One-stop Storage Solution for NFT with Flexible Metadata Engine

Issues with NFT Storage
NFT no doubt is the hottest topic in the current decentralized world but the current storage of NFT underlying resources cannot yet be solved on the chain itself. On one hand, the cost of storage on the mainstream blockchain is extremely high. On the other hand, existing decentralized storage solutions are mostly cold-storage and cannot provide metadata-relevant storage and query solutions, resulting in low usage experience.

What is CATA?
CATA provides a complete one-stop solution for Dapp data storage. CATA creatively extends the IPFS (InterPlanetary File System) protocol to provide decentralized storage while achieving flexible metadata management, and is also compatible with SQL queries, providing extremely user-friendly and developer-friendly data access.

CATA Interaction with FLOW
CATA has designed a set of interaction protocols for Flow's Cadence contract layer, enabling integration and full traceability of token transactions and data storage, providing a one-stop solution for NFT publishing, storage, management and distribution. It is fully compatible with Cadence's resource-oriented capabilities, allowing Cadence developers to easily connect NFT contracts to storage facilities.

Core Concept

The current decentralized network is still far from true production deployment, and the scenarios that can be truly implemented today are extremely limited. The main reason for this is the lack of infrastructure. Although throughput of public blockchain increased significantly the storage protocol itself is still at an early stage. Storage solutions in the traditional world often consider both storage and retrieval, but the current mainstream of decentralized storage (such as IPFS, Filecoin) is almost pure storage, which cannot meet the requirements of data retrieval and content delivery. And some bandwidth-based data distribution projects (such as Meson Network) are also difficult to meet flexible query requirements.
CATA project begins in 2015 with goal of developing a more powerful distributed storage protocol and providing more flexible and user-friendly features for the storage system to create a more complete infrastructure forthe decentralized world.
The underlying layer of CATA is a general decentralized file system that accounts for storage and retrieval capabilities. Above the file system layer, CATA provides a flexible metadata management engine. In the current phase, CATA will leverage NFT as the first use case and collaborate with Flow Blockchain to provide users with a one-stop NFT platform.

Distributed Storage and Retrieval: as a fundamental capability of decentralized storage, data should be persistently stored on the network and ensure permanent availability. In addition, the CATA protocol guarantees high storage performance, supports reading and writing large amounts of data, and achieves practical cost. Compared to cold storage, CATA puts more design energy on retrieval and supports content-based flexible queries (instead of just file download) to meet fine-grained data organization requirements (e.g., NFT classification retrieval).

Metadata Engine: on top of the underlying decentralized file system, CATA has developed an independent metadata layer, Minerva. Minerva combines the serverless query engine with the underlying storage protocol. The CATA node is not only a storage resource provider, but also a service provider for the query engine. It is responsible for storing and querying structured metadata as well as parsing and tasking query requests. Therefore, users can flexibly define and decentrally manage structured and fine-grained metadata. At the same time, Minerva provides support for SQL queries, supports indexing, sorting, searching, and other semantics to meet the needs of Dapp developers, and minimizes dependency on centralized storage solutions.

Full lifecycle solution for NFT storage: the current NFT scenario relies on blockchain networks (e.g., Flow or ETH) to build a marketplace, and metadata storage often relies on centralized storage solutions (e.g., AWS), or content is stored on a decentralized storage protocol (e.g., IPFS) and then linked to the on-chain marketplace through additional operations, which negatively impacts the NFT user experience. The CATA storage protocol extends from the circulation layer on the blockchain, the Minerva metadata layer, to the underlying system layer, covering the business logic of NFT data storage, the associations between the on-chain and Off-chain worlds, and the entire process of token circulation. It provides a one-stop NFT experience.

CATA Distribution
The total number of CATA tokens we plan to issue is 20,000,000 for network building and community governance. And the CATA tokens are required to be distributed to the world in the following manner.
1. Mining. A portion of the tokens will be distributed  as network incentives to workers who provide hardware resources to the CATA network.
2. Ecosystem Building. A portion of the tokens will be used for ecosystem building such as incentives for qualified contributors. Also, a portion of the tokens will be set aside for subscriptions by institutions and community participants.
3. Team&Foundation Reservation: A portion of the tokens will be used to build the technical team and cover the operational costs.
4. Signup Educational Program: The purpose of the program is to spread knowledge of decentralized storage around the world, and enable more users and Dapps to experience the new manner of decentralized storage service provided by CATA .Our goal is to reach as many people and decentralized projects as possible with our educational programs before running out of funds.
5. Bitcoin Program: A portion of the tokens will be set aside to be distributed to holders of Bitcoin and Flow to build early reputation in the existing decentralized community as well as in the mainstream NFT community.

Community Ambassador Recruitment
CATA is a community driven project and offers incentives for expanding the community.
Anyone who participates in CATA community development (construction and management) and meet corresponding standards will be awarded with privilege for token sale.
They need to establish a community for management and meet corresponding standards, Community ambassadors can get the amount of early-stage community financing and participate in the early-stage construction and development of CATA. At the same time they have to contribute to CATA, build a community and manage it. The screening system should be as strict as possible.

There is now an incredible amount of smart money in Bitcoin:

Bitcoin is not just the playground of speculators, the reality is that the best programmers and most powerful business people in the world see the potential in Bitcoin.

9  Economy / Speculation / We will now test $274.64 - Downtrend until April 2015 on: October 04, 2014, 12:28:14 PM
I believe we are either in a huge downtrend, that is no where near finished, or a rally will emerge out of no where and create its own trend lines.  We do not seem to be following any trend

We are also going to test the high of the previous rally imminently

Pretty basic TA, but includes no bullshit  Wink  I also want to self-moderate this thread to keep falllling out

10  Bitcoin / Bitcoin Discussion / Will we ever know Satoshi's next project? on: October 03, 2014, 02:49:34 PM
He/she/they said they moved on from Bitcoin to work on other projects.

Will there be an announcement somewhere saying "Glad you like Bitcoin, let me know your thoughts on this side project I have been working on"?

Do the opposite of what the market is saying.

Right now I see everyone saying the final capitulation is coming and there are so many shorters.

I am going to add 10 or so coins to my collection  Wink

Idiots in China
17  Bitcoin / Bitcoin Discussion / Will Bitcoin be 'hacked' by September 2015? on: September 17, 2014, 05:05:06 PM
I went to Inside Bitcoins this week.

There was a cryptographer ( ) presenting and he predicted this:

"The digital signature scheme of bitcoin with SHA256+secp256k1 ECDSA will be broken before 1 September 2015 by cryptography researchers.
The attack should allow to forge digital signatures for at least a proportion of 1/1 million bitcoin users and steal money from them.
It should be done faster than 2^100 point additions total including the time to examine the data."

You can see the details of it here:

What do others think of this?

Self explanatory subject
19  Other / Meta / Official list of fallling's sock puppet acccounts on: September 10, 2014, 11:59:42 AM
As Blitz does not want to take any action against fallling, it is only fair that we compile a list so the genuine newbies know who to ignore.

So here is the Speculation board recommend ignore list / all of fallling's known duplicate accounts:
fonzie (people who have been around for a while remember that fonzie was his orginal account, then he seemed to migrate his trolling to fallling.  His fonzie account does not do much trolling at the moment, but it is still the same kid in India operating it)

I wish to self-moderate this thread

I think to keep this thread constructive and not a witch hunt, we need to supply evidence.

'Evidence' shall constitute new accounts spreading doom, using the same language that fallling is infamous for such as:
"cut your loose"
Calling every price rise a dead cat bounce
"final capitulation"
"Bitcoin is going nowhere but down"

"ETF will be shot"
