Abstract: Methods and systems for omni-chain interoperability protocol in omni-chain network is disclosed. The method includes receiving by a first node, an event data from a first blockchain. The method includes attesting the event data based on a Threshold Signature Schemes (TSS) process. The method includes transmitting the attested event data to time nodes on a timechain. Upon receiving the attested event data, the time nodes validate the attested event data. The validated event data is available for a second node on a second blockchain to access. The second node is configured to access the validated event data from timechain, attest the validated event data along with other nodes on the second blockchain, and deploy a second smart contract on the second blockchain. The second smart contract completes a transmission of the validated event data as an ongoing transaction from the first blockchain to the second blockchain.

Abstract: A proof of time (PoT) protocol implemented on a network of nodes to add a block to a timechain is provided. In order to participate in the consensus process, the nodes in the network have to stake a predefined number of tokens with the network. Further, the nodes have to register their participation keys with the network. Thereafter, the nodes of the network are classified into time nodes and time electors. Determination of the nodes which will serve as the time nodes and which will serve as the time electors is done by running a verifiable delay function (VDF) based on a ranking score and fixed stake of each node. The block is added to the timechain in a period called a slot. The network releases a random number called a seed that each node uses to compute VDF based on its ranking score and the fixed stake.

Abstract: A conveyance for surmounting obstacles which includes a first ground engaging arrangement, and a second ground engaging arrangement, and the first and second ground engaging arrangements are operable to move in an alternating sequence of movements to enable the conveyance to surmount obstacles. The conveyance is statically balanced alternately by one then the other of the ground engaging arrangements throughout the sequence of movements. Each ground engaging arrangement includes a forwardly disposed portion and a rearwardly disposed portion which are spaced apart from one another. Each ground engaging arrangement further includes an obstacle accommodating region located between the forwardly disposed portion and the rearwardly disposed portion which can accommodate a portion of an obstacle being surmounted during use.

Abstract: An improved plug device for the drain of a basin or a bathtub, which is comprised of a roller mounted on a rod and spring enclosed by two semicircular sleeves, which when assembled together form a cylindrical sleeve. The roller is guided by a guide groove which is carried on the inner wall of the two semicircular sleeves. The roller is connected to a drain plug by a rod and spring urges the device upwardly. The guide groove has rest positions so that by simply depressing the plug sequentially, the plug is automatically set in either the open or closed position.
