Such a platform employs the\u00a0<strong>TEEs (secure execution environments)<\/strong>\u00a0available on numerous\u00a0<strong>CPUs<\/strong>\u00a0with the goal of achieving the development of a blockchain that features advanced capabilities in terms of\u00a0<strong><a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-a-smart-contract\/\">smart contracts<\/a>\u00a0and privacy.\u00a0<\/strong><\/p>\n<p>Among the features that make this project ideal to meet the above objectives are\u00a0<strong>confidentiality,<\/strong>\u00a0since it prevents the leakage of input, output or intermediate state of a confidential smart contract and only responds to authorized queries to the contract. Another feature is the<strong>\u00a0integrity<\/strong>\u00a0of its code. This is because any user has the power to verify that an output has been performed by a given\u00a0<strong>smart contract<\/strong>\u00a0published on the blockchain.<\/p>\n<p>Another feature to note is\u00a0<strong>availability.<\/strong>\u00a0This is because there is no single point of failure if a miner is disconnected. The last feature I would like to highlight is<strong>\u00a0interoperability<\/strong>. This feature in the blockchain world is extremely important and this project features it, as contracts can operate with each other with other external blockchains.

Thanks to this\u00a0<strong>technology, Phala Network<\/strong>\u00a0can become a blockchain platform with confidential smart contracts, powered by a block production system that uses the power offered by CPUs in addition to a set of specialized functions called \u201c<strong>Secure Enclaves<\/strong>\u201c. Through these functions, Phala Network seeks to offer users certain confidential computing and data protection services.<\/p>\n<p>At present, this project is built on the Polkadot network and is mainly oriented to take over one of the\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-a-parachain-and-how-does-it-work\/\">parachains<\/a>\u00a0that are available on this network. It should be noted that Phala has a Canary Islands network known as Khala.<strong>\u00a0This network is based on the\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-kusama-ksm\/\">Kusama<\/a>\u00a0network.<\/strong><\/p>\n<p>To achieve the main goals of the project, the developers created Phala Network to support the operation of their network in the\u00a0<strong>Trusted Execution Environment<\/strong>\u00a0(TEE). TEEs are a special feature of CPUs. It is worth remembering that CPUs are processors that can be found in both computers and cell phones.<\/p>\n<p>The function of the TEEs allows this project to develop an\u00a0<strong>execution environment<\/strong>\u00a0that is highly secure for smart contracts. Through this operation, leaks of users\u2019 private information are prevented.<\/p>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div id=\"image_1073364914\" class=\"img has-hover x md-x lg-x y md-y lg-y\">\n<div class=\"img-inner dark\"><img fetchpriority=\"high\" decoding=\"async\" class=\"attachment-large size-large lazyloaded\" src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2022\/01\/Phala-Network-PHA1.jpg\" sizes=\"(max-width: 768px) 100vw, 768px\" srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2022\/01\/Phala-Network-PHA1.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2022\/01\/Phala-Network-PHA1-300x205.jpg 300w\" alt=\"Phala-Network-(PHA)\" width=\"768\" height=\"526\" data-srcset=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2022\/01\/Phala-Network-PHA1.jpg 768w, https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2022\/01\/Phala-Network-PHA1-300x205.jpg 300w\" data-src=\"https:\/\/www.bitnovo.com\/blog\/wp-content\/uploads\/2022\/01\/Phala-Network-PHA1.jpg\" data-sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/div>\n<\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<div class=\"is-divider divider clearfix\"><\/div>\n<h2><span class=\"ez-toc-section\" id=\"phala_network_system_parts\"><\/span><strong>Phala Network system parts<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The Phala Network is supported by the following components for proper operation:<\/p>\n<ul>\n<li aria-level=\"1\"><b>Users.\u00a0<\/b>Users are the most important part of the system. They connect, query and upload smart contracts on the network. In addition, users interact with these smart contracts via the blockchain with the help of working nodes.<\/li>\n<\/ul>\n<p>Users are able to\u00a0<strong>verify data<\/strong>\u00a0on the blockchain and also assist in cryptographic testing by running the project client or an entire node. It should be noted that no special hardware is required for users to employ confidential contracts. This capability is available on all current processors from 2015 onwards.<\/p>\n<ul>\n<li aria-level=\"1\"><b>Remote authentication service.<\/b>\u00a0This is a public service to confirm whether a running node successfully implemented the\u00a0<strong>pRuntime<\/strong>\u00a0(runtime). In this case, an encryption generated by the service as cryptographic evidence can prove that a specific output produced by the former service was created using the pRuntime executed on a\u00a0<b>TEE.\u00a0<\/b><\/li>\n<\/ul>\n<ul>\n<li aria-level=\"1\"><b><a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-a-first-generation-blockchain\/\">Blockchain<\/a>.\u00a0<\/b>The blockchain represents the backbone of the Phala Network project. The blockchain stores the identities of working Nodes, executed smart contracts, the status of encrypted contracts in addition to transactions issued by users and other blockchains. By connecting to a Polkadot parachain slot, the blockchain is able to\u00a0<strong>interoperate<\/strong>\u00a0with other blockchains via\u00a0<b>the\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-polkadot-dot\/\">Polkadot<\/a>\u00a0relay chain.<\/b><\/li>\n<\/ul>\n<ul>\n<li aria-level=\"1\"><b>Work nodes.\u00a0<\/b>Working nodes are responsible for executing confidential contracts using TEE-compatible hardware. These nodes operate off-chain, that is, they are external to the blockchain. Each node contains a specific program called\u00a0<strong>pRuntime<\/strong>\u00a0which is deployed in the secure part of the\u00a0<strong>TEE<\/strong>\u00a0mentioned above. These working nodes have three functions that guarantee the correct functioning of the network:<\/li>\n<\/ul>\n<ul>\n<li aria-level=\"1\"><b>Genesis Node.\u00a0<\/b>The Genesis\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-a-node-its-importance-in-cryptocurrencies\/\">Node<\/a>\u00a0is responsible for helping to start up the network and establishes the cryptographic configuration. There is only one Genesis Node in the entire network and it is destroyed after the launch of the Phala Network.<\/li>\n<\/ul>\n<ul>\n<li aria-level=\"1\"><b>Gatekeepers<\/b>. Gatekeepers are responsible for managing the\u00a0<strong>secrets<\/strong>\u00a0that ensure\u00a0<strong>the availability and security<\/strong>\u00a0of the network. Gatekeepers are dynamically elected on the blockchain and must perform staking within the network in order to be elected. For the task they perform of being online they are rewarded. If they make mistakes they will be removed for misbehavior, as there must be a certain number of functional Gatekeepers at all times.<\/li>\n<\/ul>\n<ul>\n<li aria-level=\"1\"><b>Miners.<\/b>\u00a0Finally, we have the miners. They are in charge of executing confidential contracts. They provide the computer resources to the users and for this they receive a reward. Although the operation is very similar to the Gatekeepers there is a\u00a0<strong>difference<\/strong>\u00a0and that is that the miners only need to bet a small amount of the Phala token and they also have the power to enter and leave the network as and when they want.<\/li>\n<\/ul>\n<p>It should be noted that to be part of PHA mining it is necessary to\u00a0<a href=\"https:\/\/www.bitnovo.com\/blog\/en\/what-is-cryptocurrency-staking\/\">stake<\/a>\u00a0about\u00a0<strong>1,620 PHA tokens<\/strong>\u00a0for each CPU core used in mining.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Tiempo de lectura:<\/span> <span class=\"rt-time\"> 3<\/span> <span class=\"rt-label rt-postfix\">minutos<\/span><\/span>Have you ever heard about\u00a0what Phala Network is?\u00a0This is a project aimed at providing a distributed computing platform that features high security and privacy.
