Good day! I`m working with low level API to make tx and sign it offline. But after all preparations I try to broadcast it and than i get an error from network: *16: mandatory-script-verify-flag-failed (signature must be zero for failed check(multi)sig operation)*
First of all I create tx without signing inputs, and after that i`m trying to sign every input with my priv keys. *Here is raw tx before signing : * 01000000018bcf82619e93eb92cc78d5bb0b7b22d6ee419820428402e721fbac1386c9673f0000000000ffffffff02087f0300000000001976a9146fb643fe63bcc6c352899298d6072cc5d4178c0f88ace4570000000000001976a914196e59ee4c151e742af69bca308fc1b4445c577288ac00000000 *Parsing tx from the https://live.blockcypher.com/btc/decodetx/ <https://live.blockcypher.com/btc/decodetx/> :* *{ "addresses": [ "16Yb7QP5jVmjXvHawH2ZA66k1b46FmtmE3", "1BBgML68FuyRwU8RzwYn1FvqAXDDSgjVKC", "13KU69194fJj13G1SajUWokudsuekhT1kw" ], "block_height": -1, "block_index": -1, "confirmations": 0, "double_spend": false, "fees": 0, "hash": "1e3c06bfc2f2e91db9059a0db6dd78090f635b869feb31c3d51bc4a36ed88891", "inputs": [ { "addresses": [ "16Yb7QP5jVmjXvHawH2ZA66k1b46FmtmE3" ], "age": 534819, "output_index": 0, "output_value": 251628, "prev_hash": "3f67c98613acfb21e7028442209841eed6227b0bbbd578cc92eb939e6182cf8b", "script_type": "pay-to-pubkey-hash", "sequence": 4294967295 } ], "outputs": [ { "addresses": [ "1BBgML68FuyRwU8RzwYn1FvqAXDDSgjVKC" ], "script": "76a9146fb643fe63bcc6c352899298d6072cc5d4178c0f88ac", "script_type": "pay-to-pubkey-hash", "value": 229128 }, { "addresses": [ "13KU69194fJj13G1SajUWokudsuekhT1kw" ], "script": "76a914196e59ee4c151e742af69bca308fc1b4445c577288ac", "script_type": "pay-to-pubkey-hash", "value": 22500 } ], "preference": "low", "received": "2018-08-05T10:43:36.984631491Z", "relayed_by": "54.234.76.246", "size": 119, "total": 251628, "ver": 1, "vin_sz": 1, "vout_sz": 2}* Here is my code of signing every in: for (int i = 0;
