摘要：【中文】本发明提供一种区块链钱包用户身份认证方法及系统，包括：获取创建或导入钱包的设备ID、创建或导入钱包生成的钱包ID列表，分配用于标识设备ID和钱包ID列表的用户ID，并将钱包ID列表中的各钱包ID、设备ID、用户ID建立第一映射关系；获取登录钱包的设备ID、登录钱包的钱包ID列表、登录钱包的手机号，将登录钱包的钱包ID列表中的各钱包ID、登录钱包的设备ID、登录钱包的手机号与对应的用户ID建立第二映射关系；通过第一映射关系和第二映射关系的交叉匹配对多个不同钱包ID的用户身份的唯一性进行认证。通过钱包ID、设备ID、手机号与用户ID形成多对多的映射关系，对一个用户创建多个钱包的身份唯一性进行认证，对区块链钱包的用户身份进行有效管理。 【EN】The invention provides a method and a system for authenticating the identity of a block chain wallet user, comprising the following steps: acquiring a device ID for creating or importing a wallet, and a wallet ID list generated by creating or importing the wallet, allocating user IDs for identifying the device ID and the wallet ID list, and establishing a first mapping relation among each wallet ID, the device ID and the user ID in the wallet ID list; acquiring the equipment ID of the login wallet, a wallet ID list of the login wallet and the mobile phone number of the login wallet, and establishing a second mapping relation between each wallet ID, the equipment ID of the login wallet, the mobile phone number of the login wallet in the wallet ID list of the login wallet and the corresponding user ID; and authenticating the uniqueness of the user identities of the plurality of different wallet IDs through the cross matching of the first mapping relation and the second mapping relation. The identity uniqueness of a user creating a plurality of wallets is authenticated by forming a many-to-many mapping relation among the wallet ID, the equipment ID, the mobile phone number and the user ID, and the user identity of the blockchain wallet is effectively managed.

摘要：【中文】本发明涉及资产账户恢复技术领域，公开了一种区块链资产账户恢复的方法及装置，包括：根据扫描第一数量的助记词碎片所对应的二维码，分别获得所述第一数量中各个助记词碎片所分别对应的坐标信息，其中，所述第一数量的助记词碎片由用于表示区块链资产的助记词碎片化成的第二数量的助记词碎片中所得，所述第一数量小于所述第二数量；根据所述各个助记词碎片所分别对应的坐标信息，计算确定所述助记词所对应的种子；将所述种子还原成对应的助记词，恢复所述区块链资产的账户。解决了现有技术中区块链资产存在丢失信息后给资产拥有者带来极大安全隐患，而且无法做到去中心化的问题。 【EN】The invention relates to the technical field of asset account recovery, and discloses a method and a device for recovering a block chain asset account, which comprise the following steps: respectively obtaining coordinate information corresponding to each mnemonic word fragment in a first quantity according to two-dimensional codes corresponding to the scanned mnemonic word fragments in the first quantity, wherein the mnemonic word fragments in the first quantity are obtained from a mnemonic word fragment in a second quantity formed by fragmenting mnemonic words used for representing block chain assets, and the first quantity is smaller than the second quantity; calculating and determining seeds corresponding to the mnemonics according to the coordinate information corresponding to each mnemonic fragment; and restoring the seeds into corresponding mnemonics, and recovering the account of the block chain assets. The problem of block chain asset have in the prior art and lose and bring very big potential safety hazard for the asset owner after the information, can't accomplish to remove centralization moreover is solved.

摘要：【中文】本发明提供一种区块链钱包签名确权方法、装置及系统，该区块链钱包签名确权方法，包括：客户端在钱包生成时先获取第一公私钥对和第二公私钥对，并使用第一私钥对第二公钥签名得到密钥签名值，保存密钥签名值、第二公私钥对和第一公钥；客户端要求钱包确权时，获取服务端发送的验证码，使用第二私钥对至少包括验证码在内的数据进行签名得到验证码签名值，把包含验证码签名值、密钥签名值、第一公钥和第二公钥在内的数据上传至服务端以供服务端用第一公钥验证密钥签名值来确保第二公钥的有效性，用第二公钥验证验证码签名值来确保验证码的准确性和有效性，用验证码来认证钱包认证的通信过程的安全可信性。本发明安全性高，流程简单。 【EN】The invention provides a method, a device and a system for confirming the signature authority of a block chain wallet, wherein the method for confirming the signature authority of the block chain wallet comprises the following steps: the method comprises the steps that when a wallet is generated, a client side firstly obtains a first public and private key pair and a second public and private key pair, signs a second public key by using a first private key to obtain a key signature value, and stores the key signature value, the second public and private key pair and the first public key; when the client side requires the wallet authority, the verification code sent by the server side is obtained, the second private key is used for signing data at least comprising the verification code to obtain a verification code signature value, the data comprising the verification code signature value, the secret key signature value, the first public key and the second public key are uploaded to the server side so that the server side can verify the secret key signature value by using the first public key to ensure the validity of the second public key, the second public key is used for verifying the verification code signature value to ensure the accuracy and the validity of the verification code, and the verification code is used for authenticating the safety and the credibility of the communication process of wallet authentication. The invention has high safety and simple process.

摘要：【中文】本发明提供了一种5米直径筒段法兰的装配焊接及形位尺寸控制方法，包括在形成封闭的贮箱之前，先在需要焊接法兰的单个目标筒段进行机械开孔并焊接法兰的步骤。本发明所述的5米直径筒段法兰的装配焊接及形位尺寸控制方法，贮箱筒段开孔由整箱状态下手工开孔改进为单个筒段状态下机械开孔，开孔精度提高，为后续保证焊接质量和减小焊接变形奠定了基础。 【EN】The invention provides an assembly welding and form and position size control method of a 5-meter-diameter cylinder section flange, which comprises the steps of mechanically perforating a single target cylinder section needing to be welded with the flange and welding the flange before a closed storage box is formed. According to the method for assembling, welding and controlling the shape, position and size of the 5-meter-diameter cylinder section flange, the manual hole opening of the storage box cylinder section is improved from the manual hole opening in the whole box state to the mechanical hole opening in the single cylinder section state, the hole opening precision is improved, and a foundation is laid for ensuring the welding quality and reducing the welding deformation subsequently.
