Forward Blocks – A proposal to increase on-chain settlement capacity by 3584x with a soft-fork

Mark Friedenbach, a bitcoin core developer, proposes a new idea he is calling Forward Blocks, for Bitcoin. It enables all sorts of amazing capabilities via soft-fork. You can read the whole paper here ( http://freico.in/forward-blocks-scalingbitcoin-paper.pdf ) and I believe he will be presenting it this weekend at Scaling Bitcoin.

Here's a snippet from the paper that does a great job summarizing a lot of the potential improvements:

We demonstrated that the idea of forward blocks provides a unifying mechanism that:

• Provides on-chain settlement scaling of up to 3584x current limits as a soft-fork;

• Provides for an (optional) proof-of-work upgrade as a soft fork;

• Limits growth of validation costs with a flexible weight limit;

• Decreases centralization risks through the adoption of sharding; and

• Provides a framework for ledger accounting in future protocol extensions including but not limited to:

– A rebatable fee market with consensus-determined transaction clearing fee rates;

– Confidential transactions for obscuring transaction amounts;

– Mimblewimble, ring signatures, or anonymous spends for obscuring the spend graph; and

– Sidechain value-transfer mechanisms.

While there are many moving parts to this proposal, it is not beyond the level of complexity of prior extensions adopted by bitcoin (e.g. segregated witness), and achieves a variety of benefits comparable in magnitude.

BitMEX Research – SegWit transaction capacity increase compared to Bitcoin Cash – Since the launch of Bitcoin Cash in August 2017, around 6.1 million SegWit transactions have taken place, 20.1% more than the cumulative number of Bitcoin Cash transactions in the period.

Microsoft: “Some blockchain communities increased on-chain tx capacity (blocksize increases), this approach generally degrades the decentralized state & cannot reach the millions… we’re collaborating on decentralized Layer 2 protocols that run atop ‘BTC’ blockchain to achieve global scale”
