Data Availability is of paramount importance to the secure and resilient functioning of blockchains. Data Availability problems fall into two categories; One set of problems is the availability of current blocks, to enable clients to validate transactions. The other is the historical ledger data availability; Some may call this a problem of data retrievability instead of data availability, but we choose to use the same terminology for both.
Doge Protocol blockchain will be a combined multi-fork of Bitcoin, Ethereum, Doge Coin and DogeP. These blockchains which Doge Protocol will multi-fork are three of the largest. Because of this, the ledger size of Doge Protocol will be huge, to begin with, after the multi-fork. Hence data availability is critical to the Doge Protocol blockchain, to make it more secure and resilient.
