Chainlink - Tout ce que vous devez savoir

Chainlink est une solution décentralisée basée sur Ethereum pour la vérification des soi-disant oracles. Les oracles sont utilisés par les plates-formes de contrats intelligents pour cartographier les informations externes du «monde réel» nécessaires à l'exécution d'un contrat. L'approche de Chainlink promet d'améliorer la sélection et la disponibilité d'oracles fiables.

Quel problème résout Chainlink?

Contrats intelligents basés sur BlockchainsRéaliser cela pose toujours des défis pour les développeurs. L'exécution des transactions contractuelles dans un écosystème clairement défini est le moindre des problèmes. Parce que c'est exactement pour cela que le concept de blockchain a finalement été développé.

Plusieurs choses rendent ChainLink unique. C'est un théorie dédié uniquement à rendre intelligente des contrats plus connectés au monde externe. Le contrat concept wise a été initialement introduit par Ethereum; cependant, leurs contrats intelligents peuvent seulement gérer data about la blockchain. En sachant le prix link, vous pouvez connaître la valeur de ChainLink.

La plateforme crypto chainlink tente de contrer ce problème en mettant en place une plateforme de trading décentralisée pour les services Oracle. Les développeurs s'appuient initialement sur le réseau éprouvé, mais souhaitent externaliser une grande partie des fonctionnalités de la blockchain à moyen terme. Il s'agit de maintenir les coûts d'utilisation du marché bas. Les transactions en chaîne doivent être payées avec le jeton Ethereum "LINK".

Comment fonctionnent les oracles chez Chainlink?

Tout comme les oracles de la mythologie, qui promettaient à ceux qui cherchaient de l'aide la connaissance et les prophéties en invoquant une autorité supérieure, les oracles dans les contrats intelligents servent également de source externe fiable pour les informations relatives au contrat. Dans le cas du pari de football décrit ci-dessus et présenté dans un contrat intelligent, il peut s'agir, par exemple, d'un site Web proposant des résultats de jeu sous une forme lisible par machine. Un contrat intelligent peut lire ces informations et, en fonction de cela, payer à l'un des partenaires contractuels après le match.

Si l'enjeu n'est pas trop élevé et que le site Web est digne de confiance, cette méthode est un bon moyen de cartographier les paris sportifs dans un contrat intelligent. En règle générale, l'opérateur de l'oracle facturera une somme modique pour la fourniture des informations. Mais que se passe-t-il s'il s'agit de beaucoup d'argent et que la possibilité pour le fournisseur Oracle de corrompre ou de déformer des messages est intéressante?

Dans ces cas, il est judicieux d'utiliser les informations de plusieurs oracles indépendants pour le jugement. Ce n'est que lorsque, par exemple, quatre sites Web différents rapportent à l'unanimité le résultat du match de football, le contrat est effectivement exécuté. Cependant, cette approche présente l'inconvénient que la sélection et le paiement des oracles deviennent de plus en plus complexes et coûteux. D'autant que non seulement la fiabilité des informations doit être garantie.

L'approche de Chainlink

Chainlink est une approche pour organiser l'offre de services Oracle via la blockchain et pour les placer sur une base de confiance. La solution mise en œuvre par Ethereum est destinée à fournir trois mécanismes importants en chaîne afin de permettre la sélection des oracles appropriés. D'une part, il existe une gestion de la réputation des fournisseurs Oracle.

Dans ce cadre, les trois critères définis dans la dernière section pour un Oracle fiable sont évalués: l'intégrité, la disponibilité et la confidentialité. D'autre part, Chainlink dispose des fonctionnalités nécessaires pour permettre d'une part la mise en relation entre les partenaires contractuels intelligents et les fournisseurs Oracle et d'autre part pour cartographier l'agrégation des offres contractuelles.

Les développeurs de Chainlink soulignent dans le livre blanc, qui décrit la gamme de fonctions prévue de la plateforme, qu'il devrait être possible à moyen terme de réaliser de grandes parties du service actuellement en chaîne, également en dehors de la blockchain Ethereum.

How To Choose An Iron With A Steam Generator?

More and more often, housewives prefer a whole ironing system to an ordinary iron. Choosing an iron with a steam generator is not a simple task, because the model range is quite wide, and each manufacturer praises its product.

What iron is better with a steam generator?

If you do not have acquaintances who are already using steam irons and can give advice, it is better to give preference to companies that have no problems.

Often, in the line of one type of technology, several different models are presented at once. In this case, you can pay attention to irons with a built-in steam generator. The cost will be slightly lower, but the characteristics will be different.

When deciding which iron to choose with a steam generator, pay attention to the iron tip . At first glance, this criterion has little effect on choice at all. But the sharp-nosed model more qualitatively strokes the place between the buttons, but the stubborn model leaves almost no doubts on the clothes.

Rating of irons with steam generators

There is also such an assessment. In a way, this is a great tip for you when choosing an iron. It is clear that the popularity of the model depends on the quality of the product, the price and the popularity of the company, but even one brand has fewer models of the same type of household appliance.

How to Use Spray-On Bed Liner

Apart from human transportation, land transportation to transport goods from time to time has developed quite significantly. Currently, the pickup or double-cabin fleet of vehicles has recorded a fairly rapid increase every year. But this time what we are discussing is the best bed liner which is now one of the mandatory accessories for d-cab and pickup owners.

As a vehicle for transporting goods, more or less will experience friction with the goods it transports. Paint peeling off due to friction will open the metal surface of the plate. So that the

Under-controlled circumstances, like in a spray enclosure with proper venting and environmental controllers, the two aspects of a polyurethane or polyurea system are drawn from their individual storage drums or tanks into spray processing products. Both main elements of the machine, both the diisocyanate as well as also the polyol, are emptied from the processing devices and fed into some hand-held spray weapon. The reactive components fit, mix and therefore are applied from the trained and properly protected applicator. In DamnTools, you can find best truck bed liner.

iron plate is in direct contact with air which will trigger oxidation. Rust must have quickly approached that section. Within a certain period of time the iron plate will be eroded and eventually porous.

In order to prevent this from happening, several efforts were made to essentially protect the surface of the cargo tub from collisions and scratches. One of them is by adding a bed liner, aka the protective layer of the surface like goods.

The most primitive way is by placing a wooden plank on the surface of the tub. The wooden planks will protect from direct friction from objects that are transported by the surface of the tub plate.

So far we haven't found a seller that specifically offers this pioneering generation of bed liners.

You could say this is a home made bed liner.

Although it is quite effective and the price is relatively affordable, it is lacking in terms of aesthetics.

Especially if the wood is worn out and begins to break. Surely the display is getting less and less okay. Another downside of this wooden bed liner is that it doesn't protect the vertical sides of the tub. So that not a few floors like the pickup of the vehicle are intact but the sides of the walls are in shambles.

But of course this is not what we mean by bed liner. There are at least two types of bed liners that are widely known throughout the world. Both have the same use, but are completely different in form.

Drop-In

The first is a plastic bed liner called a drop-in bed liner. This bed liner is able to protect all sides of the existing tub. The surface of the pickup plate plate can be protected from impact or friction. Aesthetically, its appearance does not interfere with the beauty of the design of the vehicle it is installed in.

Generally, this type of drop-in is made of shatter-resistant plastic, but some are made of polyurethane. This type is quite strong and durable without special treatment for maintenance. In other words, maintenance free. Some sources say that this drop-in bed liner can withstand the harsh weather outside the garage for up to 10 years.

However, even this bed liner has a fairly basic weakness. This protector can only be transferred to similar vehicles with the same pickup specifications. This bed liner size is made specifically for one type of product only. "The single cab drop-in bed liner certainly cannot be used on a double cab, and vice versa," said Migrawan Nugroho, a double cab user from Bekasi. "The drop-in bed liner is very specific for each brand and type of vehicle," continued the man who is a fan of this modification.

The thing that makes the minus value comes from the towering purchase price that is very expensive to make up for the drop-in bed liner, besides that it is possible for water to break in and get trapped between the bed liner and the surface of the tub. Usually this water comes from the part of the bed liner that is cracked, broken and due to condensation.

Over its useful life, the drop-in bed liner will lose strength. Brittle and undergoes changes in shape and structure to become a scourge that haunts this one species after its age has been sufficiently eroded.

Spray-on

It is called Spray-on, because it is applied by spraying it. Even though it is labeled as spray on / in, in practice this type can be applied with a roll brush.  

Maybe in Indonesia, this type of one is not widely found. However, in America this type is one type of bed liner which is quite popular.

One of the things that makes it quite popular is because of the flexibility in its use of applications. will cover," explained Iyan Daniel from the Autotrek workshop in the Leuwinanggung Cibubur area.

This type of spray on can be said to have a dual function. Besides functioning as a coating (bed liner) it also has water repellent properties. So it is not wrong if this one system has a dual function. Apart from being a coating it also has a role to keep water from rising to the surface of the plate," added Iyan. And one more advantage, that the color can be chosen as you wish.

The difference between the basic material between Polyurethane and Polyurea affects the quality of the bed liner, especially its resistance to friction or impact from other objects. Polyurea is a material developed from polyurethane and has better durability and durability than its predecessor. It is not wrong that Polyurea coatings were widely applied by the military.

"Another drawback, obviously there is the scarcity of materials and tools that cannot be obtained easily," Iyan concluded, showing the special spray gun used in the on / in spray.

Choosing The Best Material For Pegboard Hooks

In addition to the plug-in board itself, the pins are the most important element of the material. They make it possible to act as a shelf from which tools or goods can be hung. Pegboard has become eponymous for any type of perforated hardboard intended for the setting of pins or hooks.

In addition to the plug-in board itself, the pin pins are the most important element of the material. They make it possible to act as a shelf from which tools or goods can be hung. Pegboard is indeed a brand name, although it has become eponymous for any type of perforated hardboard intended for the setting of pegboard hooks.

Pegboard is just anyplace - hooks, panels doo dads , you name it. Every handtool at the hardware-store is hanging on pegboard. Each and every bag of bolts, roll of duct tape and tin of TicTacs at the checkout counter-pegboarded. Even the peg board hang on 1/4 inch pegboard hooks. But that will come as no surprise. Retailers want a display system which's hardy, simple to re arrange and adaptable-the exactly same qualities you need in your work spaces in your household.

Function of pegboard

Pegboards are practically big slabs. Hooks go towards these pegs to hold tools, materials and goods. In the correct arrangement, 2-4 pegs can support almost any tool in a workshop. In stores, pegboards are often used to display goods, primarily using hooks.

Choosing the best pegboard pin material

The material used for the pegboard pins does not always match the material used for the pin board. Metal hooks are often used in conjunction with wood composite panels. The stuff you use with your pegboard setup will mainly depend on what support is needed. In a workshop, heavy tools may require steel or brass pins, while wooden pins may be sufficient for lighter tools. Another factor to consider is the size of the holes in the breadboard. It can ban what materials work as pens. For example, brass pins may not be available in the size you need.

Metal pins

Metal pins, including brass, are the best choices, but they're also the most expensive. Machined pens are quite labor intensive, which adds to the cost. However, their strength is not achieved by wood. For heavy tools hanging from a perforated panel, metal pins are the best choice. Metal hooks work too. They come in a variety of lengths and sizes and are useful for almost any tool. The quick and easy way to attach them to the pegboard ensures secure support for whatever you hang.

Wooden pegs

As an alternative to metal, wooden pegs also work in pegboards. Since the holes pre-drilled in perforated panels are no more than ¼ inch in diameter, multiple wooden pins are required to carry heavier tools. Wooden dowels are strong, although if they are very heavy, they will not be enough to carry the heaviest tools you will hang from the board if not attached with extra pegs.

Your basic choice for pegboard pegs is made of metal or wood. While metal pins are stronger, they are more expensive and can put a strain on the pegboard if used to carry too much weight. Wooden pegs are less expensive, but their ability to support tools on pegboard comes into question the heavier the weight.
