Singapore, 14 April 2022 — MAP Protocol(MAP), the leading cross-chain interoperability solution, has announced the addition of an oracle provider, NEST Protocol, to the MAP ecosystem. This integration will make end-to-end customizable oracles available to MAP-powered dApps. In line with the NEST deployment on MAP, MAP Protocol can accelerate the process of bringing the many great benefits of NEST to the MAP ecosystem. Dapps on the Makalu network, the testnet of MAP Protocol, are also able to use NEST oracle.

Since 2018, MAP Protocol development team has been committed to the principle of decentralized asset contract custody and calls, as well as continued to push development and operation. With hard work and effort, MAP Protocol’s ecosystem is growing rapidly and widely acknowledged as the best player in the cross-chain interoperability field.

NEST Protocol is a distributed price oracle based on the Ethereum network. It utilizes a unique “quote mining” mechanism to provide unparalleled fairness and accuracy for asset pricing and market-making. NEST offers the ‘channel’ tool, through which everyone can open a new quote channel and configure the economic model for that. What’s more, any channel can make bulk quotes for any tokens.

In lockstep with the rise of DeFi, oracles have quietly become the foundational element for emerging DeFi applications, as dApps depend on reliable, verified external data feeds. With the majority of MAP ecological projects operating solely on the MAP blockchain, NEST will specifically source data feeds of MAP Network native assets by scraping information directly from MAP native markets, such as HiveSwap. This will enable MAP-native projects to receive data from a MAP-native oracle, ensuring a frictionless, transparent, and customizable data infrastructure with maximum coverage of asset price data.

NEST integration with MAP will allow developers within the MAP network to build unique price feed oracles, customizing the specific methodologies used and the data sources to deliver maximum adaptability and transparency.

MAP’s Eco Director, Vincent, said of the integration, “Thanks to this partnership, MAP Protocol can accelerate the process of bringing the many great benefits of NEST to the MAP ecosystem. We are very excited to contribute to its adoption by helping new dApps have access to transparent and reliable data. Developers on MAP can now start using NEST oracles to build new use cases for any digital asset.”

About NEST Protocol

NEST oracle adopts the market game theory to synchronize the off-chain market price information onto the chain through miners’ quotations. NEST mining mechanism aims to incentivize quotation miners, making it a logically closed-loop distributed quotation system with the breaking features of collateral quotation, arbitrage verification, price chain, beta coefficients, and other modules. Currently, NEST Protocol is deployed on multi-chain, including Ethereum/Polygon/MAP/KCC/BNB.

MAP Protocol Semi-Monthly Report #88 (March 16th — March 31st) was originally published in MAP Protocol on Medium, where people are continuing the conversation by highlighting and responding to this story.

n terms of voting, there are two types of approaches in the market:
1. Voting with lock-up and
2. Voting provided with address snapshot without lock-up.

Considering the market value, voting with lock-up is beneficial to community users in the long term; however, it makes users bear the risks of price fluctuations on MAP tokens. how to solve this problem?

The core development team of MAP proposed to cooperate with Idavoll and create lock-up voting with their advanced technological modules. The mechanism provided by Idavoll will not affect the liquidity of community users and it can add modules for MAP token derivatives.

The details are as follows:
1. Users deposit MAP tokens into the Idavoll staking module, which lasts for 90 days each term. Users can stake again for the next term.

2. Users will get 12% APY of the lock-up tokens.

3. Meanwhile, users will get an XMAP as a voucher.

4. Each XMAP will automatically generate one GMAP (governance MAP) and one YMAP (yield MAP). GMAP is a voting token, while YMAP is a yield token.

5. Users can participate in any governance events by owing GMAP tokens.

6. Users who do not want to go through the above procedure but want to participate in governance can buy GMAP directly from Hiveswap.

7. HiveSwap will list XMAP/MAP pair to ensure the users’ MAP lock-up that they can freely transact the MAP tokens (theoretically, XMAP contains 12% of APY, and the price will be 12% higher than the MAP price).

8. HiveSwap will list XMAP/GMAP pair. The initial price is set as 1GMAP = 0.2 XMAP. It will fluctuate with the market.

9. HiveSwap will list XMAP/YMAP pair. The initial price is set as 1YMAP = 0.8 XMAP. It will fluctuate with the market.

10. If users want to withdraw their MAP tokens from the staking pool, they can combine GMAPs and YMAPs in a 1:1 ratio and get the corresponding XMAPs. Then, users can use XMAPs to swap MAP tokens.

11. Users need to swap MAP tokens into ETHs or USDCs on HiveSwap.

12.The MAP Protocol team has 33% of the voting rights for each proposal.

Reward proposal:
1. Voting governance, MAP staking, 90 days, APY 12%.
2. Add XMAP/MAP pair with APR 5%.
3. Add YMAP/XMAP pair and GMAP/XMAP pair with APR 5%.

MAP Protocol Mainnet Related Announcements was originally published in MAP Protocol on Medium, where people are continuing the conversation by highlighting and responding to this story.

Let’s first understand what APR is and how it is calculated. APR refers to ‘Annualized Percentage Rate’. APR is different from APY that takes the annual rate of return WITHOUT compound interest. Ex. 200% APR: $1 => $2. Does the higher APR, the better choice? That’s not true — the motivation for staking stems from the belief in the future growth potential of the token you are staking. For successful staking, the following factors are crucial.

1. Stability of token price: The price of the token you are staking is most important.

2. Value of token: Token staking rewards are only valuable if the token you staked is valuable.

The most important thing for staking is, above all, the price change of the token you staking. Here are key reasons why MAP protocol is the best choice.

Recently, many projects started native token staking upon launch. However, Map Protocol opens LP staking pool two years after its first launch. MAP Protocol has launched a testnet after long and in-depth research and development over the past two years and is set to launch the mainnet this quarter.

There are two types of blockchain projects. One is the project that starts staking at the same time of its launch and lists its tokens on the exchange in a few days. The other is that it starts staking after the test of time. What is the difference? Projects that begin staking programs on the first launch day mainly offer astronomical staking APR interest rates. And in just a few days, apr drops to 1/10 and even 1/100. And the price of tokens, which used to run on high ground at the time of their initial launch, soon fell sharply. No matter how high apr interest rates are, it can become useless when a token price approaches zero exchangeable value.

Token prices are volatile and can drop quickly. If your staked assets suffer a significant price drop, that could outweigh any interest you earn on them. Staking requires locking up investors’ tokens for a minimum amount of time. During that period, investors cannot do anything with staked assets, such as selling them. The most considerable risk we face with crypto staking is that the price decreases.

Based on this, I will introduce why MAP protocol is the best option for staking.

1. Map Protocol is a very stable project that has gone through its technical development for the past two years and has always tried to be innovative. And also, it is a project that has already experienced many types of market fluctuation through two years of operations, and we have learned how to overcome any facing risks.

2. The potential for future price hikes of MAP tokens is very noticeable. MAP protocol is the first true decentralized cross-chain bridge without any centralized nodes. It operates a testnet and is going to launch the mainnet this quarter.

3. MAP protocol adopts DAO governance. So, insider ownership in MAP protocol is significantly lower than in other projects. The graph is shown below:

Lastly, our team doesn’t want to be a smooth talker. Even if it may not receive explosive attention from the market, we want to be a trustworthy project that runs long-term and gains people’s trust.

Staking Rewards Calculations

Understanding how the MAP Protocol calculates and distributes token rewards is essential. The amount of staking rewards one can earn is proportionate to the total amount of tokens staked to the LP pool(MAP-ETH/ MAP-USDC).

For example, if there are 1000 total tokens staked and you have staked 100 of them, you can earn 10% of the total rewards distributed to the pool. If there are 2000 tokens staked in the pool and you have staked 100 of them, you’ll only earn 5% of the total rewards.

As is familiar with the PoS mechanism, the total number of staked tokens will increase as the pool matures and more people become familiar with it. It means that while today Staking rewards are split between a pool of a number of tokens, in the coming days, months, or years, that total amount of tokens staked could be as much as big. In theory, if you assume that there are 100 million tokens that were staked now and will be 400 million tokens staked in the future, you would receive ¼ of the number of rewards as one would today with only 100 million tokens staked. Keep this framework in mind as you consider staking to the network to earn token rewards on MAP protocol!

MAP Protocol Semi-Monthly Report #86 (Feb 16th — Feb 28th) was originally published in MAP Protocol on Medium, where people are continuing the conversation by highlighting and responding to this story.

We are excited to announce that MAP Protocol has officially launched its testnet Makalu Poc-1 after a period of endeavor of the core development team and all contributors.

MAP Protocol aims to be the secure end-to-end solution for any blockchain resident to move and exchange assets. To fulfill this role, MAP team is building on three layers simultaneously: a dedicated blockchain served as the infrastructure freeway connecting all kinds of blockchains to break the barriers, the MAP Assets layer where all kinds of assets are mapped to MAP chain in a non-custodial style via trustless smart contract, and the DeFi Application layer where all kinds of applications including but not limited to DEXes, games and NFTs can be built with the cross-chain capabilities enabled by the MAP chain and MAP assets.

The key features of the testnet Makalu Poc-1 are as follows:

1. Light client verification

Makalu Poc-1 deploys the POW consensus algorithm and fundamental block structure and verifies on-chain transactions of the target chain via light clients to realize the exchange of transaction data and assets between chains. MAP Protocol uses a dedicated blockchain to maintain all light clients, which are the basis of cryptographic verification. The correctness of the light client state is critical to the security of MAP Protocol.

2. Transferring assets from Ropsten to Atlas

Makalu Poc-1 currently provides supports for transferring assets (USDT) from Ethereum testnet Ropsten to Atlas in an entirely decentralized manner. The MAP blockchain is completely compatible with EVM and it protects users’ assets with transparent smart contracts using. In the future, users can enjoy one-stop asset transfer services without limitation between all blockchains through smart contracts and light clients maintained by the MAP chain.

The architecture of Makalu Poc-1 is mainly composed of three parts:

i) On-chain contracts: it used to define the cross-chain message entry between major chain networks, burn and mint processes of assets.

ii) Relayer: it can realize Atlas’s functions of data professing among different chains, storage framework of light client data, synchronization of light client data between chains, and relay of transactions. Each external major chain network that integrating into the MAP cross-chain ecosystem can support multiple relayers.

iii) Main network: by building a dedicated MAP public chain, the main network is committed to achieve interoperability among various types of blockchains, effectively providing services for on-chain data, assets transaction and verification.

The launch of Makalu Poc-1 will further improve and test the development of MAP. MAP Protocol will update on our latest developments soon.

What Is Relay?

Relays enables blockchain interoperability by allowing chains to verify events and block headers on another chains. Essentially, this simply means a contract on one chain (Chain A) is able to notice and verify event changes on Chain B. The notice part is handled by nodes known as ‘Relayers’, where they are the actual workhorses responsible for relaying cross-chain messages to keep MAP chain and all relevant contracts updated. The verify part is feasible thanks to cryptographic proof as well as the concept of light client.

One of the distinctive features in MAP chain is that the network is maintained by thousands of relayers and secured by 100+ validators in order to achieve distribution of trust and moving towards increasing decentralization. Due to the vital position of the relayers, all relayers in MAP protocol are incentivised by measuring the work completed.

Relayers will submit the update of interested chains to MAP chain, MAP chain then verify and update corresponding light client. Besides, relayers will also listen to cross-chain tx in target chain and submit tx info via some tx types to notify the chain. The chain will then verify the cross-chain tx message according to the state info of corresponding light client. Besides, relayers can also participate in the on-chain random number generation process by submitting a random number of their own. All random numbers submitted will be merged to forge true on-chain randomness to support various DeFi applications.

What Is Light Client?

Unlike full node, a light client node does not need to query and store tons of information about the blockchain. Light clients normally store only a small set of information that is just enough to verify the status change of the target chain so that they can be updated in a self-verifiable way. Besides, to verify cross-chain messages submitted by relayers, light clients will also store a handful blockchain headers of the target chain.

With the existence of light client, the cross-chain message verification can be done in a pure mathematical way instead of having a federation to verify event on another chain. That is with the trusted Merkel root that usually exists in the blockchain header stored in the light client, the Merkle proof backing up the cross-chain message can be tested. The security of the light client’s state is designed in such a way that it will only be updated by incentive relayers where there is sufficient cryptographic proof following the proof and consensus mechanism of the targeted blockchain, e.g. signatures form enough validators if the target blockchain is PoS and BFT based consensus. Therefore, it formed a strong foundation of cross-chain verification where light clients will be updated by 1000+ relayers through cryptographic proof.

MAP Protocol: Understanding Cross-Chain Communication — Relay & Light Client was originally published in MAP Protocol on Medium, where people are continuing the conversation by highlighting and responding to this story.

Introduction

MAP protocol aims to be the secure end-to-end solution for any blockchain resident to move and exchange assets. To fulfill this role, MAP team is building on three layers simultaneously: a dedicated blockchain served as the infrastructure freeway connecting all kinds of blockchains to break the barriers, the MAP Assets layer where all kinds of assets are mapped to MAP chain in a non-custodial style via trustless smart contract, and the DeFi Application layer where all kinds of applications including but not limited to DEXs, games and NFTs can be built with the cross-chain capabilities enabled by the MAP chain and MAP assets.

MAP Protocol’s bid to reshape the trading experience is supported by a three-layer design:

• App: an application layer driven by an AMM model for decentralized spot exchanges and cross-chain swaps, leading to better liquidity.

• Assets: infrastructure freeway between other blockchains (cross-chain support), allowing assets to move freely between any chains.

• Chain: using a chain dedicated to serving light clients to all interested chains.

Have you heard of recent hack events? Unlike other inter-blockchain communication projects, where mass assets are controlled by a handful of operators, we are building the whole solution in a more trustless and decentralized way. Users’ assets are guarded by transparent and bulletproof smart contracts where the movement of assets can only be triggered by cross-chain messages backed up by valid cryptographic proofs. The verification of the cryptographic proof is based on the light clients maintained by the MAP chain. Using a dedicated blockchain to maintain all the light clients gives MAP protocol the flexibility to integrate necessary features to connect to all kinds of blockchains that might come up.

For example, to interoperate with Cosmos Hub, following the interchain standards specified in github.com/cosmos/ibc, we can build a module for MAP chain to do cross-chain communication, and following the paper “A Tendermint Light Client” by Braithwaite et al., a light client for Cosmos Hub can be built and maintained.

MAP Blockchain

MAP blockchain is a fully EVM compatible blockchain secured by 100+ staked validators via BFT style protocol. MAP chain maintains light clients of all interested blockchains, serving as the solid foundation of cross-chain verification, .e.g. providing the Merkle root for Merkle proof verification.

The correctness of the light client’s state is crucial to the security of MAP protocol. Thus, MAP protocol is designed in a way that the light client’s state will only be updated when there is sufficient cryptographic proof following the proof and consensus mechanism of the target blockchain, e.g., signatures from enough validators if the target blockchain is PoS & BFT-based and the accumulated difficulty if the target blockchain is PoW & Nakamoto consensus-based.

The updates of all light clients are triggered by incentive relayers through submitting interesting information to the chain. Light clients provide the cryptographic trusted root for verifying all kinds of cross-chain messages in a purely mathematical fashion. Besides, relayers can also participate in the on-chain random number generation process by submitting a random number of their own. All random numbers submitted will be merged to forge true on-chain randomness to support various DeFi applications.

Unlike other interoperability-focused blockchain projects, cross-chain assets of MAP protocol are handled in a much more objective and decentralized way. To facilitate transparent and trestles assets vaults, a MAP chain light client is deployed and maintained on all interested blockchains. Cooperating with the light client maintained by the MAP chain, the smart contract serving as the asset vault can only triggered by verifiable cross-chain messages. Upon these vaults, one-stop boundless assets transfer between all connected blockchains is possible by wrapping all assets on MAP chain.

Advantages

Decentralized: secured by 100+ validators and maintained by thousands of relayers.

Trustless: driven only by cryptographic proof other than human decision.

Randomness: unbiased on-chain randomness forged by thousands of. relayers

Feeless: nearly-zero fees for cross-chain assets transfer or swap by MAP token compensation.
