Abstract: A method and apparatus for block propagation in a blockchain platform. Where multiple nodes establish a peer through a peer-to-peer network and maintain the same blockchain, a node stores information of a first peer transmitted a first forwarding message in a first storage when receiving, from the first peer, which is a node on the network, the first forwarding message including a first portion associated with a block. The node transmits a second forwarding message including the first portion to a second peer that is a node on the network. The node transmits a first request message to the first peer based on information in the first storage, the first request message requesting a second portion associated with the block and corresponding to the first portion. The node receives a third forwarding message including the second portion corresponding to the first request message from the first peer.
