V-swap Protocol

Core Decentralized Protocol of V-swap
The V-swap protocol is a peer-to-peer system designed for exchanging digital assets (BEP-20 tokens) on the BNB-Chain. The protocol is implemented as a set of persistent, non-upgradable smart contracts; designed to prioritize censorship resistance, security, self-custody, and to function without any trusted intermediaries who may selectively restrict access.
V-swap protocol, once deployed, will function in perpetuity, with 100% uptime, provided the continued existence of the BNB-Chain.

V-swap and typical markets

The important thing to assess here is how the Automated Market Maker design deviates from traditional central limit order book-based exchanges, and how permissionless systems depart from conventional permissioned systems.

Order Book VS AMM

Order Book VS AMM

Most publicly accessible markets use a central limit order book style of exchange, where buyers and sellers create orders organized by price level that are progressively filled as demand shifts. Anyone who has traded stocks through brokerage firms will be familiar with an order book system.
The V-swap protocol takes a different approach, using an Automated Market Maker (AMM), sometimes referred to as a Constant Function Market Maker, in place of an order book.
At a very high level, an AMM replaces the buy and sell orders in an order book market with a 'liquidity pool' of two assets, both valued relative to each other. As one asset is traded for the other, the relative prices of the two assets shift, and a new market rate for both is determined. In this dynamic, a buyer or seller trades directly with the pool, rather than with specific orders left by other parties. The advantages and disadvantages of Automated Market Makers versus their traditional order book counterparts are under active research by a growing number of parties.

Permissionless Systems

The second departure from traditional markets is the permissionless and immutable design of the V-swap protocol. These design decisions were inspired by the commitment to the ideals of permissionless access and immutability as indispensable components of a future in which anyone in the world can access financial services without fear of discrimination or counter-party risk.
Permissionless design means that the protocol's services are entirely open for public use, with no ability to selectively restrict who can or cannot use them. Anyone can swap, provide liquidity, or create new markets at will. This is a departure from traditional financial services, which typically restrict access based on geography, wealth status, and age.
The protocol is also immutable, in other words not upgradeable. No party is able to pause the contracts, reverse trade execution, or otherwise change the behavior of the protocol in any way.
