## What Is LOCUS CHAIN (LOCUS)?
Locus Chain aims to be the most widely used Next Generation Layer 1 Public Blockchain Protocol, which achieves both full decentralization and scalability simultaneously. As a decentralized scalable layer 1 chain based on patented technologies, Locus Chain aims to support various Defi, GameFi, Metaverse, Smart City, CBDC(Central Bank Digital Currency) projects by being the most reliable, secure, low cost and high performance layer 1 public blockchain platform. 
Locus Chain claims to be the first decentralized Layer 1 public blockchain to ever solve the blockchain trilemma of Decentralization. Scalability and Security.

## LOCUS token?
The current Locus token type before the mainnet is an Ethereum-based ERC20 token with smart contract issued by Locus Chain Foundation. However, given that the tokens on the public Ethereum network cannot be used on the Locus Chain directly, we will be making use of hashed time-locked contracts to allow 1-to-1 atomic swaps of Locus tokens from Ethereum to the Locus Chain mainnet. LOCUS will be the main cryptocurrency required for all the operations of the Locus Chain network and all of its applications. LOCUS is a payment method for the entire network economy. Tokens are used by validators (who can easily participate), developers, and users to participate in the LOCUS network and receive rewards. It is also used to for fees and to participate in future governance.

## LOCUS Ecosystem
Top developers and high profile business partners are participating in the development of Locus Chain one after another. High-performance Layer 1 blockchain can create various business opportunities in sectors including decentralized finance, real estate transaction platforms, and game money, etc as well as creating various other tokens.
In addition, Locus Chain allows the users to use the blockchain verification service through a simple linkage without building a separate blockchain.
Since it is a high-performance public blockchain platform, technology licensing will be carried out in the future in the areas of CBDC and IOT, including smart cities, smart factories, and smart grids based on vast amounts of data.
 
## Special technology of LOCUS
*DAG(Directed Acyclic Graph) - AWTC(Account-Wise Transaction Chain)

The AWTC, Account-Wise-Transaction-Chain, is a central data structure for Locus Chain's high capacity, distributed transaction processing. AWTC is a Directed-Acyclic-Graph (DAG) based data structure composed of multiple transaction chains, each for an account. Each account has its dedicated chain. A new transaction issued by an account is primarily added to the account's chain.
Block grid structures, including DAG-AWTC, do not cause conflicts because there are as many points as the number of accounts to which the transaction is added, and only the owning account can record it exclusively.
Also, the account that added the transaction becomes clear, so if the account holder himself is not a malicious user, the transaction is almost confirmed as soon as it is added.
The ledger structure of the Locus Chain is one of the main technical features to fundamentally solve the problem of delayed transaction processing that the existing blockchains had.

* POS - BFT Consensus Algorithm
* 
Given the time required for the data to propagate sufficiently to the network, the Locus Chain first implemented a BFT definitive consensus on the DAG by attempting to consent on a small amount of historical points of time.
It also selects a new proposer committee that participates in the consensus algorithm every round by a random verifiable function (VRF) based on stochastic PoS (proof of stake: the more shares, the higher the probability of being elected as a committee). Since these methods cannot identify or predict the nodes (proposer, validator) to participate in the consensus, manipulation by malicious attacks is difficult, ensuring fairness and network stability of the consensus results.

*Verifiable Pruning

Unlike traditional pruning, which reduces the size of a ledger by simply deleting old data to address growing ledger sizes, Locus Chain's Verifiable Pruninng uses a Skewed Merkle Tree structure to validate the legitimacy of the data even when most of the previous data is deleted in the local environment. Verifiable pruning deletes outdated data on the ledger while still being able to provide full data verification by verifying previous data with hash values. 

*Dynamic Sharding

Locus Chain has a ledger structure formed of each account (AWTC), making it easy to adjust the number and size of the shard, and the validator ratio by relocating the shard in the event of an imbalance between shards. With dynamic sharding, the network usage that a node has to cover is reduced to 2/N when the number of shards is N. The total network TPS for network usage on the same node will increase by that amount, plus the additional ledger state sharding, which will also divide the storage usage by the number of shards.

## LOCUS’S creators
The key development members of the Locus Chain were developers of the Blueside Engine, Korea's first commercial game engine. The core of Locus Chain technology is to effectively process and synchronize large amounts of network traffic. The developers of Blueside Engine have acquired 18 software development related intellectual property rights, which are the product of the technology accumulated through console/online games and software development over the past 20 years, and hold 2 other software patents.

Bifrost is a multichain middleware platform that enables developers to create Decentralized Applications (DApps) on top of multiple protocols. Not restrained to a single blockchain, Bifrost creates a new environment where developers can combine the best protocols to develop substantially more scalable and flexible DApps.

With Bifrost, developers can write smart contracts for multiple blockchain protocols in an unified environment. They simply select the target blockchain for each part of the code, then Bifrost will transpile, compile, and deploy the code into the target blockchains at once. Developers can also easily operate their DApps and even switch the target blockchain as new and better protocols become available.

Bifrost has multiple components that allow for a seamless connection among all blockchains:

Recipe: A language application that defines the programming language of Bifrost and generates smart contract codes with guaranteed code-level flexibility.

Linker: A system that connects the user and Bifrost components, ensuring the seamless operation on top of multiple blockchains.

Builder: An Integrated Development Environment (IDE) that offers a customized environment to use the comprehensive suite of features of Bifrost.

Gourmet: An automated testing environment for Bifrost service and smart contract development, updating with the latest technologies for blockchain.

ABBC is a blockchain platform that enables secure payment transactions, helping to facilitate retail adoption of cryptocurrencies and make shopping online with digital assets a safer, more enjoyable experience for end-users.

The platform offers three main products: a multi-platform wallet capable of supporting Bitcoin (BTC) and Ethereum (ETH), in addition to a variety of other native cryptocurrencies and ERC-20 tokens; an online shopping application that can be used to shop at over 50 online retailers with cryptocurrencies; and a cryptocurrency exchange platform that offers secure trading and low transaction fees.

The ABBC Coin was created to give holders the ability to govern the development of the ABBC platform by delegating voting power to chosen block producers (BPs) — who are then able to vote on governance proposals. These governance proposals can be on a range of topics but might include launching strategic partnerships, implementing new features or expanding ABBC's services to new regions. Beyond this, ABBC Coins were created as a reward system for online shoppers and can be staked for regular rewards.

ABBC is currently based on the EOSIO blockchain, which enables it to achieve up to 5,000 transactions per second (TPS) while remaining environmentally friendly due to its energy-efficient delegated proof-of-stake (DPoS) consensus mechanism.

ABBC Coin was initially known as Alibabacoin but changed its name in March 2019 following a dispute with Chinese multinational e-commerce giant Alibaba.

MediBloc (MED) is a South Korean-based decentralized blockchain protocol for the healthcare industry through which medical institutions can securely transfer, collect, store and manage data. With MediBloc, physicians can access patient information, medical history, prescribed medication, insurance issues and more. MediBloc makes medical data more accessible by allowing everyone involved to track and record medical conditions, appointments, examinations, treatments and more.

The ecosystem is built on three key elements: MediBloc Core (a layer for storing data and providing additional storage), MediBloc Application (a layer for accessing and managing data through various applications), and MediBloc Service (a layer applying smart contract technology that connects the other layers and allowing input and output of data).

The platform offers three categories of accounts: for general users (patients), healthcare providers (doctors and medical institutions) and data scientists, the latter two require proof of their accreditation. The project is aimed at improving the quality of medical services and infrastructure by optimizing information storage processes and giving users sovereignty over their own data. MediBloc is compliant with the HIPAA Security Rule, the Health Insurance Portability and Accountability Act.

Strike is a DeFi lending protocol that allows users to earn interest on their cryptocurrencies by depositing them into one of several markets supported by the platform.

When a user deposits tokens to a Strike market, they receive sTokens in return. These sTokens represent the individual’s stake in the pool and can be used to redeem the underlying cryptocurrency initially deposited into the pool at any time. For example, by depositing ETH into a pool, you will receive sETH in return. Over time, the exchange rate of these sTokens to the underlying asset increases, which means you can redeem them for more of the underlying asset than you initially put in — this is how the interest is distributed.

On the flip side, borrowers can take a secured loan from any Strike pool by depositing collateral. The maximum loan-to-value (LTV) ratio varies based on the collateral asset, but currently ranges from 50 to 80%. The interest rate paid varies by borrowed asset and borrowers can face automatic liquidation if their collateral falls below a specific maintenance threshold.

Fei protocol is a DeFi native algorithmic stablecoin. The aim of Fei is to propose a technological solution in a sweet spot between rigid overcollateralized decentralized stablecoin and centralised custodial stablecoins.

Fei Protocol runs on two crypto assets: FEI stablecoin and TRIBE governance token.

FEI is aimed to be a more capital efficient and fully decentralized stablecoin. The protocol uses the value it controls to maintain liquid secondary markets and earn yield for the protocol.

The project was founded in December 2020 and immediately attracted significant interest in the crypto community. It resulted in $19 million VC investment in early March 2021. Among the names that have entered this project are Andreessen Horowitz (a16z), Coinbase Ventures, Nascent and Framework Ventures.

There were some issues with the peg in the original mechanism, but through a series of governance upgrades the protocol recovered in the months following launch.

Fei v2 intends to be a major upgrade for the system and will launch in late 2021. It features 1:1 redeemability for FEI against protocol reserves, TRIBE buybacks and backstop, and algorithmic protocol controlled value management.
