Privacy computing application: aleo full parsing

        The Institute will further bring the full picture of aleo as "the first platform to provide full privacy protection applications" to readers, and analyze its internal and external advantages and possible heights in the future. Aleo was founded by howardwu, michaelbeller, collinchin and raymondchu in 2019. The team is composed of world-class cryptologists, engineers, designers and operators from companies such as Google, Amazon and Facebook (meta), as well as the University of California, Berkeley, Johns Hopkins University, New York University, etc.
        Team members initially proposed the zexe plan and published papers in 2018, intending to fill the market gap in the two dimensions of privacy and programmability in a new way. As previously introduced, the zexe architecture is to generate online transactions that can prove the correctness of the calculation without disclosing the details of the calculation by first calculating offline, so that the transaction can be verified by anyone in a very short time, and it can support many applications running at the same time, as well as large-scale applications. Aleo received $28million in financing led by andreessenhorowitz (a16z) in round a; Its round B financing received $200million from koramanagementlp and softbankvisionfund after the outstanding performance of testnet. It is the largest single financing amount in the zero knowledge certification track at present, and it is also the largest round of financing in the history of the zero knowledge industry.
        A big challenge for blockchain protocols is the trade-off between privacy and programmability. In the whole privacy network, the most important thing is to shield identities and transactions. As described in previous articles of the Institute, aleo meets the demand for programmable privacy through the zkcloud system. Zkcloud adopts a point-to-point, decentralized privacy computing mode, in which the blocked identities can interact directly (such as asset transfer) or programmatically (through smart contracts). In a typical public blockchain, program execution occurs on a chain in a global "virtual machine" (VM) run by each network node.
        Therefore, each node in the network must recalculate (and collectively agree) each step of a given program. This is not only inefficient, but also reduces speed and increases end-user costs. And because this VM must be able to access relevant information, privacy cannot be protected; Zkcloud overcomes these limitations by separating the application runtime from the state maintained by the blockchain. Combining zero knowledge recursive proof and aleo's consensus mechanism posw, aleo can achieve complete programmability and privacy, as well as higher transaction throughput than the VM model on the chain. On the other hand, the programs running in zkcloud are carried out offline. Compared with the on chain execution model such as Ethereum (where the program running time is limited by "gaslimit"), it is only necessary to submit the shielding transaction at the end of the calculation.
        This opens up more possibilities for more kinds of applications without consuming more transaction fees. According to the test network data, the fastest miner can calculate 100000 TPS per second, and the hash rate of the whole network reaches the peak of more than 200000 TPS per second; Through the above aspects, we can ensure that the network is sufficiently centralized and secure while maintaining high performance, which can provide a basic guarantee for large-scale applications. In terms of ecology, aleo is compatible with Ethereum, opening up the ecological interoperability with Ethereum, and a large number of DAPP applications can be seamlessly migrated to aleo, which saves a lot of RE development and compatibility time; At the same time, in order to let developers have a better experience, aleo built a program language Leo that is more friendly to zero knowledge proof application development, and its development environment leoplayground.
        Leo is a static type programming language inspired by rust, built specifically for writing private applications, and Leo aims to eliminate as many cryptographic knowledge requirements as possible. Aleo not only makes developers environmentally friendly, they also launched a developer incentive plan. Grant recipients are not only contributors to the ecosystem, but also people who continue to play a role in the aleo community beyond the scope of the original grant; Subsequently, it also introduced incentives for the test network to reward any developer who accepts and merges the snarkos and snarkvm repositories. Aleo's token economics aims to adjust the incentives of all stakeholders in the system in the simplest way possible to serve the aleo network.
        A key difference between aleo and other networks (such as Ethereum) is that the charges on aleo network can be calculated in advance. In aleo, there is no concept of "gas", but "aleo points", which are used to pay transaction costs. Aleo points quota is a key computing resource that can access Zero Knowledge Computing. Therefore, aleo points is a natural way for the market to price the value of zero knowledge proof of any program. The price of this asset should roughly represent the overall demand for Zero Knowledge Computing. Aleo points will be distributed among early supporters, builders and community members, as well as foundations or other entities that will provide grants and ensure the sustainable development of the network.
        In addition to the initial aleo points supply allocated among the aleo team, early supporters and community members, aleo will set aside a part for wider distribution after the main network is launched: in this form, aleo will focus on further decentralizing control and improving the quality of the open source community while complying with applicable laws and regulations. Aleo points will be designed as an inflation model, which is beneficial to early adopters of the network; In this way, aleo ensures the high security of the network as soon as possible. Aleo set a relatively high inflation release rate at the start, halving every three years in the first 10 years.
        After the ninth year, the final halving will lead to the release of 12.5 aleo points for each block at the same time, so as to ensure the security of the network and the stability of the economy it will support. Privacy is the foundation of the next generation Internet. According to the global ranking of invention patents of privacy computing technology, we can see that many capital institutions and Internet giants enter the market, on the one hand, because of the needs of market policies, and more importantly, because as the foundation of the next generation Internet, privacy computing technology has an extremely broad prospect. Aleo, as the first decentralized privacy application development platform, integrates zero knowledge encryption (zexe) technology to protect data on the network through the decentralized system of blockchain, providing users and application developers with absolute privacy computing and data protection.
        In order to make it easier for developers to get started, the project party integrated aleopm into aleostudio, which is the first IDE for private web applications. With aleostudio, developers can now quickly search and import new packages for use in their applications. The difference between aleo and other privacy solutions is that it is not trying to replace the existing network, but to integrate it with the existing network, both the performance of AWS and the security of blockchain. It adopts a new method of security, privacy and data ownership. Users no longer need to sacrifice information that they can never recover, and web services no longer need to risk damaging user data; On the premise of ensuring privacy and network performance, the original composability of the network is maintained, and the experience of users and developers is better.
        The next generation Internet is a relatively decentralized, automated and intelligent new Internet world based on the complete return of users' personal digital identity, digital assets and data to individuals. Every interaction between us should be recorded and quantified. We should own our own data ownership and use rights and participate in the resulting benefit distribution fairly. This requires joint exploration of a number of technologies, including blockchain, artificial intelligence and the Internet of things.
