Cosmos Ecology-DVPN White Paper (2) Overview of Sentinel Based on Cosmos Block Architecture

cosmos: the future of the decentralized cryptocurrency ecosystem

Interoperability solutions facilitate the exchange of assets and data between decentralized networks of various cryptocurrencies, reducing tribalism in the industry. under such circumstances,

“Tribalism” refers to the aggressive tendencies that decentralized networks exhibit when trying to establish or demonstrate their superiority over their opponents.

The truth is that some networks have unique service propositions, which are supported by their custom architecture and unique development focus. Interoperability enables participants in the ecosystem to leverage the benefits of these networks simultaneously without comparison, enabling horizontal scalability/specialization.

Cosmos aims to reduce this "tribalism" in the ecosystem by linking these competing chains together, effectively reducing the impact of significant fragmentation that would normally separate them. The Cosmos IBC module will allow these on-chain applications to expand their overall target market demographic by catering to a wider user base, helping to easily acquire new customers by enabling them to accept dynamic cross-chain payments.

Currently, the most important interoperability initiatives between Cosmos and other high-value and respected networks include the interoperability “bridges” being built from Cosmos to ZCash and Polkadot.

The Cosmos ecosystem enables Sentinel to build and manage its own native chain at the "hub" layer. Whereas dVPN applications built on Sentinel networks are either in a shared area or in their own local area, depending on the throughput needs of each application.

Chains built using Cosmos have the ability to maintain governance-related autonomy while also ensuring interoperability among other hubs and regions in the Cosmos network.

Unlike the ERC20 token model, chains built on Cosmos will not have to pay fees "ATOM" in Cosmos' native token, instead they will have the ability to pay in the chain's native token.

Hub and Zone Structure

Sentinel uses the Cosmos Hub/Zone architecture by exchanging all application-specific transactions and data on the "Sentinel dVPN Zone" (or sidechain), while abstracting token-related transactions and governance to the "Sentinel Hub" (or main On chain 0, to improve the scalability associated with dVPN dApps. Zone will communicate with Sentinel's main chain (hub) through Cosmos' Inter-Blockchain Communication (IBC). Zone can be loosely likened to a "state channel", It is deployed for efficient scaling.

The "dVPN" application-specific zone will have its own consensus governance, which is likely to be a subset of the Hub's consensus validator participants. While there is no monetary value exchange at the Zone level, the incentivization and de-incentivization of validators will take place at the Sentinel Hub level.

Using IBC, the hubs of the Sentinel network communicate with the Cosmos Hub and other hubs that are part of the Cosmos Network. Not only will this enable services in the Sentinel network to communicate with each other and accept the native token SENT or other whitelisted tokens, but it will also help them connect with other networks in the Cosmos network.

Sentinel - The Tendermint blockchain can host its own independently run dApps and/or service areas allowing its own set of validators to validate transactions through specific governance built on top of the Tendermint consensus.

Throughput

Tendermint uses the bPOS consensus system, where the blockchain can have a limited number of validators set up to achieve faster consensus while protecting the network from "Byzantine attacks."

Various P2P communication and privacy solutions will be built on the Sentinel network and will rely on high-volume, microtransaction-based revenue models. This makes the Tendermint blockchain perfect to support the Sentinel network, as it is able to achieve high TPS (transactions per second), especially with Ethereum's much lower "15 transactions per second".

Blockchains using Proof-of-Work (POW) consensus transactions per second (TPS) are slow relative to the blockchain frameworks used to build decentralized VPN applications, and many scaling solutions for such consensus networks require dedicated Hardware makes a high capital investment.

Cosmos uses a unique bond-Proof-of-Stake consensus in which votes from a fixed number of validators, with a certain amount of entropy, are accepted by the network at a specified point in time. This increases the overall throughput of transactions on the network as there is a limited number of validators processing transactions.

Tendermint’s BFT consensus system allows the Sentinel network to achieve faster transaction speeds than any current existing PoW network; PoW networks are hindered by the lack of clear finality. In bpos-based systems (like Tendermint), by using a poll-based voting system, utilizing a limited number of validators, by allowing token holders to "bind" tokens to validators deemed trustworthy , achieving a near-instant end.

interoperability

The interoperability of Cosmos' IBC protocol allows the creation of a peg (backed by a stablecoin). This feature can be developed for chains that are not part of the Tendermint or Cosmos ecosystem.

The utility of these zones will be mainly used for cross-chain payments. With this technology, community-hosted nodes running on the Sentinel dVPN network can accept cryptocurrencies like Ethereum, BTC, PIVX, DASH, NEO, Dfinity, Cardano, and more in exchange for bandwidth.

Any cryptocurrency can be integrated, whether it is built on the Cosmos SDK or not. This is achieved by using "bridging", which requires an interoperable connection between the two networks. This “Sentinel Hub” will connect to Cosmos IBC, and dVPN users can pay in different currencies or stablecoins supported by Cosmos IBC.

Since the IBC protocol can be effectively used for communication between different networks with different consensus mechanisms and structural diagrams (such as ZCash/Cosmos), Sentinel believes that, by introducing the Hub/Zone model, the IBC protocol can be used in transaction scalability and dAPP related. Very effective in terms of efficiency.

The technology provided by the Cosmos network and Tendermint allows us to envision a true free market economy, driven by "perfect cross-chain payment integration" that has not been possible with any other platform/network so far. This is the first step in a long journey to create real-world blockchain applications.

Governance

On Sentinel’s cosmos-based mainnet, network governance will be in the hands of validators. These validators will be determined democratically on the cosmos-based Sentinel mainnet through delegation of holders. A validator’s “voting power” or weight is determined not only by historical performance, but also by the number of tokens that Sentinel supporters have delegated to them.

Network governance proposals are handled by a group of democratic validators, bypassing the requirement to fork to a "new chain". These suggestions can include:

• Accept new validators or reject existing malicious validators
• Accept new zones and bridges, or reject existing ones
• Change the supply or lock a malicious/hacked account
