This article mainly explains "what is the iban in the Ethernet Square". The content of the explanation in the article is simple and clear, and it is easy to learn and understand. Please follow the editor's train of thought to study and learn "what is the iban in the Ethernet Square"?

To put it simply, the iban account in Ethernet Square is a concept introduced by Ethernet Square in order to connect with the traditional banking system. Web3.js provides a method of translation between Ethernet address and iban address.

Iban: international bank account

The concept of iban originates from the traditional banking system, and its full name in English is International Bank Account Number, that is, international bank account. The role of iban is to generate a globally unique account for any account in any bank in the world for interbank transactions. An iban account looks like this:

XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS

Iban addresses can contain up to 34 letters and numbers, where letters are case-insensitive. Include the following information in the iban:

Country code, used to identify the country, following the ISO3166-1 alpha-2 standard

Error identification code, used to verify the address, using the mod-97-10 checksum protocol, that is, the ISO/IEC 7064 2003 standard

The basic bank account, namely BBAN (Basic Bank Account Number), is used to identify banking institutions, outlets and customers' accounts within the institution. The coding scheme of these three parts of information depends on the country code mentioned above.

If you want to start learning the practical development of Ethernet Square DApp right away, two online interactive tutorials are recommended:

Ethernet workshop course, mainly teaching block chain novice introduction to DApp and intelligent contract practical development

ETaifang development, mainly through node.js, express, ipfs and other development of e-commerce platform of the actual combat

Ethernet Square iban: new country Code and BBAN coding Scheme

Etay Fong introduced a new IBAN country code: XE, where E stands for Ethereum,X for illegal currency (non-jurisdictional currencies). At the same time, Etaifang puts forward three coding formats of BBAN: direct, basic and indirect.

The BBAN in the direct coding scheme is 30 letters / numbers, with only one field: account number. For example, if the 00c5496aee77c1ba1f0854206a26dda82a81d6d8 address of Etay Square is converted to the BBAN account of the direct scheme, you will get XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS.

You can use the web3.eth.Iban.fromEthereumAddress () method in web3.js to perform this transformation:

Let myiban = web3.eth.Iban.fromEthereumAddress ('0x00c5496aee77c1ba1f0854206a26dda82a81d6d8') console.log (myiban) / / XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS

The only difference between the basic coding scheme and the direct scheme is that its BBAN length is 31 letters / numbers, so the scheme is not compatible with IBAN.

The BBAN in the indrect encoding scheme is 16 letters / numbers in length and contains three fields:

Asset number, consisting of 3 letters / numbers

Organization number, consisting of 4 letters / numbers

Customer number in the organization, consisting of 9 letters / numbers

For example, an ethernet square iban account with an indrect coding scheme looks like this:

XE81ETHXREGGAVOFYORK

The front XE represents the country code, 81 is the checksum, and the next 16 characters are indrect-encoded BBAN, where:

ETH: in this case, the asset number in the customer's account. Currently, ETH is the only valid asset number

XREG: organization number. XREG represents the basic registered contract of Etay Fong.

GAVOFYORK: the customer number of the organization

Conversion between iban account and Ethernet Square address

As mentioned earlier, using the web3.eth.Iban.fromEthereumAddress () method, you can convert an ethernet address to an iban account of the direct coding scheme. Correspondingly, you can use the web3.eth.Iban.toAddress method to convert an iban account with direct coding scheme back to the address of Etay Fong. For example:

Let myaddr = web3.eth.Iban.toAddress ("XE7338O073KYGTWWZN0F2WZ0R8PX5ZPPZS") console.log (myaddr) / / 0x00c5496aEe77C1bA1f0854206A26DdA82a81D6D8 check the validity of the iban account

The checksum in the iban account is used to help verify whether a given string is a valid iban account. You can use web3.eth.Iban.isValid () in web3.js to perform the verification. For example:

Let isValid = web3.eth.Iban.isValid ("XE81ETHXREGGAVOFYORK") console.log (isValid) / / trueisValid = web3.eth.Iban.isValid ("XE82ETHXREGGAVOFYORK") console.log (isValid) / / false, because the checksum is invalid, thank you for reading. The above is the content of "what is iban in Ethernet Square". After the study of this article, I believe you have a deeper understanding of what iban refers to in Etay Square. The specific use situation still needs to be verified by practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
