Mixin Network



Distributed Ledger Technology includes blockchain technologies and smart contracts. While distributed ledgers existed prior to Bitcoin, the Bitcoin blockchain marks the convergence of a host of technologies, including time-stamping of transactions, Peer-to-Peer (P2P) networks, cryptography, and shared computational power, along with a new consensus algorithm.

Cryptography has a key role to play both in the security, as well as in the immutability of the transactions recorded on blockchains. Cryptography is the study of the techniques used to allow secure communication between different parties and to ensure the authenticity and immutability of the data being communicated. For blockchain technologies, cryptography is used to prove that a transaction was created by the right person. It is also used to link transactions into a block in a tamper-proof way, as well as create the links between blocks, to form a blockchain. As the challenge of Blockchain scalability continues to handicap cryptocurrencies ascension to mainstream adoption, an industry wide arms race has been launched to produce a distributed ledger capable of achieving faster transaction speeds without compromising security or decentralization.

The Mixin Network  brings to market a multilayered platform built to enhance the speed, privacy and security of transactions between digital assets across multiple distributed ledgers.
Mixin provides a messenger app — ‘Mixin Messenger’, where users can store cryptocurrencies in their wallet, and perform lightening fast peer-to-peer transactions between contacts. Developers can also build new Dapps on top of the Mixin Networks infrastructure.
With bold claims of over a billion transactions per second, 0% transaction fees, and an infrastructure for cross chain Dapp development; Mixin is positioning itself to be the dominant solution to the blockchain scalability problem.
The Mixin Kernel distributed ledger uses a proof of stake consensus protocol. Kernel Nodes stake at least 10,000 XIN as collateral in exchange for the ability to validate transactions on the Kernel distributed ledger.
Each Mixin Kernel Node represents 10,000 XIN, which is approximate 2% of the network stake. The Kernel can only operate with at least 7 nodes joined, which is about 15% of the whole networks stake.

Privacy
For privacy, Mixin kernel uses a 1-time key generation algorithm, which allows the system to generate a ‘ghost address’ that can be discarded after each transaction a user makes.

Mixin Domain
The Mixin domain communicates with the kernel via system calls.
In order for an external asset (from the Bitcoin blockchain for example) to become associated with the Mixin kernel, a Mixin public key is first produced to connect with the domain, and then an asset specific public key (i.e a Bitcoin public key) is produced to connect the asset to the Mixin Kernel. If someone wants to send funds from their Bitcoin wallet to the Mixin network, the domain will create a transaction to the Mixin public key, and the Mixin kernel will verify the transaction.

Mixin Domain Extension
The Mixin domain extensions enable users to setup ‘smart contracts’ from a single computational unit (i.e your laptop or iPhone). These smart contracts are higher performing and more robust than those currently offered on the Ethereum blockchain.

XIN Token
XIN tokens are the main token used in the network. Like Bitcoin and Ethereum, the token is paid to those who support the network by validating transactions. XIN tokens are also staked in the proof of stake consensus protocol (at least 10,000 XIN tokens must be staked to join the network as a full node).
The Mixin Network also connects to different Dapps using API calls. These Dapps pay the network in XIN tokens based on the amount of resources the Dapp consumes.
The Mixin website describes the Mixin network as a complete Trusted Execution Environments (TEEs) and powered by the algorithm BFT-DAG that makes it possible to connect blockchains for optimal throughput. It is, therefore, an inter-blockchain communication system for helping users connect to other networks.
The unified blockchain platform is aimed at making communication instant and secure for all transfers from one chain to another. It also creates a platform that developers can use to make DApps keep drawing new meaning for the network and outdoing competitors.
The first DApp developed and activated in the network is the Secure Messaging app that utilizes the signal protocol to drive end-to-end messaging encryption. Here are the main components that help Mixin to work more efficiently;
·         Zero-knowledge proof.
·         Inter-blockchain communication protocol.
·         Secure end-to-end encrypted messaging channels.
·         Non-deterministic transactions that interact directly with trusted sources.
