Every step with its proof: a block height, a date, or a source. We keep apart what
already happened, what was measured in trials, and what is only calculated.

The protocol loses its ceiling
The Genesis upgrade strips the block size cap out of the consensus rules and returns most of the original opcodes. Limits become settings each miner chooses, not rules of the protocol.

A 3.87 GB block, and the toll beats the subsidy
188,101 transactions in a single block, near a thousand times BTC's theoretical maximum. It collected 9.71 BSV in fees against a 6.25 subsidy: for the first time on a sustained basis, traffic paid more than issuance. The network's observed peak would later reach 3.99 GB.

First Teranode block on mainnet
TAAL mines the first block in history using Teranode software: 1.2 million transactions in 248.91 MB. Horizontal scaling leaves the lab and enters live consensus.

A 142× surge absorbed without congestion
Daily load goes from 72 MB to 10.3 GB. No queues, no fee auction: the network widens with the traffic.

A second, independent implementation
GorillaPool mines with its own node, written from scratch in GoLang. No single piece of software produces Teranode blocks any more: if one fails, the other does not share the fault.

Chronicle completes the restoration
Satoshi's last original opcodes return, the Original Transaction Digest Algorithm is reinstated, and the script number limit rises from 750 KB to 32 MB. Mandatory for every node; the new functions are optional and nothing existing broke.

Trials
Measured
One million transactions per second
Sustained for two weeks across a globally distributed test network. It is the highest figure actually measured, not estimated.

Calculated
~6 million TPS on the current architecture
Up to 10 million with optimisation, according to the Teranode team. These are calculations on the system as it stands today, not a roadmap promise.
Stated by @BSVTeranode · 7 Jun 2026
Mainnet moves around 2,800 transactions per second today, because that is what demand
asks for. The gap between that number and the ones above is not a technical limit.
It is how much room is left.
