Introduction¶
SCA is the utility token that powers the Blocknet Protocol. Fees are paid in SCA when using the network and 100% of those fees are distributed to Service Nodes for supporting the network and infrastructure. Normal transaction fees on the network are also paid in SCA and awarded to stakers. If seeking to acquire SCA, there are various options available.

Scaling¶
The Blocknet Protocol is fast and the capacity of the protocol increases with its user base. Since order broadcast and order matching are completely decentralized, there are no bottlenecks other than the ones which lie with users, namely their local internet connections. In addition though, there is a shared capacity in the broadcasting system, which is extremely high. Here is a relevant quotation from a Bitcoin wiki:
Bitcoin Wiki
Let's assume an average rate of 2000tps, so just VISA. Transactions vary in size from about 0.2 kilobytes to over 1 kilobyte, but it's averaging half a kilobyte today.
That means that you need to keep up with around 8 megabits/second of transaction data (2000tps * 512 bytes) / 1024 bytes in a kilobyte / 1024 kilobytes in a megabyte = 0.97 megabytes per second * 8 = 7.8 megabits/second.
This sort of bandwidth is already common for even residential connections today, and is certainly at the low end of what colocation providers would expect to provide you with.
When blocks are solved, the current protocol will send the transactions again, even if a peer has already seen it at broadcast time. Fixing this to make blocks just list of hashes would resolve the issue and make the bandwidth needed for block broadcast negligible. So whilst this optimization isn't fully implemented today, we do not consider block transmission bandwidth here.
SCA Inflation¶
While there is no maximum limit due to the Scalaris blockchain being Proof of Stake, there is a limit to the amount that can be minted per period (limited inflation). This means that over time the inflation rate decreases as the circulation increases and the amount of SCA minted remains constant.
