Abstract: A method for establishing secured connection on an apparatus, comprising: connecting to a network; retrieving a last known block header hash corresponding to a last known block in a last known blockchain; connecting to a plurality of trusted peers via the network; in response to each trusted peer being successfully connected, downloading a latest block header of the trusted peers; based on the last known block header hash, determining whether the latest block header of each trusted peers is referenced to the last known block; and in response to a first number exceeding a threshold number, verifying the latest block header to form a latest version blockchain, wherein the first number is a number of peers in the plurality of trusted peers being successfully connected, and the peers have the latest block header being referenced to the last known block.

Abstract: A blockchain scaling method includes the following operations: determining whether a transaction parameter of a block generating process in an original chain of blocks exceeds a first threshold; and forking the original chain into two sub-chains when the transaction parameter exceeds the threshold, wherein each of the two sub-chains comprises same previous block information corresponding to the original chain and a sub-chain identification.
