Develop in a detailed and extensive way a post explaining some other Blockchain Oracle. (Chainlink will not be allowed)
What are the topics you should cover as a minimum?

Blockchain Oracle

Blockchain oracle bridges blockchain and the outside world thus off chain servers by verifying and feeding smart contracts with real time data thereby serving as an intermediate. This is because though blockchain technology was build to be independent, it has several limitations and one is that it can not access information from outside it network unless it utilizes an oracle. Off chain information's like the current temperature, market predictions and crypto prizes, supply chains and many more are relayed to the smart contract to ensure it efficacy.

There are Centralized and decentralized Oracles. Centralized oracle relies and receive data from a single source whiles a decentralized oracle relies on independent information from different sources. An example of centralized oracle is JustLink and Band Protocol and an exampe of centralized oracle is Provable.

Now let us go to the type of oracle; they are classified by the source, where the data is coming from and whether it is from a centralized or decentralized source.

• Hardware and Software oracle
• Outbound and Inbound oracle
• Human Oracles

Band Protocol

Soravis Srinawakoon is the founder of Band Protocol in 2014. It is a decentralized oracle and can be used on several blockchains making which uses smart contract. It utilizes the BandChain which is a public blockchain and it securely connects data from outside sources and API's with the blockchain to sooth smart contract operation. as part of the Cosmost project, Band Protocol is able to communicate with several blockchains using the Inter-Blockchain Communication Protocol (IBC)

It main aim are multiple blockchain communication as I have mentioned, scalability, to release data flexibly and speed. transactions and validation on band is almost seemliness.

Band is the native token of the Band Protocol and is a ERC-20 token. According to Coinmarket, BAND was ranked at 158 among about 11,257 cryptos with a current price of $8.14 per BAND at the time of this assignment; The Market Cap was $285,435,993 and a fully Diluted Market Cap of $823,305,793; a 24 hour Volume of $54,927,559 and 35,191,821.00 BANDs currently circulating.You can buy and trade Band on this platforms: Binance, Huobi Global, OKEx, CoinTiger and Tokocrypto

Holding many Bands gives you the advantage to become a validator, or a network governance member when you stake your band tokens. Holders of less Bands token can choose to delegate their token to validators. Once a data is rectified, the validators is rewarded and the delegators are rewarded accordingly with Band token. This is possible because of the DPoS algorithm it employs. Data validators which fails to do it work is voted out of place and another replaced.

Use Cases

source

Mirror Protocol which deals in Synthetic assets partnered with Band Protocol to use it real time price feeds for it operations so investor will know the accurate prices of fungible tokens.

Band Protocol is also useful in Market prediction, Asset Management, Futures before this platforms will be useful to anyone.

Advantages AND Disadvantages

Advantages

• Band protocol is very economical as compared to chainlink so it favors those who patronize it use.
• It is very secured and reliable
• It helps feeds blockchains with off chain information which helps realize the full potential of smart contracts.
• It is very scalable and faster with validating data and feeding it to the chains
• Very useful for several blockchain platforms.
• One can participate in governance when you have enough BAND's
• Nodes are selected at random which is good to avoid data being compromised.

Disadvantages

• 7% to 20% inflation rate on token is too much to risk.
• at least 66% band token delegated to validators will ensure the rise of the token.
• Once the third parties sources are manipulated, it will affect the validity of informations being fed to smart contract.

Future developments and new projects

Here are some of the progress and the development Band protocol in onto. The images below are from: bandprotocol.com

Band protocol plans on widening it payment options in the coming upgrade and a standard for cross chain smart contracts and a "support for peer to peer authentication page". You can also review the snapshots for the several updates on the line.

Conclusion

I have really learned some awesome things about blockchain technologies and the need for a secured oracle which assist and sooths smart contract execution. Thanks for this lecture professor @allbert
