  1. Cool! Very helpful for those who are just starting out!
  2. I enabled EventNotifierConnector.Enabled = true in observer node and observer start to push events like: POST /events/finalized HTTP/1.1 Host: localhost:5000 User-Agent: Go-http-client/1.1 Content-Length: 75 Content-Type: application/json Accept-Encoding: gzip {"hash":"94e75f10d8b598b516a5c84a52a2fa0c404006da94433d5b3abe8379f286e0d5"} Looks great! Now to have full Blockchain events each shard observer will push events like that: {"hash":"x"} {"hash":"y"} {"hash":"z"} My question is how to know if "hash":"x" belongs to shard 0,1 or 2? Do we have shard number encoded in the hash value? Can I extract shard number from "hash":"94e75f10d8b598b516a5c84a52a2fa0c404006da94433d5b3abe8379f286e0d5" ? I'm not sure but I don't think so ... Now to solve my problem I can setup one ./event-notifier instance for each observer node [obs0] -> push to -> 5000 [obs1] -> push to -> 5001 [obs2] -> push to -> 5002 This looks ok, but I prefer to have only one ./event-notifier instance. I wonder if it's possible to push this event in this form: {"hash":"94e75f10d8b598b516a5c84a52a2fa0c404006da94433d5b3abe8379f286e0d5", "shard": 1} Is it viable? I can have a direction, to see how I can adapt my design for my Elrondex library? Long run I need to extract events from Elrond Blockchain, as fast as I can, in order to review, analize and publish these events to smart consumers over websokets (inclusive web browsers) Thanks! I will post here a solution when I have one! https://twitter.com/elrondex https://github.com/elrondex/elrondex
  3. Hi, I managed to publish the first version of Elrondex library in https://hex.pm/ (The package manager for the Erlang ecosystem) https://hex.pm/packages/elrondex {:elrondex, "~> 0.1.0"} This is first version and we plan to add docs and new functionality in next version. We managed to win #3 place in Battle Of Yields Competition, more details here: https://github.com/ElrondNetwork/battleofyields/issues/902 We also plan to make a presentation about Elrondex library on Bucharest |> Elixir |> User Group https://www.meetup.com/Bucharest-Elixir-User-Group/ If you want to know more please checkout https://github.com/elrondex/elrondex repo or follow us on twitter https://twitter.com/elrondex "Stay Hungry Stay Foolish"
  4. Draft version is publish here https://github.com/elrondex/elrondex Contributions are welcome! Thanks!
  5. Hi, I need a confirmation if YubiHSM2 (https://www.yubico.com/us/product/yubihsm-2/) can store private keys for elrond wallet. From specs I see: Elliptic Curve Cryptography (ECC) Curves: secp224r1, secp256r1, secp256k1, secp384r1, secp521r, bp256r1, bp384r1, bp512r1, curve25519 Signing: ECDSA (all except curve25519), EdDSA (curve25519 only) Decryption: ECDH (all except curve25519) Also not sure, but it seems that now https://wallet.elrond.com/ use eddsa25519. Any help is welcome.
  6. Hi I am Elixir developer and I plan to write Elrond cli library to interact with Elrond Blockchain. This library will target IoT projects that can interact with Elrond Blockchain to make payments. For a start I'm just learning architecture, I'm new to crypto, but a lot of experience as a developer. I plan to come up with a series of technical questions. More about Elixir language here: https://elixir-lang.org/ Thanks!
