opportunities for all participants, such as businesses and banks. <h4>Insurance claims</h4>In general, insurance companies suffer from poor communication among parties, which presents an opportunity to build smart contracts in this industry instead of cumbersome paper contracts. Furthermore, smart contracts significantly reduce the likelihood of cheating and making false claims to receive payouts.With no third party involved, there is no room for manipulation on either side thanks to algorithms in smart insurance code that can eliminate administrative hurdles, predetermine payout scenarios, and execute contract conditions. In a recent smart contracts example, <a href="https://intellias.com/smart-contract-solution-vehicle-insurance/" target="_blank">Intellias</a> developed a web app to enable online vehicle insurance policy purchases for insurance providers in Europe, as part of a smart contract solution. As a result, the insurance company gained access to a suite of highly scalable smart contract solutions. The prototype can electronically insure vehicles, manage auto insurance history, and submit auto insurance claims automatically. <h3>Smart contracts risks and downsides ⚠</h3>Smart contracts are a highly secure method of making contracts between all parties involved. However, users should be aware of some smart contract risks and drawbacks, such as immutability, confidentiality, external data, and legal issues.Let us clarify:Immutability is one of the main challenges. The protocol rules cannot be changed once they are established on the blockchain.While this increases security against fraud, it also makes smart contracts more difficult to use. Furthermore, the immutability of the code makes it nearly impossible to fix bugs.External data issues are another disadvantage of smart contracts because blockchains rarely communicate outside the network.To solve it, developers must use oracles, which are applications that retrieve data from the outside world.Confidentiality is one of smart contract risks, because blockchain makes all node activity information related to transactions available.So, if you don’t want confidential information about your contract to be available, maybe you should think twice: blockchain applications can be tampered with by malevolent users to reveal the state of the contract.Legal issues are another concern since lawyers are not required while using smart contracts. Besides that, if you later take some discussion to court, it is unlikely that it will be used as evidence because most countries do not consider smart contracts to be legal under their laws. <h3>Final thoughts 🔮</h3>Smart contracts are unique in that they can be executed automatically on a blockchain when predetermined conditions are met, without the need for third parties. There are already some good examples of smart contracts being used across industries such as supply chain, trade and insurance models. Sweden has already utilized smart contracts to establish land ownership via a blockchain-based land register, which could pave the way for other government smart contract use cases. create new possibilities for how real estate is bought, sold, and managed – from streamlining paperwork to creating trusted Land Records repositories. Another example is the winner of <a href="https://taikai.network/br/startuplisboa/hackathons/hackathome" target="_blank">HACKATHOME</a>, a real estate hackathon held in Lisbon and hosted by <a href="https://taikai.network/en/hackathons" target="_blank">TAIKAI</a>, who developed a project that uses smart contracts to connect property owners, investors, and curators (such as architects).Despite the challenges smart contracts face, there is no doubt that the future looks bright. As more businesses and industries begin to adopt blockchain technology, the demand for smart contracts is likely to grow. As such, developers and programmers will need to continue working to improve and refine the technology in order to ensure that it remains secure and reliable. Ultimately, this will be essential for the widespread adoption of smart contracts by businesses and consumers alike. <h3>Explore smart contracts through hackathons!</h3>TAIKAI is a hackathon platform that connects companies with talented developers to create solutions.

Esses programas cont&ecirc;m declara&ccedil;&otilde;es que definem condi&ccedil;&otilde;es espec&iacute;ficas, como declara&ccedil;&otilde;es &quot;se/ent&atilde;o&quot;, por exemplo.Quando certas condi&ccedil;&otilde;es s&atilde;o atendidas, o programa executar&aacute; automaticamente a tarefa ou fun&ccedil;&atilde;o associada.Essa propriedade &uacute;nica dos smart contracts os torna ideais para uma ampla variedade de aplica&ccedil;&otilde;es e casos de uso, desde vendas de im&oacute;veis at&eacute; transa&ccedil;&otilde;es financeiras e gerenciamento da cadeia de suprimentos.Por serem executados em uma rede blockchain, esses contratos tamb&eacute;m s&atilde;o imut&aacute;veis, ou seja, n&atilde;o podem ser adulterados ou alterados ap&oacute;s sua cria&ccedil;&atilde;o. Dessa forma, os smart contracts fornecem um meio seguro e altamente confi&aacute;vel de automatizar transa&ccedil;&otilde;es entre v&aacute;rias partes.&Agrave; medida que a popularidade da tecnologia blockchain cresce, tamb&eacute;m aumenta o potencial dos smart contracts&nbsp;para revolucionar muitas &aacute;reas de nossa economia e sociedade.Al&eacute;m disso, os smart contracts s&atilde;o distribu&iacute;dos por meio da blockchain. Isso significa que cada node em uma rede blockchain valida a sa&iacute;da do contrato. Como resultado, ningu&eacute;m pode for&ccedil;ar o contrato a liberar fundos, pois os n&oacute;s detectar&atilde;o tal tentativa e a marcar&atilde;o como inv&aacute;lida.<blockquote>👉 Smart Contracts 101: Adeus intermedi&aacute;rios desatualizados!</blockquote><h3>Todos os contratos inteligentes s&atilde;o executados no Ethereum?</h3>Embora o Ethereum seja a plataforma mais popular para a cria&ccedil;&atilde;o de smart contracts, existem outras que oferecem a mesma seguran&ccedil;a e efici&ecirc;ncia, incluindo <a href="http://solana.com/" rel="noopener noreferrer" target="_blank">Solana</a>, <a href="https://cardano.org/" rel="noopener noreferrer" target="_blank">Cardano</a>, <a href="https://decrypt.co/resources/cosmos" rel="noopener noreferrer" target="_blank">Cosmos</a>, <a href="https://decrypt.co/resources/hyperledger" rel="noopener noreferrer" target="_blank">Hyperledger</a> e <a href="http://binance.com/" rel="noopener noreferrer" target="_blank">BNB Chain</a>.Independentemente disso, tenha em mente que os smart contracts do Ethereum s&atilde;o p&uacute;blicos e podem ser vistos como APIs abertas.Isso significa que os usu&aacute;rios podem utilizar outros smart contracts, ampliando suas op&ccedil;&otilde;es para a cria&ccedil;&atilde;o de novos contratos.<h3>Uma dica se voc&ecirc; deseja escrever seu pr&oacute;prio smart contract</h3>Com o <a href="https://dappkit.dev/" rel="noopener noreferrer" target="_blank">dappKit</a>, voc&ecirc; pode come&ccedil;ar a construir seus pr&oacute;prios smart contracts. &Eacute; um SDK web3 gratuito e de c&oacute;digo aberto que permite aos desenvolvedores criar aplicativos e produtos web3.O mais fascinante sobre o dappKit &eacute; que os desenvolvedores n&atilde;o precisam come&ccedil;ar a codificar do zero.

Eles s&atilde;o usados em cadeias de suprimentos, registro de objetos, libera&ccedil;&atilde;o de fundos, entre outros, como veremos mais adiante neste artigo.Essa flexibilidade &eacute; um dos benef&iacute;cios mais significativos dos smart contracts e &eacute; uma das raz&otilde;es pelas quais eles est&atilde;o sendo cada vez mais usados por diversos setores, que est&atilde;o prestando aten&ccedil;&atilde;o nos seguintes benef&iacute;cios dos contratos inteligentes:Confian&ccedil;a e Transpar&ecirc;ncia:&nbsp;Uma vez que todos os termos e transa&ccedil;&otilde;es s&atilde;o vis&iacute;veis e acess&iacute;veis, e nenhum terceiro est&aacute; envolvido, ningu&eacute;m pode alterar os acordos para benef&iacute;cio pessoal.Seguran&ccedil;a: Como a blockchain &eacute; a forma mais segura de criptografar dados, os smart contracts s&atilde;o virtualmente imposs&iacute;veis de serem hackeados. Lembre-se de que cada registro est&aacute; vinculado a uma cadeia de n&oacute;s, ent&atilde;o, para fraudar o contrato, uma pessoa mal-intencionada precisaria hackear toda a cadeia.Precis&atilde;o e Efici&ecirc;ncia: Quando uma condi&ccedil;&atilde;o pr&eacute;-determinada ocorre, o contrato &eacute; executado automaticamente, e todos os termos s&atilde;o salvos e registrados de forma expl&iacute;cita.Resultados Garantidos: Devido aos benef&iacute;cios mencionados acima, os smart contracts s&atilde;o r&aacute;pidos e n&atilde;o geram questionamentos. Contratos que se autoexecutam reduzem significativamente a necessidade de lit&iacute;gios.<blockquote>👉<a href="https://taikai.network/en/blog/cefi-vs-defi" rel="noopener noreferrer" target="_blank">&nbsp;CeFi vs DeFi</a>: o que voc&ecirc; precisa saber</blockquote><h3>Aplica&ccedil;&otilde;es dos smart contracts ✏️</h3>Os smart contracts podem ser usados para mais do que transa&ccedil;&otilde;es - eles t&ecirc;m diferentes aplica&ccedil;&otilde;es em v&aacute;rias ind&uacute;strias.Por exemplo, os bancos podem usar contratos inteligentes para empr&eacute;stimos e pagamentos autom&aacute;ticos. Al&eacute;m disso, os DAOs de seguros j&aacute; est&atilde;o aproveitando os contratos inteligentes para lidar com certos sinistros. A comunidade do DAO precisa aprovar o sinistro de seguro antes que seja concedido, de forma semelhante a como um conselho ou comiss&atilde;o aprova uma solicita&ccedil;&atilde;o.Al&eacute;m disso, os contratos inteligentes tamb&eacute;m podem ser usados em crowdfunding, por exemplo, quando as pessoas contribuem com dinheiro para um projeto e, se o gerente do projeto n&atilde;o atingir a meta, o dinheiro &eacute; automaticamente devolvido.Vamos examinar alguns exemplos de contratos inteligentes e estudos de caso para ver como eles funcionam na pr&aacute;tica.<h4>Gest&atilde;o da Cadeia de Suprimentos</h4>Existem quatro entidades em um fluxo de gest&atilde;o da cadeia de suprimentos: um fabricante, um fornecedor, um varejista e os clientes.Os smart contracts podem melhorar a efici&ecirc;ncia, velocidade e reduzir interrup&ccedil;&otilde;es nesse processo.Por exemplo, os agricultores podem inserir os detalhes dos alimentos em smart contracts, como origem, tipo de cultura e informa&ccedil;&otilde;es de armazenamento, usando blockchain, para que as informa&ccedil;&otilde;es armazenadas sejam acess&iacute;veis a todas as partes envolvidas.Em seguida, as empresas de processamento de alimentos podem fazer lances nas safras usando o smart contract, e uma vez que um lance &eacute; aceito, elas inserem informa&ccedil;&otilde;es de refino no blockchain.O pr&oacute;ximo passo &eacute; para as empresas de processamento transportarem os alimentos para os atacadistas, atualizarem os detalhes de transporte no blockchain e os atacadistas come&ccedil;arem a fazer lances atrav&eacute;s do smart contract.Por fim, o consumidor final rastreia os itens alimentares desde a cadeia de suprimentos no blockchain para garantir que todas as informa&ccedil;&otilde;es capturadas no smart contract sejam precisas.Em outras palavras, como as regras s&atilde;o incorporadas aos smart contracts, a conformidade dos alimentos &eacute; mantida em todas as etapas do processamento. Isso ajuda os consumidores a determinar a qualidade e a origem.<h4 id="isPasted">Com&eacute;rcio</h4>Os contratos inteligentes fornecem uma plataforma descentralizada segura que garante responsabilidade, transpar&ecirc;ncia e rastreabilidade ao conduzir opera&ccedil;&otilde;es comerciais.Por exemplo, a IBM Blockchain criou a <a href="https://we-trade.com/" rel="noopener noreferrer" target="_blank">we.trade</a> com o objetivo de criar um ecossistema confi&aacute;vel para o com&eacute;rcio com regras padronizadas e op&ccedil;&otilde;es de negocia&ccedil;&atilde;o simplificadas. O objetivo &eacute; reduzir o atrito e o risco nas negocia&ccedil;&otilde;es, al&eacute;m de agilizar a troca de informa&ccedil;&otilde;es e aumentar as oportunidades comerciais para todos os participantes, como empresas e bancos.<h4>Sinistros de seguros</h4>Em geral, as companhias de seguros sofrem com a comunica&ccedil;&atilde;o deficiente entre as partes, o que apresenta uma oportunidade de construir smart contracts nesta ind&uacute;stria, em vez de contratos em papel complicados. Al&eacute;m disso, os smart contracts reduzem significativamente a probabilidade de fraude e de apresenta&ccedil;&atilde;o de falsos sinistros para obter pagamentos.Sem a participa&ccedil;&atilde;o de terceiros, n&atilde;o h&aacute; espa&ccedil;o para manipula&ccedil;&atilde;o de ambos os lados, gra&ccedil;as aos algoritmos no c&oacute;digo inteligente de seguro que podem eliminar obst&aacute;culos administrativos, prever cen&aacute;rios de pagamento e executar as condi&ccedil;&otilde;es do contrato.Em um exemplo recente de smart contracts, a<a href="https://intellias.com/smart-contract-solution-vehicle-insurance/" rel="noopener noreferrer" target="_blank">&nbsp;Intellias</a> desenvolveu um aplicativo da web para permitir a compra de ap&oacute;lices de seguro de ve&iacute;culos online para seguradoras na Europa, como parte de uma solu&ccedil;&atilde;o de smart contracts.Como resultado, a seguradora obteve acesso a um conjunto de solu&ccedil;&otilde;es de smart contracts altamente escal&aacute;veis. O prot&oacute;tipo pode segurar ve&iacute;culos eletronicamente, gerenciar o hist&oacute;rico de seguro automotivo e enviar automaticamente sinistros de seguro automotivo.<h3>Riscos e desvantagens dos smart contracts ⚠</h3>Os smart contracts s&atilde;o um m&eacute;todo altamente seguro de fazer contratos entre todas as partes envolvidas. No entanto, os usu&aacute;rios devem estar cientes de alguns riscos e desvantagens dos smart contracts, como imutabilidade, confidencialidade, dados externos e quest&otilde;es legais.Vamos esclarecer:Imutabilidade &eacute; um dos principais desafios. As regras do protocolo n&atilde;o podem ser alteradas uma vez estabelecidas no blockchain.Embora isso aumente a seguran&ccedil;a contra fraudes, tamb&eacute;m torna os smart contracts mais dif&iacute;ceis de serem usados. Al&eacute;m disso, a imutabilidade do c&oacute;digo torna quase imposs&iacute;vel corrigir bugs.Quest&otilde;es de dados externos s&atilde;o outra desvantagem dos smart contracts, porque os blockchains raramente se comunicam fora da rede.Para resolver isso, os desenvolvedores devem usar or&aacute;culos, que s&atilde;o aplicativos que recuperam dados do mundo externo.Confidencialidade &eacute; um dos riscos dos smart contracts, porque o blockchain torna todas as informa&ccedil;&otilde;es de atividade dos n&oacute;s relacionadas &agrave;s transa&ccedil;&otilde;es dispon&iacute;veis.Portanto, se voc&ecirc; n&atilde;o quer que informa&ccedil;&otilde;es confidenciais sobre o seu contrato estejam dispon&iacute;veis, talvez seja melhor pensar duas vezes: aplicativos de blockchain podem ser adulterados por usu&aacute;rios maliciosos para revelar o estado do contrato.Quest&otilde;es legais tamb&eacute;m s&atilde;o uma preocupa&ccedil;&atilde;o, j&aacute; que n&atilde;o s&atilde;o necess&aacute;rios advogados ao usar smart contracts.Al&eacute;m disso, se posteriormente voc&ecirc; levar alguma discuss&atilde;o para o tribunal, &eacute; improv&aacute;vel que seja usado como evid&ecirc;ncia, pois a maioria dos pa&iacute;ses n&atilde;o considera os smart contracts legais de acordo com suas leis.<h3>Conclus&atilde;o 🔮</h3>Os smart contracts s&atilde;o &uacute;nicos, pois podem ser executados automaticamente em uma blockchain quando as condi&ccedil;&otilde;es predeterminadas s&atilde;o atendidas, sem a necessidade de terceiros. J&aacute; existem bons exemplos de smart contracts sendo usados em diversas ind&uacute;strias, como cadeia de suprimentos, com&eacute;rcio e modelos de seguro.A Su&eacute;cia j&aacute; utilizou smart contracts para estabelecer a propriedade de terras por meio de um registro imobili&aacute;rio baseado em blockchain, o que poderia abrir caminho para outros casos de uso de smart contracts governamentais e criar novas possibilidades para como im&oacute;veis s&atilde;o comprados, vendidos e gerenciados - desde a simplifica&ccedil;&atilde;o de documentos at&eacute; a cria&ccedil;&atilde;o de reposit&oacute;rios confi&aacute;veis de registros de terras.Outro exemplo &eacute; o vencedor do <a href="https://taikai.network/br/startuplisboa/hackathons/hackathome" rel="noopener noreferrer" target="_blank">HACKATHOME</a>, um hackathon imobili&aacute;rio realizado em Lisboa e hospedado pela <a href="https://taikai.network/en/hackathons" rel="noopener noreferrer" target="_blank">TAIKAI</a>, que desenvolveu um projeto que usa smart contracts para conectar propriet&aacute;rios de im&oacute;veis, investidores e curadores (como arquitetos).Apesar dos desafios enfrentados pelos smart contracts, n&atilde;o h&aacute; d&uacute;vida de que o futuro parece promissor. &Agrave; medida que mais empresas e ind&uacute;strias come&ccedil;am a adotar a tecnologia blockchain, a demanda por smart contracts tende a crescer.Portanto, desenvolvedores e programadores precisar&atilde;o continuar trabalhando para melhorar e aprimorar a tecnologia, a fim de garantir que ela permane&ccedil;a segura e confi&aacute;vel.Isso ser&aacute; essencial para a ado&ccedil;&atilde;o generalizada de smart contracts por empresas e consumidores.<h3>Explore os smart contracts por meio de hackathons!</h3>TAIKAI &eacute; uma plataforma de hackathon que conecta empresas a desenvolvedores talentosos para criar solu&ccedil;&otilde;es.
