Block Size Update
How can a blockchain accommodate changing storage requirements?
The size of a block can become a constraint, limiting the scalability of the chain by restricting the number of records that can be concurrently verified and validated.
The record capacity of blocks can be updated to allow blocks to be sized in accordance with application performance requirements.
The block maker mechanism is used to modify the block size and to introduce the new block size to the blockchain network. This can result in a hard fork and the creation of a new blockchain.
Block Maker, Hashing Engine
The primary mechanism involved in the application of this pattern is the block maker. This mechanism is configured when the application is first developed and will need to be further reconfigured if a block size change is necessary. A change to the capacity of a block is considered a hard fork because the new blocks will no longer be compatible with previously created blocks. As a result, the release of a new version of the blockchain application is required.
