Blockchain interoperability is the ability for different blockchain networks to communicate and interact with each other. As the number of blockchain networks increases, it's becoming increasingly important to understand how to create cross-chain communication and how to use different interoperability solutions. This is important to create a decentralized ecosystem of blockchain networks, where different networks can share information and assets with each other. One of the key challenges in achieving interoperability is the fact that different blockchain networks use different protocols and consensus mechanisms. This can make it difficult for them to communicate and share information with each other. To overcome this challenge, several solutions have been proposed, such as atomic swaps and cross-chain messaging. There are several different types of interoperability solutions available, each with their own benefits and limitations. - Atomic swaps: This is a type of smart contract that allows for the exchange of one cryptocurrency for another without the need for a centralized intermediary. This allows for the direct exchange of assets between different blockchain networks. - Cross-chain messaging: This is a way for different blockchain networks to share information and communicate with each other. This is done by sending messages between different networks through a messaging protocol. - Middleware: This is a type of solution that acts as a bridge between different networks. This can include blockchain hubs, which can handle the translation of data and assets between different networks, making it easier for them to communicate and share information. - Sidechains: This is a solution that allows for the creation of a parallel blockchain that runs in parallel with an existing blockchain. This allows for the transfer of assets between the main blockchain and the sidechain, creating a form of interoperability. - Protocol-based solutions: This type of solution allows multiple blockchain networks to use the same protocols, which allows them to interact with each other. Examples of this are Cosmos, Polkadot, and Aion - Hybrid solutions: This type of solution combines the benefits of different interoperability solutions to create a comprehensive solution. An example of this is the Interledger Protocol (ILP) which is an open protocol stack for interoperability between ledgers of any type and complexity. - Oracles: Oracles are intermediaries that can facilitate the transfer of information between different blockchain networks. Oracles can be used to facilitate cross-chain communication, and can be used to provide information from off-chain sources to smart contracts on-chain. - Interoperability frameworks: This type of solution is a set of protocols, standards and practices that allow different blockchain networks to interact with each other in a cohesive and seamless way. How do these solutions work and what are their benefits and limitations? Atomic swaps: - Atomic swaps work by creating a smart contract that allows two parties to exchange assets in a trustless and decentralized manner.

What are the key challenges in achieving interoperability? There are several key challenges in achieving interoperability between different blockchain networks, some of which include: - Technical compatibility: Different blockchain networks use different consensus mechanisms, data structures, and programming languages. This can make it difficult to establish a common protocol that allows them to communicate and share information. - Security: Interoperability solutions need to be secure and able to protect against attacks such as front-running, and data breaches. - Scalability: Interoperability solutions need to be able to handle high transaction volumes and large amounts of data to ensure they can function effectively. - Governance: Interoperability solutions require a governance model to ensure that all participants can agree on how the solution will be managed and maintained. - Privacy: Interoperability solutions need to take into account the privacy requirements of different networks and ensure that sensitive information is protected. - Regulation: Interoperability solutions need to comply with the regulations of different jurisdictions, which can vary widely and make it difficult to create a global solution. - Adoption: Interoperability solutions need to be adopted by a sufficient number of users to be effective. This can be challenging as blockchain networks need to trust one another, and it can be difficult to establish trust between networks that have different governance models and underlying technologies. - User experience: Interoperability solutions need to be easy to use and understand, otherwise, it can discourage users from adopting it. How can we ensure the security and integrity of data and assets when they are exchanged between different blockchain networks? Ensuring the security and integrity of data and assets when they are exchanged between different blockchain networks is a key challenge that needs to be addressed. Some of the ways to achieve this include: - Cryptography: Cryptography is used to secure the data and assets being exchanged between different blockchain networks. This can include the use of digital signatures, hash functions, and encryption to ensure that only authorized parties can access the data and assets. - Smart Contracts: Smart contracts are self-executing contracts with the terms of the agreement written into code, can be used to ensure the security and integrity of data and assets by automating the execution of the contract and the transfer of assets. Smart contracts can be used to ensure that the conditions specified in the contract are met before the assets are transferred. - Interoperability solutions: Interoperability solutions such as atomic swaps and cross-chain messaging, are designed to ensure the security and integrity of data and assets when they are exchanged between different blockchain networks. These solutions use cryptographic techniques to ensure that only authorized parties can access the data and assets. - Multi-signature: Multi-signature is a security measure that requires more than one private key to authorize a transaction. This can help to prevent unauthorized access to data and assets by requiring multiple parties to sign off on the transaction. - Security Audits: Regular security audits can help to identify vulnerabilities and weaknesses in the interoperability solutions, which can then be addressed before they are exploited by attackers. - Monitoring: Continuously monitoring the network for any suspicious activity can help to detect and prevent attacks on the interoperability solutions. - Governance: A governance model that ensures the participation of all stakeholders, and ensures that there is a way to resolve disputes and make decisions, can help to ensure the security and integrity of data and assets when they are exchanged between different blockchain networks. - Insurance: To ensure that losses are covered in case of an attack on the interoperability solutions, insurance can be used as a risk management strategy.

Im Januar 2019 soll ein neuer ERC20-Token auf der Ethereum-Blockchain eingeführt werden, der eins zu eins durch Bitcoin gedeckt ist. Kyber Network (KNC), Republic Protocol (REN) und BitGO haben sich dafür zusammengeschlossen und Wrapped Bitcoin (WBTC) entwickelt. Bitcoin und Ethereum haben schon immer unabhängig voneinander gearbeitet. Während Atomic Swaps und Interoperabilitätsprotokolle seit einiger Zeit in der Entwicklung sind, ist die vollständige Kompatibilität zwischen Netzwerken, deren Code einander fremd ist, eine komplexe Aufgabe. Dieses Problem möchte das neue Projekt Wrapped Bitcoin (WBTC) lösen, indem es einen ERC20-Token, den WBTC, bereitstellt, der durch „physische“ Reserven von BTC gesichert ist und voraussichtlich an den Wert von Bitcoin gebunden bleibt. Zu den Unternehmen, die hinter Wrapped Bitcoin stehen, gehören die dezentralen Börsen Kyber Network und Republic Protocol, sowie der Krypto-Verwahrer BitGo. Darüber hinaus unterstützen eine Reihe von Ethereum-basierten Projekten die Einführung des Token. Dazu gehören andere dezentrale Kryptowährungsbörsen und anderen Ethereum-Projekte, wie Airswap, Ddex, Hydrogen, Set Protocol, Compound, MakerDAO, Dharma, Prycto, Idex, Gnosis, Radar Relay und Blockfolio. Auf der Webseite von Wrapped Bitcoin heißt es: WBTC standardisiert Bitcoin auf das ERC20-Format und schafft so Smart Contracts für Bitcoin. Das macht es einfacher, Smart Contracts zu schreiben, die Bitcoin-Transfers integrieren. Das Ethereum-Netzwerk verarbeitet Transaktionen schneller als das Bitcoin-Netzwerk, sodass Bitcoin-Inhaber nicht mehr warten müssen. Mit WBTC ist der Wechsel von Bitcoin zwischen den Börsen viel schneller. Ziel ist des Projektes ist es also den Nutzen von Bitcoin in der Art und Weise zu replizieren, dass BTC mit Ethereum interoperabel ist und somit dezentrale Anwendungen und Smart Contracts für Bitcoin bzw. dessen ERC20-Token-Repräsentation entwickelt werden können. Loi Luu, Mitbegründer und CEO von Kyber Network sagte zu dem Projekt: Diese Initiative wird die Liquidität von Bitcoin und das umfangreiche Smart Contract Developer Ökosystem von Ethereum zusammenführen. Anwendungen auf Ethereum wie dezentrale Börsen und Finanzprotokolle werden alle in der Lage sein, Bitcoin nahtlos zu nutzen und Bitcoin-Handelspaare zu schaffen, die bisher unmöglich waren. Gleichzeitig wird der Einsatz von Bitcoin durch dezentralere Anwendungsfälle wie Börsen, Kredite, Tokenzahlungen erweitert. Da Wrapped Bitcoin (WBTC) eins zu eins durch Reserven in Bitcoin gedeckt ist, bedarf es eines Verwahrers. Dies wird BitGo als Hauptverwahrer sein, der eine Reserve von Bitcoins hält, um alle geprägten WBTC-Token, die sich im Umlauf befinden, auf der Ethereum-Blockkette zu sichern. Langfristig sollen weitere Depotbanken und Händler als Verwahrer dienen, um das Wachstum des Projektes zu fördern. Zu diesem Zweck soll eine dezentrale autonome Organisation (DAO) aktiviert und mit der Überwachung der weiteren Entwicklung des Projekts beauftragt werden. DAO-Mitglieder werden über zukünftige Entwicklungen und alle vorgeschlagenen Verbesserungen abstimmen und entscheiden können. Davon unabhängig sollen die Reserven in Bitcoin über eine Webseite und alle Adressen der BTC für jedermann nachprüfbar sein. The post Wrapped Bitcoin (WBTC) erscheint im Januar 2019 auf der Ethereum Blockchain appeared first on Coin Hero. Lesen Sie den ganzen Artikel

OOOBTC, a Singapore based cryptocurrency exchange is taking a step ahead to enhance security and user experience by enabling cross-chain transactions on their platform. Being the first major exchange to introduce this feature, they are giving a real challenge to fellow centralized exchanges. Their move to atomic cross chain transactions comes along with the wave of several exchanges to become decentralized and putting the power back into the hands of their users. Centralized exchanges can easily become breeding grounds for hackers. Once the exchange has become vulnerable, it is nearly impossible for its users to withdraw their funds during security breaches. Atomic cross chain transactions will aid users with more secured transactions. With centralized exchanges, users are at the platform's mercy at any given time. If at any time an exchange were to shut down or lose funds, there is nothing a user can do to retrieve their funds back. Because of this, many are exclaiming that atomic swaps could cause a large, potential threat to exchanges and the current way they operate. OOOBTC's cross chain atomic swaps or "atomic swaps" will allow 2 parties to maintain their funds on their own blockchain and complete crypto-based trades. These types of trades can happen instantaneously. To ensure the security and reliability of atomic swaps enabled transactions, OOOBTC exchange has created a smart contract to assist in more trustworthy actions. Through hash-time locked smart contracts, this will further help to ensure that the trade between the two parties is conducted successfully. "While atomic swaps provide a solution, this alone will not end centralized exchanges any time soon. With the cryptocurrency space still somewhat in its infancy, exchanges are trying to be user-friendly instead of being tech-friendly, where, in fact, both should go hand in hand" a spokesperson of the exchange explained. "The crypto world changes rapidly all around us. In order to continue to thrive as a business over the decades and beyond, we must look forward, walk in the forefront of the world. That's why we would like to do our best to provide an exchange that's secure, reliable, fast and user-friendly" quotes the team. OOOBTC has always been committed to creating user value as the goal, to provide global crypto users with a faster and more convenient trading model. They have recently announced the integration of BlockBar, the first blockchain based search engine to help their users to track transactions. More details about BlockBar can be found at https://blockbar.com OOOBTC is the world's leading cryptocurrency exchange that primarily supports three trading pairs: BTC, ETH, and USDT. It is fairly new to the cryptocurrency space and aims to provide efficiency and excellent performance for it users. The exchange uses safety measures by using cold storage & 2-factor authentication. OOOBTC will be the first exchange to offer atomic swaps. A major move that will put them ahead of the curve from their competitors.

Usually, less popular altcoins rely on proof-of-work protocols. This makes individual networks vulnerable to attacks as the ones that took place in the previous months. The most important question is how to secure these networks. Komodo suggests that delayed proof of work (dPoW) might do the trick. Though this is not an original idea, by all means, it is deployed in just a handful of altcoins. Furthermore, Komodo team insists this feature is not that hard to deploy in already existing networks at all. However, there is a catch. You should pay Komodo for it. For the price of 100 KMD (roughly $250), every single altcoin can get protection against 51% attacks. Needless to say, nobody knows if the Komodo-developed solution works on every scale. After all, it is not popular, meaning it may have its security flaws. Another question that arises is whether Komodo is doing right to charge for something that is usually open source. Komodo is definitely deploying interesting ideas in the otherwise conservative blockchain world. It strives to provide better liquidity for altcoins that are not listed by the commercial exchanges through atomic swaps. The idea is to enable the token transfers from one blockchain directly to another. This omits the need for exchanges in general. Still, only time will tell whether atomic swaps and dPoW can solve part of the problems associated with low-hashrate altcoins. Read the full article
