https://www.coindesk.com/tech/2023/03/01/ethereum-activates-account-abstraction-touted-by-founder-buterin-as-key-advance/
The Ethereum blockchain has deployed a feature known as “account abstraction,” seen as a key enhancement that could make it easier for users to recover crypto if they lose private keys to an online wallet.
This proposal just adds a new layer atop Ethereum’s mainnet layer. The goal is to eventually integrate account abstraction into the main protocol.
The contract can be used on all EVM chains, meaning it can be deployed anywhere that is EMV-compatible.
Account Abstraction is a concept that turns users' wallets into smart contract accounts, in order to make Ethereum wallets more user-friendly and to prevent any loss of crypto keys
How Account Abstraction works
- On Ethereum, users can create two types of accounts that hold their crypto: External Owned Accounts (EOA) and Contract Accounts (CA).
- EOAs, which most Ethereum users opt for, are the type of account you use if you open a MetaMask and Coinbase Wallet.
- With EOAs, users are given a pair of private and public keys, and anyone can send crypto to an EOA using their public key. On EOAs, only the owner of their account, the person who has access to their private keys, can initiate transactions.
- CAs on the other hand, are accounts controlled by code – not private keys – so they cannot initiate transactions themselves.
- The issue with EOAs comes down to human error – if a user loses their private keys, there is no way to recover that. Account Abstraction addresses the issues of an EOA account by merging it with a CA – therefore creating built-in mechanisms that can allow users to keep access to their crypto.
- Some of these built-in mechanisms include a social recovery system, where several users have the ability to return access to that account should someone lose their personal private key. Account Abstraction also allows users to create “multisig wallets” that give a group of users access to an account, and require multiple users to sign off on transactions as an extra safety mechanism.

Wallet Concepts
Jim >> wallet implementation currently needs to be rethought for risk and effective operations governance
The concept of wallets as implemented needs to be rethought in my opinion for a variety of scenarios on security, fraud, accessibility, reliability, recovery, operational health governance beyond basic regulatory compliance that are not always covered in different use cases.

AI models need to be TRUSTED
Models will need to be TRUSTED (Targeted, Reliable, Understood, Secure, stress-Tested, Ethical and Durable) to ensure their ethical, safe and effective application across the organisation.
AI use in financial systems - BOE speech
First, the enormous step change in the power, size and complexity of models.
Second, the power of the new AI models brings all data dynamically into scope, both in training and in real-time application.
Third, the ability to interact with some of these AI solutions in natural language means everyone can use them. ( << almost )
The new wave of AI solutions is a reason to double down on strengthening data foundations.
Towards a broader AI strategy. ( << beyond financial transactions but for all use cases ( individual, content, etc ) )
