It was marketed as an “investment to retire on” to primarily Japanese investors; in fact, 95% of the buyers were of Japanese origin, primarily in the 35-55 age bracket. 2.56% of buyers were Korean, and 2.39% were Chinese. The ICO oversaw a total sale of approximately 26,000,000,000 of the 45,000,000,000 maximum supply of ADA tokens. At the conclusion of the ICO a total of approximately $63 million USD was raised; this puts the price at an average of $0.00242 per ADA, and the market capitalization immediately after the ICO at approximately $109 million USD.
| |
| * While around 26,000,000,000 ADA was sold in the ICO, an additional 5,185,414,108 ADA were [[distributed]] to [[IOHK]], [[Emurgo]], and the [[Cardano Foundation]].

| |
| "[https://testnet.iohkdev.io/plutus/ ''Plutus'']'' is a purpose-built development and execution platform using the functional programming language [[Haskell]]. Designed to enable the creation of [[smart contracts]] on Cardano, Plutus brings the inherent benefits of functional programming – such as reduced ambiguity and easier testing – to smart contracts. During the Goguen era, Plutus will set the stage for smart contracts that are capable of modeling enterprise-level business and finance scenarios. Not only that, but Plutus and Haskell enable the use of the same codebase both on and [[Off-Chain|off-chain]], whereas other [[smart contract]] implementations often require developers to use two or more different languages, reducing efficiency and increasing the likelihood of costly mistakes."''
| |
| === Transaction Details ===
| |
| * Capacity ([[TPS]]): Cardano’s average [[Transaction (Tx)|transaction]] throughput is 10-15 [[transactions per second]]. This is comparable to [[Ethereum (ETH)|Ethereum]]. [[Charles Hoskinson]] has claimed that [[Ouroboros]] (click for more info) can perform at more than 200 transactions per second in a lab [[Sharding|unsharded]]. Also claims it is [https://iohk.io/blog/how-does-casper-compare-to-ouroboros/ much more] secure then [[Ethereum (ETH)|Ethereum's]] [[Casper]]
| |
| * [[Latency]]:
| |
| | |
| === How it works ===
| |
| * [[Consensus]] Algorithm: [[Ouroboros]]. It works with delegated [[stake]] pools. ''"Research [https://cardanoroadmap.com/en/byron/ continues] (9-2019) following the initial paper and Byron era implementation, with new variants of the protocol developed and published gradually."''
| |
| | |
| * From this [http://storeofvalueblog.com/posts/a-deep-dive-into-cardano/ Store of Value blog]:
| |
| ''"Ouroboros is a provably secure [[proof of stake]] algorithm developed by a team of [[IOHK]] scientists led by Prof. [[Aggelos Kiayias]]. The algorithm is backed by a peer reviewed paper. According to Charles Hoskinson, the founder of Cardano, Ouroboros’s paper was rewritten 8 times." ''
| |
| | |
| ''The name Ouroboros comes from the name of an ancient symbol depicting a serpent or dragon eating its own tail. The symbol originated in ancient Egyptian iconography. The name is fitting for this algorithm, since Ouroboros operates in epochs.''
| |
| | |
| ''Each Ouroboros epoch contains a fixed number of slots. Each slot represents a new [[block]]. The slot leader is an account [[staking]] ADA that is responsible for creating the block. Epochs last for 5 days. Slot leaders for an epoch are chosen during the previous epoch. An account’s chance of being chosen is directly tied to the amount of ADA it’s [[Proof-of-Stake (PoS)|staking]].''
| |
| | |
| ''An account can only participate in staking if it has at least 1% of the total supply of ADA. For the accounts that don’t meet that criteria, [[staking pools]] will exist so everyone is compensated for owning ADA. This high minimum staking requirement gives rise to concerns of [[centralization]]. An account can only participate in staking if it has at least 1% of the total supply of ADA. At the current [[Market Cap|market cap]] of $13 billion, one needs to have $130 million worth of ADA to participate in staking. If you assume Cardano will be successful, this number will be significantly higher. Who will be able to afford $130 million worth of ADA? Sure there will be [[Staking Pool|staking pools]] but even staking pools encourage the centralization of wealth. Those participating in the pools will most likely have to pay fees to the pool owner.''
| |
| | |
| ''This minimum [[balance]] requirement also means that at most 100 accounts can participate in staking and because of the power law, it will be much less than 100 accounts that will be staking. There will most certainly be a few entities with exponentially large balances of ADA and the minimum balance requirement will only serve to consolidate their power and control.''
| |
| | |
| ''Ouroboros will initially provide both newly minted ADA and [[transaction fees]] as [[Block Reward|block rewards]]. When the total supply of ADA reaches 45,000,000,000 block rewards will consist only of [[Transaction Fee|transaction fees]].''
| |
| | |
| ''According to [[IOHK]]/[[Cardano Foundation]], Ouroboros is the first provably secure [[Proof of Stake|proof of stake]] algorithm. The team behind Cardano has mathematically proven that the algorithm is safe from all the known proof of stake attack methods including [[Grinding Attack|grinding attacks]], [[Nothing-at-Stake Attack|nothing-at-stake attacks]], and [[Long Range Attack|long range attacks]]. This safety and security should be a very powerful enterprise selling point for Cardano.''
| |
| | |
| ''Ouroboros Praos is an initiative to upgrade Ouroboros. Praos is semi-[[synchronous]], doesn’t require a heavy MPC protocol for randomness and encourages the adoption of a quantum resistant [[signature]] scheme for input endorsers and slot leaders. Praos allows for shorter block times.''
| |
| | |
| ''Ouroboros Hydra is another upgrade to Ouroboros that introduces [[sharding]]. Sharding allows multiple Ouroboros epochs to run at the same time which significantly increases Cardano’s throughput. One of the hardest things to [[figure]] out for sharding is inter-shard communication.''
| |
| | |
| * From this [https://medium.com/on-the-origin-of-smart-contract-platforms/on-the-origin-of-cardano-a6ce4033985c article] (28-12-2017):
| |
| | |
| ''"The design of the Cardano Computation Layer (CCL), Cardano’s smart contracts platform, is heavily focused on making it easier to provide guarantees that a [[Smart Contract|smart contract]] behaves as designed without hidden vulnerabilities. <mark>The CCL consists of two layers: a formally specified [[virtual machine]] and language [[framework]], and formally specified languages that facilitate automated verification of human readable smart contract code.</mark>''
| |
| | |
| ''The lowest layer, called [https://iohk.io/blog/iele-a-new-virtual-machine-for-the-blockchain IELE], provides a [[Virtual Machine|virtual machine]] designed to make building [[Formal Verification|formal verification]] tools easy, and a universal language framework for translating smart contracts from higher-level languages into executable instructions. Research and development of IELE is funded by IOHK and led by UIUC Professor and founder of Runtime Verification, Grigore Rosu. Rosu and team are applying insights from their research on [https://www.ideals.illinois.edu/bitstream/handle/2142/97207/hildenbrandt-saxena-zhu-rodrigues-guth-daian-rosu-2017-tr_0818.pdf KEVM], a formal semantics in the [http://www.kframework.org/index.php/Main_Page K framework] for the [[Ethereum Virtual Machine (EVM)|Ethereum Virtual Machine]], and [https://github.com/kframework/llvm-semantics KLLVM], a formal semantics in K for [http://llvm.org/ LLVM], to build a more secure and efficient virtual machine.''
| |
| | |
| ''Unlike the EVM, which is a [[stack]]-based machine, IELE will be a register-based machine, like LLVM. IELE will have an unbounded number of registers and will also support unbounded integers. Avoiding the use of a bounded stack and not having to worry about stack or arithmetic overflow will make specification and verification of smart contracts significantly easier. Like Ethereum, IELE will use [[gas]] to limit resource usage and prevent [[Denial-of-Service attack (DoS attack)|DoS attacks]]. This presents some challenges to formal verification that are considered “[https://iohk.io/blog/designing-a-new-virtual-machine-and-universal-language-framework tricky but manageable]” by the research team. IELE leverages the K framework to simplify the development of automated tools that verify smart contracts match specifications. This allows IELE to support smart contracts written in any programming language that has a formal semantics in K."''

Speaking on a crowdcast update, he provided 11 dates for the release of Shelley. "Guys wanna know when Shelley is? Let's tell ya," he said today. "June 9, this is when it opens up to everybody. The next date we have for you is June 16, that's when we start putting things together end-to-end.""''

| | |
| === 2020 Outlook ===
| |
| * From this [https://www.altcoinbuzz.io/crypto-news/product-release/cardano-looking-forward-in-2020/ article] (18-1-2020):
| |
| ''"In early 2018, Hoskinson claimed that by 2019 project Cardano would be:''
| |
| # ''Fully [[Decentralized]];''
| |
| # ''Will have [[smart contracts]];''
| |
| # ''Lots of [[liquidity]];''
| |
| # ''[[Multisig]] [[paper wallets]];''
| |
| # ''And Hardware [[Wallet]] support.''
| |
| ''Its 2020 and the project is yet to fulfil all these promises. Nonetheless, it managed to achieve a couple of milestones.''
| |
| | |
| ''Unarguably, the launch of its incentivized [[testnet]] was a tremendous success. Within 24 hours of the testnet going live, 5 billion ADA coins stood [[staked]]. And at press time it has already launched over 500 [[stake pools]].''
| |
| | |
| ''According to the roadmaps and Charles latest [[tweet]], the 2020 focus for the team is:''
| |
| # ''Smart contracts; ''
| |
| # ''Scalability;''
| |
| # ''Decentralization;''
| |
| # ''High assurance;''
| |
| # ''and [[On-Chain Governance|Governance]]."''
| |
| | |
| === Old roadmap ===
| |
| * Cardano used to (2018) lay out three eras in its timeline: the Testnet Era, Bootstrap Era, and Reward Era. The Testnet Era is pretty self-explanatory, Cardano is deployed on a [[testnet|test net]]. However it has now (9-2019) [https://cardanoroadmap.com/en/ pivoted] to a [[roadmap]] of five phases.
| |
| * In the old roadmap Bootstrap Era is when Cardano SL is deployed on the [[mainnet]] BUT it is [[centralized]] in order to maintain security. Only a fixed, predefined set of users have control over the system. The assumption is that security is poor in this era since people are slow to redeem their ADA coins. For the first few months, stakeholders who jointly possess the majority of the ADA stake are mostly not online yet. The [[blockchain]] can be easily attacked if only a small amount of ADA is staked. As consolation to the community, Ouroboros will not provide any [[Block Reward|block rewards]].
| |
| * The Reward Era is when the network is in a completely decentralized and [[trustless]] mode. According to Cardano’s website, ''“the system will receive regular software updates moving forward, and a massive amount of new features will be released”'' in this era. These features would include upgrades to Ouroboros, Cardano’s [[consensus algorithm]], an implementation of Cardano’s control layer, and [[Sidechain|sidechains]].
| |
| | |
| === New roadmap ===
| |
| * As of 9-2019 Cardano has a [[roadmap]] has been [https://cardanoroadmap.com/en/ organized] into five eras: [https://cardanoroadmap.com/en/byron/ Byron] (2017 untill Q1 of 2019), [https://cardanoroadmap.com/en/shelley/ Shelley] (2017-2019), [https://cardanoroadmap.com/en/goguen/ Goguen] (2017 until Q1 of 2020), [https://cardanoroadmap.com/en/basho/ Basho] (2019 until Q3 of 2020), and [https://cardanoroadmap.com/en/voltaire/ Voltaire] (from Q2 of 2018 untill Q4 of 2020). Each era is centered around a set of functionalities that will be delivered across multiple code releases.
| |
| Main components of these five era's are:
| |
| # Bryon: [[Testnet]], the [[Ouroboros]] [[proof-of-stake]] [[consensus]] protocol, ADA cryptocurrency, [[block Explorer|block explorer]], [[Wallet|wallets]].
| |
| # Shelley: [[Staking Pool|Stake Pools]], [https://eprint.iacr.org/2017/573.pdf Ouroboros Praos] (an upgrade), [https://eprint.iacr.org/2018/378.pdf Ouroboros Genesis], [https://eprint.iacr.org/2018/1049.pdf Ouroboros-BFT] (which they claim is a milestone ahead), [[HD Wallet|hierarchical deterministic (HD) wallets]], [[multisig|multi-sig]],
| |
| # Goguen: [https://testnet.iohkdev.io/plutus/ Plutus], Plutus Core Cardano’s [[Smart Contract|smart contract]] virtual machine, a multi-currency ledger ([[ERC20 tokens|ERC20]] like), the [[IELE Virtual Machine|IELE virtual machine]] (which as of 9-2019 has been paused) and the [[KEVM Virtual Machine]] (which as of 9-2019 has been paused).
| |
| # Basho: "Scaling" through [[Sidechain|sidechains]] as a [[sharding]] mechanism. ''"Sidechains can be used as a sharding mechanism by off-loading work from the [[main chain]] onto a [[sidechain]] to increase the capacity of the network." ''Which actually sounds like no actual sharding is happening.
| |
| # Voltaire: introduction of a voting and treasury system; ''"To fund the future development of the network, [https://cardanoroadmap.com/en/voltaire/ Voltaire] will also see the addition of a [https://www.lancaster.ac.uk/staff/zhangb2/treasury.pdf treasury system], whereby a fraction of all [[Transaction Fee|transaction fees]] will be pooled to provide funds for development activities undertaken following the voting process."''
| |
| * [https://www.coindesk.com/cardano-to-launch-hard-fork-before-next-major-development-phase From] [[CoinDesk]] (5-12-2020):
| |
| "''Cardano, [https://roadmap.cardano.org/en/byron/ said] it is set to launch a [[hard fork]] in December as part of the transition to the third development phase of the protocol. Dubbed “Goguen,” the third phase will be focused on the protocol’s integration of smart contracts after building Cardano’s foundation and decentralizing its system in the first two phases. ''
| |
| | |
| ''The [[Hard Fork|hard fork]] will introduce the token-locking mechanism, one of its most significant new functions, to the [[MainNet|mainnet]]. It will enable the network’s smart contracts to support certain conditions such as making users hold tokens for a fixed period of time in order to complete a contract. In addition, the upgrade will bring custom tokens into the network besides its native ADA token, Hammond said.''"

| "''Large Transactions have been steady this year''
| |
| | |
| ''The large transactions (greater than $100k) are always a solid indicator of the health of a crypto asset. The ITB’s large transaction analysis for Cardano shows a relatively “steady” pattern YTD, except for a peak during April, following a [[bull run]] in March in which the price reached $0.09.''
| |
| | |
| ''The Cardano network is growing slowly but it’s active''
| |
| | |
| ''ITB’s Addresses Metrics indicator shows that 49% of the [[addresses]] in the Cardano network are active. Also, during this year, the ratio of new addresses entering the network vs the addresses leaving the network has been slightly positive, but with the launch of Shelley can increase that ratio even more.''
| |
| | |
| ''Large investors in Cardano are “[[Hodling]]”''
| |
| | |
| ''IITB’s Ownership indicators provide a view of a crypto asset’s “capital stack” according to the concentration of the asset. Looking inside Cardano, we can see that there are 42 addresses that hold roughly 40% of the circulating supply.''
| |
| | |
| ''The interesting thing is, that only 3 of these addresses are actively trading, which means that the other addresses have less than 300 [[transactions]] since their creation and plans to hold the token for the long term.''
| |
| | |
| ''Cardano is more popular in “the West”''
| |
| | |
| ''At first glance, you may think that Cardano has a global predominance, but ITB’s East vs West analysis shows that the token is slightly more popular in the West."''

| ''"[The] structure of economic rewards enables the protocol authors to develop several proofs about properties of the system, which has led IOHK to proclaim Ouroboros the “[https://twitter.com/iohk_charles/status/776048255461314560 first provably secure proof of stake algorithm].” The safety and liveness proofs presented are based on assumptions of a [[partially synchronous]] network with an honest majority and an upper limit on how long honest [[nodes]] may be offline. These assumptions may work well for [[Private Blockchain|permissioned blockchains]] and the commercial applications envisioned by [[Emurgo]], but perhaps not as well for a [[permissionless]] world computer. The assumptions underpinning Ouroboros security have been criticized as “[https://news.ycombinator.com/item?id=15946598 unrealistic]”, “[https://twitter.com/jaekwon/status/776174892244803584 impractical for a global blockchain]”, and “[https://twitter.com/VladZamfir/status/812914201412911104 way too convenient]”."''

| |
| * Check out [https://steemit.com/cardamon/@dan/peer-review-of-cardano-s-ouroboros this post] by Larimer on the flaws of Cardano. Also check out [https://hoskinsoncharles.blogspot.com/2018/01/the-price-of-craftsman-and-zen-of.html Hoskinson’s rebuttal].
| |
| * Cardano is built as a layered [[blockchain]]. The Cardano [[Settlement Layer (SL)]] is where account balances and transactions are managed. It uses the [[UTXO]] model and is supposed to be the most secure part of the blockchain. The [[SL]] is kept apart from the computational layer where smart contracts are executed. This layered architecture gives the system the flexibility to be more easily maintained and allow for upgrades by way of [[Soft Fork|soft forks]]. In Ethereum, the settlement layer and the computational layer are intertwined.
| |
| *From this [https://medium.com/on-the-origin-of-smart-contract-platforms/on-the-origin-of-cardano-a6ce4033985c article] (28-12-2017):

| ''"In contrast to Cardano’s approach, [[Casper]] TFG is designed to address the faults that are likely to occur on an open [[public blockchain]], rather than make assumptions that may only hold for [[permissioned]] chains.''
| |
| | |
| ''Whereas Ouroboros and Casper TFG both employ economic rewards to achieve safety and liveness, Casper TFG also incorporates penalties based on fault attribution. Casper TFG is proven safe without any synchrony assumptions and it’s likely to be proven live under partial-synchrony. Moreover Casper TFG assumes no bounds on being offline and addresses attacks from majority coalitions. The design of Casper TFG takes into account faults that are likely to occur on an open public blockchain, rather than making assumptions that may only hold for permissioned chains. Neither Ouroboros nor Casper TFG has been deployed on an open public blockchain with significant assets at stake."''
