Focal points of the week

Cardano Community takes the Tokyo Blockchain Expo by Storm

On the 26th October to the 28th October, the Tokyo Blockchain Expo once again took place for the second time this year.

An annual event occurring twice a year, the Tokyo Blockchain Expo is a huge gathering featuring some of the biggest projects and organizations in the blockchain space, with a concentration of movers and shakers within the APAC region.

Thanks to our amazing Japanese community and key members such as @yuta_cryptox @leon_stake_pool, @IOHK_miyatake and @BLUSTYURI1 to name a few, the Japanese Cardano community were able to once again plan, set up and run a successful booth at the EXPO, holding regular speaking sessions on a number of topics such as the foundations of the Cardano blockchain in addition to CNFTs, ATALA PRISM and exciting workings to do with a Cardano Metaverse and a partnership with Kittamu, a tourism body that aims to apply Cardano technology to help authenticate local Japan products such as plum-wine.

For more details on the event, you can head to the official site here (Japanese only).

Minimum Pool Cost - Parameter Change

In the last weeks a new CIP draft (Cardano Improvement Proposal) has been discussed heavily among Cardano community members, primarily via Twitter and the Cardano Forum. In essence, it proposes to reduce the minimum pool cost of 340 ada to 0.

The minimum pool cost is a fixed parameter deducted from the overall ada rewards a stake pool receives if it mints one or many blocks during an epoch, more blocks mean more rewards. If no blocks are minted during an epoch, no minimum pool costs are rewarded to the stake pool operator.

The author of the CIP draft, Robin a.k.a ADARobinHood, argues that the minPoolCost makes popularity the basis for pool desirability, causing traits as pledge and performance to mean little in comparison. The core of his argument is that lower saturated stake pools suffer from the minPoolCost as they are unable to attract delegators as their overall ROA % is lower than higher saturated pools. Why is that? Because smaller saturated pools do not mint many blocks per epoch and with a fixed fee of 340 ada on top, a big chunk of the overall rewards are “eaten” by the minPoolCost.

Others argue that the minPoolCost fee is the only reason lower saturated stake pools can continue their operation, especially in lower-income countries. Without the 340 ada per epoch, many stake pools would be unable to cover their operating costs and make a living by running a stake pool.

Additionally, those opposing this CIP claim that by removing the minPoolCost, delegators will only flock to those stake pools with a 0% margin and 0 minPoolCost, as this would mean a higher ROA. This implies that delegators only care about ROA, which can definitely be discussed. To mitigate the risks of a race to the bottom, Sebastien Guillemot and Bastian_from_SHARE among many others propose that in addition to removing the minPoolCost parameter, a new minimum margin parameter should be added.

Among many comments from individual community members, IOG has released a new blog post discussing staking parameters and network optimization. They have presented three potential scenarios regarding changing k and the minimum fee, each with its pros and cons. We highly recommend reading through this blog post and encourage all interested to joining the forum discussion to read through the brilliant takes from various Cardano community members.

Untold Stories with Charlie Shrem and Frederik Gregaard

In mid-October, Charlie Shrem, one of the pioneers in the blockchain industry, Founder and CEO of BitInstand (2011-2013) and a founding member of the Bitcoin Foundation (2012-2014) held a very interesting video interview with Frederik Gregaard, CEO of the Cardano Foundation. In this video interview, titled “Cardano’s Growing Ecosystem,” among other topics such as the Cardano Blockchain, the role of the Cardano Foundation, Crypto adoption and much more were discussed.

Cardano Foundation Metadata Tools Team has developed a decentralized voting application

The Cardano Foundation has been working on a voting app that allows everyone to vote on the Cardano blockchain.

In addition to making sure that this solution works effectively for its initial purpose of voting for the community-chosen speaker and award Summit nominees, the team has also been taking steps toward improving it for future use.

Read more about the Cardano Foundation voting application, called Cardano Ballot, in our recent blog post.

Cardano Foundation Participation at recent events

In the past months we have had quite a bit of community events; from the Token 2049 conference in Singapore to the cNFTcon and WB3X event in Las Vegas, and the RareBloom event in Colorado. These were all great opportunities, not only for projects to showcase what they’re building, but also for community members to finally meet each other in person and connect on a deeper level.

The Cardano Foundation also took part in all three events:

We co-organized the Token 2049 Singapore conference, with the presence of Jeremy Firster.

At cNFTcon both Jeremy Firster and Umar Jan were present on behalf of the Cardano Foundation. Both took time to connect with the community to better understand their needs.

Following the cNFTcon event, the two have moved on to attend the Web3Expo, where Jeremy provided a presentation on Cardano for Enterprise & Supply Chain. To allow several community member to join the event, Cardano Foundation provided free tickets that were raffled via social media.

At the Rare Boom event, Jeremy provided the opening speech. Again both Jeremy and Umar took time to connect with the community and get to know more about their needs.

We are grateful to all organizing parties who helped to put each of these events together.

In the coming weeks, the Cardano Foundation is planning to release a more extensive blog post that will cover all events more in detail.

How the incentive model works?

Cardano pays staking rewards for service for the protocol. Decentralization and security of the protocol is growing along with the distribution of ADA coins. The higher the value of ADA coins, the more expensive a potential 51% attack will be. Demand for coins increases security. The more distributed ADA coins are among users, the more people will decide the fate of the protocol. The protocol must motivate people to hold coins, so it gives them the opportunity to create passive income.

Decentralized networks are like companies that have revenues and expenses. As we described above, the expenses are related to security and decentralization. Furthermore, there are expenses related to protocol maintenance, innovation, and ecosystem development. Revenues are made up of the monetary reserve, i.e., ADA coins that will be released into circulation in the coming years. In addition, fees collected for services. Once the reserve is depleted, the protocol will depend solely on the fees collected.

Services must be created around the Cardano protocol that will be widely used. This is the only way to create a working econonomy that will ensure the long-term sustainability of the key parameters of the protocol. Source

Spotlight for Community-built Tools

The Developer Portal was created to foster a home for developers who are dedicated to building tools and services on Cardano. The platform allows developers to not only collaborate on projects but also to showcase their works.

The Developer Portal aspires to become a credible source where users can search for tools to fit their needs.

Community projects already running on mainnet are encouraged to add their projects to the Developer Portal.

  • RoundTable A open source multi-sig DApp for the cardano blockchain.
  • HAZELnet A community integration tool that allows stakepool operators and NFT projects to connect and engage with their audience, verify their delegators and holders, create polls, whitelists and more via Discord, Website, and other social media apps.
  • Haltscam Haltscam allows and provides a means of crowd-sourcing risky Cardano addresses, allowing community members to contribute to the database and prevent their fellow adopters from falling victim to scams or solicitation.

Is CF in contact with Meta or Twitter?

No, this was a collab with Polygon, I believe. It also includes Instagram.
Facebook now does not allow any NFT website marketing on the platform now. You will receive some kind of Scam posting not allowed message. They are protecting their investment.
