The method being mainly provided to achieve segmenting locking and merging control of encrypted digital assets by adding a time attribute to encrypted digital asset. Using the method for performing segmenting locking and merging control of encrypted digital assets based on time dimension of the present invention, through the processing of encrypted digital assets in the time dimension, which not only can use smart contracts or hash locking to realize the automated transfer of encrypted digital assets in the future, and the transferred encrypted digital asset before the set time, also can transfer and transaction; meanwhile, since the segmentation object is based on the assets currently held by the user, therefore the deterministic payment of future value rights also can be ensured, has a wider range of applications. ## Claims ### Claim 1 A method for performing segmenting locking of encrypted digital assets based on time dimension, the method comprising: storing on a first user terminal a first encrypted digital asset (N, M) of a type of currency N and an amount of the currency M in a first data structure of the first user terminal; adding attributes for an overall time period interval (T1, T2) of the first encrypted digital asset (N, M) to a second data structure of the first user terminal, in order to expand the first encrypted digital asset (N, M) into a second encrypted digital asset (N, M, T1, T2) having attributes for the overall time period interval (T1, T2), where T1 is a start timestamp of a user's possession of the digital asset (N, M) and T2 is an end timestamp of the user's possession of the digital asset (N, M); separating, based on the second data structure, the first user terminal's ownership related to the first encrypted digital asset (N, M) in the overall time period interval (T1, T2) into a right to use of a second user terminal related to the first encrypted digital asset (N, M) in a first time period interval (T1, P), and the first user terminal's ownership of the first encrypted digital asset (N, M) in a second time period interval (P+1, T2), wherein the first time period interval (T1, P) spans between the start timestamp T1 of a user's possession of the digital asset (N, M) and an intervening timestamp P that is between the start timestamp T1 and the end timestamp T2, wherein the second time period interval (P+1, T2) spans between a second after the intervening timestamp P and the end timestamp T2, and wherein the start timestamp T1, the intervening timestamp P, and the end timestamp T2 are any positive integers, and the T1
