Editor's Notes
- Web application Millions of users->scalabile su tutte le industry, critical mass needed Free for app users->senza costi di transazione Responsive->no latency, lag few sec Upgradable->permettere agli sviluppatori di aggiornare gli smart contract Account names->real names No purchase necessary Account recovery->lost keys Thousand of actions per sec->sequential and parallel performance Bug recovery->bug exists
- Ogni app ha bisogno services (account, recovery, permission) Ogni app cerca di implementare OS in modo diverso (come Vista on x86) --- If you look at the blockchain industry, everyone wants to build smart businesses, decentralized organizations, etc..., and in the process developers built decentralized computers from the ground up which can run their smart apps. In this process, all app developers have to solve many of the same problems: account systems recovery processes multi-sig manage challenges What they're missing is the operating system, which could provide all the common features that every application depends upon, allowing applications to focus on what makes them different. For example, there is a huge commonality between Bitshares and Steem in terms of functions, and relatively a very small difference in terms of application business logic.
- EOS aims to provide this operating system to provide all the core functions to app developers and allow them to focus on just the business logic that makes their apps unique. *** If you look at the blockchain industry, everyone wants to build smart businesses, decentralized organizations, etc..., and in the process developers built decentralized computers from the ground up which can run their smart apps.

- Account permission-auth & permission mngmt Indexed db multi user control Interapp (sync e async) *** EOS provides parallel processing of smart contracts through horizontal scalability, asynchronous communication, and interoperability. It will provide databases, account permissions, scheduling, authentication, and internet-application communication. For example, both Bitshares and Steem can be run on EOS in parallel, and because of the asynchronous communication, additional nodes and entire clusters can be thrown behind the processing of transactions to scale up to any transaction volume you want. EOS is the first blockchain operating system. It provides your application with databases, a schema, multiple indices so you can have sorted data that's easy to manage. it gives you account permissions and a whole set of users, account recovery, handles all the complexities of scheduling multiple tasks across CPU cores or even clusters, handles all the authentication and key management so you can focus on business logic and not cryptography, and it handles all the internet-application communication. EOS is the operating system that we've been waiting for that allows us to focus on building the apps that our users need without getting in the way, without forcing gas, without requiring users to purchase anything before using, and it dramatically accelerates the rate at which developers can build apps.
- Scalable Goal 1000s DAPPs removing cpu bottlenexk Parallel Read only in parallel, write spep in sequence Flexible Freeze->se DAO happen no hard fork, collectively update single application Eliminate gas https bug dopo molti anni Multiple vm->messages Web assembly industry standard Add other languages Governance Election P2p agreement->costitution e autorithy Dispute happen/bug happen->process con jurisdiction Self funded Usable for developper Trasparenza->database by schema Tutto è leggibile Permission system declarative ---- Scalable: EOS can support 1000s of commercial-scale DAPPs through parallel execution and asynchronous communication. It separates the authentication from the action. For example, a transfer is a simple action of reducing one account's balance and increasing another, but all the authentication steps are validating signatures, checking to make sure that are sufficient funds, etc... but authentication steps only need to happen once when the block is produced. After a block is irreversibly added to the blockchain you never have to authenticate again. EOS puts the source code on the blockchain so that it is human readable what the contract says, and everyone can see it and developers can optimize it and compile on different machines, all without breaking consensus. It also eliminates gas to eliminate the extra operations that are required to count the important operations. Flexible: Because EOS will use delegated proof-of-stake, if an app is broken or fails, elected block producers can freeze the application until a bug can be fixed and then update the code. So if the DAO had been implemented on EOS, for example, it could have been frozen, fixed, and updated, all without ever having to hard fork or disrupt any other application on the chain. EOS is also flexible in the sense that you only have to run the applications that you need. If you are running an exchange, you don't have to run the social media apps, and you can configure your local node to process only the data you care about. Not every node needs to run and maintain the full state of the blockchain. EOS also publishes source code, not assembly, and provides generalized role-based permissions. Usable: EOS will include a web toolkit for interface development, self-describing interfaces (data that goes on the blockchain can be read by humans but is also compressed), self-describing database schemas, and a declarative permission scheme. This allows a fine-grained level of permissions in which you can easily delegate specific account permission to other accounts. Governance: Delegated proof-of-stake has elected block producers. A legally binding constitution (think decentralized peer-to-peer terms of service) establishes a common jurisdiction for disputes and dispute resolution. EOS will also include self-funded community benefit apps that are selected through stake-weighted voting. Ever account will have to sign the constitution. One idea is that every transaction may include the hash of the current state of the constitution. The constitution itself is something that can be modified and evolve, and captures the intent of what the blockchain is trying to express and guides the way when trying to resolve disputes. Signing the constitution expires if you do not use the platform just like other apps updating their terms of service.
