TensorCash

TensorCash v1.2.4b is now available. It introduces ruleset 6, with dense error checking, historical content non-reuse checks and repetitive entropy filters, to reward higher quality blocks and reduce fork risk. It activates at mainnet block 35,300 (~Tue 10 Nov, 12:00 UTC). Block producers need to upgrade before then, and verifiers should update to support ruleset 6. Until that height, v1.2.4 keeps working.

A miner on the TensorCash network wrote a website for a coding agent on Qwen3.8-27B, and received 0.01136 TSC for this inference. Inference and a shot at the block reward, from the same unit of electricity. A live run by @boblabs_eu, an independent team building on the network.

Network difficulty on TensorCash reached a new all-time high today. More AI inference is running to secure the chain than ever before, and every block still comes with a proof of the model that produced it.

On TensorCash, two people can trade directly, with no one else in between. The funds stay in their own wallets until the trade settles, removing the risk of an exchange losing or freezing them. This video follows one of those trades, from the offer to the block it settled in. One unit of a call option on the network’s difficulty was traded for 0.9 TSC. The option and the TSC moved in one transaction, straight from one wallet to the other. Each trade on the protocol is trustless, and neither side can end up paying without receiving. All in an ordinary transaction, with no escrow, no multisig and no trace of the negotiation, which keeps it cheap and private.

TensorCash v1.2.4 activates today at block 33,378, expected between 09:00 and 11:00 UTC. From that height, nodes run their own validity check on proof-of-inference blocks. Verifiers and bcore block producers who haven’t upgraded yet: the upgrade is mandatory, so do it before then. Pool verifiers: download both pool-verify-pack archives, verify them against SHA256SUMS and extract them into the same directory.

Improved verifier performance for larger models and longer context windows, reviewed together with several miners. TensorCash v1.2.4 activates on Wednesday 28 October at block 33,378, expected around midday UTC. Verifiers and bcore block producers: the upgrade is mandatory, so upgrade before that height.

An independent benchmark by @boblabs_eu showed that mining on TensorCash adds at most 0.3% GPU time to inference. Qwen3.8-27B ran on three GPUs over a full agentic session, once without mining and once with every request mined. GPU time changed by −1.1% to +0.3%. At close to zero overhead cost, a miner can serve inference together with a proof of the model that wrote it, and compete for the block reward at the same time.

Tomorrow at 12:30 ET, early contributors @samjavadi and @enrico_otta join @MCGlive to talk about TensorCash and answer questions about the protocol.

INFERENCEFI has been registered by @inferenceFI as a native asset on TensorCash at block 32,453. Its issuer document, the INFERENCEFI Issuer Charter, is attached to the asset’s Issuer Control Unit (ICU) and describes what the asset is for and the rules it follows, with every version staying recorded on chain. inferenceFI plans to use the native asset to publish index values on chain, and to create child assets under INFERENCEFI.<name>, such as markets, contract legs, outcome tokens and tranches, each with its own terms. Under its rules, inferenceFI publishes what each index measures, and how it is calculated, no later than its first value. The chain confirms that each value came from inferenceFI, and once published, a value can’t be changed. Beyond that, any native asset on TensorCash can, among other things, carry legal documents and holder-only disclosures, require zero-knowledge KYC, let holders vote on changes, and be traded through on-chain spot, repo and forward contracts.

Two models can now be mined on TensorCash: Qwen3-8B and Qwen3.8-27B. The newly added 27B has more than three times the parameters, making it more capable. That also means each 256-token window takes more compute, so a miner would get fewer attempts at a block. To make up for that, and keep both models worth mining from a block reward perspective, its difficulty is set lower. A miner’s chance at a block stays roughly the same on either model.

Questions have come in about community-built web wallets, extensions and EVM bridges. No official EVM bridge for TensorCash has been released. A supported bridge will only be announced here and on tensorcash.org. Until then, no bridge is official.

TensorCash is a proof-of-work chain where the work is AI inference. Miners can sell this inference and get a chance at the next block with the same work. It sets the standard for verifiable inference by attaching a proof of the model used to every answer.

One day after Qwen3.8-27B went live on mainnet, it is already serving paid traffic: a full coding session, served by a TensorCash miner and sold through @AskTillyAI, an independent operator on the network. Every request came with a proof of which model did the work.

Qwen3.8-27B (bf16) is now registered on TensorCash mainnet, a model reported as competitive with today’s top models. From now on, coding and autonomous agent tasks can be bought as inference from the TensorCash network, a large step up from Qwen3-8B. Block producers and miners are advised to upgrade to 1.2.3a-r2 before mining with the new model.

TensorCash 1.2.3 activates today at block 31,400, expected around 13:00 to 15:00 UTC. Verifiers: upgrade to 1.2.3a-r1. Full wallets: upgrade from the release page. After activation, a registration for Qwen3.8-27B (bf16) is planned, with a difficulty multiplier of 50,000.

An early contributor of the protocol signed his first post with a qualified electronic signature, and the proof is stored on TensorCash. The hash of the text, the certificate fingerprint and the signature are in block 31,144. This shows that the exact text was signed and existed at that block, and it cannot be changed or backdated. The certificate ties the signing key to his legal identity. Native assets on TensorCash offer additional rules that every node enforces. Among others, the signed legal document belongs to the asset, no more units can exist than it allows, and it can only change with the holders’ approval.

TensorCash v1.2.3 is out. Multi-model verification, cascading verifier failover, VDF checkpoints and tougher RED block penalties. ⚠️ Upgrade nodes, miners and verifiers before mainnet block 31,400 (~Thu 15 Oct, 12:00 UTC). Qwen3.8-27B mainnet registration follows.
