Problems solved by technology

[0003] Many existing mainstream exchanges or APP wallets have great security risks, because the wallet addresses and account passwords generated on the platform are stored on the platform server, which is very unsafe. If hacked or the platform runs away, then The user's digital currency will cease to exist

Embodiment 1

[0034] This embodiment provides a decentralized cross-chain transfer in and out method, such as figure 1 shown, including the following steps:

[0035] S1, communication between the platform chain and other main chains through cross-chain adapters;

[0036] S2, create a decentralized master account in the hardware wallet of the platform chain, and store the master account address, private key and mnemonic when creating the master account locally;

[0037] S3, the cross-chain adapter sets the corresponding sub-account address for the main account of the platform chain on other main chains;

[0038] S4. When performing cross-chain transfers between the main account address and the sub-account address, the cross-chain adapter verifies and confirms the transferred assets, and maps out the platform assets of the platform chain after the transfer is successful.

[0039] In this embodiment, the platform chain of this embodiment and other chains (such as BTC, ETH, etc.) belong to di...

Embodiment 2

[0051] This embodiment provides a decentralized cross-chain transfer-in and transfer-out system, such as figure 2 shown, including hardware wallets and cross-chain adapters;

[0052] The hardware wallet is used to create a decentralized master account in the hardware wallet of the platform chain, and store the master account address, private key and mnemonic when creating the master account locally;

[0053] The cross-chain adapter is used for communication between the platform chain and other main chains; it is used to set corresponding sub-account addresses for the main account of the platform chain on other main chains; cross-link between the main account address and the sub-account address During the chain transfer, it is used to verify and confirm the transferred assets, and map the platform assets of the platform chain after the transfer is successful.

[0054] In this embodiment, the platform chain of this embodiment and other chains (such as BTC, ETH, etc.) belong to...

Abstract

The invention belongs to the technical field of asset management and blockchain, and particularly relates to a decentralized cross-chain roll-in and roll-out method and system, and the method comprises the following steps: enabling a platform chain to communicate with other main chains through a cross-chain adapter; creating a decentralized main account in a hardware wallet of the platform chain,and storing a main account address, a private key and a mnemonic word when the main account is created locally; enabling the cross-chain adapter to set corresponding auxiliary account addresses on other main chains for the main account of the platform chain; when cross-chain account transfer is carried out between the main account address and the auxiliary account address, enabling the cross-chainadapter to verify and confirm the transferred assets, and mapping the platform assets of the platform chain after successful account transfer. According to the invention, the technology of combiningthe hardware wallet and the cross-chain adapter is adopted, the safety of asset management is improved through the hardware wallet, and the transfer-in and transfer-out of assets between different blockchains are realized through the cross-chain adapter, so the safe and convenient management of multi-chain asset transactions is realized.

Description

technical field [0001] The invention belongs to the technical fields of asset management and blockchain, and in particular relates to a decentralized cross-chain transfer-in and transfer-out method and system. Background technique [0002] Blockchain is a term in the field of information technology. In essence, it is a shared database, and the data or information stored in it has the characteristics of "unforgeable", "retaining traces throughout the process", "traceable", "open and transparent", and "collective maintenance". Therefore, the existing blockchain technology has been applied to all walks of life. [0003] Many existing mainstream exchanges or APP wallets have great security risks, because the wallet addresses and account passwords generated on the platform are stored on the platform server, which is very unsafe. If hacked or the platform runs away, then The user's digital currency will cease to exist. Therefore, the present invention combines hardware wallet a...
