Optimism was introduced in June 2019, and a testnet was released in October 2019. Optimism is open-source, permissionless, and decentralized. Layer 1, in this case, Ethereum, does not need to process each operation, making ultra-high scalability possible without having to worry about gas fees. Optimism is a well-known layer 2 on Ethereum blockchain and uses “optimistic rollups”. Read more here.įor anyone seeking a more advanced platform with lower fees, give BitForex* a try!

This cryptographic proof (called ZK-SNARK) can be easily verified on-chain for correctness, regardless of the size of the data bundle or how much computational power was required for the transactions it contains. Unlike fraud proofs, validity proofs are generated with each bundle and presented with the Layer1 data to prove that all data is correct.
ZK rollups, on the other hand, are based upon a pessimistic view of the world. Remedies in this regard can be provided by intermediaries who, for a fee, payout the user’s funds immediately on Layer1 and take on this waiting time and the risk of an incorrect transaction. In reality, this leads to the consequence that it takes up to seven days to withdraw one’s funds. In direct trade-off to this, is that it takes longer for the transaction to become final on Layer1. The longer this “challenge period” is chosen, the greater the likelihood of preventing the publication of incorrect data on Ethereum’s Layer1. Within a certain period of time, other participants then have the opportunity to prove that the data is incorrect by means of “fraud proof”. Optimistic rollups assume that the bundles of transactions are valid and are published accordingly. Suddenly, Ethereum can scale from what used to be 15 transactions per second (tps) to 3000+ tps - without compromising on security. The result of verifying multiple transactions simultaneously is increased efficiency in parallel, the number of possible transactions that can be executed increases, resulting in increased scalability. This ultimately allows m ultiple transactions to be “aggregated” to a single on-chain transaction. Rollups are a scaling solution where transactions are bundled and compressed off-chain before being verified on the consensus layer. According to Vitalik Buterin (co-founder of Ethereum), the key to Ethereum’s scaling problem can be found in rollups. If Ethereum wants to keep up with the growing competition, innovations are needed. Read more here Optimism: Solving the Blockchain Trilemma Kadena is quite a new Ethereum competitor. Contrary to the philosophy of a blockchain and Web 3.0. In return, the network is significantly faster but centralized. In most cases, the minimum hardware requirements for operating nodes are set so high that only a few players can participate in the network.
Optimized scaling of the Ethereum blockchain and the associated lower transaction fees would lead to increased user-friendliness and the development of new use cases.īlockchain trilemma… choose two! - created by the author Faster Ethereum Killers: Not Really A SolutionĬompeting blockchains such as Solana, Avalanche, Polkadot, and the like, which tend to call themselves Ethereum killers, often optimize with a view to scaling the blockchain and accept an increased level of centrality for this.įantom FTM: Does Fantom solve the Blockchain Trilemma? Faster, decentralized and still secure As the number of transactions increases, the Ethereum network becomes increasingly busy - if users still want to use the Ethereum blockchain, they are forced to pay excessively high transaction fees. Comparable to Bitcoin, the Ethereum blockchain was optimized for security and decentralization, while scalability was sacrificed. For example, if one wants to ensure a certain level of security, it must be understood that, in this case, scalability is inversely proportional to decentralization. In very simplified terms, developers have to decide which of the two of these three properties they want to optimize for. According to this, a blockchain must make compromises in terms of security, scalability, and decentralization. The reason for this scaling problem can be found in the so-called blockchain trilemma. Following the many technical difficulties of the launch, Yuga announced potentially moving its metaverse from Ethereum to its own chain, though details on that development have not been clarified yet.
