Servers cost money. I might bring it back. In the meantime, for anyone interested in CPU mining, check out: ZeldHash available at: zeldhash.com It's also tradeable on Horizon.Market

We're excited to announce that Kontor's file storage system is now live on Bitcoin Signet!

It is now possible to 𝘀𝘁𝗼𝗿𝗲 𝗳𝗶𝗹𝗲𝘀 𝗽𝗲𝗿𝗺𝗮𝗻𝗲𝗻𝘁𝗹𝘆 on the Bitcoin blockchain thanks to @kontornetwork Our scalable perpetual file storage system is now live on Signet. Register, login, upload - three steps to permanent storage. Developers can test the Kontor-Portal-Client library today.

Swaps alone aren't enough to build a functional financial ecosystem. Want to use an Ordinal as collateral for a loan? Provide Runes as AMM liquidity? 𝗞𝗔𝗦𝗧 𝗺𝗮𝗸𝗲𝘀 𝗶𝘁 𝗽𝗼𝘀𝘀𝗶𝗯𝗹𝗲 by wrapping any Bitcoin UTXO into 𝗞𝗼𝗻𝘁𝗼𝗿-𝗻𝗮𝘁𝗶𝘃𝗲 𝗿𝗲𝗰𝗲𝗶𝗽𝘁 tokens that can be traded, pooled, or collateralized at optimistic-consensus speed.

@CounterpartyXCP still exists. Always has been. New upgrade proposals talk w/ @agkrellenstein this this Sunday afternoon 1pm Pacific. Study up, state your case or just listen in. x.com/i/spaces/1nxnR…

@jasonmyersart @ord_io @kontornetwork It's very much a proof of concept. "How Dan we build Bitcoin but for storage?" It's missing key features such as penalties for not storing data you promise to store.

@agkrellenstein @ord_io @kontornetwork What was its purpose according to the docs. Temp storage?

BREAKING: Solana NFT holders are reporting that they cannot access their art that Arweave promised to host for 200 years

Kontor offers a scalable perpetual file storage system that runs directly on the Bitcoin blockchain, incentivized by KOR emissions. You can find out more here: kontor.network/learn/file-sto…

Kontor achieves 1–2 second confirmations and over 1,000 TPS through optimistic consensus and transaction encoding optimizations, all while relying entirely on Bitcoin for finality.

@CounterpartyXCP is going to remain a staple of NFT history far into the future. New upgrade proposals talk w/ @agkrellenstein this this Sunday afternoon 1pm Pacific. Study up, state your case or just listen in. Slick new wallet from @droplister (XCP Wallet) - most features included in a wallet so far!! New projects? - Rare PenPen Agency, Rare Horses? x.com/i/spaces/1qGvv…

Bitcoin Native DeFi: The Future of Metaprotocols Adam Krellenstein at @EthereumDenver 2026

@blockamoto @isabelfoxenduke Yeah, we've considered a bunch of variants! The issue with that model is that the "recipient" of a smart contract function call isn't always (usually) obvious. There's a full spec up at docs.kontor.network, and it'll continue to evolve until we hit mainnet.

@isabelfoxenduke @agkrellenstein The fee prediction market concept is wild. @agkrellenstein have you considered having the stake of failed outcomes sent to the recipients of the predicted transactions instead of burned?

BITCOIN RAILS #51: HISTORY OF METAPROTOCOLS ON BITCOIN I with Counterparty Creator @agkrellenstein 🔗 YOUTUBE: youtu.be/vOUubNr3Q44 🌿 SPOTIFY: open.spotify.com/episode/3scwcA… Metaprotocols on Bitcoin have a long and complex history—stretching far before the launch of Ordinals, the most widely used metaprotocol in Bitcoin’s history. Ordinals’ creator @rodarmor credits much of his inspiration to these early projects—including Yoni Assia’s Colored Coins, @ErikVoorhees Satoshi Dice, and of course, @CounterpartyXCP (widely considered the first NFT protocol) developed by Evan Wagner and Adam Krellenstein. While CounterParty was not originally intended for the use of on-chain art, its use for art developed a cult following—used by projects like RarePepes, which remain some of the most valuable NFTs on the market. cc @ScrillaVentura @theog__ In this interview, I sit down with Krellenstein to review the full history of metaprotocols on Bitcoin—the complex history of the first NFT protocol in history—and why, after a long hiatus from Bitcoin, Krellenstein is back in action with metaprotocol @kontornetwork ...with the aim of giving all Layer 2s a run for their money. In this episode, Adam and I cover: - Why early Bitcoin metaprotocols (pre-Ethereum) didn’t take off for DeFi—and what's different today - His personal experiences with @LukeDashjr and the early “spam wars” of 2014 - Why Adam left the Bitcoin space for 8+ years after the creation of Counterparty, and is making a dramatic return with @kontornetwork this past year - The rise of Pepes—and the pros and cons of frogs in pushing forward DeFi metaprotocols - How Kontor is solving the 10-minute block time issue - Why metaprotocols will ultimately outperform Layer 2s for Bitcoin DeFI 🌶️🌶️ This episode of Bitcoin Rails is powered by: — Best In Slot (@bestinslotxyz) - the leading API for Ordinals and BRC-20 data aggregation and indexing. — Spark (@lightspark) - a statechains implementation advancing Bitcoin-powered payments. — Citrea (@citrea_xyz) - a leading Bitcoin rollup technology and BitVM alliance contributor. 📌 TIMESTAMPS: 00:00 Intro 00:25 How Adam Got Into Bitcoin 03:06 Counterparty: Bitcoin’s First Smart-Contract Meta-Protocol 05:01 History of Mastercoin, Smart Contracts & Counterparty 11:12 Why Adam Built Counterparty 14:02 Early Days of NFTs Projects 17:28 Counterparty’s Pivotal Role in Bitcoin’s History 26:23 Proof-of-Burn and Why XCP Exists 33:50 DAO Hack Reversal & Why Bitcoin’s Ethos Still Wins 36:01 NFTs on Counterparty: Rare Pepes & Community Adoption 38:50 How Ordinals Brought Adam Back Intro Bitcoin 43:25 Counterparty in 2024: Governance, Code Decay & Community Rescue 48:09 The Future of Counterparty 50:43 Kontor: Bitcoin’s Next Gen Metra-Protocol 01:02:46 L2 vs Meta-Protocols 01:04:03 Optimistic Verification & BLS Signatures 01:07:38 WASM vs EVM on Bitcoin: Performance & Ecosystem Design 01:15:16 Bitcoin-Secured File Storage: ZK Proofs & the Roadmap Ahead

@isabelfoxenduke Damn I'm so glad to have had the opportunity to discuss all of these topics that are close to my heart 🫶

Counterparty is easily one of the most influential crypto protocol designs — and not just metaprotocol designs — in Bitcoin's history. Arguably the first true “smart contract” system on the market (and this was pre-Ethereum), there are few people on the planet more qualified to share the history of metaprotocols on Bitcoin than Counterparty’s primary architect and creator, @agkrellenstein. We sat down to cover the history of metaprotocols all the way back to Hal Finney [see vid below]. Interview out tomorrow. Drop a follow so you don’t miss it 🔥

1 sat/vB During the Blocksize Wars, many believed Bitcoin faced an imminent scalability crisis. A decade later, transaction fees remain low and bandwidth is abundant. A reminder that markets and innovation often resolve challenges more effectively than urgency or intervention.
