MT103.STP
SWIFT ISO15022 Standard
Detail view for message MT103.STP - Single Customer Credit Transfer
Description of the message MT103.STP
MT 103 STP Single Customer Credit Transfer
The MT 103 STP is a general use message, that is, no registration in a Message User Group is necessary to send and receive this message. It allows the exchange of single customer credit transfers using a restricted set of fields and format options of the core MT 103 to make it straight through processable. The MT 103 STP is a compatible subset of the core MT 103 that is documented separately.
The differences with the core MT 103 are:
appropriate MT 103 STP format validation is triggered by the code STP in the validation flag field 119 ({3:{119: STP}}) of the user header of the message (block 3)
fields 52, 54, 55, 56 and 57 may only be used with letter option A
field 53 may only be used with letter options A and B
field 51A is not used in MT 103 STP. This message may only be used on the FIN SWIFT network since it requires special validation
field 23E may only contain codes CORT, INTC, SDVA and REPA
if field 53a is used with option B, Party Identifier must be used
subfield 1 (Account) of field 59a is always mandatory
field 72, code INS must be followed by a valid financial institution BIC
field 72, codes REJT/RETN must not be used
field 72 must not include ERI information.
Important!
To trigger the MT 103 STP format validation, the user header of the message (block 3) is mandatory and must contain the code STP in the validation flag field 119 ({3:{119:STP}}).
Purpose of the message MT103.STP
Instructs a funds transfer
Scope of the message MT103.STP
This message type is sent by or on behalf of the financial institution of the ordering customer, directly or through (a) correspondent(s), to the financial institution of the beneficiary customer.
It is used to convey a funds transfer instruction in which the ordering customer or the beneficiary customer, or both, are non-financial institutions from the perspective of the Sender.
This message may only be used for clean payment instructions. It must not be used to advise the remitting bank of a payment for a clean, for example, cheque, collection, nor to provide the cover for a transaction whose completion was advised separately, for example, via an MT 400.

1. Introduction
When trasmitting data, it can be useful to encode the data in a way that survives lower fidelity transmission mechanisms. For example, encoding data using a human alphabet in a way that a person can visually confirm the encoded data can be more beneficial than encoding it in binary form. The Base58 encoding scheme is similar to the Base64 encoding scheme in that it can translate any binary data to a text string. It is different from Base64 in that the conversion alphabet has been carefully picked to work well in environments where a person, such as a developer or support technician, might need to visually confirm the information with low error rates.
Base58 is designed with a number of usability characteristics in mind that Base64 does not consider. First, similar looking letters are omitted such as 0 (zero), O (capital o), I (capital i) and l (lower case L). Doing so eliminates the possibility of a human being mistaking similar characters for the wrong character. Second, the non-alphanumeric characters + (plus), = (equals), and / (slash) are omitted to make it possible to use Base58 values in all modern file systems and URL schemes without the need for further system-specific encoding schemes. Third, by using only alphanumeric characters, easy double-click or double tap selection is possible in modern computer interfaces. Fourth, social messaging systems do not line break on alphanumeric strings making it easier to e-mail or message Base58 values when debugging systems. Fifth, unlike Base64, there is no byte padding making many Base58 values smaller (on average) or the same size as Base64 values for values up to 64 bytes, and less than 2% larger for larger values. Finally, Base64 has eleven encoding variations that lead to confusion among developers on which variety of Base64 to use. This specification asserts that there is just one simple encoding mechanism for Base58, making implementations and developer interactions simpler.
While Base58 does have a number of beneficial usability features, it is not always a good choice for an encoding format. For example, when encoding large amounts of data, it is 2% less efficient than base64. Developers might avoid Base58 if a 2% increase in efficiency over large data sets is desired.
This document specifies the base 58 encoding scheme, including an introduction to the benefits of the approach, the encoding and decoding algorithm, alternative alphabets, and security considerations.
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
2. The Base58 Alphabet
The Base58 alphabet consists of the following characters:
123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyzEach byte value from 0 to 57 maps to the alphabet above in the following way:
Base58 Mapping Table Byte Character Byte Character Byte Character Byte Character
0 1 1 2 2 3 3 4
4 5 5 6 6 7 7 8
8 9 9 A 10 B 11 C
12 D 13 E 14 F 15 G
16 H 17 J 18 K 19 L
20 M 21 N 22 P 23 Q
24 R 25 S 26 T 27 U
28 V 29 W 30 X 31 Y
32 Z 33 a 34 b 35 c
36 d 37 e 38 f 39 g
40 h 41 i 42 j 43 k
44 m 45 n 46 o 47 p
48 q 49 r 50 s 51 t
52 u 53 v 54 w 55 x
56 y 57 z
Other application-specific alphabets for Base58, such as the Ripple alphabet and the Flickr alphabet exist. Those alphabets, while valid in their own application spaces, are not valid encoding formats for this specification and MUST NOT be used. Supporting more than one Base58 encoding alphabet would harm interoperability.
3. The Base58 Encoding Algorithm
To encode an array of bytes to a Base58 encoded value, run the following algorithm. All mathematical operations MUST be performed using integer arithmetic. Start by initializing a 'zero_counter' to zero (0x0), an 'encoding_flag' to zero (0x0), a 'b58_bytes' array, a 'b58_encoding' array, and a 'carry' value to zero (0x0). For each byte in the array of bytes and while 'carry' does not equal zero (0x0) after the first iteration:
If 'encoding_flag' is not set, and if the byte is a zero (0x0), increment the value of 'zero_counter'. If the value is not zero (0x0), set 'encoding_flag' to true (0x1).
If 'encoding_flag' is set, multiply the current byte value by 256 and add it to 'carry'.
Set the corresponding byte value in 'b58_bytes' to the value of 'carry' modulus 58.
Set 'carry' to the value of 'carry' divided by 58.
Once the 'b58_bytes' array has been constructed, generate the final 'b58_encoding' using the following algorithm. Set the first 'zero_counter' bytes in 'b58_encoding' to '1'. Then, for every byte in 'b58_array', map the byte value using the Base58 alphabet in the previous section to its corresponding character in 'b58_encoding'. Return 'b58_encoding' as the Base58 representation of the input array of bytes.
4. The Base58 Decoding Algorithm
To decode a Base58 encoded array of bytes to a decoded array of bytes, run the following algorithm. All mathematical operations MUST be performed using integer arithmetic. Start by initializing a 'raw_bytes' array, and a 'carry' value to zero (0x0). For each input byte in the array of input bytes:
Set 'carry' to the byte value associated with the input byte character. If a mapping does not exist, return an error code.
While 'carry' does not equal zero and there are input bytes remaining:
Multiply the input byte value by 58 and add it to 'carry'.
Set the output byte value to 'carry' modulus 256.
Set 'carry' to the value of 'carry' divided by 256.
Set the corresponding byte value in 'raw_bytes' to the value of 'carry' modulus 58.
Set 'carry' to the value of 'carry' divided by 58.
5. Test Vectors
The following examples can be used as test vectors for the algorithms in this specification:
2NEpo7TZRRrLZSi2UThe Base58 encoded value for "Hello World!" is:
USm3fpXnKG5EUBx2ndxBDMPVciP5hGey2Jh4NDv6gmeo1LkMeiKrLJUUBk6ZThe Base58 encoded value for "The quick brown fox jumps over the lazy dog." is:
111233QC4The Base58 encoded value for 0x0000287fb4cd is:

7. Security Considerations
Authors' Addresses
++++++++++++
Hello BTC Devs,
Just wanted to know how much difference it makes between "BASE58 (P2SH) & BECH32 (P2WPKH)"
security wise as well as anonymity wise does BECH32 (P2WPKH) really sound than BASE58 (P2SH) ?
Base-58 and bech32 are two encoding schemes. P2WPKH and P2SH are two kinds of transactions.

P2WPKH
this script is similar to P2PKH (addresses starting with 1) but using Segregated Witness. it is also referred to as native SegWit address. it requires one signature and is currently (version 0) using the same signature scheme (ECDSA) as always.
the transaction size is almost the same size as P2PKH (±2 byte) but has a smaller weight so you end up paying lower fees.
- P2WPKH addresses start with bc1 as they use bech32 encoding
the only problem you may face when using these address types is when the person wanting to send coins to you doesn't accept this type of address. eg. an exchange that has not yet updated their system after 3 years!
P2SH
is pay to script where the script can be anything. examples are multi-signature scripts, lock time scripts, witness redeem script,...
if you are looking into "nested SegWit" where you have an address starting with 3 but it is using SegWit then the correct term for these scripts are:
P2SH-P2WPKH
they are similar to P2PKH and they require only one signature.
P2SH-P2WSH
they are similar to regular P2SH but with SegWit. they require a "script" called redeem script to unlock.
- all P2SH addresses start with 3 as they use base58 encoding
in both cases the transaction size is moderately larger than their counterparts due to the leftover redeemscript and SegWit overhead but their weight is smaller so you end up paying a lower fee.
the benefit of nested SegWit compared to native SegWit
--------------------------------------------------------------------------------
there is absolutely no difference between these scripts and their SegWit counterparts regarding anonymity or security (at least not on version 0 witness, there will be some additional privacy benefits in future versions with new proposals).

Base-58 and bech32 are two encoding schemes. P2WPKH and P2SH are two kinds of transactions.
Thanks!

MT103.STP
SWIFT ISO15022 Standard
Detail view for message MT103.STP - Single Customer Credit Transfer
Description of the message MT103.STP
MT 103 STP Single Customer Credit Transfer
The MT 103 STP is a general use message, that is, no registration in a Message User Group is necessary to send and receive this message. It allows the exchange of single customer credit transfers using a restricted set of fields and format options of the core MT 103 to make it straight through processable. The MT 103 STP is a compatible subset of the core MT 103 that is documented separately.
The differences with the core MT 103 are:
appropriate MT 103 STP format validation is triggered by the code STP in the validation flag field 119 ({3:{119: STP}}) of the user header of the message (block 3)
fields 52, 54, 55, 56 and 57 may only be used with letter option A
field 53 may only be used with letter options A and B
field 51A is not used in MT 103 STP. This message may only be used on the FIN SWIFT network since it requires special validation
field 23E may only contain codes CORT, INTC, SDVA and REPA
if field 53a is used with option B, Party Identifier must be used
subfield 1 (Account) of field 59a is always mandatory
field 72, code INS must be followed by a valid financial institution BIC
field 72, codes REJT/RETN must not be used
field 72 must not include ERI information.
Important!
To trigger the MT 103 STP format validation, the user header of the message (block 3) is mandatory and must contain the code STP in the validation flag field 119 ({3:{119:STP}}).
Purpose of the message MT103.STP
Instructs a funds transfer
Scope of the message MT103.STP
This message type is sent by or on behalf of the financial institution of the ordering customer, directly or through (a) correspondent(s), to the financial institution of the beneficiary customer.
It is used to convey a funds transfer instruction in which the ordering customer or the beneficiary customer, or both, are non-financial institutions from the perspective of the Sender.
This message may only be used for clean payment instructions. It must not be used to advise the remitting bank of a payment for a clean, for example, cheque, collection, nor to provide the cover for a transaction whose completion was advised separately, for example, via an MT 400.

1. Introduction
When trasmitting data, it can be useful to encode the data in a way that survives lower fidelity transmission mechanisms. For example, encoding data using a human alphabet in a way that a person can visually confirm the encoded data can be more beneficial than encoding it in binary form. The Base58 encoding scheme is similar to the Base64 encoding scheme in that it can translate any binary data to a text string. It is different from Base64 in that the conversion alphabet has been carefully picked to work well in environments where a person, such as a developer or support technician, might need to visually confirm the information with low error rates.
Base58 is designed with a number of usability characteristics in mind that Base64 does not consider. First, similar looking letters are omitted such as 0 (zero), O (capital o), I (capital i) and l (lower case L). Doing so eliminates the possibility of a human being mistaking similar characters for the wrong character. Second, the non-alphanumeric characters + (plus), = (equals), and / (slash) are omitted to make it possible to use Base58 values in all modern file systems and URL schemes without the need for further system-specific encoding schemes. Third, by using only alphanumeric characters, easy double-click or double tap selection is possible in modern computer interfaces. Fourth, social messaging systems do not line break on alphanumeric strings making it easier to e-mail or message Base58 values when debugging systems. Fifth, unlike Base64, there is no byte padding making many Base58 values smaller (on average) or the same size as Base64 values for values up to 64 bytes, and less than 2% larger for larger values. Finally, Base64 has eleven encoding variations that lead to confusion among developers on which variety of Base64 to use. This specification asserts that there is just one simple encoding mechanism for Base58, making implementations and developer interactions simpler.
While Base58 does have a number of beneficial usability features, it is not always a good choice for an encoding format. For example, when encoding large amounts of data, it is 2% less efficient than base64. Developers might avoid Base58 if a 2% increase in efficiency over large data sets is desired.
This document specifies the base 58 encoding scheme, including an introduction to the benefits of the approach, the encoding and decoding algorithm, alternative alphabets, and security considerations.
1.1. Requirements Language
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119.
2. The Base58 Alphabet
The Base58 alphabet consists of the following characters:
123456789ABCDEFGHJKLMNPQRSTUVWXYZabcdefghijkmnopqrstuvwxyzEach byte value from 0 to 57 maps to the alphabet above in the following way:
Base58 Mapping Table Byte Character Byte Character Byte Character Byte Character
0 1 1 2 2 3 3 4
4 5 5 6 6 7 7 8
8 9 9 A 10 B 11 C
12 D 13 E 14 F 15 G
16 H 17 J 18 K 19 L
20 M 21 N 22 P 23 Q
24 R 25 S 26 T 27 U
28 V 29 W 30 X 31 Y
32 Z 33 a 34 b 35 c
36 d 37 e 38 f 39 g
40 h 41 i 42 j 43 k
44 m 45 n 46 o 47 p
48 q 49 r 50 s 51 t
52 u 53 v 54 w 55 x
56 y 57 z
Other application-specific alphabets for Base58, such as the Ripple alphabet and the Flickr alphabet exist. Those alphabets, while valid in their own application spaces, are not valid encoding formats for this specification and MUST NOT be used. Supporting more than one Base58 encoding alphabet would harm interoperability.
3. The Base58 Encoding Algorithm
To encode an array of bytes to a Base58 encoded value, run the following algorithm. All mathematical operations MUST be performed using integer arithmetic. Start by initializing a 'zero_counter' to zero (0x0), an 'encoding_flag' to zero (0x0), a 'b58_bytes' array, a 'b58_encoding' array, and a 'carry' value to zero (0x0). For each byte in the array of bytes and while 'carry' does not equal zero (0x0) after the first iteration:
If 'encoding_flag' is not set, and if the byte is a zero (0x0), increment the value of 'zero_counter'. If the value is not zero (0x0), set 'encoding_flag' to true (0x1).
If 'encoding_flag' is set, multiply the current byte value by 256 and add it to 'carry'.
Set the corresponding byte value in 'b58_bytes' to the value of 'carry' modulus 58.
Set 'carry' to the value of 'carry' divided by 58.
Once the 'b58_bytes' array has been constructed, generate the final 'b58_encoding' using the following algorithm. Set the first 'zero_counter' bytes in 'b58_encoding' to '1'. Then, for every byte in 'b58_array', map the byte value using the Base58 alphabet in the previous section to its corresponding character in 'b58_encoding'. Return 'b58_encoding' as the Base58 representation of the input array of bytes.
4. The Base58 Decoding Algorithm
To decode a Base58 encoded array of bytes to a decoded array of bytes, run the following algorithm. All mathematical operations MUST be performed using integer arithmetic. Start by initializing a 'raw_bytes' array, and a 'carry' value to zero (0x0). For each input byte in the array of input bytes:
Set 'carry' to the byte value associated with the input byte character. If a mapping does not exist, return an error code.
While 'carry' does not equal zero and there are input bytes remaining:
Multiply the input byte value by 58 and add it to 'carry'.
Set the output byte value to 'carry' modulus 256.
Set 'carry' to the value of 'carry' divided by 256.
Set the corresponding byte value in 'raw_bytes' to the value of 'carry' modulus 58.
Set 'carry' to the value of 'carry' divided by 58.
5. Test Vectors
The following examples can be used as test vectors for the algorithms in this specification:
2NEpo7TZRRrLZSi2UThe Base58 encoded value for "Hello World!" is:
USm3fpXnKG5EUBx2ndxBDMPVciP5hGey2Jh4NDv6gmeo1LkMeiKrLJUUBk6ZThe Base58 encoded value for "The quick brown fox jumps over the lazy dog." is:
111233QC4The Base58 encoded value for 0x0000287fb4cd is:

7. Security Considerations
Authors' Addresses
++++++++++++
Hello BTC Devs,
Just wanted to know how much difference it makes between "BASE58 (P2SH) & BECH32 (P2WPKH)"
security wise as well as anonymity wise does BECH32 (P2WPKH) really sound than BASE58 (P2SH) ?
Base-58 and bech32 are two encoding schemes. P2WPKH and P2SH are two kinds of transactions.

P2WPKH
this script is similar to P2PKH (addresses starting with 1) but using Segregated Witness. it is also referred to as native SegWit address. it requires one signature and is currently (version 0) using the same signature scheme (ECDSA) as always.
the transaction size is almost the same size as P2PKH (±2 byte) but has a smaller weight so you end up paying lower fees.
- P2WPKH addresses start with bc1 as they use bech32 encoding
the only problem you may face when using these address types is when the person wanting to send coins to you doesn't accept this type of address. eg. an exchange that has not yet updated their system after 3 years!
P2SH
is pay to script where the script can be anything. examples are multi-signature scripts, lock time scripts, witness redeem script,...
if you are looking into "nested SegWit" where you have an address starting with 3 but it is using SegWit then the correct term for these scripts are:
P2SH-P2WPKH
they are similar to P2PKH and they require only one signature.
P2SH-P2WSH
they are similar to regular P2SH but with SegWit. they require a "script" called redeem script to unlock.
- all P2SH addresses start with 3 as they use base58 encoding
in both cases the transaction size is moderately larger than their counterparts due to the leftover redeemscript and SegWit overhead but their weight is smaller so you end up paying a lower fee.
the benefit of nested SegWit compared to native SegWit
--------------------------------------------------------------------------------
there is absolutely no difference between these scripts and their SegWit counterparts regarding anonymity or security (at least not on version 0 witness, there will be some additional privacy benefits in future versions with new proposals).
