This article mainly explains "what is the method of Bytom information winding". The content of 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 method of Bytom information winding".

Many people who know better than the original chain know that the original chain is a common chain project that focuses on the interaction and flow of information and digital assets on the chain, and the information on the chain is not the core competence of the original chain, so it does not make a functional entrance at the end of the wallet. but the original chain provides relevant interfaces to write some information to the chain. So how to realize the information winding? Using a special Retire operation, this operation can destroy assets, but because it can be accompanied by information, it can be used to link the information.

Please read on, also use postman to request a demonstration, and then write an interface demo in golang. Before implementing it in golang code, we need to do some preparatory work.

First of all, make sure that you have set up the original node locally.

Make sure your account has enough BTM test coins.

Issue one's own assets

The essence of information winding is to create and send a transaction. We all know that there are three main steps to initiate a transaction through api: first, build → sign → submit, and the corresponding api are build-transaction, sign-transaction, and submit-transaction. The request process with postman is as follows:

Request build-transaction API:

Request parameters:

{"base_transaction": null, "actions": [{"account_id": "0KTCS3R5G0A02", "amount": 10000000, "asset_id": "ffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff", "type": "spend_account"}, {"account_id": "0KTCS3R5G0A02", "amount": 100, "asset_id": "608037f96e8d1613d900c67a0730cc90e2a03311fb7d091588f7eb551a6103cd", "type": "spend_account"} {"account_id": "0KTCS3R5G0A02", "amount": 100," asset_id ":" 608037f96e8d1613d900c67a0730cc90e2a03311fb7d091588f7eb551a6103cd "," arbitrary ":" 77656c636f6d65efbc8ce6aca2e8bf8ee69da5e588b0e58e9fe5ad90e4b896e7958c "," type ":" retire "}]," ttl ": 0," time_range ": 1521625823}
