Block chain system-based digital asset transaction method and block chain system

The invention discloses a block chain system-based digital asset transaction method and a block chain system. The block chain system is a tree-shaped distributed block chain system including a plurality of levels of block chains. The method comprises the following steps that: a first block chain receives a digital asset transaction request from a client, and determines digital assets corresponding to the digital asset transaction request; whether an attribution block chain corresponding to the digital assets is a first block chain is judged; if the attribution block chain corresponding to the digital assets is the first block chain, the first block chain processes the digital asset transaction request; and if the attribution block chain corresponding to the digital assets is not the first block chain, the first block chain rejects the digital asset transaction request, wherein the attribution block chain corresponding to the digital assets is a block chain that generates the digital assets. The method is especially suitable for the transactions of one-time one-use digital assets, wherein the digital assets can be only used once; and moreover, the method can also realize a cross-chain transactions between the digital assets, and the digital assets are corresponding to different attribution block chains before and after the cross-chain transactions are executed, and therefore, the security of the assets can be improved.

Terse message networks

A tree-shaped mesh network is discussed which uses a mesh of wireless nodes that form a tree shaped network with one root node having a connection to an external network; chirp clients; and wireless network clients. Chirp clients comprise low cost chirp devices wherein said low cost chirp devices transmit short duration messages wherein transmission of said short duration messages are scheduled at preset transmission intervals. At least one wireless node of the mesh of wireless nodes is a designated chirp-aware node wherein said chirp-aware node sets the preset transmission intervals for chirp client communication by broadcasting a beacon prior to transmission by chirp clients and said chirp-aware node further comprises a bridge between the short duration messages and IP based devices wherein said bridge includes a wireless receiver to receive the short duration messages and is connected to said external network. The short duration messages are encapsulated into action frames, for onward transmission to other chirp aware routers. Each wireless node further comprises two logical radios and a service radio wherein each wireless node uplink and downlink operates on distinct non-conflicting frequencies. The wireless network clients communicate with the wireless nodes using node service radios.

Compression of nodes in a trie structure

The invention relates to a method for implementing a functional memory and to a memory arrangement. The memory is implemented as a directory structure comprising a tree-shaped hierarchy having nodes at several different hierarchy levels, wherein an individual node can be (i) a trie node associated with a logical table wherein an individual element may contain a pointer pointing to a lower node in the hierarchy, or (ii) a bucket containing at least one element so that the type of an individual element in the bucket is selected from a group including of e.g. a data unit or a pointer to a stored data unit. To optimize the performance of the functional trie structure, the trie nodes are implemented as quad nodes of four elements, and in at least part of the directory structure groups of successive quad nodes are replaced by compressed nodes in such a way that (a) an individual group comprising a given quad node and its child nodes is replaced by a node whose logical table has 16 elements, and (b) a compressed node known per se is formed from said node of 16 elements by physically storing in the node only non-nil pointers and in addition a bit pattern on the basis of which the physical storage location in the node, corresponding to the search word, can be determined. The invention also relates to a structure in which no buckets are used.

Novel shed frame pear tree shape and reshaping method thereof

The invention provides a pear tree two-arm direct-motion type shed frame tree shape which comprises a tree trunk. The tree trunk has two boughs which grow in a direct-motion mode, and base angles of the two boughs are 45 degrees. When reaching a frame-climbing point, the boughs are fixed on a horizontal shed frame in a direct-motion mode, and extended long branches of the boughs are guided onto an elevation guide line in a perpendicular mode. The boughs have long placed fruit branches which are arranged in parallel and vertically extend into intervals. Before the two boughs climb a frame, two horizontal robust side position branches which are pulled along the reverse direction to be parallel to the boughs after the horizontal robust side position branches grow upward to the frame face. The side position branches have F-shaped single-shaft long placed type fruit branches which are arranged in parallel and vertically extend to the intervals. The tree shape only has the two boughs, and therefore the problems that an inclined crown appears easily in a three-bough tree shape and the main boughs intersect are solved. The two boughs oppositely extend in a direct-motion mode and do not influence each other. The two-bough tree shape is easy to reshape, and the two boughs are easy to form after the trunk is fixed. The phenomenon of lack of branches appears in a three-bough shed frame due to the fact that sprout force of a pear tree is weak. The three shape has the advantages that cultivation density is high, early-stage output is high, light conditions are good, the branches are easy to arrange in an ordered mode, uniformity of fruit quality is high, and standardization is easy to achieve.
