1/ I want to give some perspective on the economics of #Chainlink services, both in their existing form today and how it will evolve into the future

This includes many nuances regarding user fees, cost-efficiency, network subsidies, economies of scale, and sustainability

🧵
2/ The ultimate long term goal is that all Chainlink services become self-sustaining through user paid fees

Many services already achieve this today, but how pricing is determined and the role of $LINK in terms of demand for these services is a common question
3/ I'll start with Chainlink Any API as it's the easiest to conceptualize

Any API enables smart contracts to fetch data from any off-chain data source via Chainlink nodes, which can be operated either by DevOps teams or the data providers themselves

1/ A thread on blockchain scalability, decentralization, throughput, gas, and modular blockchains
2/ Blockchains are decentralized computers that execute transactions and maintain a global ledger across a network of nodes

Decentralization is important because it removes central points of control as well as prevents manipulation and arbitrary protocol changes
3/ There's block-producing nodes and non-block producing nodes

The former extends the chain with new blocks of transactions (ensuring liveness)

Both types or nodes execute and validate transactions and blocks

A misconception is that the former type of nodes control the network

@spencernoon The demand/supply ratio of Ethereum's blockspace is higher than any other

Demand is high because of the high level of security from decentralization and network effects

Supply is low because of the social contract of decentralization, achieved by limiting hardware requirements
@spencernoon Other L1 blockchains have lower fees because their demand/supply ratio is lower than Ethereum's

Fee are low because less there's less demand for blockspace (compared to Ethereum) and/or there is a greater amount of blockspace (thus higher hardware requirements)
@spencernoon Monolithic blockchains generally have two paths as adoption rises

Increase blockspace to keep fees low (raise hardware requirements and therefore centralize the network)

Keep blockspace static/low to ensure decentralization, but at the trade off of higher fees

1/ Oracle computation is playing an increasingly important role in the #Chainlink Network

It started with verifiable randomness (VRF), but now we are seeing the rising adoption of Chainlink Keepers

What are Keepers and why do they matter? Find out more below 👇🧵
2/ Chainlink Keepers is a transaction automation solution powered by a decentralized network of oracles

These oracles continuously monitor on-chain smart contracts & trigger their execution based on predefined conditions

This ultimately enables more advanced, feature-rich dApps
3/ Keepers are important because, contrary to popular belief, smart contracts are *not* actually autonomous or self-executing

Rather, they are "asleep" by default, and need to "awoken" to make any state changes or do anything interesting

1/ #Chainlink is widely known for its ability for deliver real world data onto blockchains (e.g. price feeds)

However, its capabilities extend far beyond that to performing trust-minimized oracle computation

This opens up so many possibilities 👇
blog.chain.link/what-is-oracle…
2/ Oracle computation is the process of using decentralized oracle networks (DONs) to perform off-chain computation on the behalf of smart contracts, while being anchored to a blockchain to generate trust-minimization
3/ Just like how data delivery extends the capabilities of smart contracts through added connectivity, oracle computation extends smart contracts with scalability, cost-efficiency, privacy, and additional features that cannot be realistically achieved on a blockchain itself

1/ Today in #Chainlink 🔗

"The research-driven initiative combines @WOOnetwork’s liquidity provision strategies with @Chainlink’s robust oracle technology to create customized Chainlink oracles based on WOO’s market data"

Framework for building DONs
woonetwork.medium.com/woo-network-us…
2/ "The long-awaited @StellarOrg@0xPolygon token bridge, developed by @NwcPublic, is now live on mainnet and has integrated #Chainlink Proof of Reserve to help ensure the highest possible standard of security"
newscrypto.medium.com/newscrypto-int…
3/ "Today, we’re excited to announce that we are integrating #Chainlink Price Feeds as the primary oracle solution for @Indigo_protocol, a synthetic asset protocol being built on @Cardano"
