The Timechain/"Blockchain" trilemma:

01 - Decentralization

02 - Security

03 - Speed

Solutions being explored:

On-Chain improvements

01 - SegWit (2017): separates signatures to fit more in each block

02 - Block size increase: debated, but risks centralization

Off-Chain innovations

01 - Lightning Network: instant, low-fee payments off-chain

02 - Payment Channels: peer-to-peer transaction paths

03 - Sidechains: parallel chains linked to Bitcoin for more flexibility

But there are trade-offs:

01 - Lightning needs liquidity + user adoption

02 - Bigger blocks risk fewer full nodes = more centralization

03 - Off-chain methods may reduce trustlessness

Scalability is not just about speed.

It’s about preserving Bitcoin’s mission while enabling global use.

Innovation is key - but not at the cost of freedom.
