A path through the garden
Blockchain.
Transactions, contracts, and the mechanics underneath.
Notes in this topic
25–36 of 37
- Deriving legacy and wrapped-SegWit addresses from WIF
An older BitcoinJS example that chooses a network and constructs P2PKH and P2SH-P2WPKH payments.
Blockchain - Dividend accounting and the gas budget for distribution
An older reflection-token note, separated into accrual, conversion, and bounded distribution work.
Blockchain - ERC165 capability detection is not caller authorization
Why a contract claiming an interface cannot prove that it is the caller your target intended to trust.
Blockchain - IBFT and IBFT 2.0: compare safety and liveness precisely
Correcting an earlier comparison that incorrectly described original IBFT as having no rounds or leader changes.
Blockchain - Paginate contract reads before the collection grows
A Solidity 0.8.3 experiment showing why a view call can still exceed execution or response limits.
Blockchain - Pass RPC authentication through an older Web3 provider
Historical Web3 1.7.4 HTTP/WebSocket and Truffle fragments, with credential and provider-shape defects explicit.
Blockchain / Tools & experiments - PoA and PoS describe validator authority, not every consensus property
Compare membership, economic weight, governance, and finality without inferring them from a label alone.
Blockchain - Separate public RPC access from server credentials
A historical Infura authentication note covering Basic auth, JWT claims, and where signing material belongs.
Cloud & systems / Blockchain - Separate token storage from transfer policy
An older presenter-contract experiment and the authority, state, and migration boundaries it introduces.
Blockchain - Testing ERC-4337 in a local environment
A small account-abstraction experiment: a local chain, a bundler, a mock paymaster, and a Safe smart account.
Blockchain / Tools & experiments - Understanding contract addresses: CREATE and CREATE2
Creation bytecode, constructor arguments, and the difference between a sender nonce and a deterministic deployment salt.
Blockchain - What an ERC165 interface ID actually identifies
Function selectors, interface discovery, and why a support response is a capability claim rather than proof.
