+// This tool looks at the last 10 VAAs on each chain and tells you how many signatures each guardian has among those 10 VAAs.
+// Wormscan is used as the datasource.
+// If a timestamp is provided as argument, only VAAs after this timestamp are considered.
+// For example, an output of
+// 	solana:	map[0:7 1:10 2:10 3:5 4:10 6:10 9:7 10:10 11:5 13:9 14:10 15:8 16:10 17:10 18:10]
+// means that on Solana, the Guardian with index 0 had its signature included in 7 out of 10 VAAs.
+// Because Guardians usually do not collect more than 13 signatures on one VAA,
+// it is expected that not every Guardian has a signature in every VAA and low participation rate is not necessarily indicative of a problem.
