Monetary Expand Rate

Today we are talking about a parameter that is as old as currency and money itself. Our parameter today is the ‘**monetary_expand_rate**.’ This is the parameter that controls the rate at which Ada in reserve is put into circulation. Cardano’s currency has a fixed supply of 45 billion. However, not all 45 billion is available to the public to use. Initially, just over 31 Billion was released. The remaining amount was put into a reserve. Every five days, when incentivisation...

Le paramètre "D

À l'heure actuelle, Cardano dispose d'une trentaine de paramètres de réseau. Ces paramètres sont les mécanismes qui contrôlent le fonctionnement de la blockchain Cardano. Aujourd'hui, nous parlons de l'un des paramètres les plus anciens, le paramètre de décentralisation - également connu sous le nom de **paramètre "D "** Bien que le paramètre "D" ait maintenant été retiré, c'est une partie intéressante de l'histoire de l'origine de Cardano. ## Alors, à quoi servait-il ? Chaque blockchain commence par quelques personnes qui...

Époque Non

À l'heure actuelle, Cardano dispose d'une trentaine de paramètres de réseau. Les paramètres sont les mécanismes qui contrôlent le fonctionnement de la chaîne de blocs Cardano. Certains paramètres existent depuis le lancement de Cardano. Certains paramètres, comme le decentralization parameter, sont supprimés. D'autres fois, de nouveaux paramètres sont ajoutés. Plus souvent encore, la valeur d'un paramètre est modifiée. **Notre paramètre aujourd'hui est epoch_no.** Ce paramètre indique au système quand les autres changements de paramètres doivent prendre effet. Dans Cardano,...

Max Transaction Size

As of this recording, Cardano has around 30 network parameters. Parameters are the mechanisms that control HOW the Cardano Blockchain works. **Today we are talking about the max_tx_size parameter.** In episode 5 we learned about the parameter that controls how big each block that’s added to the Cardano blockchain can be. The other parameter that controls how much and what kinds of data can be stored on the Cardano blockchain is the max_tx_size, or the Max Transaction Size. The **max_tx_size**...

Pool Deposit

As of this recording, Cardano has around 30 network parameters. These parameters are the mechanisms that control how the Cardano Blockchain works. **Today we are talking about the *pool_deposit* parameter.** Cardano, unlike Bitcoin, is a Proof-of-Stake blockchain. On bitcoin, the blockchain is secured by expensive computer hardware using lots of electricity. These machines are distributed across the planet. Every time new data needs to be stored, 51% or more consensus is required among this global network of devices. The idea...

Les paramètres sont les mécanismes qui contrôlent le fonctionnement de la chaîne de blocs Cardano. **Aujourd'hui, nous parlons du paramètre max_block_size.

Dépôt de la clé

Au moment de l'enregistrement, Cardano a environ 30 paramètres de réseau. Les paramètres sont les mécanismes qui contrôlent le fonctionnement de la blockchain Cardano. Aujourd'hui, nous parlons d'un paramètre qui concerne tous les détenteurs d'ada souhaitant contribuer activement à la sécurité de Cardano. Notre paramètre d'aujourd'hui est le paramètre key_deposit. Avant de définir ce paramètre, plantons le décor : Cardano est une blockchain à preuve d'enjeu. Cela signifie que pour participer au maintien de la sécurité du réseau, vous n'avez...

cost_models (Plutus Script Execution Costs)

Any sophisticated computing system needs precise rules to manage resource allocation. Think about it – processing power, storage, and time are all valuable resources. They must be doled out fairly, and in a way that allows the system to work for everyone. Blockchain networks are no different. Consider these questions: + What should happen when someone submits a smart contract that is written in a way that it could consume unlimited resources? + How do you ensure the network remains...

Min Fee B

Cardano has around 30 network parameters. Parameters are the mechanisms that control how the Cardano Blockchain works. Today, we are exploring a parameter that serves as the foundation of Cardano's economic security model. Our parameter for the day is the **min_fee_b** parameter. In a previous installment in the series we wrote about its counterpart [**min_fee_a**](https://www.lidonation.com/en/posts/min-fee-a/). Unlike min_fee_a, which scales with transaction size, **min_fee_b** is more fundamental: the baseline cost that every single transaction must pay, regardless of its size or...

Min Fee A

Cardano has around 30 network parameters. Parameters are the mechanisms that control how the Cardano Blockchain works. Today, we are digging into a mechanism that plays an essential role in the Cardano transaction model. Our parameter for the day is the 'min_fee_a' parameter. At first glance, the naming might sound enigmatic, but the min_fee_a parameter plays a foundational role almost every time you sign a transaction. When a transaction is made on the Cardano network, a certain fee is associated...

Cardano has around 30 network parameters. Parameters are the mechanisms that control how the Cardano Blockchain works. Today we are talking about a parameter that every Ada holder should be aware of: ‘pool_retire_max_epoch’ or 'e_max.' Cardano stake pools are computer servers operated by individuals and entities around the world as part of a global connected permissionless network. This decentralized network processes transactions for Cardano, forming the Cardano blockchain. It is permissionless because anyone can set up a server and join...

Pool Pledge Influence

Cardano has over 40 network, economic, technical, and governance parameters. Some are updatable others are not unless you’re spinning up your own private Cardano chain in your lab. Most of the time, these parameters just run quietly in the background without fuss or controversy. A handful of them, however, spark lots of debate. https://www.lidonation.com/en/posts/optimal-pool-count/, is one famously polarizing parameter. Our parameter today, **pool_pledge_influence** (aka a₀ pronounced “a naught”), also falls in this small group of notoriously controversial parameters. ### Understanding...
