goshimmer VS metamask-extension

I highly recommend searching for "IOTA 2.0 devnet" - it's a *public* test net running for an year with a new OTV consensus entirely without Coordinator. This is the result of literally years of research (link to research papers: https://www.iota.org/foundation/research-papers ). This is the exact link to the git repo of IOTA 2.0 devnet node software: https://github.com/iotaledger/goshimmer The purpose of Shimmer is to test out these solutions (that already exist) in a real live network - Coordicide will land on Shimmer in a series of modules, which should start happening in the next few months.

Who cares about discord and twitter. He is working even on weekends. https://github.com/iotaledger/goshimmer/commit/3e27a8cb7f128c67244c3d44914b62c078febbd1

That's exactly what the iota foundation is doing, they have built a network where there are no blocks, no commission fees, no miners, the protocol is leaderless, everyone can write on the ledger with their own node. Essentially the network is not competitive (miners trying to mine the block first) but contributory, like bittorrent. Notable fact about congestion, the network exchanges messages that can be only data or economic transactions, the exchange of messages is so fluid that they had to implement a complete congestion protocol in the node with algorithms similar to the TCP layer and a message scheduler. If you're interested in learning more about the technical side, here's a link to their wiki. https://wiki.iota.org/goshimmer/welcome

GOSHIMMER (Coordicide Testnet)

As far as the IOTA ecosystem as whole, we primarily use Rust. Go is being used for prototyping IOTA 2.0 with the GoShimmer node along with some other projects I believe, but Rust is used in the main ones (e.g. client libraries (iota.rs and wallet.rs), Streams, Identity).

[GoShimmer 0.8](https://github.com/iotaledger/goshimmer/releases/tag/v0.8.0) is now out, which means that a working prototype of the final "OnTangleVoting" consensus mechanism is now running on the DevNet.

Have an Ethereum wallet, preferably Metamask installed.

A  Metamask Account.

Plenty of projects are source-available, but not open source, and get tons of issues, and even contributions (https://github.com/MetaMask/metamask-extension off the top of my head)

You can create an attestation based on an existing schema or create your own. Schemas define the format in which attestations will be made, and in this case, we will use the Is Human schema to attest that the owner of a certain address is human. For this example, you only need to connect your Metamask wallet (or any wallet) to Scroll Sepolia, then enter the address you want to attest and click Make attestation. You can choose whether you want the off-chain attestation, i.e., free, obtained only by signing a transaction. Alternatively, you can choose to make it on-chain and pay for the transaction to make it public and connect it to smart contract logic. In this case, you will need to obtain funds in Scroll Sepolia through a Scroll Sepolia Faucet.

Metamask (9000 GitHub Stars) https://github.com/MetaMask/metamask-extension

For this tutorial you will need Metamask or other wallet of your choice, with Scroll Sepolia funds that you can get from a Sepolia faucet and then bridge them to L2 using the Scroll Sepolia bridge. Alternatively, you can use a Scroll Sepolia Faucet to get funds directly on L2.

16) Open Metamask app. In this instruction we will use Metamask extension for Chrome browser.

> I get a 3-5 sec lag on launch [0] as it prepares the browser to block ads.

uBO is typically ready in a fraction of second, so "3-5 sec" is not normal. In Firefox all extensions sit in the same process, so it's possible another extension is preventing uBO to be ready in a timely manner, this has happened[1].
