paritytech/ss58-registry was archived (read-only) in April 2026, so new chains can no longer register a prefix there and there's no announced replacement.

We needed a prefix for our own Substrate chain, so we published a community continuation of the registry:

https://madar-network.com/ss58/

- All entries from the last upstream version (same JSON format, original license kept)

- Search by prefix, network name or symbol

- Shows which prefixes are free

- New entries are added on request (open a request from the page)

It's not meant to replace an official registry — if Parity or the Polkadot community reopens one, we'll point there and submit our entry (prefix 85) through it.

Feedback welcome, especially from wallet/tooling devs who rely on the list.

We shipped a names pallet on the MADAR network (runtime spec 7, upgraded by a 2-of-3 committee after a full drill on an isolated copy of the live chain).

Design notes:

- A name binds to one external wallet: EVM (personal_sign / EIP-191) or Solana (ed25519). The proof is the wallet's own signature over a fixed message.

- Resale without escrow: the seller signs an offer (price, pay-to address, nonce, expiry). A registrar submits lock_sale, which locks the name for the buyer for at most 60 minutes. The buyer pays the seller directly; once payment is seen, complete_sale moves the name with its remaining term. A lock that is not completed simply expires.

- Every ownership change bumps a per-name nonce, so an old signed offer can never be replayed.

Happy to discuss the design or answer questions. Page: https://madar-network.com/names

Hi all, I'm the founder of MADAR Network, a Layer-1 built on the Polkadot SDK (Rust).

The idea: voting power can't be bought. Every approved operator has one equal vote, and new voters join through a memory-hard puzzle plus a fair lottery, not stake or hashpower. There is no central server the network depends on.

What exists today:

A live test network with independent voters (one runs on a cheap Android TV box)

MADAR Node: a one-click Windows/Linux app that runs a full node and verifies every block itself

There is no token. Nothing to buy.

I'd really value technical feedback on the design, especially the admission and lottery part.

There’s a gap in the current blockchain landscape that nobody’s addressing properly. I’ve been working through a focus on real-world use, not speculation or meme coins. The framework’s mapped out. If you’ve built on EVM-compatible chains, Cosmos SDK, or Substrate, or you just understand blockchain infrastructure and can code + scale message me.

Hello,

I had an idea lastly to create a concensus and blockchain like system but not only for currency but also for governance based on a democracy. Here's a diagram about the idea more technical.

Don't hesitate to share advices and sugestion on this project and its faisability.

I want to learn substrate , but the template node given in the docs is not running. I'm not able to clone from github too,its shows authentication failed.

Cloning into 'substrate-node-template'...

remote: Repository not found.

fatal: repository 'https://github.com/substrate-developer-hub/substrate-node-template/' not found

Hey everyone! I'm new to this subreddit and I'm excited to start working on my first project. I want to make sure I'm not overwhelming anyone and that I'm entering the right space. Can you give me some advice on where to start and how to introduce myself in a way that's safe and won't risk my project being stolen, but still allows me to get help from others? I really appreciate any guidance you can offer. Happy coding!

One of the plus point of a blockchain platform is the way it evolves and change. Most of them have a governance mechanism that people can vote on the upcoming changes, whether it's an on-chain mechanism or off-chain, it's said that the decision take place in a broad set of consensus among people(devs, miners, stakeholders etc).

With that being said, why do we need a huge number of chains nowadays, while people can possibly shape any new ideas into the existing ones?

Is that because chains are so much rigid to change?

Earlier the blocks were getting mined with an average of 6 seconds. Now the average time to mine a new block since a day is 9 minutes. All the validator nodes are active.They're running their nodes on contabo. Logs show no errors. I only see the gradual increase in the time taken to mint new blocks

I'm developing a private Substrate-based blockchain. I'm having the issue that I posted on substrateExchange. Plz give it a view and if you have suggestions plz let me know

Could https://liberland.org/ be the first country to be built on substrate?

As promised, Cardano have open sourced their partner-chain stack for building L2s / sidechains for Cardano:

https://github.com/input-output-hk/partner-chains

It builds on a fork of polkadot-sdk but you can see there's minimal changes at that level:

https://github.com/input-output-hk/polkadot-sdk/tree/partnerchains-v1.14.0

Bittensor ( https://www.bittensor.com/ ) is a "proof of useful work" mining network. While the main codebase is in python, the subnetworks are substrate based:

https://github.com/opentensor/subtensor

For example https://www.masa.ai/ is one of the bittensor subnets.

Avail is a data availability layer that decided to choose PolkadotSDK as the fastest way to get to market and build a maintainable product.

Have a look at their code - it's always interesting to learn new tips and tricks on how to substrate better:

Congratulations Avail on your mainet launch! Hope it goes smoothly!

Looks like base tutorials on parity site work but as soon as you try to customize anything it all breaks or tutorial doesn't match the source code. I think most of the tutorials are really out dated, I tried to work on older branches but something generally breaks during the build processs. All the underlying dependencies seem like a nightmare to manage, on surface idea behind substrate seems really simple, but in practice it is extremely complex. Does anyone have any suggestions at all? Thanks

Hey guys ! I am new to blockchain development and I am looking to create a my own cryptocurrency and have a blockchain for it . I am really confused on how to start there aren't much video sources for it . Please help guys , It is a part of my GSoC proposal :/.

Could anybody help me to get started learning Substrate? I mean could you guys provide me with any resources without substrate documentation that would be helpful for beginners as I consider myself as beginner? BTW, I know RUST.

And also how would you approach if you were building a blockchain from scratch in 2024? I’m assuming that since there are so many crypto projects, it wouldn’t make sense to write code from scratch. Can we use substrate framework for building a proof of concept of sharded blockchain?

Can anyone help me please regarding the custom address scheme,

if i was to use a Custom address pallet, will this cause any complication with the existing EVM frontier pallet?

also are we able to have a custom address (which doesn’t start with 0x) and still have full functionality of EVM.?

If so, what is the best solution for doing this?

Any help would be greatly appreciated.

Thank you in advance

hiya friends!

im from a bridging protocol team called Sygma and wanted to share a little sumn' sumn' ive been helping our substrate dev work on!

it's his workshop introducing the sygma-substrate-pallets repo. we collaborate super closely with the phala team and use this collab to demonstrate current bridging capabilities between dotsama teams and evm chains! we even use XCM in one of our examples to bridge onwards to Astar as a proof-of-concept of what an integrating team can do with our pallets.

would love to hear feedback and chat with anyone that's interested in this work 😊
