BitBay is a free, decentralized marketplace for buying and selling goods and services on the blockchain. You can connect directly with peers and transact without the need for a middleman like Amazon, eBay, or Craigslist. Transactions are secure and anonymous. They’re also guaranteed by escrow. The project aims to be the new standard for eCommerce, allowing individuals to trade one-to-one at scale. As a result, BitBay claims it will revolutionize global trade. It’s seemingly a great solution for other niche applications as well, where groups of people aren’t served by existing marketplaces. In the beginning, BitBay got off to a rocky start. In 2014, the original founders raised capital in bad faith and quickly abandoned the project after fundraising, leaving the lead developer holding the bag. It seemed like BitBay was finished, but the developer continued working on the project out of a sense of duty to the original investors, without access to the capital raised in the fundraising round. The BAY token is the transactional token in the marketplace. You use it to buy and sell, and it can also participate in freezes, escrow, bets, swaps, etc. The token itself operates like Bitcoin and is secured by the network. Although you can use BAY for transactions, you don’t have to. You do, however, have to use BAY if you’d like to take part in token staking. BAY’s price cratered after the original founders left and stayed low until March 2017 when it took off. It has been through several cycles of bull and bear runs, with a max price over 30 cents in January 2018 before retreating to its current value. BitBay supports all kinds of privacy and security measures. It’s easy to create a multisignature wallet for added security. There are integrations for Tor and other proxies that help anonymize your connection to the marketplace. An on-screen keyboard allows for password or key entry without using your keyboard and being susceptible to keylogging. Additionally, you can create images with your private key embedded, so that finding a stored key is more difficult for a hacker. The marketplace also has functionality for time locking contracts and swapping currencies. This enables all kinds of cross-chain transactions and financial implements. The time lock and other smart contract elements make it possible to create bets, escrow, futures and options trades, or any number of other financial transactions. The idea and implementation by BitBay, of a decentralized marketplace and trading platform is brilliant and shows further promise of expansion.The rocky beginning of the cryptocurrency and its subsequent comeback as a promising platform indicate that the developers are in it for the long haul and don’t plan on abandoning the platform after all these years.
ChainLink is a decentralized oracle service, the first of its kind. When Ethereum went live in 2015, it revolutionized what blockchain could bring to enterprise solution and traditional business. Blockchain was no longer just a medium for new age financial transaction, confined to Bitcoin’s potential to disrupt traditional currency exchange. With Ethereum powered smart contracts, Vitalik Buterin opened up a Pandora’s Box of use cases for blockchain technology. Problem is, per their design, smart contracts can only manage data on the blockchain. Their potential, the ability to provide tamperproof, decentralized applications for uses the world over, is still largely untapped, as many of the smart contract programs built on Ethereum lack a bridge to the real world industries they’re trying to improve. ChainLink’s first component consists of on-chain contracts deployed on Ethereum’s blockchain. These oracle contracts process the data requests of users looking to take advantage of the network’s oracle services. If a user or entity wants access to off-chain data, they submit a user contract (or requesting contract) to ChainLink’s network, and the blockchain processes these requests into their own contracts. These contracts are responsible for matching the requesting contract up with the appropriate oracles. The contracts include a reputation contract, an order-matching contract, and an aggregating contract. The first of these, the reputation contract, is exactly as it sounds: it checks an oracle provider’s track record to verify its integrity. In turn, the order-matching contract logs the user contract’s service level agreement on the network and collects bids from responsible oracle providers. Finally, the aggregating contract accumulates the collective data of the chosen oracles and balances them to find the most accurate result. Unfortunately, the ChainLink team does not offer a roadmap, but a testnet of ChainLink’s services should come sometime within Q1 of 2018. Generally, the project’s general lack of marketing and concrete updates have frustrated community members in the past. Sergey Nazarov, the project’s CEO, is known for a quiet community presence that favors of behind-the-scenes work on ChainLink. The team may not hype their project much, but for what it’s worth, they sacrifice brand marketing in favor of product development–and some community members find this focus to be refreshing. For instance, they’ve established an oracle with Swift Bank, and have a few quiet partnerships with zepplin_os and Request Network. Chainlink has the potential to connect smart contracts with the outside world. It may allow parties to smart contracts to be able to receive external inputs that prove performance and create payment outputs that end users want to receive, such as bank payments. This has the potential to allow smart contract to mimic the vast majority of financial agreements currently available in the market. With the ChainLink Network, anyone can securely provide smart contracts with access to key external data and any other API capabilities, in exchange for financial reward. Although it remains to be seen how the incentive system will operate, there is potential for rewards similar to those available for crypto miners to be available to Node Operators that provide useful data to the Chainlink network.'
