Developer advocate of Polygon Xiangan He talks about Polygon development.
The ecosystem of polygon is huge.
Polygon value propositions and offerings (official website retrieved Jan 2022)
Polygon offerings (official website)
Easy for developers to change ethereum apps to use polygon.
[NEWS] Farming game causes rise in demand of Polygon network, increases fees.
"The rising demand is impacting the usability of the Polygon network. Gas fees have increased dramatically this week, with PolygonScan showing an average gas fee of nearly 764 Gwei on January 5. That's a dramatic increase over the average rate, which fell between 72 and 115 Gwei daily during the last week of December. In U.S. dollars, it means that a Polygon transaction fee has jumped from what's often a penny or less to as much as $0.50, depending on the complexity of the transaction. That's still a fraction of the price of an Ethereum mainnet transaction, but for games and other applications that utilize a lot of transactions, the fees can start to pile up for users. " - decrypt.co
|Polygon architecture layers|
As developers you will need to own a bit of $MATIC polygon token for bridge, transaction fees etc, example to deploy smart contract to the mainnet.

We love crypto. We are not quite FUD but that being said, there are some concerning incidents in crypto that you should be aware of. Big hacks, cheats, investors, NFT purchase losing money, rug pull, even seizing of equipment! Let's reveal some costly mistakes in crypto.
- Crypto being over leveraged, forced liquidation

- A user has received a significant discount, resulting in 1697 OHM instead of 59 OHM after bonding an OHM/DAI bond that was supposed to be closed off. "OlympusDAO is an experimental project in the cryptosphere. The DAO manages a token treasury that's used to back the OHM currency. The purpose of the treasury is to make sure the token maintains a certain floor price. If the token drops below that price, the assets in the treasury can be sold to buy back OHM tokens — with the goal to bring its price back above that mark."
- "The DAO uses a process for helping the token to stay above that mark called Bonding. The DAO buys assets from investors (to go into the treasury) and issues OHM tokens to replace them. These bonds usually get a 5-10% discount and the tokens are handing out after a vesting period, which is currently set to five days."
- Some already call the DAO a ponzi scheme like pool even before this incident
- OpenSea froze Bored Ape transactions https://cointelegraph.com/news/opensea-freezes-2-2m-of-stolen-bored-apes
- "QiDAO acknowledged the exploit via Twitter; however, the team stressed that the vesting contract was exploited through a vulnerability in Superfluid, a smart contracts framework on Ethereum that enables users to transfer assets on-chain, rather than QiDAO itself." https://decrypt.co/92375/vesting-contract-polygon-defi-protocol-qidao-exploited-13-million
- Decrypt “Ronin, the sidechain for NFT "play-to-earn" game Axie Infinity, has been hit with an exploit that drained $552 million in crypto from its bridge to Ethereum's mainnet. By the time the exploit was disclosed, the value of the crypto lost had increased to $622 million.“

Oxford flower 102 example
Data is already split into train and validation folder. For an additional 3rd dataset, we will need to make the decision to split from train or valid, depends on the prevalence of data, per class.
Within the folders, there are 102 folders, corresponding to the 102 classes of flowers. Some folders have more data, some classes/folders have fewer. The folder name is the numeric value of the flower class.
This is an example what the flower image data look like.
Most modern deep learning libraries have the capability to load and organize image data from folders, named with the correct conventions.

Use NFT, ENS .eth name for Fundraising. It's easy for donors (who understand crypto) to figure out the address. It's also transparent to track and re-distribute to additional charities. Cuts off the middle man fees and potential issues.
There are also NFTs that can change traits, they are changeable, they can grow, they can have names added later etc. Novatar for example (just an example, not endorsement, we don't know much about this NFT)
