Treasury Growth Rate (τ)

Just like anyone can use the internet to put up a website, anyone can launch a blockchain network using some new or repurposed version of blockchain technology and software. But will it last? Will there be funding to feed it beyond the exciting launch phase? Will its decentralized participants be able to cooperate on decision-making? **These questions about sustainability and governance are at the core of the parameter we will be talking about today: the Treasury Growth Rate often denoted...

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...

pool_retire_max_epoch

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...

Gov Action Lifetime

## 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...

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...

Max Lovelace Supply

Cardano has over 40 parameters. Each parameter plays a role in shaping the network’s functionality, security, economics, and performance. The **max_lovelace_supply** parameter is one of a few parameters that are written in stone: designed to be non-updatable. Here is what **max_lovelace_supply** does, and why you might care. ### What is it The most critical parameter governing most digital assets on a blockchain system is its maximum supply—the hard limit on how many units of the currency can ever exist. 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)...

min_utxo_value

Cardano has over 40 network parameters. Parameters are the mechanisms that control how the Cardano Blockchain works. Today we will be digging into a parameter that comes into play every time you interact with your Cardano blockchain account: **min_utxo_value**. Have you ever noticed that your wallet has more ada than you are able to send? Or perhaps that when you’re filling in the ada amount to send, the wallet field is red until you enter a high enough amount? This...

max_block_ex_mem

Cardano has over 40 network parameters. Parameters are the mechanisms that control how the Cardano Blockchain works. In this installment of our Cardano Network Parameters series, we examine max block execution memory (max_block_ex_mem). This parameter sets a limit on how much memory can be used for all scripts within a single block. It helps balance everyday transaction efficiency with the needs of more intense – and perhaps less frequent – tasks. The current value of the max_block_ex_mem is set to...

drep_activity

Cardano has over 40 network parameters–the mechanisms that control how the Cardano Blockchain works. We’ve been exploring each parameter in this series. Our parameter today is the drep_activity governance parameter. In Cardano's recently launched on-chain governance framework, Decentralized Representatives (DReps) are the blockchain's elected opinion-holders. Their job? Vote on governance proposals, signal community priorities, and steer Cardano's decentralized agendas. ## What Is the drep_activity Parameter? Just like a morning roll call at school or the "ping" of a health monitor,...

最大ブロックサイズ

本書の時点で、Cardanoは約30のネットワークパラメータを持っています。 パラメータとは、カルダノ・ブロックチェーンがどのように機能するかを制御する仕組みのことです。 **今日はmax_block_sizeパラメータについて説明します**。 ブロックチェーンシステムは、さまざまなデータをデジタルボックスまたは「ブロック」にまとめ、そのブロックにラベルやメタデータを適用し、最終的にその組み立てられたブロックを多くのコンピュータで複製することで機能します。Cardanoでは、本書の発行時点で、20秒ごとに新しいブロックが世界中の3000以上のコンピュータに複製されています! さまざまな理由から、ほとんどすべてのブロックチェーンは、1つのブロックの大きさを直接制限する。一部のブロックチェーンでは、ブロックサイズの制限は間接的なものです。イーサリアムもそのようなチェーンの1つです。イーサリアムはブロックのサイズを制限するのではなく、ガスと呼ばれるものを制限することで、新しいブロックをパッケージングするのにかかる時間を定義しています。 Cardanoのmax_block_sizeの現在の値は、90112バイトまたは90キロバイトで、45ページの文書やお気に入りのMP3の6秒を保存するのに十分なストレージです。 これはあなたにどのような影響を与えるのでしょうか?お気に入りのブロックチェーンが1つのブロックにどれだけのものを収めることができるかは、ブロックチェーンの使用量が急増したときに、ブロックに入るのを待っている保留中のトランザクションがどれだけの時間滞留するかに影響します。これは、Cardanoのネイティブ通貨であるadaから各国通貨に変換する際にさらに重要です。ほとんどの取引所は、あなたの取引のあるブロックの後にx個のブロックが来るまでは、あなたの資金を凍結します。 ブロックに入るのを待つのが苦手な方は、ブロックが埋まる時間帯を把握しておき、その時間帯に取引を送信しないようにするとよいでしょう。 他の通貨に変換する取引を多く処理する必要がある企業にとって、取引を提出するタイミングを計ることは、為替レートのスリッページを節約することにつながります。 この値を気にするもう一つの理由は、ブロックチェーン上にデータを保存する会社を作ろうとしている場合です。多くのブロックチェーンは、個々のブロックを可能な限り完全に維持することを優先して、大きなトランザクションをスキップするため、情報の断片が小さければ小さいほど、それがブロックに収まる可能性は高くなります。 以上、ダーリントン・コファによるLIDOミニッツでした。英語、キスワヒリ語、エスパニョール語による他のミニッツや誇大広告のないブロックチェーン教育については、lidonation.comをご覧ください。
