 ## SEQ Validators:
 - SEQ validators register with arcadia to receive chunks for preconfing.
 - SEQ validators check few assertions on chunks, and issue a chunk cert if the assertions are satisfied. 
 - Valdiators store the signature verified txs in a emap, to prevent duplicate txs and ease signature verification while accepting the block.
-- SEQ blocks are produced every 2 seconds, validators fetch `SEQMsg` txs payload from arcadia to get included in the SEQ block and fill the rest of the block with `non SEQMsg` txs.
+- SEQ blocks are produced every 2 seconds, validators fetch `SequencerMsg` txs payload from arcadia to get included in the SEQ block and fill the rest of the block with `non SequencerMsg` txs.
