SHM Coin
The native coin on Shardeum is Shard and has SHM as its ticker symbol. SHM is the foundational monetary unit of Shardeum and serves a wide range of functions. Each SHM is divisible to 18 digits, similar to ETH on the Ethereum network. We will also refer to it as the SHM token, since a tokenized version of the coin is also used by smart contracts and to be consistent with common terminology.

SHM is a utility token with various uses, including staking, governance, reward token, gas token and transaction fee burning. All transaction fees on Shardeum are burned, allowing the network to remove the SHM from the circulating supply to ensure its scarcity by design and support its long-term value. This approach, among others, are integral to Shardeum’s deflationary economic model. You can read more about the SHM coin and tokenomics.

2023 Apr. DoraHacks announces grant funding to Confio


**dorahacks, cryptosat test highly-secure blockchain setups in space**

![image](https://yakihonne.s3.ap-east-1.amazonaws.com/7489688c05bb72112dd82d54fdbf26bb5f03e1de48e97861d8fce294a2f16946/files/1698256570789-YAKIHONNES3.jpg)

trust is a fundamental component of blockchain protocols and their ability to ensure highly secure and privacy-enabled setups that can reduce the presence of intermediaries in transactions. by building a trusted environment that assures security and transactional integrity, parties can transact in a peer-to-peer format and dependably receive accurate output. yet, introducing trusted environments depends on setting up a protocol that doesn’t invite interference by nefarious parties.

to enhance protocol security, decentralization, and scalability, satellite developer and operator cryptosat teamed up with incentive platform and hackathon organizer dorahacks to experiment with trusted setups in space. performed in conjunction with nanoracks europe, which has been offering commercial space services since 2009, the first-of-its-kind experiment aboard the international space station (iss) demonstrated that trusted setups could be generated in space. in this particular case, space’s remoteness assures greater security and decentralization relative to comparable earth-based services.

in this case, the experiment produced a common reference string (csr), powering a zero-knowledge proof responsible for managing user privacy and protecting the dora grant dao’s (decentralized autonomous organization) voting system. the general idea behind a zero-knowledge proof is that one party doesn’t need to share private information with a second party to prove that a specific output is valid. instead, this proof is provided cryptographically.

the trusted setup is the phase that generates the common reference string. a trusted setup is required to arrive at the validation stage, whereby at least two parties set the standards the zero-knowledge proof depends upon to function. without the trusted setup, a malicious user could upload their own csr to a protocol, thereby invalidating a system’s trust.

in addition to securing the dora grant dao’s voting mechanism to thwart any schemes between voting parties and enable user privacy, the experiment also demonstrated how cryptosat’s low-earth-orbit nano-satellites could offer trusted setups to power other protocols and networks.

proving the prowess of space-based computation

founded in 2020, cryptosat endeavors to bring tamper-proof computation services to multiple markets, including blockchains, applications, protocols, and services. cryptosat, which raised $3 million in its seed round in 2022, including from dorahacks, provides a secure cryptographic computation environment in low-earth orbit via satellites the size of a coffee mug. this solution is made feasible by the falling costs of launching and monitoring a satellite amid the emergence of private space contractors like spacex.

the physical isolation afforded by this approach ensures that the company’s orbiting hardware is tamper-proof and protected against intrusions by both state and non-state actors. unlike earth-based hardware, which depends on high-security measures and internet connectivity along with a power source, cryptosat’s satellite-based computation is entirely self-contained. between solar power and open communication relays, the system is more defensible and sustainable by design. any tampering with the system would require physical proximity to the satellite as it orbits.

the newly-published results from the trusted setup experiments follow the successful launch of cryptosat’s crypto2 satellite on january 3rd aboard the spacex transporter 6 mission. the now-orbiting satellite features 30 times more computation power than its orbiting predecessor, crypto1, which was launched back in may. together, these satellites are helping the company work towards its goal of acting as a trusted execution environment (tee) for  crypto projects and a service provider for other computation tasks that require a trusted setup.

this latest round of experimentation follows other tests carried out aboard the international space station, including drand protocol’s publicly verifiable randomness beacon last year and data security applications. although the trusted setup accomplished during the latest testing on the space station was a success, the scope of its abilities is limited to one setup per application, meaning that there isn’t a general template that can be used across multiple, more general applications.

now, with the first successful experiment concluded, cryptosat and dorahacks can move forward with additional testing and experimentation to refine the trusted computational techniques for more expanded use. the prospective uses include launching new blockchains or adding functionality to protocols through the trusted setup process in space.

2023 Jan. DoraHacks, Cryptosat Test Highly-Secure Blockchain Setups in Space


**dorahacks and cryptosat run the first cryptographic trusted-setup for zero-knowledge in space**

singapore and palo alto, ca / accesswire / january 12, 2023.

 dorahacks, a leading global hackathon organizer and open source incentive platform, and cryptosat, which develops and launches crypto-satellites into space to enable novel cryptographic applications, announced today that they have successfully performed the first experiment to initiate a zero-knowledge (zk) proof system in space.

["this article is part of yakihonne exploretoearn. click to earn more sats!"]
(https://www.yakihonne.com/article/naddr1qq2457f4wvk4vhm4vdskv3jpdf5xkaz3feh8sq3qyzvxlwp7wawed5vgefwfmugvumtp8c8t0etk3g8sky4n0ndvyxesxpqqqp65wqfg09z)

this historic event took place on the international space station (iss), an isolated platform in low earth orbit where no human (except the seven astronauts currently aboard the station) and no hacker can physically access or modify the hardware running the experiment.

the experiment involved taking a set of pre-uploaded open source programs to the international space station, and outputting a file that contains the "common reference string." the common reference string is used in dorahacks' zero-knowledge proof powered voting program that protects user privacy and offers collusion resistance in voting and governance.

the output of this experiment will be used to ensure security of the voting mechanism used in dora grant dao, an open-community grant organization that supports multi-chain web3 infrastructures and public goods. this paves the way for cryptosat towards a satellite-based service that would enable a fast turnaround for initiation of zk proof systems.

"we are excited to unlock the possibility of running trusted setups for zero-knowledge schemes in space. the ability to perform a trusted setup in a completely isolated environment is key in making efficient snark schemes much more widely used, secure and easier to iterate on. by having cryptosat participate in the ceremony, we guarantee there is at least one party out of this world making the ceremony more secure," said cryptosat co-founder yonatan winetraub.

zero-knowledge proof systems, and snarks in particular, enable a vast range of possibilities, from rollups to collusion-resistant voting in daos. so far, the cryptographic ceremonies such as the "powers of tau" required to bootstrap a proof-system had either trust issues, or required bringing large numbers of participants which resulted in complex coordination with long turnaround times for commencing the ceremony.

cryptosat's trusted compute environments in space provide the ultimate physical isolation and security, and will enable it to carry out instant cryptographic trusted-setups for ever-changing software. this experiment is a proof-of-concept that initiates cryptographic primitives in a space orbit, enabling dorahacks to use the output common reference string in zero-knowledge proof powered applications.

it's not without limitations, though. in its current state, the cryptographic scheme (called "groth16") used in this experiment requires a new setup every time the voting program changes, so it works for only one application instead of general applications. moreover, there are two steps of the trusted setup process, and this experiment only runs the second step. its success opens up the gate for dorahacks and cryptosat to design further space missions to improve the process.

"ultimately, we want to use an isolated computing environment in space to conduct a complete trusted setup for zero-knowledge proof applications, including an ‘in-space ceremony' that produces crs for multiple proof systems, like plonk. if we can achieve this goal, we can provide a public good for all zero-knowledge proof powered applications, as well as a new paradigm to initiate cryptographic protocols in general," said eric zhang, the founder & ceo of dorahacks.

the experiment was performed in collaboration with the italy-based nanoracks europe exploiting the ice cubes service in orbit.

2018 Oct. DoraHacks Global Hacker Holds its First Ever Blockchain Hackathon in India


Nostr is a decentralised communications protocol that allows people to transfer and share information without relying on large central servers but broadcasting to a series of relays that anyone can spin up. It is censorship-resistant and private, making it a valuable tool for anyone looking to take control of their data, those living in countries with oppressive regimes, or those who want to protect their privacy and guard against censorship.

Nostr is a generalised protocol that can transfer different events, but it started as a method of hosting short-form posts that clients could read and then render into feeds and create a Twitter-like clone. Today, its user base still focuses on this use case as the core, but we are seeing the protocol expand into new fields like long-form content, live streams, shopping, classifieds, and much more.

To use Nostr, all you need is to generate a set of private keys representing your account, and you can use those keys to access any Nostr client. This set of keys represents your identity, your account and any associated data such as your follower count, notes you’ve posted, zaps and more.

Moving value across nostr
Nostr’s combination of clients, relays and users forms the basis of the network, but the network would only grow with value exchange. Remember, this is not some social media website subsidised by big tech or a massive ad-serving platform.

Instead, nostr monetises through Bitcoin, with users paying one another directly for content in the form of zaps, paying relays to host their content, and even paying clients to encourage them to add new features.

Today, the nostr ecosystem relies heavily on Bitcoin and the Lightning network, with nostr accounts tying their npubs (public key) with a specific Lightning address as the method of payment. When a nostr user wants to pay another, they have to enable a Lightning wallet and associate it with their account. This could be a non-custodial Lightning wallet, but most opt for custodial wallets.

Another option that has started to see adoption among nostr account holders is the Cashu wallet; this uses a nostr public key as a wallet address by tying a nostr account to an eCash mint. eCash tokens can be sent directly to users and is also interoperable with the Lightning Network so that users can send and receive funds as Lightning payments or eCash payments.

While these two payment methods are users’ primary options today, others are available, such as Nostr Asset Protocol, which aims to offer a different solution that appeals to those outside the Bitcoin ecosystem.

What is the Nostr Asset Protocol?
Nostr Assets Protocol is a new open-source protocol focusing on bringing Taproot assets and native Bitcoin payments into the Nostr ecosystem. It uses your nostr account as a wallet, with your npub becoming a static wallet address, while your private key now has rights over content events and monetary events.

This smoothes out wallet creation and makes interacting with different nostr users seamless regarding payments and online commerce, like trading or eCommerce. Instead of requiring a separate Bitcoin wallet, your nostr account could be used to pay users online or in person as long as they have a nostr account.

The Nostr asset protocol allows you to interact with other payment protocols, like the Lightning Network and Taproot assets. Once the assets are introduced, users can send and receive them at the Nostr Protocol layer using Nostr’s public and private keys.

The settlement and security of assets still rely on the Lightning Network, and the Nostr Assets Protocol itself does not issue assets but only introduces assets into Nostr through the protocol, allowing you to trade a claim that can be redeemed on the Lightning network.

What is Nostr Assets Daemon (NAD)?
The Nostr Assets Daemon (NAD) is a backend process that implements the Nostr Assets Protocol for issuing assets on the Nostr Protocol.

It serves as a wrapper for Taproot Assets (formerly known as Taro) and Lightning Network, allowing users to effectively manage their assets on Bitcoin (BTC), the Lightning Network, and Taproot using their Nostr accounts.

While this is the core focus for now, the Nostr Assets Daemon could be used to incorporate assets hosted on other protocols, too, like RGB or the Liquid network. What does the Nostr Asset Protocol do?
Bridge Taproot assets or Lightning balances to trade them via Nostr events
Mint Nostr Assets
Send and receive Nostr Assets
Provide separate accounts for end users
Compatible on both Self-Custodial and Custodial users
Redeem your nostr assets for funds on your preferred network
Chat-To-Trade
Users can transfer, receive and query Nostr assets using chat commands directly through any Nostr Protocol frontend clients such as Damus, Amethyst on mobile or Iris, Primal and Snort on Desktop.

Zero-gas transactions
Since the Nostr asset protocol does not use a blockchain and does not transfer funds that require interaction with the chain, it costs no fees, as you’re creating another nostr event like you would when making a post. As Nostr Protocol is an off-chain decentralised protocol, all transactions can be encrypted and gas-less to operate.

Besides deposit and withdrawal functions, all transactions on Nostr Assets Protocol are Zero-Gas transaction fees; users can save on fees and redeem to their Lightning Network or on-chain wallet when ready.

Trade using your preferred asset
Since the Nostr Asset Protocol can support any asset bridged into it, if Taproot Assets shows support for Stabelcoins like Tether USDT, users would be able to bring those assets into nostr and use them to pay other users, tip them in a native currency of their choice or conduct sales and even P2P trades using the protocol.

 This opens up Nostr to users who might not be interested in Bitcoin but still want to take advantage of the network’s other benefits.

Run your own Nostr Assets Node.
Nostr Assets Protocol enables users to set up and run their own Nostr Assets Node for self-custodial management of Nostr assets, so you don’t have to trust someone else data on these assets.

Nostr Assets are still in their early stages of development. Still, they can change the value proposition ecosystem by appealing to users who want to use a different unit of account. By combining the censorship resistance of Nostr with the scalability and security of the Lightning Network, Nostr Assets offers a new way to conduct online trade.

Nostr prepares for the digital and attention economy migration.
Appealing to a broader community requires the support of assets others want to trade in. Despite Bitcoin’s growth, the total addressable market for fiat settlement every day is orders of magnitude larger. The lack of native assets or currency in the Nostr ecosystem has hindered effective commercialisation and limited venture capital investment.

If, for example, traditional social media users begin to realise they can migrate their content and user base to nostr and collect a more significant revenue share than if they used other online platforms like Patreon or payment providers like PayPal, they might be more likely to move over.

By bridging existing networks into nostr, you allow the market to decide how they want to interact with one another as nostr assets would be platform and asset agnostic.


After the Nostr hype begin this year I was not very active on the network this summer like many others (the same applies to Mastodon). Still, a nice group of power users is still very active and developers are still building clients and improving NIPs. This holds my believe in Nostr strong.

For those who are new to Nostr, here is a short explainer what it is.

Nostr is a communication protocol and an acronym which stands for Notes and Other Stuff Transmitted by Relays. It is an open, independent standard upon anyone can build. Nostr is designed for simplicity and enables censorship-resistant, decentralized and global publishing on the web. All data is sent in events packaged as plain JSON which are shared between applications and relays.

For me, Nostr resonates with many trends and signals I follow on the internet. Plus, it matches many of my own personal values around online privacy and digital autonomy. Nostr can fix the web in a similar way how bitcoin can fix the money system. And try to image when the two merge together.

For me it makes sense that Nostr will evolve into a future-proof protocol. I will try to clarify that in my article below.

Nostr clients are local-first
In the last decade our devices have transferred to very powerful small computers, like your smartphone. This means applications can do a lot of smart stuff without the need of someone else’s computer, the so called cloud with a huge backend of programs and services. Thanks to Nostr we can fade away from the classic “many-clients-to-one-server” ecosystem used by the tech monopolies for their benefits.

Data portability between clients
Have a look at the long-form content with Nostr (kind 30023 from NIP-23) so called blog content. These two websites are the most popular which integrated NIP-23: blogstack.io and habla.news. Let’s compare a piece of content to see what data portability means:

You really own your identity
Anyone can create keys which represents an identity. You have to save and secure your secret key which is used for signing your events with content. Please be aware: with this ownership of your signing-keys comes responsibility for your identity and data.

Privacy by default
The signing of events are done with the same public-key cryptography as you can find in bitcoin for signing transactions. Like Bitcoin, Nostr is not anonymous. Your identity is a pseudonym. You have full control of what you share with this pseudonym. If you desire full anonymity, you have to use clients which use the Tor network for example. Or use the Tor network on your behalf while using Nostr clients.

Permissionless
Like with many other protocols you are free to start building. Just build a client, connect with some relays and start requesting notes (kind 1) for example for making a feed with the latest posted notes.

Going trustless
You can use the Nostr network with a lot less trust than other services, especially compared to the BigTech in the social media ecosystem. The Nostr protocol is not owned by any third party or authority, just like the http protocol for websites or smtp protocol for email. It’s open and independent by default. The trustless way is to build and run your own client, create your keys on your behalf and run your own relay. Than others clients can connect to your relay to see the events you’re broadcasting.

It’s easy and developer friendly
Any junior developer could set up a client within a couple of hours. There are plenty of simple projects written in different languages on Github you can use as a starting pint. At this time of writing, there are more than 700 public repositories tagged with Nostr on Github.

Censorship resistance
Nostr is a perfect match for building freedom technology, because the open and independent character of the protocol. Each client can connect to multiple relays to broadcast events. When a relay decides to block you, you can easily use other relays to send your content to others.

Nostr is agnostic and for any data you would like to share
The protocol can be used for any data you would like to transfer. Have a look at this list of different types of content called kinds (there are many more, this is just a selection):

Kind	Description
0	Metadata
1	Short note
4	Direct message
6	Repost
7	Reaction
1984	Report
9735	Zap
30023	Long-form content
30078	Application specific data
The majority of content are notes with kind 1 which are immutable. Long form content (kind 30023) is not immutable, it’s editable. Another example is kind 7 which is used for comments (or kind 1) or other types of reactions on content.

Integrating the value4value model
Zaps are so cool! Let’s pay with sats instead of our personal data and attention. The value4value philosophy is really a game-changer on monetizing content. Nostr has adopted this model (just like Podcasting 2.0) and is demonstrating how real digital value (backed by bitcoin sats) works. You have to option to enable zaps so you can send and receive sats on content you share.

Backed by a community
Nostr is being bootstrapped by the bitcoin community. There is a huge advantage of early bitcoiners who have less financial worries so they can back the Nostr community. There are funds available for many type of projects for attracting more people into the Nostr ecosystem.

It’s still very, very early
Compared to a new discovered territory, we’ve just started building small shelters. The Nostrverse is still very small with maybe 100 builders who are tinkering their way around the protocol. This means new clients and features popup every week. As now, many clients (and relays) are suffering from different performance issues. Most applications out there are doing one thing incredibly well. This means you need to use many different applications to understand and feel the Nostr experience. That’s currently how I’m moving through the Nostrverse. For now that’s ok. We need that friction to innovate and drive discovery. There is no freedom without restrictions. I’m sure the future will bring many more great applications with features which will show a completely new paradigm on how the web can work for us: the individuals.

Social media plays a crucial role in the cultural, political, social, and economic aspects of our digitally-connected lives. Controversies like the Facebook–Cambridge Analytica data scandal – where personal data was used for political advertising – and censorship tactics used on popular sites like Twitter have forced users to look for better alternatives.

To bridge this gap, several decentralized social media platforms have emerged. These aim to empower users by granting them control over their data, removing advertisements, and banning social media addiction-inducing algorithms. Out of the lot, a protocol called Nostr has stood out, amassing thousands of users.

Is Nostr the answer to social network concerns? What about other alternative decentralized social media platforms like Bluesky and Mastodon?

In this article, we try to answer these questions.

What is Nostr?
Nostr (Notes and Other Stuff, Transmitted by Relays) is an open protocol on top of which developers can create censorship-resistant social media applications. The Nostr Manifesto was first published in November 2019 by its pseudonymous creator Fiatjaf.

Remember that Nostr is not a social media platform like Twitter, Instagram, and Facebook. It provides the infrastructure needed to create a decentralized social media network.

Iris, Damus, Nos, Amethyst, and Gossip are among the many social media applications built on Nostr. These are also called clients.

How does Nostr work?
Relays are the critical components in the Nostr protocol. They are backend servers that allow various social media platforms to send messages to one another. Relays can store user posts and messages, enabling seamless interaction across platforms.

Users can connect to multiple relays to save their account details, posts, and social interactions. Connecting to several relays ensures that a user always has access to their data in case a relay goes offline or gets censored. Nostr also allows users to run their own private relay to remove doubts about becoming censorable. At the time of writing, 218 Nostr relays were online.

Each user account on Nostr has a public-private key pair. You can think about public keys as usernames with which you can search for your friend’s Nostr profile. Your private key is your password.

Users can jump between various decentralized social applications built on Nostr using their public-private keys. If you get kicked out of platform ABC, then you can move all your posts, messages, and followers to another platform XYZ and carry out business as usual.

Although there are a lot of similarities between the Nostr protocol and blockchain protocols, Nostr is not a blockchain. It is simply a set of rules. Nostr, however, does draw inspiration from blockchain protocols like Bitcoin in championing decentralization and interoperability.

Just like the Bitcoin network, Nostr is not owned by any corporation. Changes to the protocol are pitched, discussed, and approved by the community in the form of Nostr Implementation Possibilities (NIPs) on GitHub.

According to Greg Heartsfield, “Nostr tries to solve the problem of publishing short notes (“and other stuff”) on the Internet.”

“Twitter solved this problem neatly, then complicated it through API and client restrictions, advertising, and a clumsy interface. Finally, they fully unsolved it by inserting themselves as the arbiters of what speech is allowed.”

Why is decentralized social media needed?
The loss of trust in centralized platforms like Twitter and the increasing degree of censorship practised on social media platforms has prompted developers like Fiatjaf to create decentralized social media protocols. In the Nostr Manifesto, Fiatjaf noted several problems with Twitter, namely ads, algorithms, banning and shadow-banning users, and spamming.

Nostr has seen an influx of new users since 2022. This came during a turbulent time for Twitter which saw Elon Musk buy the microblogging platform for $44 billion. During Musk’s Twitter reign, the company has made a slew of changes that sparked the ire of some users. It implemented anti-free speech moves like censoring links to external websites, discontinuing free access to the Twitter Application Programming Interface (API), and suspending the Twitter accounts of prominent journalists.

As the masses flocked to decentralized social platforms on Nostr, the total number of users on the protocol – measured by “profiles with bio and contact list” – skyrocketed from about 800 on 7 December 2022 to over 315,000 by the first week of June 2023.

Endorsements from Twitter co-founder and Block CEO Jack Dorsey have also helped increase Nostr’s reach and visibility. Dorsey not only tweets about Nostr on a frequent basis, but he has also donated 14 BTC – worth over $381,000 at the time of writing – to Nostr creator Fiatjaf.
Other famous names like Edward Snowden have also voiced their support for Nostr. The crypto community, in particular, has shown an affinity for Nostr, given similar principles of decentralization that the two communities uphold.

Furthermore, recent improvements on Nostr, allowing users to send BTC to each other via the Lightning Network, have attracted Bitcoiners to the protocol.

Embracing Decentralization: Is Nostr the Answer to Social Network Concerns?
