[Say Hello to Linea, a Developer Friendly zk-Rollup, Powered by ConsenSys](https://linea.mirror.xyz/6G30hwV2wPs_wPv0VEgHYaIdghMkIQaad-OI_0br1hM)
Linea represents the next evolution of ConsenSys zkEVM, powering a new generation of dapps built on Ethereum.
- How can developers use zkEVMs?
Developers can use zkEVMs to execute Ethereum smart contracts without extensive modifications to the underlying logic. They can also access existing blockchain developer tooling or port existing Ethereum contracts to ZK-rollups.
- How are zkEVMs related to zero-knowledge rollups?
ZkEVMs are part of zero-knowledge (ZK) rollups, which are Ethereum layer 2 scaling solutions. They submit transaction data to Ethereum along with zero-knowledge proofs verifying the validity of off-chain transaction batches.
- How do zkEVMs improve throughput?
ZK-rollups transfer computation and state storage off-chain, which improves throughput. Transaction data is submitted to Ethereum along with zero-knowledge proofs verifying the validity of off-chain transaction batches.
- Why is a fully functional zkEVM important?
A fully functional zkEVM will encourage the development of EVM-compatible ZK-rollup projects. This presents advantages such as secure scalability, cheaper costs, faster finality, and leveraging Ethereum's network effects.
- What types of zkEVM exist?
There are several zkEVM projects, each with different approaches to combining EVM execution with zero-knowledge proof computation. Some popular examples include ZkSync's zkEVM and StarkWare's StarkNet.
- 5. What are zkEVM opcodes?
ZkEVM opcodes are low-level machine instructions used for executing programs in an EVM-compatible ZK-rollup. They are designed to be more efficient for use in zero-knowledge proving circuits.
- 4. Why is building zkEVM difficult?
The EVM wasn't built with zk-proof computation in mind, which makes designing a zkEVM circuit difficult. Other challenges include special opcodes, storage overhead, and proving costs.
- 3. What are the three parts of zkEVM?
The zkEVM is divided into an execution environment, proving circuit, and verifier contract. Each component contributes to program execution and proof generation.
- 2. How does zkEVM differ from the Ethereum Virtual Machine?
The Ethereum Virtual Machine (EVM) is the runtime environment for smart contracts on the Ethereum network, while the zkEVM generates zero-knowledge proofs to verify program correctness.
- 🔟 things you missed about zkEVM
1. What is zkEVM?
zkEVM is a virtual machine that generates zero-knowledge proofs to verify the correctness of programs. It supports zero-knowledge technology to execute smart contracts in Ethereum layer 2 scaling solutions.
- Is USDC going to Zero?
The collapse of Silicon Valley Bank (SVB) has led to a bank run and a halt on all withdrawals.USDC, a stable coin,with all reserves backed 1:1 that are meant to be safe, low-risk pegged with a real-world US dollars just announced approximately $3.3bn of their total reserves are held in SVB.
The situation is unfolding in real-time. USDC is currently priced at $0.88-$0.92, leading to panic among Investors.
A bailout solution might occur, which could help in covering all customer deposits and eventually getting all $3.3bn from SVB but who knows when that will happen?
It is normal to feel anxious or concerned during times of financial uncertainty;
1. Remember that crises are temporary and will pass.
2. Avoid obsessively checking news or social media.
3. Connect with loved ones and seek support.

- Best Practices for Securing Your Web3 Wallet
1. Never share your private keys with anyone, as they can be used to steal your funds.
2. Protect your web3 activity from prying eyes by using a virtual private network (VPN), which encrypts your internet traffic.
3. Be cautious of phishing scams: Phishing scams are common in web3. Be wary of unsolicited emails and messages that ask for personal information or request you to visit a particular website.
4. Use a hardware wallet: A hardware wallet is a physical device that stores your private keys offline, making it harder for hackers to steal them.

- Safe is also a popular example with features requiring multiple individuals to sign transactions
- Argent is a popular smart contract wallet with incredible features like that of ERC-4337
- Smart Contract Wallets offer a wide range of possibilities, such as multisig security using trusted Guardians, transfer limits, approval of known addresses, and bundling transactions.
Security wise, Smart Contract Wallets can be locked in the event of theft or loss of a phone to prevent funds from being spent.
- Heard of Smart Contract Wallet (SCW) ?
A smart contract wallet is a type of wallet where code, not a private key, controls the wallet. This allows for technical features like social recovery, transfer limits, and account freezing, making it both user-friendly and secure.
- Do you know with ERC-4337, you utilized the automated payments system through a subscription feature.
Once available this will enable you to set your own subscriptions limits and process them automatically.
- The current state before ERC-4337 is once you lose your keys, you lose your crypto Asset.
ERC-4337 allows you to recover your wallet via various ways: Friends, Family, Lawyers and other Trusted Entities.
- 4 Interesting Benefits of Smart Wallets
1. No need of seed phrases, open a new wallet with Fingerscan/Face ID in no time
2. Maximum Security - You can now setup 2FA for your wallets.
3. You can as well setup daily spending limits.
4. You can enable monthly auto payment using crypto for subscriptions.

- 3. Ultimate Security
The Account security models can be modified to enable spending limits on certain devices, multisig for certain transaction types, and any logic that can be baked into a smart contract.
- Use Cases of Account Abstraction
2. Bundled transactions
Transaction can be done in batch saving you time of approving and signing transactions repeatedly
- Use Cases of Account abstraction
1. Sponsored transactions
Let's say you ran out of Gas, don't panic ! Gas fees can be paid on your behalf in fact with Stablecoins. You can as well pay on behalf of others

- Overall, Smart Accounts aim to simplify the user experience and increase adoption of Ethereum blockchain technology by making it more accessible to non-technical users
- Another feature of Smart Accounts is "Bundling," which allows multiple transactions to be bundled together and only require a single signature. This can make the process of using NFTs or ERC-20 tokens more efficient and secure.
Additionally, it could potentially enable revocation of access in the same bundle, which would be a significant improvement in security for certain use cases.
- Smart Accounts also allow for easy enabling of two-factor authentication and the use of standard smartphone features such as biometrics to gate access to your account. This can help drive mainstream adoption of crypto wallets.
- **Smart Accounts** offer a range of capabilities, including a better wallet recovery option. Instead of relying on seed phrases that regular people find difficult to remember, Smart Accounts enable alternative recovery options such as nominating a trusted group of people who can gain access to the account.
- What is Smart Account Wallet?
At a high level, Smart Accounts, also known as account abstraction under the ERC-4337 proposal, aim to introduce more user-friendly features to the Ethereum blockchain. It was first proposed in September 2021 by Vitalik and other core contributors of the Ethereum Foundation.
