Calculating Number of Transactions That Can Be Stored
The number of transactions that can be stored is determined by the size of the transaction.
Each transaction minimally has 45 bytes as header data and has up to 4KB of transaction
data.
A transaction looks as follows:
[45 Bytes – Header] [Up to 4KB Data]
To calculate the number of transactions that can be stored, you can use the following
calculation:
1,048,576 / (45 + <data length> )
For example, if you were simply using 10-digit badges, the calculation would appear as
follows:
1,048,576 / (45 + 10) = 19065
