Thanks to the growing number of people who @getMaiar & engage with the @ElrondNetwork ecosystem, the number of accounts doubled to over 320k & we’re over 2.5M TXs, an unprecedented adoption level for a 6 months-young mainnet.
#hypergrowth100 Day 40
Weekly #elrondtech ⬇️

 1/ The Delegation Manager toolset has been released for testnet integrations, ahead of our imminent mainnet upgrade. It enables staking providers to set up & manage staking pools, nodes, fees & other parameters for their customers.
https://t.co/FTVIwYWKMh
2/ We updated the libp2p libraries to the latest release & found out that they work seamlessly with their old counterparts. Congrats @libp2p team for the effort put in backward compatibility. We know how complex that is. :handshake:
https://t.co/29I6YRtjud
3/ Redesigned the async call & token transfer syntax in our Arwen WASM VM. Interactions between contracts are now “return types”, which makes execution flow more intuitive. Callbacks have also been redesigned.
https://t.co/wh6BIBeDUd
4/ Arwen WASM VM updates continued:
- Integrated new Arwen and new features of Arwen into elrond-go. Added a set of integration tests for different scenarios.
- Fixed a bug in Arwen VM which did not let one contract to deploy multiple contracts.
5/ - Added unit and integration tests with a smart contract factory example.
- Testing the new Arwen async-calls & promises
- Arwen & elrond-wasm testing of various scenarios involving async calls and ESDT token transfers.
6/ - Made lots of fixes for Arwen's new multi-asyn call infrastructure (Promises).
- Continuous integration improvements - run tests on pull request (arwen-wasm-vm - added; elrond-wasm-rs - in progress)
7/ - Added new features for transferring value or transferring ESDT & calling other (multiple) smart contracts without the asynchronous call & callback functionality. This enables one contract to send & call functionalities from multiple contracts from the same execution
8/ - Improved the mechanism of sending back value to a contract through an asynchronous callback. This value can be any eGLD or ESDT. The treatment works both in and cross-shard

9/ Other notable achievements:
- Worked on the NFT standard for elrond-go. Sharded NFTs where users will keep their one NFTs at their own address. A lot of features here: like creating a brand, creating a marketplace without smart contract (will accept any value - ESDT / eGLD).
10/ - working on a wrapper over the API handler so when the node is syncing after a shuffle out, API endpoints could return messages that signal the node is currently syncing, instead of starting the API webserver only after the sync is finished.
11/ - Testnet release T1.1.28.0 was commissioned that fixes several bugs.
- Updated all other major 3-rd party libraries to their latest versions
- Fixed several tests that had nondeterministic execution paths leading to different code coverage values.
12/ - Finished a trie sync optimization that should decrease the time took by the node to get in sync with the rest of the network.
- Working on an ERC1155 smart contract
- Finalized unit tests for block execution invariant
- Refactored transaction coordinator with arguments
13/ - Tested the delegation manager and delegation SC.
- Ledger Nano S tests after deploying of the latest version.
- Added a response logger middleware on Elrond Proxy so we can have a better overview over failing requests
- Analyzed the runtime memory usage of the Elrond node.
14/ - Added a new endpoint that returns all the key-value pairs stored under a specified address
- Worked on support for Testnet BTC on our fork of Trust Wallet Core (this feature will be used on Maiar).
- Fixed a concurrency issue on Observers, within the VM Querying components
15/ - Minor fixes and extra tests in the wallet utilities of erdjs.
- Sketched a Python prototype for trivial secret splitting (involving one-time pads and basic modular arithmetic) - could be useful for Maiar in the future.
- Working on automatic elrond-sdk docs publishing
16/ - Optimizations on the node names and identities.
- Investigate failed relayed TXs from the backend.
- Refactored API resolvers and adapted the latest changes in economics to the soft restart feature branch.
17/ - Refactoring integrity checks to expose a single CheckIntegrity function
- Create logs parsing tool for bad transactions and used it to identify/debug some user registration failures in Maiar.
- Started to improve overall error logging in elrond-go
18/ - Implemented EIP 2334 javascript module that allows you to derive multiple bls keys from a 24 words mnemonic
- Work on TransactionConverter to replace function references in other components
- Tested different branches to ensure compatibility & protocol overall quality
19/ - Started to refactor different components from elrond-go to ensure clean code quality
- Implemented a disabled node facade for the new API refactoring & the unit tests to ensure code coverage
- Working on chainlink - aggregator smart contract
20/ - Added 2 new github action on the elrond-go repository, one to check if test coverage was increased or decreased and one to ensure if all our 3-rd party modules are up to date
- Continue to working on the task to move all the elastic indexer code in a new repository
21/ - Refactoring transaction status computer component
- Improve error handling and add unit tests
22/ "Stay Hungry Stay Foolish" and tune in soon for more of the #Elrondtech which powers the
@ElrondNetwork ecosystem. Check our progress & get involved 👇

THREAD: 15 of the most useful razors and rules I've found.

Rules of thumb that simplify decisions.

Bezos' Razors:

• If unsure what action to take, let your 80-year-old self make it.

• If unsure who to work with, pick the person that has the best chances of breaking you out of a 3rd world prison.

Skinner's Law:

• If procrastinating on an item, you only have 2 options:

1. Make the pain of not doing it greater than the pain of doing it.

2. Make the pleasure of doing it greater than the pleasure of not doing it.

Luck Razor:

• If stuck with 2 equal options, pick the one that feels like it will produce the most luck later down the line.

I used this razor to go for drinks with a stranger rather than watch Netflix.

In hindsight, it was the highest ROI decision I've ever made.

Bragging Razor:

• If someone brags about their success or happiness, assume it’s half what they claim.

• If someone downplays their success or happiness, assume it’s double what they claim.

The map is not the terrain.

If you're new to real estate twitter this is a must-read.

A thread on how most real estate folks structure deals with outside investors.

Most GPs utilize the "preferred equity" structure when they raise money from outside investors. They "syndicate" deals.

Here's the basics:

The person (or team of people) putting the deal together is the "sponsor". Also called general parter. Referred to on twitter as the GP.

They find the property, do all the work, hire the management company and take fees. They often co-sign debt and always secure the financing.

The investor is generally passive, doing no work and putting in cash. This is the "limited partner". Referred to on twitter as the LP.

They don't co-sign debt. They simply read reports and ask the sponsors questions and cash checks every month (if the deal is going well).

There are two equity classes.

"Preferred equity" belongs to the LPs. Cash talks, so this is a higher class of shares. They are first in the "capital stack" behind the debt (bank loan).

"Common equity" belongs to the sponsor. They are generally last in the capital stack.

Sponsors generally co-invest. That means they hold both equity classes. A 10% co-invest is standard.

That means the GP has skin in the game. His 10% co-invest makes him both an LP and a GP.

1/x The window we have been targeting for 2 months has officially opened... i Can not imagine a more textbook display of the power of Vanna at expiration as we saw on Friday. The capital building was overrun by an insurrection, but all that that meant was a bigger late day rally.


2/x that ended at ATH on the close. Between Gary the 🦍 & his RVol suppression & his hand off to late day Ivol compression & the Vanna index bid, the 🐻’s never had a chance... but Gary’s getting tired after 2 months battling complacency & Vanna’s 2 week vacation, 1 of her only

3/x 2 week departures of the year (a 5 week OpEx) is quickly approaching on 1/15 morning. That means she’ll be increasingly absent as she prepares for her trip. W/ a $59 1 week straddle & $50 1 day range on Friday, & another $30 overnight drop, it’s hard to see why you wouldn’t

4/x want to take a chance on a little long gamma at this juncture. Especially given the obvious warning signs coming from the steepening of the yield curve, underperformance of the Growth complex, complacency in sentiment & positioning, anecdotal signs of bubbles in BTC & TSLA,

5/x NTM the growing exuberance surrounding a fiscal stimulus deal near $2 Trillion. The wall of worry of 3 months ago is gone. The vaccine is being deployed, the election is resolved, fiscal stimulus was passed & w/2 Georgia 🍑 🍑, ever moar 🚁💰is on the way. But what happened

🌺कैसे बने गरुड़ भगवान विष्णु के वाहन और क्यों दो भागों में फटी होती है नागों की जिह्वा🌺

महर्षि कश्यप की तेरह पत्नियां थीं।लेकिन विनता व कद्रु नामक अपनी दो पत्नियों से उन्हे विशेष लगाव था।एक दिन महर्षि आनन्दभाव में बैठे थे कि तभी वे दोनों उनके समीप आकर उनके पैर दबाने लगी।


प्रसन्न होकर महर्षि कश्यप बोले,"मुझे तुम दोनों से विशेष लगाव है, इसलिए यदि तुम्हारी कोई विशेष इच्छा हो तो मुझे बताओ। मैं उसे अवश्य पूरा करूंगा ।"

कद्रू बोली,"स्वामी! मेरी इच्छा है कि मैं हज़ार पुत्रों की मां बनूंगी।"
विनता बोली,"स्वामी! मुझे केवल एक पुत्र की मां बनना है जो इतना बलवान हो की कद्रू के हज़ार पुत्रों पर भारी पड़े।"
महर्षि बोले,"शीघ्र ही मैं यज्ञ करूंगा और यज्ञ के उपरांत तुम दोनो की इच्छाएं अवश्य पूर्ण होंगी"।


महर्षि ने यज्ञ किया,विनता व कद्रू को आशीर्वाद देकर तपस्या करने चले गए। कुछ काल पश्चात कद्रू ने हज़ार अंडों से काले सर्पों को जन्म दिया व विनता ने एक अंडे से तेजस्वी बालक को जन्म दिया जिसका नाम गरूड़ रखा।जैसे जैसे समय बीता गरुड़ बलवान होता गया और कद्रू के पुत्रों पर भारी पड़ने लगा


परिणामस्वरूप दिन प्रतिदिन कद्रू व विनता के सम्बंधों में कटुता बढ़ती गयी।एकदिन जब दोनो भ्रमण कर रहीं थी तब कद्रू ने दूर खड़े सफेद घोड़े को देख कर कहा,"बता सकती हो विनता!दूर खड़ा वो घोड़ा किस रंग का है?"
विनता बोली,"सफेद रंग का"।
तो कद्रू बोली,"शर्त लगाती हो? इसकी पूँछ तो काली है"।

“We don’t negotiate salaries” is a negotiation tactic.

Always. No, your company is not an exception.

A tactic I don’t appreciate at all because of how unfairly it penalizes low-leverage, junior employees, and those loyal enough not to question it, but that’s negotiation for you after all. Weaponized information asymmetry.

Listen to Aditya


And by the way, you should never be worried that an offer would be withdrawn if you politely negotiate.

I have seen this happen *extremely* rarely, mostly to women, and anyway is a giant red flag. It suggests you probably didn’t want to work there.

You wish there was no negotiating so it would all be more fair? I feel you, but it’s not happening.

Instead, negotiate hard, use your privilege, and then go and share numbers with your underrepresented and underpaid colleagues. […]

1/“What would need to be true for you to….X”

Why is this the most powerful question you can ask when attempting to reach an agreement with another human being or organization?

A thread, co-written by @deanmbrody:


2/ First, “X” could be lots of things. Examples: What would need to be true for you to

- “Feel it's in our best interest for me to be CMO"
- “Feel that we’re in a good place as a company”
- “Feel that we’re on the same page”
- “Feel that we both got what we wanted from this deal

3/ Normally, we aren’t that direct. Example from startup/VC land:

Founders leave VC meetings thinking that every VC will invest, but they rarely do.

Worse over, the founders don’t know what they need to do in order to be fundable.

4/ So why should you ask the magic Q?

To get clarity.

You want to know where you stand, and what it takes to get what you want in a way that also gets them what they want.

It also holds them (mentally) accountable once the thing they need becomes true.

5/ Staying in the context of soliciting investors, the question is “what would need to be true for you to want to invest (or partner with us on this journey, etc)?”

Multiple responses to this question are likely to deliver a positive result.
