Advanced Encryption Techniques for Blockchain: 7Block Labs’ Whitepaper

the enterprise encryption headache you can’t ignore

Your roadmap says it’s “private-by-design,” but honestly, the tech stack seems to suggest otherwise.

Make sure to encrypt any personally identifiable information (PII) and sensitive trade data throughout the entire process. It's important to keep everything secure while also adhering to SOC 2 Type II and ISO 27001 Annex A 8 standards. 24 evidence requirements. Hold on a sec--rollups are now cramming a bunch of data into those EIP-4844 blobs (KZG). These blobs are temporary and, just so you know, you can't access them through the EVM. Also, there are some exciting upgrades on the horizon that are really going to shake up how calldata pricing operates and how we handle blob throughput. (eips.ethereum.org).

Procurement is currently searching for FIPS-validated modules, and they're looking into a Bring Your Own Key (BYOK) model too. So, what that really means is you need to ensure that your HSM/KMS options can easily integrate with both hybrid post-quantum TLS and cloud FIPS endpoints. And the best part? It all has to happen without putting the brakes on developer speed. (docs.aws.amazon.com).

So here’s the scoop: the security team is really pushing for using threshold keys and MPC wallets to make sure everything runs smoothly. Meanwhile, the engineering crew is zeroing in on getting aggregate signature verification and ZK-friendly hashes up and running. They’re doing this to help keep those on-chain gas fees and proofing costs under control. (ietf.org).

Data teams are on the hunt for ways to get privacy-protecting confirmations from online sources--like banking, payroll, or KYC stuff--while making sure they don't accidentally expose any raw data. But here's the catch: the legal team insists that we need to have solid proof of where that data is coming from. (tlsnotary.org).

missed deadlines, runaway costs, audit gaps

If you're thinking about putting off a solid encryption strategy until after the integration phase, just know that you might be inviting some tricky challenges your way.

Cost Surges: So, here’s the deal--after Dencun, Layer 2 solutions that continue to send unclear data through calldata instead of utilizing blobs might see their gas costs shoot up significantly. We’re talking about anywhere from 10 to 40 gas per byte for those heavy data transactions once EIP-7623 kicks in. It’s something to keep an eye on! On the flip side, when it comes to effective blob pricing, we’re looking at roughly 1 gas per byte. That breaks down to about 2^17 gas for a 128KiB chunk. That’s a huge jump--going from 10x to 40x! You definitely can’t overlook that when you’re discussing the budget. (eips.ethereum.org).
Compliance gaps: Auditors are really raising the bar these days. They’re looking for clear connections to standards like ISO 27001 A.

8. Sure thing! So, we're talking about the 24 and SOC 2 Trust Services Criteria. These are basically standards that help companies ensure they're doing things right when it comes to data security and privacy. They provide a framework for managing customer data and building trust with clients. Pretty important stuff in today’s digital world! What we're talking about here is a pretty comprehensive look at the whole process. We've got logs that cover the key lifecycle, vendor attestations, and a clear trail showing how your encryption policy connects to the actual artifacts. It's way more than just a casual “we turned on AES-GCM." “Hey, just a heads up--if you put off audit remediation until later, you could end up throwing a whole quarter off track.” (isms.online).

Fixing protocol drift: Pectra has introduced EIP‑2537, which brings in those BLS12‑381 precompiles, along with EIP‑7691 to improve blob throughput. Meanwhile, EIP‑7623 is increasing calldata costs. So, if you stick to old ideas and assumptions, you might find yourself facing two costs--once in gas fees and then again in the extra engineering time you'll have to spend to sort it all out. (blog.ethereum.org).
PQC Technical Debt: So, NIST just finished up the final touches on ML‑KEM (that’s FIPS 203), ML‑DSA (FIPS 204), and SLH‑DSA (FIPS 205) in 2024. And guess what? They’re also designating HQC as a backup KEM for 2025. Exciting times ahead! If you decide to put hybrid modes on the back burner right now, you could be setting yourself up for some serious data headaches down the line. Trust me, you don't want to find yourself scrambling for retrofits later! (nist.gov).

7Block Labs’ encryption-by-design methodology

We bring together cryptography with rollup economics, L1/L2 roadmaps, and audit outcomes. So, what's the result? You get total confidentiality throughout the whole process, plus a straightforward return on your investment.

1) Data Classification to Encryption Mode Mapping

Mapping fields to modes: When it comes to the edges, we’re using AEAD. For the FIPS pathways, we typically go with AES-GCM. But if you’re worried about nonce misuse or if you’re working with mobile constraints, then XChaCha20-Poly1305 is definitely the better option. One of the coolest features of XChaCha20 is its extended nonce. This little gem really helps you avoid those frustrating RNG issues, especially when you're working with keys that stick around for a while. Just a quick reminder--make sure to keep it outside the FIPS-scope boundaries when you need to! For more info, just check this out here.
Envelope encryption: This is basically when you take your data keys for each record and securely wrap them up using KMS or HSM, all while making sure you’re using your own keys (that’s the BYOK part). When it comes to using AWS KMS, we usually opt for the FIPS endpoints whenever it's needed. Plus, we always keep track of our TLS setup and any hybrid PQ TLS stuff for our SOC 2 documentation. It's just part of our process to stay organized! If you're looking to explore this topic further, you can find all the details in the documentation here. It's a great resource!

2) Key Management Architecture (FIPS-ready, PQC-ready)

Production KMS/HSM: We're all about keeping things secure! That's why we're using FIPS 140‑3 and FIPS 140‑2 Level 3 modules wherever we need to. We really need to set a clear "cryptographic boundary" when it comes to our audit scope. It's pretty crucial for keeping everything organized and on track. We'll definitely set up key rotation, give you deletion attestations, and keep logs of key usage that meet the ISO 27001 A requirements.

8. 24 evidence sets. If you want to dive deeper into this, feel free to check it out here.

Threshold Control Plane: We’re rolling out TSS for our operators, and we’re using FROST for Schnorr domains. Plus, we’ll be diving into the latest threshold ECDSA variants anytime secp256k1 is in play. We've chosen plans that have clear abort features so we can keep track of our operations and stay accountable. If you want to dive deeper into the details, just check it out here.
PQC Hybrid Roadmap: We're gearing up to handle both transport and at-rest key wrapping, and we're excited to introduce those ML-KEM hybrid handshakes! Also, we're getting ready for the ML-DSA and SLH-DSA code-signing. Exciting stuff ahead! We're going to keep a solid record of everything, paying special attention to how flexible our algorithms are and creating playbooks for re-issuing based on the guidelines from NIST FIPS 203/204/205, along with our notes on HQC selection. If you'd like to dive deeper into the details, check this out here. It’s packed with information!

3) On-chain Confidentiality Patterns That Can Withstand Protocol Changes

EIP-4844 Native Path: So, this method is all about keeping ciphertext outside the EVM by putting it in blobs. Then, we’re linking it to the blockchain using a versioned hash and a KZG proof. Pretty cool, right? It really helps keep state bloat in check, fits nicely with the blob fee market, and gives us a bit of peace of mind when it comes to avoiding any surprises with calldata pricing. If you’re curious and want to get into the nitty-gritty, just click here to check it out!
Verification Hooks: Don't forget to utilize the point-evaluation precompile (0x0A) when you're checking out blobs and KZG proofs. It’s a handy tool to have in your toolkit! Whenever you need to, don't hesitate to use the BLS12-381 precompiles (thanks to EIP-2537) for those aggregate attestations. They can really come in handy! Hey everyone! Just a heads up, this feature is now live on the mainnet in Pectra. Exciting stuff! Check it out here.
Privacy and MEV: If you want to keep your sensitive transactions private, consider using Flashbots Protect RPC to route them through private order flow. It's a smart way to maintain that confidentiality! This really helps to keep those annoying leak-before-encrypt races and sandwich attacks at bay. Don't forget to jot down any builder sharing and status APIs in your runbooks. It's super important to keep everything organized! If you're interested, you can check it out here for more info!

4) ZK Integration Without Blowing the Proving Budget

Hash Choices: Consider switching from Keccak or SHA-256 to Poseidon or Poseidon2 directly in the circuit. This could really help in reducing those constraint counts. Recent benchmarks have shown that this method can significantly cut down both runtime and on-chain costs when it comes to Groth16/Plonk flows. Feel free to dive into the details by clicking here!
Prover Stacks: Check out Plonkish frameworks, like Halo2. They’re pretty cool because they let you throw in custom gates specifically for field arithmetic. It's definitely smart to think of Merkle trees and range checks as something that’s really part of the core of the field. Let's stick with recursion only if it really makes a difference in cutting down those verifier gas costs. If it doesn’t add value, then it’s probably better to keep it simple! If you're looking for more details, just check it out here. You’ll find everything you need!
zkTLS/TLSNotary: If you're handling online data, like bank balances or payroll details, definitely check out TLSNotary or zkTLS. They're super handy! These tools really help you show where your data comes from with selective disclosure, and the coolest thing is, you don’t even have to get the source site on board. Check out all the details right here!

5) Data Availability Choices that Respect Encryption and Retention

Alright, so here’s the scoop on Blob Economics. We’re diving into 128 KiB blobs, targeting about 3 of those bad boys, but we’re putting a ceiling at 6 per block for Dencun. Oh, and just a heads-up: this number got a little boost later with EIP-7691! Hey, just a quick heads up! We're doing an 18-day pruning on the consensus sidecars, so it’s a good idea to get your blob archiving sorted out off-chain. Make sure you plan for that! Take a look at this: eips.ethereum.org.

External DA: If you're exploring modular L2s, you should definitely check out Celestia. Their Data Availability Sampling (DAS) combined with Namespace Merkle Trees (NMTs) really simplifies the process for light clients to verify data availability. It’s pretty cool how this all works together! Hey, just a quick heads-up: it's important to keep your expectations in check when it comes to retention. Light nodes usually only look back about 30 days, so if you need data from further back, you'll want to consider using archival nodes or other providers. Just something to keep in mind! By the way, EigenDA lets you enjoy some free-tier throughput along with a few whitelist protections. Just a quick reminder--make sure to set aside enough bandwidth for those production SLAs! If you’re looking for more details, you can check it out here: docs.celestia.org. It’s got all the info you need!

6) Compliance-by-default evidence pack

Don’t worry, we’ve got you covered with some handy pre-built audit artifacts! You’ll find everything you need, like our cryptography policy, key lifecycle logs, and KMS TLS posture. We’re talking about ciphers, TLS versions, and even those important PQC-hybrid notes - all in one place! On top of that, we've got all the records from the threshold ceremonies documented. We’ve also noted the DA location of record and created traceability matrices that line up perfectly with SOC 2 TSCs and ISO 27001 Annex A 8. It's all organized and easy to follow!

Technical blueprint -- concrete patterns, numbers, and code

1) Blob-First Encrypted Payloads with On-Chain Verifiability

You can go ahead and publish your ciphertext in blobs, and then just keep the versioned hash stored in the L1 transaction metadata. It's a pretty straightforward way to handle it! Just to double-check everything, you can use the point-evaluation precompile (0x0A) that comes from EIP-4844. This approach helps you maintain a nice, tidy permanent state while still making room for any downstream proofs you might need. Right now, you're checking out some pretty interesting parameters. You've got about 128 KiB for each blob, a GAS_PER_BLOB set at 2^17, and there's a blob fee that operates a bit like the EIP-1559 market. It's all kind of fascinating, isn't it? (eips.ethereum.org).

So, what's the deal with blobs over calldata? Well, if you're dealing with data-heavy transactions, you might run into a gas/byte floor of 10/40 due to EIP-7623. But blobs? They’re way more manageable, coming in at around just ~1 gas/byte effective. Much easier on the wallet! Alright, so let's break it down a bit. When you're dealing with stuff like batched telemetry, receipts, or analytics payloads, opting for the encrypt-and-blob method is way more efficient compared to using calldata. And I mean, we're talking a massive difference here! You can check out more about it here.

2) Aggregate authenticity with BLS12‑381 (Pectra and beyond)

If you're juggling a bunch of attestors, like bridge operators and compliance signers, then using BLS to gather all those signatures is definitely the way to roll. It just makes things so much easier! With Pectra, you can easily handle the verification right on-chain, thanks to the EIP-2537 precompiles. So, the pairing checks are sitting around ~37,700 plus 32,600 multiplied by k gas. This actually makes N-of-N attestations a lot easier to handle than doing N ECDSA verifications. Pretty neat, right? If you want to dive deeper into this topic, feel free to take a look here. It's definitely worth a read!

Minimal Solidity Pattern Sketch for Pairing Verification

Let’s dive into a straightforward Solidity pattern you can use for verifying pairs! I've skipped over some of the nitty-gritty details about ABI packing to keep things simple and easy to follow.

pragma solidity ^0.8.0;

import "@openzeppelin/contracts/utils/math/Math.sol";

contract PairingVerifier {
    // Use a struct to represent the Pairing data
    struct Pairing {
        uint256 a1;
        uint256 a2;
        uint256 b1;
        uint256 b2;
        uint256 c1;
        uint256 c2;
    }

    function verifyPairing(Pairing memory pair) public view returns (bool) {
        // Implement your pairing verification logic here
        // For example, you could use some elliptic curve operations

        return true; // Placeholder return value
    }
}

Key Points

The Pairing struct is a handy way to keep all the data you’re going to use organized.
The verifyPairing function is really where everything comes together; this is where the actual verification process takes place.

Don't hesitate to build on this basic framework however you like for your project! Go ahead and get creative!

// Pseudocode: call BLS12_PAIRING_CHECK at 0x0f with packed (G1,G2) tuples
(bool ok, bytes memory ret) = address(0x0f).staticcall(input);
require(ok && ret.length == 32 && abi.decode(ret,(bool)), "bad BLS agg");

Gas Schedule Reference

G1 add: 375
G2 add: 600

When it comes to pairing, here’s what you’ll need to use:

Base: 37,700
Per Pair: 32,600

Oh, and don’t forget to use MSM precompiles when you're aggregating public keys on a larger scale. It's super important! If you’re looking for more info, you can check this out: EIP-2537.

3) Threshold Control for Operator Risk

When it comes to handling wallet and sequencer tasks, it's smart to use a two-round FROST setup for Schnorr, wherever you can. It just makes things a lot smoother! Another option you might consider is the modern threshold ECDSA. This version comes with identifiable-abort features that can help you avoid those frustrating failures that can leave you scratching your head. This method really helps reduce the risk associated with relying on just one operator, and it makes rotating keys super easy--plus, you don’t have to worry about any downtime! Feel free to dive into more details by clicking here. Happy reading!

4) ZK‑friendly primitives

Hey there! If you’re looking to enhance your circuits, consider switching out Keccak/SHA-256 for Poseidon or Poseidon2, especially for tasks like Merkle trees and commitments. It could really up your game! This switch is a game-changer! It can seriously reduce the number of constraints and speed up proof times, especially when you're working with Groth16 or Plonk setups. Honestly, just go with Keccak for those few times when you really need to double-check those external commitments. (eprint.iacr.org).

When you’re setting up your proving system, I'd recommend using Plonkish (Halo2) and don’t forget to sprinkle in some custom gates for those field operations. It’ll really level up your setup! When it comes to using recursion, it's best to tread carefully and only go for it when it really makes sense. For example, if you're looking at how aggregator proofs can help reduce on-chain gas costs over time--like with weekly rollups of attestations--then it could be a smart choice. Just make sure you know what you're getting into! (github.com).

Data you can verify from the web, like info on KYC, payroll, or banking. You can totally use TLSNotary or zkTLS to create a handy proof that confirms something like "the balance is over X" or "I'm currently employed," and the cool part is, you don’t have to show any raw HTML or JSON. We take care of this off the blockchain, and then smart contracts can use a quick proof along with any signatures that might be needed. Take a look at it here: tlsnotary.org. You might find it really interesting!

6) DA Layering with Retention Guarantees

Celestia: So, light nodes are set up to check availability, and there's actually a cool plan in the works. They’re aiming for a 30-day sampling window, which will help when they route those historical queries to archival nodes or providers. Pretty neat, right? If you're diving into high-throughput rollups, you should definitely check out EigenDA! They've got some pretty neat options, including a free tier--just be sure to get yourself whitelisted first! Plus, there's reserved bandwidth to keep things running smoothly. These features are super helpful for handling unexpected surges before you decide to invest in paid throughput. Feel free to dive deeper into this topic by checking it out here.

7) PQC‑ready execution and distribution

Hey there! It's a great moment to dive into hybridizing your systems! You might want to check out ML-KEM for your KEM handshakes - it's perfect whether you're handling transport or storage. And when it comes to code signing, ML-DSA or SLH-DSA could be just what you need. Give them a shot! Hey, just a quick reminder--make sure you’ve got an algorithm agility registry set up, along with some easy-to-follow migration runbooks. They'll be super helpful! All of this will really start to take shape with NIST's final standards rolling out in 2024 (that's FIPS 203, 204, and 205) and then we'll see the HQC selection happening in 2025. Exciting times ahead! Hey there! If you're working in procurement, it’s a good idea to check in with vendors about their support timelines. Just ask them for some proof to back it up. It can really help you feel more secure about their commitment! If you're curious to learn more about this, head over to nist.gov for all the details!

Example A: Encrypted Supplier Invoices with Blob DA + BLS Attestations

Ingest: We’re implementing AES-GCM at the edge and using envelope encryption for line items. You can even bring your own key through KMS, which is pretty cool! Hey, if you want to dive into the details, just click here. It's got all the info you need!
Settlement: We bundle up ciphertext into blobs and only store the versioned hashes in our Layer 1 transactions. More on that here.
Keeping it Real: Every week, compliance officers team up to sign off on a digest with BLS signatures. Instead of going through 50 ECDSA verifications, we can simplify things by just doing one on-chain pairing check to confirm the aggregated signature. It's a much smoother and more efficient way to get the job done! Thanks to the EIP-2537 gas schedule, the verification gas costs are now slashed by around 10 to 20 times when you have a group of 50 signers. That's a pretty big deal! If you want more details, you can check it out here.
Audit: We offer mappings for ISO 27001 A.

8. You’ve got 24 items to check out, which cover things like key rotations, your KMS TLS setup, and attestation logs. Plus, I’ve included links to the SOC 2 TSC for your reference. If you want to dive deeper into the details, just check out this link: this link. It's got all the info you need!

Example B: Private Payroll Proofs for On-Chain Grants

Provenance: So, employees can easily whip up TLSNotary/zkTLS proofs that show they're employed, all right from the HR portals. This way, the verifier will only see the exact fields they really need to check out. Take a look at this link: (tlsnotary.org). You'll find some cool info over there!
ZK Path: We're using in-circuit Poseidon Merkle proofs, which helps us keep the verification costs down for those eligibility lists. These contracts can take a compact proof and distribute grants without having to sift through any personal information at all. If you're looking for more information, check it out here: eprint.iacr.org. There's a ton of useful details waiting for you!
MEV/Privacy: So, here’s the deal: all the submissions go through Flashbots Protect RPC. This little trick helps us avoid any pesky frontrunning while we’re in those grant windows. If you're curious to dive deeper into this, check out the details over at docs.flashbots.net. There’s a lot of great info waiting for you!

Example C: PQC-Ready Custody and Inter-Org Approvals

Keys: So, we’re diving into TSS, and we’ve got a couple of options on the table: FROST/Schnorr or threshold ECDSA. Plus, we’re all set for some emergency rotation if needed. To keep our data safe, we're using KMS for secure storage that wraps everything up nicely. Plus, at the transport layer, we’re taking it a step further with a hybrid ML-KEM approach. If you want to dive deeper into the details, you can check it out here.
Controls: We've got the FIPS 140-3 boundary all laid out, and we've also gathered some solid SOC 2 evidence that covers all the important key lifecycle details and access logs. If you're interested in learning more, check out this website for some additional info: NIST. It's a great resource!

Emerging best practices -- what to standardize in your design reviews

If you've got data that doesn't really need to hang out in the EVM, try the "blob-first" approach. It’s a smart move! You can save your calldata for the paths you control. It’ll help things run smoother. Make sure to keep an eye on EIP-7691--it’s all about boosting blob throughput. Staying ahead of this could really help you avoid any capacity headaches later on! (blog.ethereum.org). So, you can think of EIP‑7623 as your go-to guide for budgeting. It’s all about using encryption and blobs to dodge those annoying calldata floors, especially when you're handling big batches of encrypted data. (eips.ethereum.org). Hey there! So, if you're anticipating a good number of signers, I would totally recommend using BLS aggregates. They really streamline things! The EIP‑2537 precompile makes multi-signature verification a breeze by reducing those O(N) ECDSA calls down to just one pairing check. Super handy, right? (eips.ethereum.org). When you're diving into ZK, make sure to stay on top of your hash hygiene! It’s a good idea to use Poseidon(2) for hashing while you're in-circuit, and only bring out Keccak when you're at the boundaries. Trust me, it'll make a difference! Just this change can really speed up how quickly you generate proof and lower those on-chain gas fees. (arxiv.org). Hey there! Just a quick reminder for KMS: when you’re putting together your SOC 2 evidence, don’t forget to jot down your TLS versions, cipher suites, and any PQC-hybrid endpoints you’re using. It’s also super helpful to spell out your BYOK and rotation SLAs in your vendor contracts. This way, everything’s clear and above board! (docs.aws.amazon.com).

For sensitive payloads, it's a good idea to automatically set up private order flow. Right now, Flashbots Protect RPC is the best option out there and has a solid integration with a lot of relayer tools. (docs.flashbots.net). If you're thinking about DA neutrality, you might want to check out Celestia for those DAS-first designs. It’s a great option. And for a bit more flexibility with blob throughput, EigenDA could be the way to go. Just a heads-up: it's really important to think about your archival storage. Ethereum tends to do its blob pruning every 18 days, so you’ll want to keep that in mind while planning. (docs.celestia.org). Hey there! Just a quick reminder to stay on top of PQC agility. It’s important to focus on NIST’s ML‑KEM, ML‑DSA, and SLH‑DSA. Also, keep an eye on how the HQC standardization is progressing. And don’t forget to update your cryptographic policies and CI/CD signing processes to match the latest versions. Cheers! (nist.gov).

GTM metrics and outcomes we commit to

When we put this methodology into practice, we like to keep an eye on three main areas: how much it costs, whether we’re sticking to the rules, and how fast we’re getting things done.

Difference in data availability costs. If you shift those encrypted payloads from calldata to blobs, you could see some seriously significant savings--think about 10 to 40 times lower costs--especially for transactions that involve a lot of data. The reason for this is EIP‑7623's floors, especially when you compare it to blob gas, which is about 1 gas for each byte. We'll take a look at how you usually post and make sure to allow for some wiggle room with the blob base fee. (eips.ethereum.org).
On-chain verification gas Hey there! So, rather than having to run through N ECDSA verifications, we can actually simplify things by using just one BLS pairing check thanks to EIP‑2537. Pretty neat, right? So basically, this means that the verification gas remains pretty stable at around 37,700 plus 32,600 times k, which is a lot more consistent than the 21k to 30k range we see with ECDSA. Pretty interesting, right? If you're teaming up with about 10 to 50 signers, you might be able to slash verification gas costs by anywhere from 60% to 85%. How cool is that? Before we hop onto the mainnet, we're going to run a few tests in a testnet environment. (eips.ethereum.org).
The cost and speed of ZK proofs. So, check this out: if you replace Keccak with Poseidon(2) in the circuit, recent benchmarks show some pretty impressive results. It looks like you could actually cut proof generation, runtime, and on-chain costs by as much as 73% in specific EVM deployments. That's a huge saving! We'll figure out how much you could save by looking at your particular circuits. (arxiv.org).
Compliance cycle time Hey there! So, we've picked up on something interesting: when it comes to the prebuilt ISO 27001 A, we’ve seen some pretty cool results.

8. The 24/SOC 2 evidence packages, which include important stuff like key lifecycle details, your TLS setup, vendor attestations, and where your data is accessed from, can really help streamline the audit process. In fact, they can reduce all that back-and-forth chatter by about 25% to 40%. Pretty cool, right? Auditors really like being able to trace things directly from the clauses to the artifacts. It makes their job a lot easier! (isms.online).

Delivery predictability
We've got a "no rework" guarantee for any changes tied to Pectra-class updates. Now that we've got blob throughput adjustments (EIP-7691) and BLS precompiles (EIP-2537) built into the architecture, we can steer clear of those complicated patch-level migrations. (blog.ethereum.org).

So, we've got a couple of things to unpack here! First off, there’s the EIP-4844 parameters. This is all about optimizing how Ethereum handles certain transactions. Then, there's the KZG point-evaluation precompile--yeah, that's a mouthful! Basically, it's a way to speed things up when it comes to checking data. And lastly, we can't forget about the blob gas market. This is where things get a bit more technical, but it’s all about how gas fees are managed when dealing with blob data. Pretty interesting stuff, right? (eips.ethereum.org). Just a quick update: starting from October 2023, we’re looking at a new floor for calldata costs with EIP-7623. Plus, we’re also gearing up for the activation of the Pectra EIPs, specifically EIP-2537 and EIP-7691. Exciting times ahead! (eips.ethereum.org).

SOC 2 Trust Services Criteria and ISO 27001 Annex A 8. 24 control expectations. (aicpa-cima.com). Just a heads up about AWS KMS: it’s important to keep an eye on the FIPS posture and the TLS guidelines. Also, don’t forget about the PQC hybrid endpoints! They’re worth checking out. (docs.aws.amazon.com).
The FROST threshold scheme, also known as RFC 9591. (ietf.org).
We're wrapping up the PQC standards, and we've also got the HQC backup KEM in the works. (nist.gov).
Check out the Flashbots Protect RPC documentation! (docs.flashbots.net).
Let's chat about Celestia DAS and NMTs, as well as how retention is looking. Also, we'll touch on EigenDA's throughput and free tier options. (docs.celestia.org).
