 ## What Sui is
 
-Sui is a smart contract platform maintained by a permissionless set of authorities that play a role similar to validators or miners in other blockchain systems. 
+Sui is a smart contract platform maintained by a permissionless set of authorities that play a role similar to validators or miners in other blockchain systems.
 
-Sui offers scalability and unprecedented low-latency for common use cases. Sui makes the vast majority of transactions processable in parallel, which makes better use of processing resources, and offers the option to increase throughput with more resources. Sui forgoes consensus to instead use simpler and lower-latency primitives for common use cases, such as payment transactions and assets transfer. This is unprecedented in the blockchain world and enables a number of new latency-sensitive distributed applications, ranging from gaming to retail payment at physical points of sale.

Move programs define operations on these assets including custom rules for their creation, the transfer of these assets to new owners, and operations that mutate assets.

-Sui has a native token called SUI, with a fixed supply. The SUI token is used to pay for gas, and is also used as [delegated stake on authorities](https://learn.bybit.com/blockchain/delegated-proof-of-stake-dpos/) within an epoch. The voting power of authorities within this epoch is a function of this delegated stake. Authorities are periodically reconfigured according to the stake delegated to them. In any epoch the set of authorities is [Byzantine fault tolerant](https://pmg.csail.mit.edu/papers/osdi99.pdf). At the end of the epoch, fees collected through all transactions processed are distributed to authorities according to their contribution to the operation of the system. Authorities can in turn share some of the fees as rewards to users that delegated stake to them.

 ## Parallel agreement - a breakthrough in system design
 
 Sui scales horizontally with no upper bound to meet application demand while maintaining extremely low operating costs per transaction. Its system design breakthrough eliminates a critical bottleneck in existing blockchains: the need to achieve global consensus on a total-ordered list of transactions. This computation is wasteful given most transactions are not contending for the same resource against other transactions.

 Sui scales horizontally to meet the demands of applications. Network capacity grows in proportion to the increase in Sui authorities' processing power by adding workers, resulting in low gas fees even during high network traffic. This scalability characteristic is in sharp contrast to other blockchains with rigid bottlenecks.

 Move's design prevents issues such as [reentrancy vulnerabilities](https://en.wikipedia.org/wiki/Reentrancy_(computing)), [poison tokens](https://www.theblockcrypto.com/post/112339/creative-attacker-steals-76000-in-rune-by-giving-out-free-tokens), and [spoofed token approvals](https://www.theverge.com/2022/2/20/22943228/opensea-phishing-hack-smart-contract-bug-stolen-nft) that attackers have leveraged to steal millions on other platforms. Its emphasis on safety and expressivity makes it easier for developers to transition from web2 to web3 without understanding the intricacies of the underlying infrastructure.

 In Sui, this consensus protocol is required only when the transaction involves shared objects. When shared objects are involved, the Sui authorities play the role of more active validators in other blockchains to totally order the transaction with respect to other transactions accessing shared objects.
 
-Because Sui focuses on managing specific objects rather than a single aggregation of state, it also reports on them in a unique way: (i) every object in Sui has a unique version number, and (ii) every new version is created from a transaction that may involve several dependencies, themselves versioned objects. 
+Because Sui focuses on managing specific objects rather than a single aggregation of state, it also reports on them in a unique way: (i) every object in Sui has a unique version number, and (ii) every new version is created from a transaction that may involve several dependencies, themselves versioned objects.
 
 As a consequence, a Sui authority – or any other entity with a copy of the state – can exhibit a causal history of an object, showing its history since genesis. Sui explicitly makes the bet that in most cases, the ordering of that causal history with the causal history of another object is irrelevant; and in the few cases where this information is relevant, Sui makes this relationship explicit in the data.
 
 Sui guarantees transaction processing obeys *[eventual consistency](https://en.wikipedia.org/wiki/Eventual_consistency)* in the [classical sense](https://hal.inria.fr/inria-00609399/document). This breaks down in two parts:
 
-* Eventual delivery - if one honest authority processes a transactions, all other honest authorities will eventually do the same.
+* Eventual delivery - if one honest authority processes a transaction, all other honest authorities will eventually do the same.
 * Convergence - two authorities that have seen the same set of transactions share the same view of the system (reach the same state).
 
 But contrary to a blockchain, Sui does not stop the flow of transactions in order to witness the convergence.
 
 ## Common transactions
 
-[Many transactions](https://eprint.iacr.org/2019/611.pdf) do not have complex interdependencies with other, arbitrary parts of the blockchain state. Often financial users just want to send an asset to a recipient, and the only data required to gauge whether this simple transaction is admissible is a fresh view of the sender's account. This observation allows Sui to forgo [consensus](https://pmg.csail.mit.edu/papers/osdi99.pdf) and instead use simpler algorithms based on [Byzantine Consistent Broadcast](https://link.springer.com/book/10.1007/978-3-642-15260-3). These protocols are based on the [FastPay](https://arxiv.org/abs/2003.11506) design that comes with peer-reviewed security guarantees. In a nutshell, Sui takes the approach of taking a lock (or "stopping the world") only for the relevant piece of data rather than the whole chain. In this case, the only information needed is the sender account, which can then send only one transaction at a time.

 Sui further expands this approach to more involved transactions that may explicitly depend on multiple elements under their sender's control, using Move’s object model and leveraging Move's strong ownership model. By requiring that dependencies be explicit, Sui applies a _multi-lane_ approach to transaction validation, making sure those independent transaction flows can progress without impediment from the others.

 ## Sui Gateway services
 
-The Sui model encourages third parties to assist with transaction submissions. For example, if an app developer (e.g., a game developer) has many users, they can manage votes aggregation and certificate submission on behalf of their users. The app developer may use their own servers (e.g., where they store the state of the game) to run a _Sui Gateway service_. We provide a reference implementation of such a service.

 Instead of the app users attempting to send transactions to multiple authorities from their mobile device, which may degrade user experience, users may submit their transactions to the app, which forwards it to the Sui Gateway service run by the app developer. The Sui Gateway service conducts the entire transaction session and returns the results to the users. Security is assured since the app doesn’t need to know the users’ private keys; the app owner merely provides the bandwidth.
