# 4.5 SatoshiChain Configurations

* The average block time is expected to be 2 seconds. 
* Initially, 21 nodes will be running to comply with BFT (Byzantine Fault Tolerance). 
* Block size will be dynamic and decided by the Validator set. The initial block gas limit is 30,000,000. 
* The expected number of validator nodes in the chain will be 21 at a minimum. 
* Any account staking more than 10,000,000 $SC tokens and passing the community authority and authentication, will be allowed to join the Validator Set. 
* SatoshiChain has pre-deployed contracts for staking. This allows for the staking of $SC tokens, providing rewards to holders. 
* If the block is not produced or accepted within the expected time, the next validator would take over the proposer duty. 
* There is no newly minted block reward for block production. 
* All transaction fees will be valued in either $SAT or $SC.
