Code on Twitter's site reveals how an upcoming Edit button could work: by making a new tweet with the updated content and listing the old tweets before the edit
This month, Twitter announced the ground-shaking news that it was actually going to offer users a way to edit tweets — a longtime user request.

Context & Ripple Effects
Twitter had already said it had been developing the feature since the prior year and planned a Twitter Blue Labs test. The code points to the product-design choice behind that effort: preserving prior versions rather than silently overwriting a post.
Later coverage shows that design becoming a constrained Blue feature, with a five-edits-in-30-minutes limit and an accessible edit history. That makes the implementation detail consequential for how Twitter balances correction against the permanence of public posts.
First-order effects
Twitter users would be able to correct a post through an updated version while readers can see the earlier tweets associated with the edit.
Twitter would retain a visible record of changes, limiting the ability to revise a public statement without context.
Second-order effects
Making edit history part of the interface raises the value of the feature for users who need corrections while preserving a verification trail for readers and publishers who rely on quoted tweets.
The later decision to test editing through Twitter Blue means the capability also becomes part of the subscriber proposition, rather than a uniform change for all accounts.
Third-order effects
A versioned-edit model would establish public-post editing as a controlled revision system: platforms can offer correction tools without treating the original publication as disposable.
If subscription-gated rollout persists, core posting controls may increasingly be used to differentiate paid social-platform tiers.
The trend: Social platforms are moving toward editable public posts with auditable version histories, often rolling the controls out first through paid tiers.
Looks like Twitter's approach to Edit Tweet is immutable, as in, instead of mutating the Tweet text within the same Tweet (same ID), it re-creates a new Tweet with the amended content, along with the list of the old Tweets prior of that edit
@wongmjane Makes sense to me; keeping the same ID would be a nightmare for caching systems based entirely on the tweet ID, and this sounds pretty similar to how retweets work under the hood
After a year+ of hearing that no one wants immutable records of their message history from a minority of @Panquake critics, the fact that Twitter is going to do this is very lol... if it weren't for the fact that Twitter corp can still do historic revisionism with no transparency…
People are up in arms in the replies, but this seems...smart? One of the main arguments against editable tweets is lack of accountability. This approach retains all prior versions. https://twitter.com/...
