The hardware CPU adopts Secure Boot and Efuse mechanisms, combined with data encryption chips, and its security level is recognized by national-level licensed exchanges. At the same time, the cold wallet also has technologies such as NFC and face/iris recognition, which can be verified and signed simultaneously with smart authorization devices. In the signature process, NexTablen also supports the mobile hot-end APP to complete the financial process of multi-level approval, which is safe, convenient and fast. **Enterprise-level secure storage solution:** NexTablen separates hot wallet encryption and cold and hot ends, and stores multiple cold wallets in multiple places to form a multi-site and multi-center encrypted signature solution. At the same time, NexTablen adopts multiple-signal P2SH and financial privacy BIP32 technologies to encrypt and transmit all data information. In addition, NexTablen has also created multiple signature algorithms such as rate limit, address whitelist, and webhooks, and combined with the financial process system and approval authorization system, it can not only guarantee the security of digital assets in all aspects, but also make the entire deposit and withdrawal process more efficient and efficient. convenient. **The world's top quantitative strategy** NexTablen wealth management products are jointly developed by top financial institutions, asset management teams, and senior cryptocurrency investors from around the world. make. Through quantitative hedging strategies such as cross-market arbitrage, single-market market making, and cross-market market making, stable value-added space can be obtained under low risk. At present, the NexTablen quantitative strategy team manages more than 10,000 BTC (approximately US$100 million) of self-operated funds, contributing more than 1.6% of the transaction volume of the mainstream cryptocurrency trading market. -Intermarket arbitrage Multiple exchanges, risk-free arbitrage between the same trading pairs -Single market arbitrage The same exchange, risk-free arbitrage between different trading pairs -Strategy backtesting Provide multi-dimensional analysis reports for historical data * Trend trading Trend analysis and fully automatic trading under different K-line conditions * Transaction monitoring Provide investors with real-time trading orders and signal reminders -Big data analysis Analyze transaction data, formulate better strategies, and obtain more lucrative profits **Lightning Network 2.0 based on cross-chain technology Realize value cross-chain transfer** NexTablen defines a general-purpose Lightning Network communication protocol for value transfer across heterogeneous blockchain networks. NexTablen users can lock value in the original chain based on the protocol, and extract the value on NexTablen, and then enjoy fast and low-cost transactions; NexTablen's DAPP can complete business across heterogeneous blockchains based on the protocol. **Universal Lightning Network Communication Protocol for Heterogeneous Blockchains** The Bitcoin and Ethereum networks have implemented different Lightning Network communication protocols, and the protocols are not compatible with each other, which makes it difficult for users to Build a Lightning Network channel between heterogeneous blockchain networks. NexTablen defines an abstract value transfer scheme based on cross-chain technology, which is compatible with mainstream blockchain protocols, aims to shield the complexity of different blockchain implementations, and establish a lightning network between heterogeneous blockchains. Original chain value lock NexTablen has developed their own locking smart contracts for different blockchain implementations. When a user establishes a lightning network channel, he will first execute the locked smart contract of the original chain. When this smart contract is executed, NexTablen will lock the value on the original chain with the characteristics of the user, and the original chain needs to be authorized by both NexTablen and the user to redeem the value. NexTablen Value Extraction The value lock contract of the original chain will trigger NexTablen to execute the smart contract of value extraction, and the value extraction contract will trigger the double-entry accounting in the NexTablen system. This form of accounting can accurately and conveniently record the assets of users in the original chain. After the execution of the contract is completed, the user can query the assets on the original chain on the NexTablen blockchain, and can also complete real-time transactions of homogeneous or heterogeneous blockchains based on NexTablen. Fund security Based on technologies such as multi-signature and cold wallet, NexTablen strongly guarantees the security of funds on the user's original chain. In the foreseeable future, NexTablen will continue to upgrade and strengthen security measures to protect users' funds from security risks brought about by hardware or software updates such as quantum calculators and distributed brute force cracking. **Fast and low-cost transactions** Different from the slow and costly value transfer forms on the public chain, users can realize millisecond-level value transfer through NexTablen, and there is no need to pay handling fees. In addition to supporting fast transfer transactions, NexTablen also supports efficient OTC transactions, solving the complexity and trust issues of current OTC transactions. In essence, the transaction form of otc is a currency transaction, the buyer pays the token accepted by the seller, and the seller transfers the token purchased by the buyer. head The two sides of the former otc are matched through a centralized system. The centralized system imposes penalties on both buyers and sellers for breach of contract (such as the number of purchase cancellations cannot exceed a fixed number of times, and the seller will be banned if he does not issue tokens) to ensure the completion of the transaction between the two parties. Even so, centralized otc transactions still face more appeals and rulings. NexTablen expands the characteristics of the lightning network. When the buyer and the seller reach a transaction intention, one party initiates an OTC transaction contract through NexTablen's lightning network mechanism, locks one party's funds in the contract and sends it to the counterparty, and the counterparty receives the contract Lock the tokens that you need to pay in the contract. When both parties lock the tokens constrained by the contract together in the contract, the transaction will be completed immediately, without the need for a centralized system to restrict the buyer and seller. Before the transaction is concluded, the initiator of the contract can cancel the contract at any time, making the flow of funds more flexible. The NexTablen Lightning Network supports all tokens managed by NexTablen, including public chain tokens such as BTC and ETH, as well as business tokens issued by NexTablen. Compared with traditional centralized OTC transactions, using the NexTablen Lightning Network to complete OTC transactions has the characteristics of decentralization, no need to trust counterparties, and flexible funds. Open and transparent blockchain project issuance At present, the token contract on the market is not transparent. Although the white paper explains the distribution plan, there is no specificity in the token contract. The distribution plan and the unfreezing plan are reflected, and relying on offline transfer operations to implement the token unfreezing plan, users can only trust that the token issuer will abide by the unfreezing plan in the white paper. NexTablen has built-in support for a transparent token distribution contract, and the distribution and unfreezing plan of tokens are completely uploaded to the chain. The user's token distribution and token unfreezing plan is set at the beginning of the token issuance, and the built-in token smart contract is generated and solidified on the blockchain. All token distribution and unfreezing plans can be accessed through the business blockchain browser Check that the frozen tokens will not enter the balance of the target account until they meet the requirements of the unfreezing plan. --- # Agent Instructions This documentation is published with GitBook.
