price_step

Cardano has over 30 network parameters–the mechanisms that control how the Cardano Blockchain works. In this installment of our ongoing exploration of Cardano's network parameters, we turn our attention to **price_step**, one half of the critical executionPrices configuration that determines how much users pay for smart contract operations. While its partner price_mem governs the cost of memory usage, **price_step** sets the price for computational processing power—every logical operation, cryptographic calculation, and algorithmic step executed by Plutus scripts. As of December...

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...

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...

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...

Au moment de l'enregistrement, Cardano dispose d'environ 30 paramètres de réseau. Ces paramètres sont les mécanismes qui contrôlent le fonctionnement de la blockchain Cardano. **Aujourd'hui, nous parlons d'un paramètre qui détermine une grande partie de l'activité quotidienne du réseau et de la communauté Cardano, à savoir la **'epoch_length'. ## Epochs Tout d'abord, qu'est-ce qu'une époque ? En termes simples, une époque est une unité de temps. Les époques de la Terre sont des périodes géologiques mesurées en dizaines de milliers...

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...

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 [link post_id=153]decentralization parameter[/link], 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,...

optimal_pool_count

Of all the parameters guiding Cardano, few spark as much debate as **optimal_pool_count** — better known as k. Cardano has over 40 parameters shaping its security, performance, and governance. So why does k get so much attention? ### What is optimal_pool_count (k)? The **optimal_pool_count (k)** is a protocol parameter that defines the ideal minimum number of stake pools to efficiently run the Cardano network. It enforces this ideal minimum by influencing how delegation incentives are structured. In a proof-of-work (PoW)...

gov_action_deposit

In September 2024 Cardano bootstrapped its efforts to transition to on-chain governance with the Chang hardfork major software update. Since September there’s been a number of additional big milestones including: * 50 global workshops to co-create a constitution * A constitution convention in Argentina and Kenya * A second hardfork to enable Cardano holders to propose 7 different types of governance changes, including proposing withdrawals from the treasury. * Intersect and Pragma, which are two Cardano Members-Based Organizations, create two...

## 2025: The Completion of Cardano’s Original Roadmap This year marks the completion of Cardano’s original development roadmap. Since the beginning, Cardano’s progress has been guided by its three founding entities. These entities defined the roadmap and set the network’s parameters based on rigorous research. Parameters are the settings that define how the blockchain operates. Over the years, some parameters have been adjusted. In some cases, the changes were part of the original plan—like the gradual phasing out of the...

min_pool_cost

Cardano has over 30 parameters. Each parameter plays a role in shaping the network’s functionality, governance, economics, and performance. The **min_pool_cost** parameter was a point of consternation for many within the Cardano community for a long time. Here is what the parameter does, and why you might care. ## What is it The **min_pool_cost** sets a **minimum fixed fee** that every stake pool operator (SPO) must charge to run a pool. ## Why a Minimum Cost? Running a stake pool...
