1/ Oracle, the 2nd largest software provider in the world is working with partners on numerous Central Bank Digital Currency implementations.

I wonder who could have partnered with them? 🤔

🧵👇

$QNT
2/ The above video is from a recent demonstration with Oracle showing how Quant's technology can be used to tokenise assets on Hyperledger Fabric / Oracle Blockchain as well as interoperate with other blockchains.
3/ Quant are one of three Fintech Partners to deliver financial services infrastructure (Quant, Hacera and R3)

Quant are enabling #interoperability of DLTs to deliver mission-critical business applications and workloads for FS clients. ImageImage
4/ Probably nothing...😏 ImageImage
5/ Quant are in talks with one of the largest software companies in the world who want OVL gateways to create an inter-bank network for all their thousands of financial services clients, connecting them all through their gateway to Overledger Network

Wonder who that could be?🤔 ImageImage
5/ Oracle invited Quant to attend the leading financial event of the year - SWIFT SIBOS where Oracle were co-marketing with Quant to take their solution to their 480,000 clients including meetings with Banks / Central Banks Image
6/ Quant are working with and in talks with numerous Central banks such as the Bank of England, as shown below with William Lovell, Head of Technology at the Bank of England in this Hyperledger Trade Finance call
wiki.hyperledger.org/display/TFSIG/…
7/ Quant are involved in the creation of The Digital Pound Foundation.

Likely similar to the Digital Dollar Foundation used to launch pilot programs / explore designs and uses of a U.S CBDC but instead for the UK's Digital Pound CBDC.
8/ As well working with banks (CitiBank🤔)to enable cross border payments as well as work on a Multi-DLT Retail CBDC for the Latin Amercian Dollar

9/ For more info about CBDCs see this thread 👇

1/ Simply having the EVM utilise 100 threads does not mean you get 100x the performance, state growth remains the main bottleneck, so how does $SEI address this?

SEI V2 introduces SEI DB which brings numerous improvements to enable it to scale more than 100x than other EVMs Image
2/ First what is state?

State refers to the current status of the blockchain and includes things such as account balances, smart contract code, and other storage data. (It does not include the history of every tx).

Every time a transaction is processed the relevant data is
3/ retrieved from disk so that the transaction can be executed and then the updated state is written back to disk.

Each transaction also accesses the disk multiple times rather than once, increasing the overhead. As the size of the state grows (via number of accounts increasing

Mid-range modern desktop CPUs come with 16 cores & 32 threads nowadays, yet the current EVM implementations can only utilise just a single thread to process all transactions, sequentially, one after another.

Parallel EVMs enable all threads to be utilised for higher performance
Another way to think about it - imagine a theme park entry with just a single person at a counter checking everyone's tickets to grant them entry. A Bus drops 96 passengers off who seek entry and they form a single long line where each is checked in turn and granted entry
The person at the back of the queue has to wait for 95 others to be processed first.

Now imagine if the theme park had 32 employees and 32 counters all checking everyone's tickets. Instead of a single line 96 deep, there is now 32 much shorter lines of just 3 people deep.

1/ High throughput Parallel EVM chains are going to be big in 2024

But what are the differences / trade-offs between the two most anticipated parallel EVM L1's due to launch, $SEI & $MONAD?

👇🧵outlines overview & differences / trade-offs from someone who intends to own both Image
2/ Standard EVM chains are single threaded & have to process every transaction sequentially one after another. Parallel execution enables many transactions to be processed in parallel, utilising multiple threads/cores that are included with modern CPUs for greater throughput
3/ Parallel transactions are only possible for those that don't touch the same state / conflicting transactions and so for those they would all have to be processed sequentially, however for those that don't touch the same state they can be run in parallel

Decentralisation is largely a theatre at this point - heavy reliance on a few centralised trusted entities - RPC providers, upgradable smart contracts, small multisig oracles / bridges, sequencers, front ends / wallet infra, governance controlled by few large entities etc
2/11
CBDC's are largely misunderstood & crypto people think they are just a tool for governments to spy on your payments, whilst simultaneously advocating the use of payments on public blockchains that have no privacy and not only every government but anyone can track your entire
3/11
payment history and future payments as well as everyone you have interacted with as well.

Given the large number of PoS blockchains there are now with a wide variety of value securing them, how many hacks have there been where PoS has been compromised?

Whereas how many hacks have there been due to smart contract vulnerabilities / multisig/priv keys being compromised?
Don't fall for the shared security meme and think that rollups, dapps etc built on an L1 share the same security as the L1 when they all add their own security assumptions - whether that be through smart contract risk, multisig upgrade rights, centralised sequencer without proofs
If I build a DAPP on Ethereum with admin keys / upgrade rights & steal all the funds, (or there is just a security vulnerability that results in all funds being lost), it should hopefully be clear to all these new people getting into crypto that it doesn't share the same security

A retail CBDC issued by the FED is unlikely to happen anytime soon, and even if they did the impact would be limited (despite all the talk about privacy concerns etc). The vast majority of money used to today is commercial bank money issued by banks and it's far more likely that
banks issue stablecoins (ideally working together to issue a single representation rather than each bank issuing their own) and be backed by a wholesale CBDC with the FED. Whereas retail CBDCs will be designed to not compete with commercial bank money and limited to holding a
small amount (UK is £10,000 - £20,000 max per person), far larger amounts that also can earn interest will be available when issued through banks. This would create easy on/off ramps to crypto, provide safer stablecoins than todays alternatives and enable mass adoption,
