<h2>About Japan Open Chain</h2><img src="https://res.cloudinary.com/travary/image/upload/w_800/v1/prd-akindo-public/communities/description-images/1PEwowr7nt2l3Q8L.png" /><h2> </h2> Japan Open Chain was designed as an Ethereum-compatible Layer 1 blockchain infrastructure to address challenges such as the speed and rising gas costs of the existing Ethereum mainnet, as well as the legal stability of operators. Its goal is to enable companies and individuals in Japan and around the world to conduct Web3 business with confidence and security. This chain operates as a consortium permissioned blockchain with an open endpoint node model. While maintaining sufficient decentralization, high security performance and stability, it allows trusted Japanese companies to operate in compliance with Japanese law. A key feature of Japan Open Chain is its full compatibility with Ethereum. Tools and smart contracts developed for the Ethereum protocol can be used directly. However, unlike the Proof of Stake consensus algorithm adopted by the Ethereum mainnet, this project uses the Proof of Authority algorithm. The chain's validators are well-known Japanese companies, including Sony Group, NTT Group, Dentsu Group, and universities. <h2>Japan Open Chainについて</h2> Japan Open Chainは、既存のEthereumメインネットの速度やガスコストの高騰、運営者の法的な安定性などを解決することを目的として、日本や世界中の企業や個人がWeb3ビジネスを安心かつ安全に行えるような、Ethereum互換のレイヤー1ブロックチェーンインフラとして設計されました。 このチェーンは、オープンエンドポイント型のコンソーシアム・パーミッションド・ノード方式のブロックチェーンであり、十分な分散性や高いセキュリティ性能・安定性を保ちつつ、信頼できる日本企業が日本法に準拠した運営を行っています。 Japan Open ChainはEthereum完全互換ブロックチェーンであるため、Ethereumプロトコル用に開発されたツールやスマートコントラクトがそのまま利用できることができます。Ethereumとの完全な互換性を有している一方で、コンセンサスアルゴリズムとしてEthereumメインネットで採用されたProof of Stakeではなく、Proof of Authorityを採用しています。チェーンのバリデーターは、有名な日本企業、ソニーグループやNTTグループ電通グループや大学などで構成されています。 Website：<a href="https://www.japanopenchain.org/" rel="noreferrer" target="_blank">https://www.japanopenchain.org/</a>

The consensus utilizes a Directed Acyclic Graph architecture as an intermediary data structure, resulting in a rapid time to finality. In the end, however, Aleph Zero is still a blockchain—not a DAG. The consensus is integrated into Substrate, an open framework built by Parity and the Polkadot developer community. However, this doesn’t make Aleph Zero a parachain but rather an independent Layer 1. In 2024, Aleph Zero introduced <a href="https://zkos.alephzero.org/" rel="noreferrer" target="_blank">zkOS</a>, a software-based privacy layer based on zero-knowledge proofs that serves as a convenient framework that is easy for developers to use. The goal is to make Web3 on-chain privacy infrastructure accessible, user-friendly, and economically advantageous. Additionally, in 2024, Aleph Zero will deploy an EVM-powered Layer 2 upon the Ethereum blockchain to provide even more options for developers wishing to take advantage of the network's unique privacy features.With the above, Aleph Zero aims to solve the shortcomings of DLT base layers and to help the industry tackle the problem known as the Blockchain Trilemma. For more details, please see the <a href="https://docs.alephzero.org/aleph-zero" rel="noreferrer" target="_blank">documentation page</a>.<h2> </h2><h2>Aleph Zeroについて</h2><h2> </h2><a href="https://alephzero.org/" rel="noreferrer" target="_blank">Aleph Zero</a>は、査読付き論文に基づく新しいコンセンサスアルゴリズム <a href="https://docs.alephzero.org/aleph-zero/explore/alephbft-consensus" rel="noreferrer" target="_blank">AlephBFT</a> によるLayer 1 のブロックチェーンプラットフォームです。このアルゴリズムでは、媒介データ構造として有向非循環グラフ（DAG）アーキテクチャが使用されており、迅速なファイナリティを実現しています。しかし、Aleph Zeroは最終的にはブロックチェーンであり、DAGではありません。 このアルゴリズムは、Parity社とPolkadot開発者コミュニティによって構築されたオープンフレームワークであるSubstrateに統合されています。しかし、これはAleph Zeroをパラチェーンではなく、独立したLayer 1 です。 2024年、Aleph Zeroは、ゼロ知識証明に基づくソフトウェアベースのプライバシーレイヤーである<a href="https://zkos.alephzero.org/" rel="noreferrer" target="_blank">zkOS</a>を導入しました。これは、開発者が簡単に利用できる便利なフレームワークとして機能します。Aleph Zeroが目指していることは、Web3のオンチェーンプライバシーインフラストラクチャを、利用しやすく、ユーザーフレンドリーで、経済的に有利なものにすることです。 さらに同年、Aleph Zeroは、イーサリアムブロックチェーン上にEVMを搭載したLayer 2 を展開し、ネットワークのユニークなプライバシー機能を活用したい開発者に対して、さらに多くのオプションを提供します。以上の取り組みにより、Aleph Zeroは、DLTベースレイヤーの欠点を解決し、業界が「ブロックチェーン・トリレンマ」として知られる問題に取り組むことを支援することを目指しています。 詳細については、<a href="https://docs.alephzero.org/aleph-zero" rel="noreferrer" target="_blank">ドキュメントページ</a>をご覧ください。

It is the first cryptocurrency protocol with a succinct blockchain (22KB). Early blockchains, like Bitcoin and Ethereum, accumulate data over time and are currently hundreds of gigabytes in size. As time goes on, their blockchains will continue to increase in size. The entire chain history is required to verify the current consensus state of these networks. With Mina, the blockchain always remains a constant size — about 22KB (the size of a few tweets). It's possible to verify the current consensus state of the protocol using this one recursive, 22KB zero knowledge proof. This means participants can quickly sync and verify the current consensus state of the network. Mina's zero knowledge smart contracts are referred to as zkApps. zkApps provide powerful and unique characteristics such as unlimited off-chain execution, privacy for private data inputs that are never seen by the blockchain, the ability to write smart contracts in TypeScript, and more. <h2>Mina Protocolについて</h2> Minaは、TypeScriptで書かれたスマートコントラクトとゼロ知識証明（ZKP）に基づくレイヤー1ブロックチェーンで、22KBという軽量なブロックチェーンを実現する最初の暗号資産プロトコルです。 BitcoinやEthereumのような初期のブロックチェーンは、時間の経過とともにデータを蓄積し、現在では数百ギガバイトのサイズになっています。時間が経つにつれて、それらのブロックチェーンのサイズは増加し続けます。これらのネットワークの現在のコンセンサス状態を検証するには、チェーン全体の履歴が必要です。 Minaの場合、ブロックチェーンのサイズは常に一定で、約22KB（数ツイート分のサイズ）です。この1つの再帰的な22KBのゼロ知識証明を使って、プロトコルの現在のコンセンサス状態を検証することが可能です。つまり、参加者はネットワークの現在のコンセンサス状態を素早く同期して検証することができます。 Minaのゼロ知識スマートコントラクトはzkAppsと呼ばれています。zkAppsは、無制限のオフチェーン実行、ブロックチェーンから決して見られないプライベートデータ入力のプライバシー、TypeScriptでスマートコントラクトを記述する能力など、強力でユニークな特徴を提供します。

<h2>Introduction</h2>Oasys is a public blockchain specializing in games. It is launching with support from renowned game companies to revolutionize "Blockchain for The Games." Oasys is an EVM-Compatible protocol that adopts the Oasys Architecture. This unique architecture consists of a multi-layered structure: Hub-Layer, a highly scalable Layer 1; and Verse-Layer, a special Layer 2 using Ethereum's Layer 2 scaling solution. <img src="https://res.cloudinary.com/travary/image/upload/w_800/v1/prd-akindo-public/communities/description-images/83LqVlVv2c9pVeJ2.png" /> <h2>From Metaverse to Multiverse</h2> In 2021, the NFT market exploded from the beginning of the year, followed by the rapid growth of blockchain games. The word and concept of Metaverse also went viral after a particular big tech company changed its name in November. Nowadays, millions of people use the term, Metaverse, to describe the Digital World in 3D space, VR, Social Communities and more. This possibly means each company, game, and content creator may have a different view of the digital world; thus, we can expect different Metaverses in numerous forms can be built.From a user’s perspective, we can imagine a future where we go into different Metaverses throughout the day, just like we use social media in our everyday life. This is what we call the Multiverse Era. In this future of multiverses, you can express your identity through avatars, user handles, wearables, or machines you drive, and you’ll be able to use them across all the different Metaverses. This is similar to the worlds you often see in movies and animation. <h2>Leading the World to the Multiverse</h2>There are various issues on interoperability among different Metaverses, which need to be tackled. First and foremost, we need to have a mechanism to guarantee the ownership of digital assets for each Metaverse. The best solution at the moment is to use blockchain and NFT technologies. <h2>How Oasys Contributes to the Multiverse</h2>We believe that blockchain and NFT technologies will play more critical roles in the future of the multiverse. However, the existing Layer 1 blockchain technologies are not sufficiently user-friendly. Extremely slow transactions or high gas fees make the user experience incapable of breaking through to the mainstream and reaching mass adoption. Back in 2018, it wasn’t easy to overcome these challenges. However, by 2021, Layer 2 solutions started becoming available and transactions could be completed at similar speeds as normal servers. As of 2022, most Layer 2 technology solutions are built based on Ethereum, which can transact fast, but at a relatively high gas fee. Therefore, Oasys developed a Layer 1 (Consensus Layer), the EVM public sidechain specialized for games. On the Oasys blockchain, users will rarely use Layer 1 directly because the logic of games will run on Layer 2 (Execution Layer). Game developers can run their own Layer 2 for each Metaverse which will cover all the gas fees for the users. This will allow users to enjoy the Metaverse without worrying about gas fees. Furthermore, we use the environmentally friendly PoS algorithm, which does not require unnecessary power consumption. With Oasys Architecture, game developers can build a Layer 2 Metaverse that is highly usable, flexible, and eco-friendly and as a result, users can enjoy blockchain games with great UX comparable to Web 2 platforms. <h2>Oasys will be the Hub of the Multiverse</h2>The era of the multiverse, Layer 2 technology, the NFT boom, and many other factors have come together at the right time for Oasys. However, these trends alone are not enough to make Oasys a reality; we need the game developers, the gaming community, and most of all, the fans to support us to rebuild the future of gaming.

CROSSVALUE Chain has become Xenea on July 2th. <h2>About Xenea</h2> The Xenea is an EVM-compatible blockchain with integrated sustainable on-chain storage, designed to realize the vision of tokenizing everything and enabling seamless value exchange. Since the data processed on NFTs tends to be large, it is typically stored on external storage rather than directly on a block. However, the persistence of NFT data depends on the storage method. This is also true for existing distributed storage. For example, data on IPFS hosted by a company depends on the length of time that company exists. Also, if the chain is hard forked, consistency of ownership cannot be guaranteed. This causes serious problems, especially for NFT assets. The Xenea addresses these issues by integrating an EVM-compliant blockchain with autonomous decentralized on-chain storage that guarantees data persistence. To ensure that assets can be inherited for a thousand years, the team took a no-compromise approach to the architecture. In developing the core architecture, the team is taking a peer-review approach, ensuring the robustness of the architecture from a computer science perspective through reviews by prestigious international societies, including IEEE.<h2> </h2><h2>Xeneaとは</h2> Xeneaは、あらゆるものをトークン化し、シームレスな価値交換を可能にするというビジョンを実現するために設計された、持続可能なオンチェーンストレージを統合したEVM互換ブロックチェーンです。 NFTで扱うデータは大きくなる傾向があるため、通常はブロックに直接格納するのではなく、外部ストレージに保管します。しかし、NFTのデータの持続性は保管方法に依存します。これは既存の分散型ストレージでも同様です。例えば、企業がホストするIPFS上のデータは、その企業の存続期間に依存します。また、チェーンがハードフォークすると、所有権の一貫性が保証できなくなります。これらは、特にNFT化された資産にとって深刻な問題を引き起こします。 Xeneaは、EVM互換のブロックチェーンと、データの持続性を保証する自律分散型のオンチェーンストレージを組み合わせることで、これらの問題に対処します。1000年先まで資産を継承可能にするため、チームはアーキテクチャに対する妥協を許さないアプローチを採用しています。コアアーキテクチャの開発では、ピアレビューアプローチを採用し、IEEEを含む権威ある国際学会のレビューを通じて、情報科学の観点からアーキテクチャの堅牢性を確保しています。

In April 2024, Japan eased the regulation around limited liability companies, and it is now possible to operate a limited liability company using blockchain technology, including issuing membership tokens in the form of NFT, on-chain voting to manage funds in the treasury, etc Participants must use the Cardano blockchain to develop applications beneficial for DAO operations in general. As of May 8, Yoroi Wallet (non-custodial wallet), NMKR (Token issuance platform), and Clarity (DAO tool) from Cardano have passed negative checks from the DAO Association in Japan and will be the technology assets that can be utilized in this project. You will be asked to consider and develop complementary tools and elements other than the wallet components, such as fungible and non-fundable token issuance, treasury management, and on-chain voting.
