Cardano evolves through eras, and each one has its theme, Byron was the foundation, Shelley was decentralization, Goguen was programming smart contracts, Voltaire was governance, and Basho was scalability.
Each era marks a new milestone in development, but they all progress in parallel, you don't need to completely finish one to start another, moreover, I would say that they are all always in constant progress and improvement.
This year, 2022, is the year of Basho.
With the Hard Fork Alonzo and the enablement for programming in the Plutus language, it was possible to develop DApps for DeFi.
Although with the NFT airdrops there were spikes in network congestion, the significant and continuous increase in transactional traffic began to be noticed with the appearance of DEXes, MuesliSwap, SundaeSwap and recently ADAX.
As major components, including wallet connectors and the Plutus Application Backend (PAB), are finalized and integrated into the mainnet, further activity is anticipated.
With current parameters, the Cardano network is using, on average, around 90% of its capacity.
Cardano Blockchain Insights
All of this demonstrates the need to improve network scalability, which means processing transactions faster, with lower latency, and without increasing cost.
Part of the scalability is block propagation, which is the time it takes for a newly minted block to be transmitted through nodes on the network. In order for the blockchain to remain secure, the current protocol, Ouroboros Praos, propagates new blocks every 5 seconds.
There is also the block time budget, which is a fixed amount of time available to process all the transactions included in a single block. This is divided between the time that can be used for the execution of the Plutus script and the time that is available to execute other transactions. It is currently set to 1 second.
For security reasons, the Praos consensus protocol selects only a small fraction of the blocks (1 in 20) that could potentially be added to the chain. For current protocol parameters, the maximum transaction throughput (for simple transactions) is approximately 11 transactions per second (TPS).
Hydra provides a more efficient means of processing off-chain transactions while using the main chain ledger as the secure settlement layer.
If you want to know more about Hydra, you can read my article cited at the end (1).
Off-chain computing
The offloading of some of the calculations, for example, with Asynchronous Contract Execution (ACE), can drive greater core network efficiency. Transactions occur outside of the blockchain itself, but can offer fast and cheap transactions through a trusted model.
Mithril
Mithril is the cryptographic construct that allows thin clients (such as non-node wallets) to obtain data from the blockchain, without downloading all of its content.
Synchronizing the blockchain is an intensive operation, because it is a very large information base (currently almost 28 GB), and it is constantly growing. The main problem is to extract only a certain part of the information from the network, for a thin client (without downloading the entire blockchain).
Cryptocurrency holders will include the Mithril keys along with the basic crypto keys (in their wallets). The blockchain will contain the information of UTxOs, the information of the registered accounts, and the Mithril keys.
At regular intervals, the full nodes will collect the UTxOs, and test where they can produce a pre-signature. This test is essential, since not all holders are eligible to issue the signature on a given message, only one set will be chosen at random. Only when there is a sufficient number of pre-signature fragments, which are issued by those chosen, will it be possible to add said fragments to the final "Sigma" signature.
This will improve chain synchronization while maintaining trust, with multi-signature aggregation, which is a fast and efficient way of logging, without compromising security features.
Hard Fork Babbage
Input Output software engineer, Kevin Hammond, commented on Cardano's next steps, revealing that IOHK has a Hard Fork scheduled for February called Babbage, named after mathematician Charles Babbage, considered the father of computers.
