Since this explorer is database-free, it doesn't natively support address balances and transaction histories. In order to provide this functionality, address balances and transaction history can be requested from a configurable set of ElectrumX servers. If multiple ElectrumX servers are configured, the results are cross-referenced and conflicts noted. For the transaction history displayed below, only the transaction identifiers from ElectrumX are used; the transaction details are requested via RPC from this app's primary node, as usual.
