Dalam langkah yang menandakan perpaduan antara penyimpanan terdesentralisasi dan infrastruktur kecerdasan buatan mutakhir, Yotta Labs telah mengumumkan pengadopsian Protokol Walrus untuk memfasilitasi penyimpanan bagi beban kerja AI terdesentralisasi berskala besar. Kolaborasi ini menyoroti meningkatnya permintaan akan solusi penyimpanan yang aman, skalabel, dan efisien, yang mampu mendukung generasi berikutnya aplikasi AI.
Mengapa Protokol Walrus?
Beban kerja AI, terutama yang bersifat terdesentralisasi atau terdistribusi, menghasilkan jumlah data yang sangat besar yang harus disimpan, diakses, dan diperbarui secara andal. Solusi penyimpanan awan tradisional, meskipun cepat, sering kali mahal, terpusat, dan rentan terhadap gangguan, yang dapat menghambat kinerja dan memperlambat pelatihan model AI.

Penyimpanan terdesentralisasi sedang merevolusi cara data disimpan dan dibagikan di Web3. Namun di balik permukaan dari setiap jaringan penyimpanan ada pertanyaan krusial: apa yang sebenarnya disimpan oleh node? Di Walrus Protocol, di sinilah keajaiban kode erasure RedStuff muncul.
Blok Pembangun Penyimpanan
Berbeda dengan sistem penyimpanan tradisional di mana node mungkin menyimpan salinan lengkap dari file, Walrus menggunakan sliver—fragmen kecil yang telah dienkripsi dari dataset yang lebih besar.
Sliver adalah fragmen tunggal yang berasal dari salah satu:
kode baris, atau

The Core Problem RedStuff Solves
Any decentralized storage system must solve three competing goals:
High availability (data always retrievable)
Low redundancy (storage isn’t insanely expensive)
Byzantine tolerance (nodes can be malicious, not just offline)
Most systems sacrifice one:
IPFS → cheap, but no guarantees
Filecoin → guarantees, but huge replication overhead
Arweave → permanent, but inefficient and archival
RedStuff solves all three simultaneously.
Why Simple Erasure Coding Is Not Enough
Classic erasure coding (Reed–Solomon)
Split file into k chunks
Add n−k parity chunks
Any k of n can reconstruct the file
Problem:
Assumes honest but failing nodes
Breaks under Byzantine behavior
Walrus assumes malicious nodes, not just crashes.
Two-Dimensional Erasure Coding
Instead of a 1D stripe, RedStuff encodes data in a 2D matrix.
Step 1: Blob → Matrix
Suppose a blob is split into a matrix:
D11 D12 D13
D21 D22 D23
D31 D32 D33
Each Dij is a data block.
Step 2: Encode Rows and Columns
RedStuff applies erasure coding twice:
Row encoding
Each row gets parity blocks:
Row 1: D11 D12 D13 | R1
Row 2: D21 D22 D23 | R2
Row 3: D31 D32 D33 | R3
Column encoding
Each column gets parity blocks:
Col 1: D11 D21 D31 | C1
Col 2: D12 D22 D32 | C2
Col 3: D13 D23 D33 | C3
Now every data block is protected horizontally and vertically.
This is the 2D redundancy.
Why This Is Byzantine-Resilient
Let’s analyze failure modes.
Case A: Nodes go offline
Row codes recover missing blocks
Column codes recover missing blocks
Case B: Nodes lie (Byzantine)
Invalid slivers are detected via:
cryptographic commitments
consistency checks across dimensions
Case C: Adversarial delay
Nodes cannot wait to see challenges
Proofs are asynchronous
Delays = penalties
A node must continuously store data, not fake it later.
Mathematical Guarantees
Let:
f = fraction of Byzantine nodes
n = total nodes
k = data threshold
RedStuff guarantees:
Data availability if < 1/3 of slivers are Byzantine
Recovery bandwidth proportional to lost data only
Reconstruction probability → 1 as matrix grows
This is far stronger than 1D erasure coding.

Apa yang Sebenarnya Ditargetkan oleh MiCA (Konteks Penting)
MiCA (Regulasi Pasar Aset Kripto) tidak mengatur blockchain secara langsung.
Ini mengatur:
Penyedia Layanan Aset Kripto (CASPs)
(pertukaran, penyimpanan, makelar, penerbit)
Aset kripto yang ditawarkan kepada publik
Integritas pasar, pengungkapan, dan perlindungan konsumen
Perbedaan ini sangat penting:
MiCA tidak melarang teknologi privasi — ia mengatur bagaimana teknologi tersebut digunakan.
Ketakutan Besar MiCA: 'Koin Privasi Dilarang'
Ini adalah salah paham.
MiCA tidak secara eksplisit melarang koin privasi, tetapi mengharuskan CASPs untuk:

Dusk Network presents Citadel, a zero-knowledge proof KYC solution where users and institutions are in control of sharing permissions and personal information. The framework can be used for all claim-based KYC requests and puts users in total control of what information they are sharing and with whom while being completely compliant and private at the same time.
How does it work
Dusk Network is the first to integrate zero-knowledge technology KYC in a Layer-1 (L1) blockchain. It is a key feature of Dusk itself to implement it in its privacy-preserving protocol. Using the Citadel framework, an entity that is able to handle private information - for example, the company Dusk who is compliant with all necessary regulations and is allowed to handle private information, or a company that is verified to do KYC on behalf of institutions - can provide a list of requirements for their KYC verification. The user who needs to complete the KYC is able to provide the necessary information, share how long their information can be stored and can withdraw access to their data. The company will authenticate the data, which will be privately stored in the Dusk blockchain. To simplify: it is using non-fungible token (NFT) technology, where instead of an art piece, a license is created.

Use case

If you open a bank account, you need to KYC and share personal information with your bank. If you then decide to do stock trading, you'll need to open an account with a brokerage service, where you will alsohave to do KYC/Anti-Money Laundering (AML). You will either have to share the same information with them or your bank will provide it to them. If you buy a house and get a mortgage, you will also have to offer a lot of KYC/AML/personal information. All these players will keep your information and store it, which both has a big impact on your privacy and puts you at risk of data leakage. Instead, if you use Citadel, you would store your data with one party who is only able to store and verify data, and other services can opt to accept the licenses and use that as KYC/AML proof.
This significantly reduces risk and privacy exposure. In a fully on-chain world, you can buy regulated assets simply by providing a license that you're in compliance with the requirements of the trading platform. You can borrow money from a lending service by providing a license that meets their KYC and AML requirements. You can loan out money and get yield, simply by providing the license. No need to share personal information with the three parties. For safety measures, a quarterly confirmation of the correctness of all the provided data in the license could help data stay up to date.
Cost-reducing compliance
Banks and financial institutions are often complaining that new regulations like the Travel Rule and other Anti-Money Laundering measures are costly operations, costs that are also charged to the customer. The processes to meet the requirements are tedious, time-consuming, and involve many unnecessary parties, making the process even more challenging. Citadel as an SSI protocol can provide the basis for a KYC service that could eliminate the need for financial institutions to do KYC/AML themselves and/or with third parties. It can significantly reduce the cost of gathering, protecting, and renewing client information. A KYC provider built on Citadel will speed up processes and information is always up to date, real-time accessible, and privacy-preserving. With Citadel, the client will be fully in charge of their own details, without unnecessary information duplication and a reduced risk of information leakage.
Next to digital identity verification like in the use case above, Citadel can be used for privacy-preserving transactions and global compliance.
Additional uses
This is just one way that Citadel can be used. Citadel offers much more than can be described in a single article, so expect more information and use cases in the future.
Citadel offers access to services without having to share personal data or information. This is practical, efficient, and preserves privacy for users. We’re so used to having to share and expose our personal data to gain access to services that it’s hard to imagine not needing to do this.
It has benefits for companies and provides relief from GDPR which is currently a heavy burden for companies to bear. By allowing users to access services and membership etc without sharing their identity or data, there is nothing that needs to be “forgotten” to comply with GDPR. This will be a huge relief for companies operating in the EU.
It offers protection from hacks and data leakages. From LastPass to Celsius to the countless hacks and leaks you won’t have heard of, companies simply won’t have this data so there’s nothing to hack. This is good for institutions as it makes them more secure and is good for users who don’t have to trust a 3rd party to look after their most important data.
Citadel changes the relationship between users and providers and eliminates the need to swap your identity for access, and the security and management needed to keep that identity private. And it does so in a way that is compliant to regulations, providing a real and necessary solution to the challenges users and companies face, and will continue to face as more and more parts of life go online.

Pada September 2020, Dusk Network mencapai titik balik penting—bukan melalui pembaruan protokol atau perubahan konsensus, tetapi melalui investasi strategis dari iFinex Inc., perusahaan induk Bitfinex. Investasi ini, yang mencapai lebih dari 1 juta dolar AS, bertujuan untuk mempercepat pengembangan bursa token yang diatur yang dibangun di atas infrastruktur blockchain yang menjaga privasi Dusk.
Langkah ini menandai sinyal jelas bagi pasar: Dusk sedang menempatkan diri sebagai infrastruktur untuk aset keuangan dunia nyata yang sesuai peraturan, bukan sekadar blockchain fokus privasi lainnya.

Seiring dengan perkembangan protokol As Dusk Network menuju tahap berikutnya dari Testnet, kesempatan unik muncul bagi mereka yang memiliki semangat (dan kecerdikan) untuk terlibat dalam proses ini. Testnet yang berjalan secara berkelanjutan dengan insentif akan disertai oleh berbagai inisiatif, masing-masing menambah keamanan jaringan dan membuka pintu bagi kompensasi bagi para peserta, sekaligus mendidik komunitas tentang apa yang dibutuhkan untuk menjadi peserta dalam protokol Dusk Network. Jika Anda ingin menghabiskan waktu Anda untuk memperkuat kerangka keuangan masa depan sambil mengumpulkan hadiah, teruslah membaca untuk mengetahui lebih lanjut.

Dunia kripto secara terus-menerus berayun antara dua ideal inti yang sering bersaing: transparansi dan privasi. Meskipun ledger publik seperti Bitcoin dan Ethereum menawarkan transparansi yang belum pernah ada sebelumnya, sekelompok proyek yang dikenal sebagai "koin privasi" muncul untuk memenuhi visi awal cypherpunk tentang uang digital—tidak dapat dilacak, dapat dipertukarkan secara setara, dan bersifat pribadi. Namun, perjalanan aset-aset ini mengalami turbulensi signifikan. Jadi, apa yang terjadi dengan koin privasi, dan apa artinya perubahan ini bagi proyek seperti Dusk Network?

Peraturan ini bertujuan untuk memberikan kejelasan dan pengawasan terhadap industri kripto dengan memperkenalkan persyaratan lisensi bagi bursa dan penyedia dompet, serta menetapkan kewajiban untuk mencatat informasi pengirim dan penerima transaksi, terlepas dari jumlah transaksi. Mengingat perkembangan ini, muncul pertanyaan mengenai implikasinya terhadap Dusk dan perusahaan kripto serupa yang beroperasi dengan protokol fokus privasi di UE dengan kondisi berikut sebagai ringkasan:
- Semua bursa dan penyedia dompet harus memiliki lisensi.
