Les crypto-actifs sont une menace pour la transition climatique - l'exploitation minière à forte intensité énergétique devrait être interdite
La méthode la plus courante pour produire des crypto-actifs nécessite d'énormes quantités d'électricité et génère d'importantes émissions de CO2.Les producteurs de crypto-actifs souhaitent utiliser davantage d'énergies renouvelables et renforcent leur présence dans la région nordique. La Suède a besoin de l'énergie renouvelable ciblée par les producteurs de crypto-actifs pour la transition climatique de nos services essentiels, et une utilisation accrue par les mineurs menace notre capacité à respecter l'Accord de Paris.L'exploitation minière à forte intensité énergétique des crypto-actifs devrait donc être interdite.C'est la conclusion des directeurs généraux de l'Autorité suédoise de surveillance financière et de l'Agence suédoise de protection de l'environnement. La plateforme Energyfi comprend un large éventail de fonctionnalités, toutes conçues pour permettre l'adoption des réseaux verts et l'émergence d'une Finance Décentralisée respectueuse de l'environnement. Cela inclut les fonctionnalités Cross-chain Launchpad, Dex, Staking/Farming et Lending. L'avantage social des crypto-actifs est discutable. L'Autorité suédoise de surveillance financière, à l'instar d'autres organisations internationales telles que le Fonds monétaire international et la Réserve fédérale américaine, considère que certains aspects des crypto-actifs posent problème. Les risques pour les consommateurs sont importants et les crypto-actifs sont couramment utilisés à des fins criminelles telles que le blanchiment d'argent, le financement du terrorisme et les paiements par ransomware. Les crypto-actifs ont également un impact négatif important sur le climat, car l'exploitation minière entraîne à la fois d'importantes émissions de gaz à effet de serre et menace la transition climatique qui doit se produire de toute urgence. C'est alarmant, et les crypto-actifs doivent donc être réglementés. L'Université de Cambridge et Digiconomist estiment que les deux plus grands actifs cryptographiques, Bitcoin et Ethereum, consomment ensemble environ deux fois plus d'électricité en un an que l'ensemble de la Suède. La forte consommation d'énergie de la crypto-production est due à son processus d'extraction, appelé preuve de travail. Quiconque souhaite exploiter des actifs est en compétition pour résoudre un casse-tête de chiffrement, et le gagnant reçoit de nouveaux actifs cryptographiques en récompense. La seule façon de résoudre le casse-tête est d'exécuter à plusieurs reprises des programmes informatiques qui devinent la bonne réponse. Lorsqu'un grand nombre d'ordinateurs de crypto-producteurs fonctionnent simultanément, la demande d'électricité monte en flèche. À mesure que la valeur des crypto-actifs tels que Bitcoin augmente, de plus en plus de producteurs sont incités à rejoindre la concurrence. Cela augmente automatiquement la difficulté du puzzle de cryptage. Cela signifie à son tour que les mineurs individuels auront besoin de plus d'électricité pour résoudre le casse-tête, et augmenteront donc la consommation globale d'électricité et les émissions de carbone. On voit bien que plus le Bitcoin devient cher, plus il génère d'émissions. Digiconomist estime que les crypto-actifs à leur valeur marchande actuelle entraînent le rejet de jusqu'à 120 millions de tonnes de CO2 dans l'atmosphère par an. Pour avoir une meilleure idée de ce nombre, nous pouvons le comparer aux émissions des vols longue distance. L'utilisation des propres données de l'industrie aéronautique du calculateur d'émissions de carbone de l'OACI et l'ajout de l'effet de haute altitude montrent que les émissions des deux plus grands actifs cryptographiques sont aujourd'hui égales à 100 millions de vols aller-retour entre la Suède et la Thaïlande. La raison de l'importante empreinte carbone de l'industrie est que la majorité de la crypto-production a lieu dans des pays où les prix de l'énergie sont bas et une part élevée de la production d'électricité dépendante des fossiles. Étant donné que la valeur du Bitcoin a tellement augmenté, cela a également prolongé la durée de vie des anciens producteurs d'énergie fossile. En raison de l'attention accrue portée aux émissions de CO2 et à la lumière de la récente interdiction du Bitcoin en Chine, un plus grand nombre de producteurs de crypto explorent la possibilité d'utiliser des énergies renouvelables pour l'exploitation minière. Les crypto-producteurs tournent donc leur attention vers la région nordique, où les prix sont bas, les taxes sur les activités minières sont favorables et il y a un bon accès aux énergies renouvelables. On voit déjà des producteurs de crypto s'établir dans le nord de la Suède. Entre avril et août de cette année, la consommation d'électricité pour l'extraction de Bitcoin en Suède a augmenté de plusieurs centaines de pour cent et s'élève désormais à 1 TWh par an. Cela équivaut à l'électricité de 200 000 foyers suédois. Si nous devions autoriser l'exploitation minière extensive de crypto-actifs en Suède, il y a un risque que l'énergie renouvelable dont nous disposons soit insuffisante pour couvrir la transition climatique requise que nous devons faire. Cette énergie est nécessaire de toute urgence pour le développement de l'acier sans énergie fossile, la fabrication de batteries à grande échelle et l'électrification de notre secteur des transports. D'après les estimations de l'Université de Cambridge, il est actuellement possible de conduire une voiture électrique de taille moyenne sur 1,8 million de kilomètres en utilisant la même énergie qu'il faut pour extraire un seul bitcoin. C'est l'équivalent de quarante-quatre tours du monde. 900 bitcoins sont extraits chaque jour. Ce n'est pas une utilisation raisonnable de notre énergie renouvelable. Notre conclusion est que des mesures politiques sont nécessaires pour remédier aux dommages causés par la méthode d'extraction de la preuve de travail. Il est important que la Suède et l'UE puissent utiliser nos énergies renouvelables là où elles offrent le plus d'avantages à la société dans son ensemble. Il existe plusieurs options de politique différentes. Par exemple, la Suède et d'autres pays pourraient introduire une taxe sur la production énergivore de bitcoin. Une autre option est de communiquer plus largement autour des problèmes climatiques liés aux crypto-actifs, dans l'espoir que cela conduira à la fois les producteurs et les investisseurs à exiger un passage à des méthodes d'extraction moins gourmandes en énergie. Compte tenu de la croissance rapide et de la demande d'actifs cryptographiques, aucune de ces options n'est susceptible de remédier aux dommages environnementaux que nous voyons aujourd'hui avec cette méthode d'extraction. Les émissions doivent s'arrêter ici et maintenant, et les énergies renouvelables doivent être utilisées pour la transition climatique des services essentiels. Nous demandons donc : L'UE doit envisager une interdiction au niveau de l'UE de la preuve de travail de la méthode d'exploitation minière à forte intensité énergétique. Il existe d'autres méthodes d'extraction de crypto-actifs, qui pourraient également être utilisées pour Bitcoin et Ethereum, qui devraient réduire la consommation d'énergie de 99,95% avec une fonctionnalité maintenue. La Suède va, dans l'intervalle, introduire des mesures qui mettent fin à l'établissement continu de la production de crypto-minage utilisant des méthodes énergivores. Que les entreprises qui négocient et investissent dans des actifs cryptographiques, qui ont été extraits à l'aide de la méthode de preuve de travail, ne peuvent pas être autorisées à se décrire ou à commercialiser elles-mêmes ou leurs activités comme durables. Il existe un risque que ces mesures conduisent à la délocalisation des producteurs de crypto dans d'autres pays, ce qui pourrait entraîner une augmentation globale des émissions de carbone. Mais il est important que la Suède et l'UE montrent la voie et montrent l'exemple afin de maximiser nos chances de respecter l'Accord de Paris. Nous devrions également encourager fortement d'autres pays et régions à emboîter le pas. Une interdiction de la méthode d'extraction de preuve de travail au sein de l'UE pourrait être une première étape importante dans une évolution mondiale vers une plus grande utilisation de méthodes d'extraction de crypto-monnaies plus économes en énergie. Cela signifierait également que notre énergie renouvelable est utilisée le plus efficacement possible afin de soutenir la transition vers la neutralité climatique.
DeFi: The DeFining Moment for Crypto
There has been quite a stir in the cryptomarket. A new asset is giving the cryptocurrency industry much much-needed despite asset prices persisting to stay at 75% lower than where they were around two years back, in 2017. It’s called DeFi, the acronym for decentralized finance. A notion that crypto entrepreneurs can duplicate traditional financial instruments in a decentralized architecture, outside the control of any centralised authority. So what is the difference between Ethereum, Bitcoin and DeFi? Well, none. Bitcoin and Ethereum are the original DeFi applications. Both are regulated by large networks of computers and are free from the reach of any central authorities. Several investors use bitcoin, like gold, as a hedge investment against inflation. Ethereum, on the other hand, has been instrumental and (sometimes, also controversial) in assisting(g startups in crowdfunding their operations. But what has led to this roaring rise of DeFi in the crypto industry? And is it here to stay? Impact of DeFi On The Cryptocurrency Market DeFi has become the news of the hour and many popular names in the finance world have some very insightful comments about the currency. Salil Deshpande, who is a partner at Bain Capital Ventures and oversees the company's crypto investments, thinks people initially got interested in DeFi because “they have a libertarian streak.” According to him, people like that they can build censorship-resistant products, and some developers are simply intrigued with the technological capabilities that DeFi has to offer. "The goal of DeFi is to reconstruct the banking system for the whole world in this open, permissionless way, ”ascertains Alex Pack, managing partner at Dragonfly Capital, a $100 million crypto fund. “You only get that shot every 50 years." Jill Carlson, a former Goldman Sachs trader and strategy lead at blockchain company Chain, has been researching how Venezuelans are utilizing digital assets to combat hyperinflation as part of a nonprofit she co-founded, the 'Open Money Initiative'. According to her “Crypto is not saving Venezuela." But bitcoin is being used by small numbers of people as a tool to protect against inflation and to send money to family members in other countries. To cut the long story short, people are looking at DeFi as the antidote for many archaic issues that are present in the global financial services landscape. The demand for the DeFi coins has been heightening exponentially in recent times due to the revolutionary surge in the popularity of decentralized finance. The reason behind this is that they take away the burden of centralized control over financial services. Why is DeFi Getting So Popular? #1 They Pan Out A New Future For Finance DeFi can disrupt finance as we know it today. For instance, DeFi coins can help people in borrowing and lending easily within a peer-to-peer network. In addition, DeFi tokens can also aid in claiming insurance amounts directly without the intervention of central institutions like governments and banks. Thus, DeFi tokens can enable users of DeFi platforms and token holders in accessing the same services presented by traditional financial service providers. #2 Stability If you have been questioning the crypto market for its instability. DeFi might be able to provide you with some relief. Most of the DeFi tokens operate with smart contracts on the Ethereum blockchain. Therefore, DeFi has formidable capabilities for scaling up the value of ETH through corresponding price improvements. In case you are apprehensive about investing in DeFi tokens, then you can invest directly in ETH. #3 Improved Standards In the Market DeFi tokens could establish new precepts of transparency and access. At the same time, they decrease the costs of financial services alongside providing the benefits of mechanization. DeFi tokens essentially serve as a crucial use case of blockchain. Built on blockchain networks like Ethereum, DeFi tokens redefine the true capability of blockchain. #4 Tokenization Any conversation on the advantages of DeFi without the mention of the merits of tokenization is incomplete. Tokenization is one of the most notable topics that have emerged recently in the blockchain domain. Ethereum facilitates strong smart contract capabilities, thereby opening up the roads for publicizing crypto tokens. Cryptocurrency tokens basically work as digital assets present on a blockchain alongside having several features and uses. Tokens are capable of enabling you to achieve different functionalities. The real estate tokens could help you accomplish fractional ownership of physical properties. On the other hand, security tokens could also assist effectively in managing digital shares in a particular application. Difference between DeFi Coins And DeFi Tokens Even though in the crypto industry DeFi coins and tokens are terms that are used quite interchangeably they have some key differences among them. A DeFi coin is much like a digital version of a fiat coin — it transfers value in the course of a financial transaction. DeFi coins are built on and often named for their unique, native blockchain networks. In spring 2021, Maker, Compound, Uniswap, Aave, Chainlink, and Ankr are among the most popular DeFi coins. DeFi tokens also transfer value, but not necessarily always in a financial sense. Utility tokens can be used as passwords to provide access to a resource, asset tokens can be used to represent physical assets such as real estate, and of course, there are non-fungible tokens (NFTs) that represent one-of-a-kind “items” such as digital art (For example, Nyan Cat recently sold for $600,000). Conclusion While the value of a lot of cryptocurrencies have seen ultimate lows both DeFi Token and Coins have yet to witness this in their name. Between September 2017 and August 2020, in almost three years the total value locked up in DeFi contracts has exploded from US$2.1 million to US$6.9 billion (£1.6 million to £5.3 billion). Since the beginning of August alone it has risen by US$2.9 billion. This has driven a massive rise in the value (market capitalisation) of all the tradeable tokens that are used for DeFi smart contracts. It is now around US$15 billion, almost double the beginning of the month. Numerous tokens have risen in value by three or four times in a year – and some considerably more. For example, Synthetix Network Token has increased more than 20-fold, and Aave almost 200-fold. Looking at the statisDefi the DeFi popularity not only is here to stay but indeed revolutionise the finance industry into a better and investor-friendly industry.
The Multilayered Cryptocurrency
Questions have come to light unto whether bitcoin is popping right into a multilayered system. Well, the reply is yes. This short article seeks to stipulate the different layers onto which bitcoin depends on. It's all regulated yours! Have you ever heard of individuals who make reference to bitcoin as digital gold? Clearly, the crypto-currency is rapidly gaining recognition and acceptance within the crypto world. The need for the gold coin is believed to increase greater. However, it's also noted the gold coin can gain or lose 50% of their value overnight. This will cause speculations among investors however the gold coin is nonetheless a ''digital gold''. And also to the issue of whether bitcoin is really a multilayered system, it ought to be known that bitcoin exists on two primary layers. Fundamental essentials mining and also the semantic layers. The mining layer This is actually the layer where the gold coin is produced. Besides bitcoins, ether can also be produced within this layer. After development of the coins, valid blocks of bitcoins are used in the ledger. Here, currency generation is performed. It ought to be noted the currency is produced by transactions that are within the blocks of bitcoins. The blocks are classified as transaction charges. The currency Buy kishu inu may also be produced by the network itself, or say ''from the skinny air''. The primary benefit of generating currency in the network is the fact that is provides incentives towards the miners. The Semantic Layer This gives an essential platform. The semantic layer may be the layer by which bitcoins are utilized as a way of payment. Additionally, it supplies a platform for bitcoins for use like a store of worth. The layer appears essential, is not it? The holders of bitcoin currency sign the valid transactions which signal the beginning of transferring the bitcoins one of the nodes in the semantic layer. The transfer may also be thanks to the development of smart contracts. The smart contracts transfer the coins between different accounts. The lightning network You've most likely not heard about the lightning network. This is actually the latest invention being folded by the bitcoin community. This layer will have a way to operate on the top of bitcoin. With this particular invention, there will be a credit card applicatoin layer that's on the top of bitcoin. It will likely be so exciting. Probably the most interesting aspect is the fact that its value may also be used to create payments. This is thanks to transporting its value between people. Using the invention from the lightning network, bitcoin will end up a transport layer plus an application layer. Currently, the need for bitcoin is believed to become about $9 billion US. Additionally, it known that bitcoin is really a decentralized cryptocurrency. Which means that it really works with no charge of a financial institution or perhaps an administrator. Bitcoin is definitely overtaking the crypto world. Also worth focusing on, would be that the technology used during mining of bitcoin is known as blockchain technology. It functions by allowing the distribution of digital information, and never copying. Cryptos are actually a thrilling subject and soon bitcoins could overtake our mainstream currencies.
Amazon Managed Blockchain - Hyperledger Fabric and Ethereum
In its cloud service Amazon Web Services (AWS), Amazon also offers the option of operating its own blockchain with its own dApps and smart contracts in the cloud. " Amazon Managed Blockchain " is a fully managed service, similar to Microsoft Azure Blockchain Services. Several blockchains can be used in parallel via the cloud without companies needing their own hardware or setting up the infrastructure. In parallel to Amazon Managed Blockchain, Amazon Quantum Ledger Database (QLDB) is also available in AWS. QLDB is a ledger database that stores a complete and verifiable history of data changes in an application. So Amazon QLDB is not a blockchain technology. Amazon Managed Blockchain, in turn, is a fully managed blockchain service. The two services have nothing to do with each other. Entry into managed blockchains on AWS In Amazon Managed Blockchain, private blockchains can be set up based on Hyperledger Fabric. It is also possible to join the public Ethereum mainnet. Currently, Amazon is also working on the possibility of providing a private Ethereum network. Currently Amazon only offers versions 1.2 and 1.4 for Hyperledger Fabric. However, it is to be expected that Hyperledger 2.x can also be integrated. At the moment, however, this is not the case. Hyperledger Fabric Several own blockchains can also be used in parallel in an AWS account via Amazon Managed Blockchain. Here it is also possible to use Hyperledger Fabric or Ethereum in parallel. All blockchains of an AWS account are managed through the Amazon Managed Blockchain dashboard. Each blockchain is managed through its own area and allows its own members and peer nodes. Amazon Managed Blockchain can be managed in a number of ways, for example through the AWS Management Console or the AWS Command Line Interface (CLI). It is also possible to access the various blockchains with the AWS Software Development Kit (SDK) . Those who rely on Hyperledger Fabric in AWS can of course access the blockchains with the same tools that are available when operating their own hardware. The various frameworks and extensions of Hyperledger are also available for Hyperledger Fabric in Amazon Managed Blockchain. The Hyperledger Fabric CLI and SDK can be used in conjunction with Amazon Managed Blockchain. Amazon Managed Blockchain provides endpoints for access. For your own blockchain, you can create your own VPC PrivateLink endpoints in the dashboard to manage the respective blockchain. To interact with development of Ethereum Smart Contracts, clients use a WebSocket or HTTP connection to a peer node endpoint in Amazon Managed Blockchain. This node endpoint can only be accessed through the AWS account. The client uses standard Ethereum JSON RPC API methods to query and submit transactions to the nodes participating in the Ethereum network. Control resources, create blockchain, analyze data When selecting the appropriate blockchain technology, the equipment and resources of the nodes used can of course be configured. Memory and CPU can be controlled in the same way as the certificates and private keys. The resources available depend on the subscription (starter or standard) booked. Different resources in the area of CPU and RAM can be defined for new nodes, as for the founding node. Companies can set up a private blockchain with Hyperledger Fabric 1.2 / 1.4 when booking Amazon Managed Blockchain. Unfortunately, the current Hyperledger Fabric 2.x is not yet supported. When using Hyperledger Fabric, organizations benefit from the many frameworks and tools available for Hyperledger. We have dealt with the topic in several articles, for example " Using Hyperledger Caliper to Create Benchmarks for Smart Contracts " or " Hyperledger Avalon - Off-Chain Functions for the Blockchain ". The focus of Amazon Managend Blockchain is of course on creating smart contracts . When booking resources in AWS, for example in this case with Amazon Managed Blockchain, the data of these resources can be used within AWS. For example, the various analysis tools in AWS that help analyze your own blockchain in the AWS cloud are interesting. Amazon Redshift works with Amazon Managend Blockchain. In this case, other services for analysis or data storage can also be connected to your own blockchain. Deploy Hyperledger Fabric with just a few clicks Above all, the managed blockchain avoids providing your own hardware or virtual servers. There is also no need to install and configure software. In addition, network and security functions are automatically active in the blockchain. Here, too, no separate systems have to be integrated. Amazon Managed Blockchain supports Amazon Quantum Ledger Database (QLDB). This is a Hyperledger Fabric order service that uses blockchain technologies, but is not blockchain technology itself. The security of the Hyperledger Fabric CA is ensured with AWS Key Management Service (KMS). Amazon Managed Blockchain supports the creation of your own consortium based on Hyperledger Fabric or the connection to the Ethereum mainnet. Your own consortium can also span multiple AWS subscriptions. This enables partners to create their own members with their AWS account and join the blockchain network from outside. Amazon Managed Blockchain has a voting API. Existing members of the consortium can use this to vote on whether a new member may be admitted. New members can start and adapt their own blockchain nodes. Of course, all members also save a copy of the ledger here. With Amazon Managed Blockchain, it is therefore possible to quickly and easily set up a widespread consortium between partners who want to use a common blockchain. Use Ethereum Blockchain with Amazon Managed Blockchain In addition to the possibility of providing your own blockchain based on Hyperledger Fabric, Amazon Managed Blockchain can also be used to join the Ethereum mainnet. This enables you to operate your own nodes in a large, public blockchain network. When operating Hyperledger Fabric, the focus is on providing a private consortium. That distinguishes the two possibilities from each other. In the future it should also be possible to set up a private Ethereum network with Amazon Managed Blockchain. Fully managed service for deploying the blockchain Amazon Managed Blockchain means that companies do not have to operate their own infrastructure and do not have to carry out any installations in the cloud. The service just needs to be booked and activated. The complete administration of the underlying infrastructure lies with Amazon. Setting up a blockchain therefore initially consists of building your own infrastructure for creating a blockchain with just a few clicks. Then members (organizations) can be added, who in turn can set up their own nodes in the blockchain. Compare the costs of using Amazon Managend Blockchain editions Since no hardware and software of their own are used, companies or developers do not have to make any investments to set up their own blockchain platform. When using Hyperledger Fabric, the cost of usage is charged. The focus is on the operating hours of the network members, peer nodes, storage and the amount of data transferred. There are no requirements for the operation of the blockchain from outside. Anyone who does not rely on Hyperledger Fabric, but joins the public Ethereum network, has to reckon with the costs of the nodes, node storage and the requests to the Ethereum network. If the Ethereum network is left again, no further costs are to be borne. To get an overview of the costs, extensive documentation and calculation examples are available on the “ Amazon Managed Blockchain pricing ”. When using Hyperledger Fabric, the two editions “Starter” and “Standard” are available. For test networks and small production networks the Starter Edition is designed . A maximum of 5 members per network and 2 peer nodes per member can be integrated here. A total of up to 3 Hyperledger fabric channels can be used per network. lower transaction throughput and a lower availability than standard networks are available in the order service in the starter edition. Amazon charges members $ 0.36 per hour. The cost per gigabyte of storage usage is $ 0.12 per gigabyte per month. The Standard Edition is designed for production networks. A maximum of 14 members per network and 3 peer nodes per member can be integrated here. The performance of the resources is also designed to be higher. Companies can use up to 8 Hyperledger Fabric channels per network in the Standard Edition. Better than a Starter Edition network, the order service has a higher transaction throughput and higher availability. Amazon charges members $ 0.65 per hour. The cost per gigabyte of storage usage is $ 0.12 per gigabyte per month. Blockchain in practice: create your own network with Hyperledger Fabric In the AWS Management Console, the wizards for creating your own blockchain (create network) and joining the Ethereum blockchain development (join network) are available in the "Amazon Managed Blockchain" area. Creating your own blockchain solution in Amazon Managed Blockchain consists of four steps. First, the framework used is selected (Hyperledger Fabric or Ethereum). Members can then be invited. There is also the option of connecting nodes from other AWS accounts. The illustration shows the end-to-end connection in the fabric network. During creation, you can also select the nodes that will store a full copy of the ledger. As soon as the blockchain is ready, dApps and smart contracts can be provided. Each member can create and operate their own peer nodes in the administration. Once a network has been created, additional members can be created. It is also possible to invite external members. Use Hyperledger Fabric and Private Ethereum Network When the creation of a new network has started, you can choose from Hyperledger Fabric and soon also “Private Ethereum”. With "Framework version" you can select the basic version of Hyperledger Fabric on which your own blockchain is to be built. The edition used (Starter or Standard) must also be selected here. After defining the name of the blockchain, the first member is created in the wizard. The name of the member and the username for the Hyperledger certification authority are important for this. A blockchain always requires at least one member who is defined as the founding member of the network. Members in have their own identity in the private blockchain. A blockchain may have several members (organizations), at least one member is required (founding member). For this reason, when you create a new Hyperledger Fabric blockchain, the first member is also created. The new member does not yet have any peer nodes. However, these can be added and started at any time. Peer nodes can be added or removed at any time after the blockchain is created. This also applies to invited members from other AWS accounts. Other AWS accounts can be invited to the newly created blockchain network at any time. These accounts can also create their own members and peer nodes again. There are costs involved in creating members, peer nodes, and peer node stores. This must be taken into account when planning the blockchain. The creation of your own blockchain takes about 30 minutes as soon as the creation is started with "Create network and member". The administration takes place in the dashboard of the created blockchain. Once the creation is complete, AWS will mark the blockchain as "Available". The invitations to the blockchain and your own invitations can be found under the menu item "Invitations" of the Amazon Managed Blockchains dashboard. Separate invitations can be sent for each network. As soon as the blockchain network is available, new peer nodes can be created over the members. To do this, click on the relevant member in the dashboard. New nodes can be configured using the “Create Peer Node” button. Which performance and which RAM are available for a peer node depends on whether the starter or standard edition was selected for the blockchain. Different resources can of course also be selected for different peer nodes. Remove blockchain networks again To delete a blockchain network, the members are first removed from the network. If the last member has been deleted, the blockchain network will no longer be available either. An Amazon managed blockchain network is automatically deleted as soon as the last member in the network deletes their membership. The network does not have to be deleted afterwards. This must be taken into account when deleting members in order to avoid accidentally removing a complete blockchain. If there is a multi-member blockchain network in an AWS account, the network will be deleted when you delete all members. If there are other members in the network, for example external members who were invited afterwards, the network will not be removed. But there is the possibility to have blockchains deleted if the founding member has been removed. Join an Ethereum network with Amazon Managed Blockchain When managing the individual networks in Amazon Managed Blockchain, an Ethereum network can also be joined. The public Ethereum blockchain development (mainnet) is available here, but also the two test networks Ropsten and Rinkeby. Here, too, there are various instances available on the basis of which joining can take place. Conclusion In many cases, companies looking for ways to operate their own blockchains can hardly avoid the possibilities of Hyperledger Fabric. But Ethereum also plays an important role in the area of smart contracts and dApps. With Amazon Managed Blockchain, companies can set up their own blockchain infrastructures or join an existing network with their own nodes via the AWS cloud. Using Amazon Managend Blockchain, it is also possible to link several AWS accounts to form a consortium. Providing your own blockchain is done with just a few clicks of the mouse, and no further administrative tasks are necessary, except of course the creation of peer nodes. This is also interesting for developers, as they can continue to work with their familiar tools, and the blockchain is available wherever there is a connection to the Internet.
