Bitcoin Backed Data Availability
Using zkDA as the Data Availability (DA) Layer in your Rollup Stack, you're tapping into Bitcoin.
Syscoin’s BitcoinDA differs from Ethereum’s danksharding in how data is stored, presented, pruned, and how fees are calculated. BitcoinDA has characteristics that make it a valuable alternative to Ethereum’s work-in-progress data availability solution, Proto-Danksharding.
