    Our network of investors brings us projects who need help recruiting someone who excels and speaking to the public. These projects are run by teams who are technically brilliant but have neglected the marketing side of business. They are all looking for someone to stand in and speak on their behalf in videos, zoom calls and possibly live events. These companies are all looking to start with $500 USD per month.

It should be an NFT webshop that offers different bidder models for sale, similar to OpenSea trading platforms: - temporary / time limited auctions - auctions without time limit - sales at fixed prices etc. From us would come the page structure, the texts, specifications and a rough graphic design. Everything else (especially the programming) would have to be developed and implemented by you. Can you give a rough estimate based on this information: 1) Can you implement a project like this in principle? 2) How long would it take? 3) What would be the total cost?

    ethereum fork -- 2 6 days left

    We are looking for the modified ethereum based transaction system with higher transactions per second with higher transactions throughput and lower transaction fee. We are looking for the DAG (Directed Acyclic Graph) to be the consensus algorithm which is faster, more tolerant, more reliable and cheaper transactions. The block timing will be the shorter and size somewhat higher to accept more transactions to be processed. The nodes can connect with the network and communicate. Our main aim is to increase the transactions speed and throughput with reduced transaction fee. If you can suggest other things which can be implemented to achieve the aim we are looking for, kindly suggest. The deliverables may include but not limited to the updated source code, binaries for deployment of the new...

    I've launched an NFT on $algorands Blockchain. As I'm starting to build a lot of traction for the project in looking at ways I could launch a game that would be similar to that of Nintendogs. So the player could add their unique NFT to the game and interact with the NFT such as feeding, itching, cuddling and just generally loving the Frenchie. Also I'm in contact with a small cap altcoin that could potentially sponsor the project so that we could implement mini games in the actual games where people compete against eachother. The weekly leaderboard will be calculated and the top 3 each week will receive either tokens or AlgoFrenchie merch.
