Apparatus and method for establishing secured connection

An apparatus for establishing secured connection comprising:

• a memory configured to store computer readable instructions and a last known block header hash corresponding to a last known block in a last known blockchain;
• and
• a processor electrically coupled to the memory and configured to retrieve the computer readable instructions to execute at least the following steps:
• connecting to a network;
• retrieving the last known block header hash;
• connecting to a plurality of trusted peers via the network;
• in response to each of the plurality of trusted peers being successfully connected, downloading a latest block header of the trusted peers being connected respectively;
• based on the last known block header hash, determining whether the latest block header of each of the plurality of trusted peers is referenced to the last known block;
• and
• in response to a first number exceeding a threshold number, stopping the step of connecting to the plurality of trusted peers and going to a verification step to verifying the latest block header to form a current version blockchain extending from the last known blockchain,
• wherein the first number is a number of first peers in the plurality of trusted peers being successfully connected, and the first peers have the latest block header being referenced to the last known block.
