Class: MemBlock


Mem Block A block object which is essentially a "placeholder" for a full Block object. The v8 garbage collector's head will explode if there is too much data on the javascript heap. Blocks can currently be up to 1mb in size. In the future, they may be 2mb, 8mb, or maybe 20mb, who knows? A MemBlock is an optimization in Bcoin which defers parsing of the serialized transactions (the block Buffer) until the block has passed through the chain queue and is about to enter the chain. This keeps a lot data off of the javascript heap for most of the time a block even exists in memory, and manages to keep a lot of strain off of the garbage collector. Having 500mb of blocks on the js heap would not be a good thing.
