+## [DRAFT] security considerations for **[pectra](https://eips.ethereum.org/EIPS/eip-7600)** (q1/25)
+
+<br>
+
+* ✅🔐🏋🏻‍♀️ **[eip-2537: precompile for bls12-381 curve operations, by a. vlasov et al.](https://eips.ethereum.org/EIPS/eip-2537)**
+  - add bls signature verification and operations over bls12-381, a cryptographic primitive allowing to get 120+ bits of security for operations 
+  - security: notes on constant time (tba)
+
+<br>
+
+* ✅🔐🤝🏋🏻‍♀️ **[eip-6110: supply validator deposits on chain, by m. kalinin et al.](https://eips.ethereum.org/EIPS/eip-61100)**
+  - faster for validators to deposit their eth (12 hours -> 30 min)
+  - security: data complexity, dos, weak subjectivity period (tba)
+
+<br>
+
+* ✅🔐🏋🏻‍♀️ **[eip-7002: execution layer triggerable exits, by djrtwo et al.](https://eips.ethereum.org/EIPS/eip-7002)**
+  - improve ux for validators, giving them more flexibility
+  - security: impact on existing custody relationships, fee overpayment (tba)
+
+<br>
+
+* ✅🔐🤝 **[eip-7251: increase the `MAX_EFFECTIVE_BALANCE`, by m. neuter et al.](https://eips.ethereum.org/EIPS/eip-7251)**
+  - biggest ux improvement for validators
+  - raise the validator stake limit (maximum effective balance from 32 -> 2048 eth, with reward compounding)
+  - potentially can reduce the number of inactive nodes and possibly improving the network efficiency
+  - security: attestation committees, aggregator selection, proposer selection probability, sync committee selection probability, churn invariants, fee overpayment (tba)
+
+<br>
+
+* ✅🔐🤝 **[eip-7549: move committee index outside attestation, by dappling](https://eips.ethereum.org/EIPS/eip-7549)**
+  - shuffle the consensus message, making it more efficient
+  - security: first block after fork, mutation over gossip (tba)
+
+<br>
+
+* ✅🔐🤝🏋🏻‍♀️ **[eip-7702: set eoa account code, by vub et al.](https://eips.ethereum.org/EIPS/eip-7702)**
+  - improve the functionality of crypto wallets by giving them smart contract properties (the so called "account abstraction")
+  - more usability in crypto, enhanced security features:
+    - batching (allowing multiple operations from the same user in one atomic transaction)
+    - sponsorship (an account can pay for a transaction on behalf of another account)
+    - privilege de-escalation (users can sign sub-keys and given them specific permissions that are much weaker than global access to the account)
+  - e.g.: gas fees could be outsourced to services to pay on another erc-20 token
+  - security: secure delegation, `tx.origin`, sponsored tx relayers, frontrunning initialization, tx propagation (tba)
+
+<br>
+
+* ✅🤝🏋🏻‍♀️ **[eip-7742: uncouple blob count between cl and el, by a. stokes](https://eips.ethereum.org/EIPS/eip-7742)**
+  - extend functionalities from blobs
+  - execution layer no longer verifies data blobs’s maximum value and instead gets this value dynamically from the consensus layer
+
+<br>
+
+* ✅🏋🏻‍♀️ **[eip-7685: general purpose execution layer requests, by lightclient](https://eips.ethereum.org/EIPS/eip-7685)**
+  - boost the interoperability between the execution and the consensus layer (helping with surge demand on the execution layer)
+
+<br>
+
+* ✅🏋🏻‍♀️ **[eip-2935: save historical block hashes from state, by vub et al.](https://eips.ethereum.org/EIPS/eip-2935)**
+  - increase amount of data from past blocks that can be stored on new blocks
+  - set the stage for verkle tree
+  - improves solo staking ux: enabling stateless validator clients, allowing staking nodes to run with very little hard disk space and quick sync
+  - security: notes on branch poisoning (tba)
+
+<br>
+
+* ✅🤝 **[eip-7594: peerdas - peer data availability Sampling, by djirtwo et al.](https://eips.ethereum.org/EIPS/eip-7594)**
+  - allow beacon nodes to perform data availability sampling, improving how da is handled across the network
+  - crucial feature for layer 2s (making them more efficient and cost-effective)
+  - compare to celestia (tba)
+ 
+<br>
+
+* ✅ **[eip-7692: evm object format meta, by a. beregszaszi et al.](https://eips.ethereum.org/EIPS/eip-7692)**
+  - add a bunch of evm object format for smart contract deployment and execution efficiency
+  - include optimized code validation, better function handling, more efficient data access instructions
+
+<br>
+
+* 🟡 **[eip-7623: increase calldata cost, by t. wahrstätter et al.](https://eips.ethereum.org/EIPS/eip-7623)**
+  - increasing the calldata cost for transactions (increase the cost of calldata to 10/40 gas for transactions that do not exceed a certain threshold of gas spent on evm operations)
+  - highligting data availability
+
+<br>
+
+* 🟡 **[eip-7762: increase `MIN_BASE_FEE_PER_BLOB_GAS`, by maxy riesnick](https://eips.ethereum.org/EIPS/eip-7762)**
+  -  speed up discovery on blob space
+  -  security: "rollups that use blobs as da will need to update their posting strategies"
