OneLedger enables you to focus building your business application through OneLedger modularization tools, which will communicate with OneLedger protocol using its API gateway. This mechanism will make your business application interact with different public and private blockchains synchronously through corresponding side chains implemented in OneLedger platform. OneLedger defines a three-layer consensus protocol to enable more effective integration of different blockchain applications. Business logic can be implemented by the first layer – a configurable role-based consensus protocol leveraging hierarchical grouping similar to the structure of Merkle Tree. The side chain consensus protocol can move consensus traffic from the main chain with public consensus to the side chain with high performance and efficiency. OneLedger block structure enables the synchronization and reference between the three-layer consensus. The company works as a cross-ledger blockchain platform for people to make exchanges through business methodology. Not only that, but it’s also developed using the enterprise blockchain technology solutions that are running across the globe like something the world has never seen. One Ledger also operates as a powerful consensus engine that will help people with governance, so they can rest assured their transactions are being completed legitimately. The SDK on the platform is also highly customizable. And the platform, in general, is highly scalable and reliable. The architecture of the One Leger is built around the focal point of building your business software through the One Ledger modularization tools. They are set up to communicate with One Leger’s advanced protocol via the unique API gateway used by the platform developers. The new method of operation is designed to make your business application work together with different private and public blockchains in synchronicity by way of side chains that work together and are implemented via the One Ledger platform. The platform is designed to help people in a wide range of different business models. People in finance, agriculture, transportation, manufacturing and just about anything else will benefit highly from the One Ledger protocol. It works with Bitcoin, Ethereum, HyperLedger and several other platforms.
Nxt uses the blockchain to create an entire ecosystem of decentralized features, all of which require the Nxt currency. Instead of modifying the original Bitcoin source code, as many altcoins have done, Nxt developers wrote their own code in Java from scratch. While Nxt is a public blockchain, licenses for private blockchains based on its software are also available for purchase. The developers refer to Nxt as Blockchain 2.0, providing numerous applications beyond simply keeping a public ledger of transactions. Jelurida BV took over the originally anonymously developed Nxt and now own the IP rights. Kristina Kalcheva, co-founder and legal expert of Jelurida, focuses on how to “explore the different open source licensing models and their enforceability in practice.” Currently, the main developer is an anonymous Star Trek fan, going by the name Jean-Luc Picard. While there is still the active development of Nxt, the parent company Jelurida is also working on a Nxt 2.0, known as Ardor, designed specifically to deal with scalability. Ardor will use the same blockchain technology as Nxt, combined with the idea of ‘child chains.’ According to Travin Keith, Nxt foundation Web and Marketing manager, Ardor allows for a “manageable blockchain size, which solves the problem of scalability by separating transactions and data that do not affect security from those that do, and moving all of those that don’t affect security onto child chains.” The core infrastructure of Nxt is complex. This adds risks as compared to the more lean bitcoin, but makes it easier for external services to be built on top of the blockchain. A peer-peer exchange allowing decentralized trading of shares, crypto assets. Since the blockchain is an unalterable public ledger of transactions, the Asset Exchange provides a trading record for items other than Nxt. To do this, Nxt allows the designation or ''coloring'' of a particular coin, which builds a bridge from the virtual crypto-currency world to the physical world. The ''colored coin'' can represent property, stocks/bonds, commodities, or even concepts. Arbitrary Messages enable the sending of encrypted or plain text, which can also function to send and store up to 1000 bytes of data permanently, or 42 kilobytes of data for a limited amount of time. As a result, it can be used to build file-sharing services, decentralized applications, and higher-level Nxt services. Nxt had no mining phase, all initial units were released to 73 people through a one-time fundraiser via bitcoins, after the announcement of the NXT project in the bitcointalk-forums by BCnext. Combine this with a PoS approach, and you have a situation where the big guys run the table. At one point, the Nxt community had a very public spat with Bitcoin developer Jeff Garzik. Garzik took issue with the Nxt marketing approach, its anonymous developers, and their responses to constructive criticism. Nxt responded to some of these claims, of course, but it remains one of the more controversial moments in its history. Another key problem the Nxt network ran into (like so many others) was blockchain bloat. Nodes get weighed down by the onerous task of having to store every transaction on the Nxt blockchain. This was one reason (among others) why Ardor/Ignis came into existence.'
