getmempooldescendants "txid" ( verbose )
If txid is in the mempool, returns all in-mempool descendants.
Arguments:
1. txid (string, required) The transaction id (must be in mempool)
2. verbose (boolean, optional, default=false) True for a json object, false for array of transaction ids
Result (for verbose = false):
[ (json array of strings)
"transactionid" (string) The transaction id of an in-mempool descendant transaction
,...
]
Result (for verbose = true):
{ (json object)
"transactionid" : { (json object)
"vsize" : n, (numeric) virtual transaction size as defined in BIP 141. This is different from actual serialized size for witness transactions as witness data is discounted.
"size" : n, (numeric) (DEPRECATED) same as vsize. Only returned if bitcoind is started with -deprecatedrpc=size
size will be completely removed in v0.20.
"weight" : n, (numeric) transaction weight as defined in BIP 141.
"fee" : n, (numeric) transaction fee in BTC (DEPRECATED)
"modifiedfee" : n, (numeric) transaction fee with fee deltas used for mining priority (DEPRECATED)
"time" : n, (numeric) local time transaction entered pool in seconds since 1 Jan 1970 GMT
"height" : n, (numeric) block height when transaction entered pool
"descendantcount" : n, (numeric) number of in-mempool descendant transactions (including this one)
"descendantsize" : n, (numeric) virtual transaction size of in-mempool descendants (including this one)
"descendantfees" : n, (numeric) modified fees (see above) of in-mempool descendants (including this one) (DEPRECATED)
"ancestorcount" : n, (numeric) number of in-mempool ancestor transactions (including this one)
"ancestorsize" : n, (numeric) virtual transaction size of in-mempool ancestors (including this one)
"ancestorfees" : n, (numeric) modified fees (see above) of in-mempool ancestors (including this one) (DEPRECATED)
"wtxid" : hash, (string) hash of serialized transaction, including witness data
"fees" : {
"base" : n, (numeric) transaction fee in BTC
"modified" : n, (numeric) transaction fee with fee deltas used for mining priority in BTC
"ancestor" : n, (numeric) modified fees (see above) of in-mempool ancestors (including this one) in BTC
"descendant" : n, (numeric) modified fees (see above) of in-mempool descendants (including this one) in BTC
}
"depends" : [ (array) unconfirmed transactions used as inputs for this transaction
"transactionid", (string) parent transaction id
... ]
"spentby" : [ (array) unconfirmed transactions spending outputs from this transaction
"transactionid", (string) child transaction id
... ]
"bip125-replaceable" : true|false, (boolean) Whether this transaction could be replaced due to BIP125 (replace-by-fee)
