Transaction – The script was evaluated without errors, but completed with a false/empty top stack element (Electrum throws an error).

There seems to be a problem with the unlock script on input 1.

For input 2your script is 0014DC6BF86354105DE2FCD9868A2B0376D6731CB92F

witch	meaning
00	OP_0
14	OP_PUSH20
DC6BF86354105DE2FCD9868A2B0376D6731CB92F	pushed data

what appears to be standard

But for input Onei believe you did 160014AA6502A44947CF829B41B6D065E04E80F92897A2

witch	meaning
16	OP_PUSH22
0014AA6502A44947CF829B41B6D065E04E80F92897A2	pushed data

I believe the initial byte 0x16 is false and should not be there. Or maybe the previous 0x17 is false and not the length of the script.

The data pushed appears to be intended to be more normal data. OP_0 And push.

Here’s the breakdown of the deal (I hope it’s accurate):

blockchain> txfile tx6.hex
Reading file `tx6.hex` ...

The hexadecimal data is

(0200000002e534266acdc23f944e919ef38d9968c47f9f504c03a57897c0dc2336afec1bf50000000017160014aa6502a44947cf829b41b6d065e04e80f92897a2ffffffff3ba884bc7fc43c5bebb34ed174e2c2b0e866112660649248eef6609db0f5ac1b0b000000160014dc6bf86354105de2fcd9868a2b0376d6731cb92fffffffff01a00f00000000000017a914a7fe1a34561bf3ca04b2f00975aa518012c765298700000000)

The first output is worth 4000 Satoshi

Bitcoin Core seems to parse transactions the same way.
