API Reference IOTA networks consist of interconnected nodes that have read/write access to the Tangle. You can connect to these nodes to send transactions to them and get transactions from them.

Mam.create(state, message) Create the payload using the state object and message MAM, Masked Authenticated Message, is one of the most remarkable features of IOTA. Let us speculate the world full of small IoT devices, where their small jobs, flow of microscopic data, and nano MAM is focused on messaging, which means publishing up to date data for further use within the IOTA environment, like the upcoming smart contracts. As this data is already published on the immutable IOTA tangle, it could also serve as long-term documentation. I think MAM is the technology for me, but I am not seeing any MAM Java API. I've downloaded and used the mam.client.js , and played around a bit by cloning publishPrivate.js and trying to invoke it from Java using the Nashorn Script Engine*—but I am currently running into ScriptExceptions having to do with the JS arrow function =>.

This issue is with mam.client.js, they have hardcoded the count = 1, which means there is only one leaf per M Fast and efficient PoWaaS (PoW-as-a-service) for your IOTA wallet, MAM-stream or any IOTA usecase requiring fast transaction turnout. Don't overheat your CPU/GPU by doing IOTA PoW locally, instead use our solution to access consistently fast hashing power. Perfect for low-power IoT devices, mobile and desktop solutions. In the API description (here https://github.com/iotaledger/mam.js/blob/chrysalis/docs/modules/mam_client.md#mamfetch) both mamFetch and mamFetchAll api require a client parameter in format iclient or string. both functions do not work if the client is passed as iclient, obtained from a SingleNodeClient (iotanode) function; Mar 04, 2019 · Further we initialize our MAM object with the IOTA provider Mam.init(iota, undefined, 1)and define it to be of lowest security and change it to be public.

It shows that the Merkle Tree needs enough leafs to hold many messages. This issue is with mam.client.js, they have hardcoded the count = 1, which means there is only one leaf per M Fast and efficient PoWaaS (PoW-as-a-service) for your IOTA wallet, MAM-stream or any IOTA usecase requiring fast transaction turnout.

- goodengineer/streams May 23, 2019 · MAM, currently one of IOTA’s best features, aims to become a standard for IoT devices, even though it is still under development. News about a full-featured rewrite of MAM: MAM+ was recently announced by the IOTA Foundation over a recent blog about the current state of its R&D projects. The IOTA distributed ledger works in a similar way to the other blockchains available through the Blockchain Integration Hub in that it offers public immutable records to be created using EVRYTHNG actions and property updates. However, it uses a different kind of 'chain' - the Tangle. Instead of a n Feb 01, 2020 · The full article was originally published by Yehia Tarek on Medium. Read the full article here.
