// 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.
