    // echo '[{"jsonrpc":"2.0","method":"blockchain.transaction.get","params":["484a11c5e086a281413b9192b4f60c06abf745f08c2c28c4b4daefe6df3b9e5c", true],"id":1}]' | nc bitkoins.nl  50001 -i 1
    // @see https://electrumx.readthedocs.io/en/latest/protocol-methods.html#blockchain-transaction-get

    // possible solution: fetch it without verbose and decode locally. unfortunatelly it omits such info as confirmations, time etc
    // so whoever uses it should be prepared for this.
    // tbh consumer wallets dont usually work with such big txs, so probably we dont need it
